How to deploy RSWebParts.cab manually?

- by denni

I'm using the SSRS 2005 Web parts to display my reports in a MOSS 2007 SP1 Portal. I have successfully installed the Web parts in my development, testing, and UAT servers using the following command: stsadm -o addwppack -filename path/to/RSWebParts.cab. But when I tried running the same command in the production server, it will give me the following error: This solution contains no resources scoped for a Web application and cannot be deployed to a particular Web application. I know I usually will get this kind of error message when I tried to deploy my custom solutions having no Web application resources (such as web.config entries) to a specific Web application. But this is not my custom solution, it is an out-of-the-box SSRS Web part and it does have resources scoped to a Web application. I tried to even use different combination of the command by providing the -url, -globalinstall, and -force switches but it still give the same error. The configuration of the 4 servers are exactly the same, both from software and hardware perspectives. All other features are working properly on the production server. I even tried to extract the cab file manually to the bin folder of my Web application, then modify the Web.config manually to include the SafeControl element (copied from the manifest.xml inside the cab file). But it gave me an error saying it couldn't find the resources file. Even though, I extracted the whole file, including the resource files in the bin folder. Is there anyone who can help me resolve the problem? Thanks a lot.

Need help with WCF design

- by Jason

I have been tasked with creating a set of web services. We are a Microsoft shop, so I will be using WCF for this project. There is an interesting design consideration that I haven't been able to figure out a solution for yet. I'll try to explain it with an example: My WCF service exposes a method named Foo(). 10 different users call Foo() at roughly the same time. I have 5 special resources called R1, R2, R3, R4, and R5. We don't really need to know what the resource is, other than the fact that a particular resource can only be in use by one caller at a time. Foo() is responsible to performing an action using one of these special resources. So, in a round-robin fashion, Foo() needs to find a resource that is not in use. If no resources are available, it must wait for one to be freed up. At first, this seems like an easy task. I could maybe create a singleton that keeps track of which resources are currently in use. The big problem is the fact that I need this solution to be viable in a web farm scenario. I'm sure there is a good solution to this problem, but I've just never run across this scenario before. I need some sort of resource tracker / provider that can be shared between multiple WCF hosts. Any ideas from the architects out there would be greatly appreciated!

Maven jaxb generate plugin to read xsd files from multiple directories

- by ziggy

If i have xsd file in the following directories src/main/resources/xsd src/main/resources/schema/common src/main/resources/schema/soap How can i instruct the maven jaxb plugin to generate jaxb classes using all schema files in the above directory? I can get it to generate the class files if i specify one of the folders but i cant get i dont know how to include all three folders. Here is how i generate the files for one folder: <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <schemaDirectory>src/main/resources/xsd</schemaDirectory> </configuration> </plugin> I tried adding multiple entries in the element but it just ignores all of them if i do that. Thanks

Enabling new admin action(button sales_order/view) in ACL

- by latvian

Hi, We created new action similar to 'hold', 'ship' and others in the 'sales_order/view' admin section that can be triggered by clicking at the button. Afterward, we added our new action to the ACL with the following code in config.xml: <acl> <resources> <admin> <children> <sales> <children> <order> <children> <actions translate="title"> <title>Actions</title> <children> <shipNew translate="title"><title>Ship Ups</title></shipNew> </children> </actions> </children> <sort_order>10</sort_order> </order> </children> </sales> </children> </admin> </resources> </acl> ACL functionality works, however, in the 'Resources Tree'(System/Permissions/Roles/Role Resources) our new action does never show up as selected(checked) even thou it is allowed for particular Role. I can see that from table 'admin_rule' with resource id for our new action that it is allowed, so it needs to be selected, but it is not. When trying to solve this issue i looked into the template(permissions/rolesedit.phtml) and I found that the 'resource tree' is draw with Javascript...thats where i got stock due to my limited knowledge in Javascript. Why the resource tree does not display our new ACL entry correctly, that is the check box is never checked? Thank You for helping margots

How to specify path for file from different project in WPF?

- by MartyIX

Hello, I've got two projects in WPF and one project is the main one and the second one is just for testing (it uses files of the main project - files are added via Project - add - Existing items... - selected file - add as link so that the file is only in the main project really). Folders with projects are these: C:\Work\...\Projects\Main C:\Work\...\Projects\XXXTestProject where XXX stands for different parts of the Main project which I test separately. I've got the code: <Window x:Class="Sokoban.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:Sokoban" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" Title="Window1" Height="559" Width="419"> <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="GameDesk.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Window.Resources> <Grid> <Rectangle local:GameDeskProperties.FieldSize="30" Name="myrect" Style="{DynamicResource GameDesk}" MouseEnter="Rectangle_MouseEnter" /> </Grid> </Window> ... which should use XAML resources from GameDesk.xaml which is in the main project and it seems that I can't use Pack URI (http://msdn.microsoft.com/en-us/library/aa970069.aspx). How can I specify the file? Should I use absolute path? (C:\Work...\Main\Resources\GameDesk.xaml) Or is there any other way? Thank you for help!

Does XAML work with file links in Visual Studio?

- by Tim

I'm adding a new WPF project to an existing Visual Studio solution and would like to reuse a bunch of code (C# and xaml) from an existing project within the solution. I've created the new project and added existing files as follows: Right click project Add - Add Existing Item Find the file to reuse, use the arrow next to "Add" and "Add as Link" I now have a nice project set up with all the proper links. However, XAML chokes on these links. For example: <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Resources\Elements\Buttons\Buttons.xaml" /> <ResourceDictionary Source="Resources\Elements\TextBox\TextBox.xaml" /> </ResourceDictionary.MergedDictionaries> The files "Buttons.xaml" and "TextBox.xaml" exist as links in my new project. The project builds, but when I run, I get the following XamlParseException: 'Resources\Elements\Buttons\Buttons.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'. Cannot locate resource 'resources/elements/buttons/buttons.xaml'. It seems like the XAML parser is requiring an actual copy of these XAML files to exist in my new project, instead of links. This is exactly what I'm trying to avoid. I want my project to share these files so that any changes get transferred to the other project without hunting and copying. Any insight is appreciated!

Simple POSIX threads question

- by Andy

Hi, I have this POSIX thread: void subthread(void) { while(!quit_thread) { // do something ... // don't waste cpu cycles if(!quit_thread) usleep(500); } // free resources ... // tell main thread we're done quit_thread = FALSE; } Now I want to terminate subthread() from my main thread. I've tried the following: quit_thread = TRUE; // wait until subthread() has cleaned its resources while(quit_thread); But it does not work! The while() clause does never exit although my subthread clearly sets quit_thread to FALSE after having freed its resources! If I modify my shutdown code like this: quit_thread = TRUE; // wait until subthread() has cleaned its resources while(quit_thread) usleep(10); Then everything is working fine! Could someone explain to me why the first solution does not work and why the version with usleep(10) suddenly works? I know that this is not a pretty solution. I could use semaphores/signals for this but I'd like to learn something about multithreading, so I'd like to know why my first solution doesn't work. Thanks!

WPF ResourceDictionary and DynamicResource

- by lanicor

i am new to WPF so maybe this will be "noob" question but i can't find answer to it (and it seems so easy)... well i am programing WPF app and i want to use smth similar to css for webpages, so i found ResourceDictionary and tried to use it... I have main window in which i create Frame and on click some UserControl is loaded to that same Frame.I include my ResourceDictionary (root/style/Styles.xaml) to my main window like this: <Window.Resources> <ResourceDictionary x:Key="styles" Source="style/Styles.xaml" /> </Window.Resources> in which i have: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Style x:Key="ProductsRequired" TargetType="{x:Type Label}"> <Setter Property="Height" Value="28" /> ... I don't use it on my main window but want to use it on my UserControls, which are loaded to that main window and i try to use it like this: <Label Name="product1" Style="{DynamicResource ProductsRequired}" /> Warning i am getting all the time is: The resource "ProductsRequired" could not be resolved. I even tried including Styles to my UserControl <UserControl.Resources> <ResourceDictionary x:Key="styles" Source="../style/Styles.xaml" /> </UserControl.Resources> and nothing happens... Well my question is long but i wanted to be clear... :) P.S. all that logic works in C# code btw private ResourceDictionary myStyles = new ResourceDictionary(); Style ProductsRequired = myStyles["ProductsRequired"] as Style; product1.Style = ProductsRequired;

Jquery thumbnail popup on link Mouseover

- by Charles Marsh

Hello All, I have this peice of coding which simply swaps an image when a link is clicked, I also show some hidden html content which is positioned over the image. <script> if($.browser.msie && parseInt($.browser.version) <= 6){ $('#contentone, #contenttwo, #contentthree, #contentfour, .linksBackground').hide(); } $('#contentone, #contenttwo, #contentthree, #contentfour').hide(); $("#linkone").click(function() { $('#contenttwo, #contentthree, #contentfour').hide("1500"); $("#imageone").attr("src","Resources/Images/TEMP-homeOne.jpg"); $("#contentone").show("1500"); }); $("#linktwo").click(function() { $('#contentone, #contentthree, #contentfour').hide("1500"); $("#imageone").attr("src","Resources/Images/TEMP-homeTwo.jpg"); $("#contenttwo").show("1500"); }); $("#linkthree").click(function() { $('#contentone, #contenttwo, #contentfour').hide("1500"); $("#imageone").attr("src","Resources/Images/TEMP-homeThree.jpg"); $("#contentthree").show("1500"); }); $("#linkfour").click(function() { $('#contentone, #contenttwo, #contentthree').hide("1500"); $("#imageone").attr("src","Resources/Images/TEMP-homeFour.jpg"); $("#contentfour").show("1500"); }); </script> Does anyone know how I can further modify this to show a small thumbnail image when the user rolls over the link? I just need a hint because I'm not sure where to turn to... can I achieve it with mouseover?

Creating android app Database with big amount of data

- by Thomas

Hi all, The database of my application need to be filled with a lot of data, so during onCreate(), it's not only some create table sql instructions, there is a lot of inserts. The solution I chose is to store all this instructions in a sql file located in res/raw and which is loaded with Resources.openRawResource(id). It works well but I face to encoding issue, I have some accentuated caharacters in the sql file which appears bad in my application. This my code to do this : public String getFileContent(Resources resources, int rawId) throws IOException { InputStream is = resources.openRawResource(rawId); int size = is.available(); // Read the entire asset into a local byte buffer. byte[] buffer = new byte[size]; is.read(buffer); is.close(); // Convert the buffer into a string. return new String(buffer); } public void onCreate(SQLiteDatabase db) { try { // get file content String sqlCode = getFileContent(mCtx.getResources(), R.raw.db_create); // execute code for (String sqlStatements : sqlCode.split(";")) { db.execSQL(sqlStatements); } Log.v("Creating database done."); } catch (IOException e) { // Should never happen! Log.e("Error reading sql file " + e.getMessage(), e); throw new RuntimeException(e); } catch (SQLException e) { Log.e("Error executing sql code " + e.getMessage(), e); throw new RuntimeException(e); } The solution I found to avoid this is to load the sql instructions from a huge static final string instead of a file, and all accentutated characters appears well. But Isn't there a more elegant way to load sql instructions than a big static final String attribute with all sql instructions ? Thanks in advance Thomas

auto_complete plugin error: Couldn't find Question with ID=auto_complete_for_tag_tag_name

- by bgadoci

I have successfully set up this plugin before so I am curious as to what I am doing wrong here. I have built the ability for users to add tags to questions. I am not using tagging plugin here but that shouldn't matter for this. With respect to the auto complete, I am trying to have the form located in the /views/questions/show.html.erb file access the Tags table and display entries in the tags.tags_name column. When I begin to type in the field I get the following error message: Processing QuestionsController#show (for 127.0.0.1 at 2010-05-31 15:22:20) [GET] Parameters: {"tag"=>{"tag_name"=>"a"}, "id"=>"auto_complete_for_tag_tag_name"} Question Load (0.1ms) SELECT * FROM "questions" WHERE ("questions"."id" = 0) ActiveRecord::RecordNotFound (Couldn't find Question with ID=auto_complete_for_tag_tag_name): app/controllers/application_controller.rb:15:in `init_data' For some reason I am actually passing the field name as the Question.id. The plugin set up is fairly simple as you add the following line to your controller: auto_complete_for :tag, :tag_name and the following line in your routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } I have added the controller line to both my tags and questions controller and also mapped resources for both tags and questions in my routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } map.resources :questions, :collection => {:auto_complete_for_tag_tag_name => :get } I have played around with removing either or of the above but can't seem to fix it. Any ideas what I am doing wrong here?

updating a column in a table only if after the update it won't be negative and identifying all updat

- by Azeem

Hello all, I need some help with a SQL query. Here is what I need to do. I'm lost on a few aspects as outlined below. I've four relevant tables: Table A has the price per unit for all resources. I can look up the price using a resource id. Table B has the funds available to a given user. Table C has the resource production information for a given user (including the number of units to produce everyday). Table D has the number of units ever produced by any given user (can be identified by user id and resource id) Having said that, I need to run a batch job on a nightly basis to do the following: a. for all users, identify whether they have the funds needed to produce the number of resources specified in table C and deduct the funds if they are available from table B (calculating the cost using table A). b. start the process to produce resources and after the resource production is complete, update table D using values from table C after the resource product is complete. I figured the second part can be done by using an UPDATE with a subquery. However, I'm not sure how I should go about doing part a. I can only think of using a cursor to fetch each row, examine and update. Is there a single sql statement that will help me avoid having to process each row manually? Additionally, if any rows weren't updated, the part b. SQL should not produce resources for that user. Basically, I'm attempting to modify the sql being used for this logic that currently is in a stored procedure to something that will run a lot faster (and won't process each row separately). Please let me know any ideas and thoughts. Thanks! - Azeem

Exploring the Excel Services REST API

- by jamiet

Over the last few years Analysis Services guru Chris Webb and I have been on something of a crusade to enable better access to data that is locked up in countless Excel workbooks that litter the hard drives of enterprise PCs. The most prominent manifestation of that crusade up to now has been a forum thread that Chris began on Microsoft Answers entitled Excel Web App API? Chris began that thread with: I was wondering whether there was an API for the Excel Web App? Specifically, I was wondering if it was possible (or if it will be possible in the future) to expose data in a spreadsheet in the Excel Web App as an OData feed, in the way that it is possible with Excel Services? Up to recently the last 10 words of that paragraph "in the way that it is possible with Excel Services" had completely washed over me however a comment on my recent blog post Thoughts on ExcelMashup.com (and a rant) by Josh Booker in which Josh said: Excel Services is a service application built for sharepoint 2010 which exposes a REST API for excel documents. We're looking forward to pros like you giving it a try now that Office365 makes sharepoint more easily accessible. Can't wait for your future blog about using REST API to load data from Excel on Offce 365 in SSIS. made me think that perhaps the Excel Services REST API is something I should be looking into and indeed that is what I have been doing over the past few days. And you know what? I'm rather impressed with some of what Excel Services' REST API has to offer. Unfortunately Excel Services' REST API also has one debilitating aspect that renders this blog post much less useful than it otherwise would be; namely that it is not publicly available from the Excel Web App on SkyDrive. Therefore all I can do in this blog post is show you screenshots of what the REST API provides in Sharepoint rather than linking you directly to those REST resources; that's a great shame because one of the benefits of a REST API is that it is easily and ubiquitously demonstrable from a web browser. Instead I am hosting a workbook on Sharepoint in Office 365 because that does include Excel Services' REST API but, again, all I can do is show you screenshots. N.B. If anyone out there knows how to make Office-365-hosted spreadsheets publicly-accessible (i.e. without requiring a username/password) please do let me know (because knowing which forum on which to ask the question is an exercise in futility). In order to demonstrate Excel Services' REST API I needed some decent data and for that I used the World Tourism Organization Statistics Database and Yearbook - United Nations World Tourism Organization dataset hosted on Azure Datamarket (its free, by the way); this dataset "provides comprehensive information on international tourism worldwide and offers a selection of the latest available statistics on international tourist arrivals, tourism receipts and expenditure" and you can explore the data for yourself here. If you want to play along at home by viewing the data as it exists in Excel then it can be viewed here. Let's dive in. The root of Excel Services' REST API is the model resource which resides at: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model Note that this is true for every workbook hosted in a Sharepoint document library - each Excel workbook is a RESTful resource. (Update: Mark Stacey on Twitter tells me that "It's turned off by default in onpremise Sharepoint (1 tickbox to turn on though)". Thanks Mark!) The data is provided as an ATOM feed but I have Firefox's feed reading ability turned on so you don't see the underlying XML goo. As you can see there are four top level resources, Ranges, Charts, Tables and PivotTables; exploring one of those resources is where things get interesting. Let's take a look at the Tables Resource: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Tables Our workbook contains only one table, called ‘Table1’ (to reiterate, you can explore this table yourself here). Viewing that table via the REST API is pretty easy, we simply append the name of the table onto our previous URI: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Tables('Table1') As you can see, that quite simply gives us a representation of the data in that table. What you cannot see from this screenshot is that this is pure HTML that is being served up; that is all well and good but actually we can do more interesting things. If we specify that the data should be returned not as HTML but as: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Tables('Table1')?$format=image then that data comes back as a pure image and can be used in any web page where you would ordinarily use images. This is the thing that I really like about Excel Services’ REST API – we can embed an image in any web page but instead of being a copy of the data, that image is actually live – if the underlying data in the workbook were to change then hitting refresh will show a new image. Pretty cool, no? The same is true of any Charts or Pivot Tables in your workbook - those can be embedded as images too and if the underlying data changes, boom, the image in your web page changes too. There is a lot of data in the workbook so the image returned by that previous URI is too large to show here so instead let’s take a look at a different resource, this time a range: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Ranges('Data!A1|C15') That URI returns cells A1 to C15 from a worksheet called “Data”: And if we ask for that as an image again: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Ranges('Data!A1|C15')?$format=image Were this image resource not behind a username/password then this would be a live image of the data in the workbook as opposed to one that I had to copy and upload elsewhere. Nonetheless I hope this little wrinkle doesn't detract from the inate value of what I am trying to articulate here; that an existing image in a web page can be changed on-the-fly simply by inserting some data into an Excel workbook. I for one think that that is very cool indeed! I think that's enough in the way of demo for now as this shows what is possible using Excel Services' REST API. Of course, not all features work quite how I would like and here is a bulleted list of some of my more negative feedback: The URIs are pig-ugly. Are "_vti_bin" & "ExcelRest.aspx" really necessary as part of the URI? Would this not be better: http://server/Documents/TourismExpenditureInMillionsOfUSD.xlsx/Model/Tables(‘Table1’) That URI provides the necessary addressability and is a lot easier to remember. Discoverability of these resources is not easy, we essentially have to handcrank a URI ourselves. Take the example of embedding a chart into a blog post - would it not be better if I could browse first through the document library to an Excel workbook and THEN through the workbook to the chart/range/table that I am interested in? Call it a wizard if you like. That would be really cool and would, I am sure, promote this feature and cut down on the copy-and-paste disease that the REST API is meant to alleviate. The resources that I demonstrated can be returned as feeds as well as images or HTML simply by changing the format parameter to ?$format=atom however for some inexplicable reason they don't return OData and no-one on the Excel Services team can tell me why (believe me, I have asked). $format is an OData parameter however other useful parameters such as $top and $filter are not supported. It would be nice if they were. Although I haven't demonstrated it here Excel Services' REST API does provide a makeshift way of altering the data by changing the value of specific cells however what it does not allow you to do is add new data into the workbook. Google Docs allows this and was one of the motivating factors for Chris Webb's forum post that I linked to above. None of this works for Excel workbooks hosted on SkyDrive This blog post is as long as it needs to be for a short introduction so I'll stop now. If you want to know more than I recommend checking out a few links: Excel Services REST API documentation on MSDNSo what does REST on Excel Services look like??? by Shahar PrishExcel Services in SharePoint 2010 REST API Syntax by Christian Stich.

Oracle recently announced Oracle Enterprise Manager Plug-in for Amazon Web Services (AWS) allows you to achieve that goal. The on-premise Oracle Enterprise Manager (EM12c) acts as a single tool to get a comprehensive view of your public AWS resources as well as your private cloud resources. By deploying the plug-in within your Cloud Control environment, you gain the following management features: Monitor EBS, EC2 and RDS instances on Amazon Web Services Gather performance metrics and configuration details for AWS instances Raise alerts and violations based on thresholds set on monitoring Generate reports based on the gathered data Users of this Plug-in can leverage the rich Enterprise Manager features such as system promotion, incident generation based on thresholds, integration with 3rd party ticketing applications etc. AWS Monitoring via this Plug-in is enabled via Amazon CloudWatch API and the users of this Plug-in are responsible for supplying credentials for accessing AWS and the CloudWatch API. This Plug-in can only be deployed on an EM12C R2 platform and agent version should be at minimum 12c R2.Here is a pictorial view of the overall architecture: Amazon Elastic Block Store (EBS) Amazon Elastic Compute Cloud (EC2) Amazon Relational Database Service (RDS) Here are a few key features: Rich and exhaustive list of metrics. Metrics can be gathered from an Agent running outside AWS. Critical configuration information. Custom Home Pages with charts and AWS configuration information. Generate incidents based on thresholds set on monitoring data. Discovery and Monitoring AWS instances can be added to EM12C either via the EM12c User Interface (UI) or the EM12c Command Line Interface ( EMCLI) by providing the AWS credentials (Secret Key and Access Key Id) as well as resource specific properties as target properties. Here is a quick mapping of target types and properties for each AWS resources AWS Resource Type Target Type Resource specific properties EBS Resource Amazon EBS Service CloudWatch base URI, EC2 Base URI, Period, Volume Id, Proxy Server and Port EC2 Resource Amazon EC2 Service CloudWatch base URI, EC2 Base URI, Period, Instance Id, Proxy Server and Port RDS Resource Amazon RDS Service CloudWatch base URI, RDS Base URI, Period, Instance Id, Proxy Server and Port Proxy server and port are optional and are only needed if the agent is within the firewall. Here is an emcli example to add an EC2 target. Please read the Installation and Readme guide for more details and step-by-step instructions to deploy the plugin and adding the AWS the instances. ./emcli add_target \ -name="<target name>" \ -type="AmazonEC2Service" \ -host="<host>" \ -properties="ProxyHost=<proxy server>;ProxyPort=<proxy port>;EC2_BaseURI=http://ec2.<region>.amazonaws.com;BaseURI=http://monitoring.<region>.amazonaws.com;InstanceId=<EC2 instance Id>;Period=<data point periond>" \ -subseparator=properties="=" ./emcli set_monitoring_credential \ -set_name="AWSKeyCredentialSet" \ -target_name="<target name>" \ -target_type="AmazonEC2Service" \ -cred_type="AWSKeyCredential" \ -attributes="AccessKeyId:<access key id>;SecretKey:<secret key>" Emcli utility is found under the ORACLE_HOME of EM12C install. Once the instance is discovered, the target will show up under the ‘All Targets’ list under “Amazon EC2 Service’. Once the instances are added, one can navigate to the custom homepages for these resource types. The custom home pages not only include critical metrics, but also vital configuration parameters and incidents raised for these instances. By mapping the configuration parameters as instance properties, we can slice-and-dice and group various AWS instance by leveraging the EM12C Config search feature. The following configuration properties and metrics are collected for these Resource types. Resource Type Configuration Properties Metrics EBS Resource Volume Id, Volume Type, Device Name, Size, Availability Zone Response: Status Utilization: QueueLength, IdleTime Volume Statistics: ReadBrandwith, WriteBandwidth, ReadThroughput, WriteThroughput Operation Statistics: ReadSize, WriteSize, ReadLatency, WriteLatency EC2 Resource Instance ID, Owner Id, Root Device type, Instance Type.

Exploring the Excel Services REST API

- by jamiet

Over the last few years Analysis Services guru Chris Webb and I have been on something of a crusade to enable better access to data that is locked up in countless Excel workbooks that litter the hard drives of enterprise PCs. The most prominent manifestation of that crusade up to now has been a forum thread that Chris began on Microsoft Answers entitled Excel Web App API? Chris began that thread with: I was wondering whether there was an API for the Excel Web App? Specifically, I was wondering if it was possible (or if it will be possible in the future) to expose data in a spreadsheet in the Excel Web App as an OData feed, in the way that it is possible with Excel Services? Up to recently the last 10 words of that paragraph "in the way that it is possible with Excel Services" had completely washed over me however a comment on my recent blog post Thoughts on ExcelMashup.com (and a rant) by Josh Booker in which Josh said: Excel Services is a service application built for sharepoint 2010 which exposes a REST API for excel documents. We're looking forward to pros like you giving it a try now that Office365 makes sharepoint more easily accessible. Can't wait for your future blog about using REST API to load data from Excel on Offce 365 in SSIS. made me think that perhaps the Excel Services REST API is something I should be looking into and indeed that is what I have been doing over the past few days. And you know what? I'm rather impressed with some of what Excel Services' REST API has to offer. Unfortunately Excel Services' REST API also has one debilitating aspect that renders this blog post much less useful than it otherwise would be; namely that it is not publicly available from the Excel Web App on SkyDrive. Therefore all I can do in this blog post is show you screenshots of what the REST API provides in Sharepoint rather than linking you directly to those REST resources; that's a great shame because one of the benefits of a REST API is that it is easily and ubiquitously demonstrable from a web browser. Instead I am hosting a workbook on Sharepoint in Office 365 because that does include Excel Services' REST API but, again, all I can do is show you screenshots. N.B. If anyone out there knows how to make Office-365-hosted spreadsheets publicly-accessible (i.e. without requiring a username/password) please do let me know (because knowing which forum on which to ask the question is an exercise in futility). In order to demonstrate Excel Services' REST API I needed some decent data and for that I used the World Tourism Organization Statistics Database and Yearbook - United Nations World Tourism Organization dataset hosted on Azure Datamarket (its free, by the way); this dataset "provides comprehensive information on international tourism worldwide and offers a selection of the latest available statistics on international tourist arrivals, tourism receipts and expenditure" and you can explore the data for yourself here. If you want to play along at home by viewing the data as it exists in Excel then it can be viewed here. Let's dive in. The root of Excel Services' REST API is the model resource which resides at: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model Note that this is true for every workbook hosted in a Sharepoint document library - each Excel workbook is a RESTful resource. (Update: Mark Stacey on Twitter tells me that "It's turned off by default in onpremise Sharepoint (1 tickbox to turn on though)". Thanks Mark!) The data is provided as an ATOM feed but I have Firefox's feed reading ability turned on so you don't see the underlying XML goo. As you can see there are four top level resources, Ranges, Charts, Tables and PivotTables; exploring one of those resources is where things get interesting. Let's take a look at the Tables Resource: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Tables Our workbook contains only one table, called ‘Table1’ (to reiterate, you can explore this table yourself here). Viewing that table via the REST API is pretty easy, we simply append the name of the table onto our previous URI: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Tables('Table1') As you can see, that quite simply gives us a representation of the data in that table. What you cannot see from this screenshot is that this is pure HTML that is being served up; that is all well and good but actually we can do more interesting things. If we specify that the data should be returned not as HTML but as: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Tables('Table1')?$format=image then that data comes back as a pure image and can be used in any web page where you would ordinarily use images. This is the thing that I really like about Excel Services’ REST API – we can embed an image in any web page but instead of being a copy of the data, that image is actually live – if the underlying data in the workbook were to change then hitting refresh will show a new image. Pretty cool, no? The same is true of any Charts or Pivot Tables in your workbook - those can be embedded as images too and if the underlying data changes, boom, the image in your web page changes too. There is a lot of data in the workbook so the image returned by that previous URI is too large to show here so instead let’s take a look at a different resource, this time a range: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Ranges('Data!A1|C15') That URI returns cells A1 to C15 from a worksheet called “Data”: And if we ask for that as an image again: http://server/_vti_bin/ExcelRest.aspx/Documents/TourismExpenditureInMillionsOfUSD.xlsx/model/Ranges('Data!A1|C15')?$format=image Were this image resource not behind a username/password then this would be a live image of the data in the workbook as opposed to one that I had to copy and upload elsewhere. Nonetheless I hope this little wrinkle doesn't detract from the inate value of what I am trying to articulate here; that an existing image in a web page can be changed on-the-fly simply by inserting some data into an Excel workbook. I for one think that that is very cool indeed! I think that's enough in the way of demo for now as this shows what is possible using Excel Services' REST API. Of course, not all features work quite how I would like and here is a bulleted list of some of my more negative feedback: The URIs are pig-ugly. Are "_vti_bin" & "ExcelRest.aspx" really necessary as part of the URI? Would this not be better: http://server/Documents/TourismExpenditureInMillionsOfUSD.xlsx/Model/Tables(‘Table1’) That URI provides the necessary addressability and is a lot easier to remember. Discoverability of these resources is not easy, we essentially have to handcrank a URI ourselves. Take the example of embedding a chart into a blog post - would it not be better if I could browse first through the document library to an Excel workbook and THEN through the workbook to the chart/range/table that I am interested in? Call it a wizard if you like. That would be really cool and would, I am sure, promote this feature and cut down on the copy-and-paste disease that the REST API is meant to alleviate. The resources that I demonstrated can be returned as feeds as well as images or HTML simply by changing the format parameter to ?$format=atom however for some inexplicable reason they don't return OData and no-one on the Excel Services team can tell me why (believe me, I have asked). $format is an OData parameter however other useful parameters such as $top and $filter are not supported.

J2EE Applications, SPARC T4, Solaris Containers, and Resource Pools

- by user12620111

I've obtained a substantial performance improvement on a SPARC T4-2 Server running a J2EE Application Server Cluster by deploying the cluster members into Oracle Solaris Containers and binding those containers to cores of the SPARC T4 Processor. This is not a surprising result, in fact, it is consistent with other results that are available on the Internet. See the "references", below, for some examples. Nonetheless, here is a summary of my configuration and results. (1.0) Before deploying a J2EE Application Server Cluster into a virtualized environment, many decisions need to be made. I'm not claiming that all of the decisions that I have a made will work well for every environment. In fact, I'm not even claiming that all of the decisions are the best possible for my environment. I'm only claiming that of the small sample of configurations that I've tested, this is the one that is working best for me. Here are some of the decisions that needed to be made: (1.1) Which virtualization option? There are several virtualization options and isolation levels that are available. Options include: Hard partitions: Dynamic Domains on Sun SPARC Enterprise M-Series Servers Hypervisor based virtualization such as Oracle VM Server for SPARC (LDOMs) on SPARC T-Series Servers OS Virtualization using Oracle Solaris Containers Resource management tools in the Oracle Solaris OS to control the amount of resources an application receives, such as CPU cycles, physical memory, and network bandwidth. Oracle Solaris Containers provide the right level of isolation and flexibility for my environment. To borrow some words from my friends in marketing, "The SPARC T4 processor leverages the unique, no-cost virtualization capabilities of Oracle Solaris Zones" (1.2) How to associate Oracle Solaris Containers with resources? There are several options available to associate containers with resources, including (a) resource pool association (b) dedicated-cpu resources and (c) capped-cpu resources. I chose to create resource pools and associate them with the containers because I wanted explicit control over the cores and virtual processors. (1.3) Cluster Topology? Is it best to deploy (a) multiple application servers on one node, (b) one application server on multiple nodes, or (c) multiple application servers on multiple nodes? After a few quick tests, it appears that one application server per Oracle Solaris Container is a good solution. (1.4) Number of cluster members to deploy? I chose to deploy four big 64-bit application servers. I would like go back a test many 32-bit application servers, but that is left for another day. (2.0) Configuration tested. (2.1) I was using a SPARC T4-2 Server which has 2 CPU and 128 virtual processors. To understand the physical layout of the hardware on Solaris 10, I used the OpenSolaris psrinfo perl script available at http://hub.opensolaris.org/bin/download/Community+Group+performance/files/psrinfo.pl: test# ./psrinfo.pl -pv The physical processor has 8 cores and 64 virtual processors (0-63) The core has 8 virtual processors (0-7) The core has 8 virtual processors (8-15) The core has 8 virtual processors (16-23) The core has 8 virtual processors (24-31) The core has 8 virtual processors (32-39) The core has 8 virtual processors (40-47) The core has 8 virtual processors (48-55) The core has 8 virtual processors (56-63) SPARC-T4 (chipid 0, clock 2848 MHz) The physical processor has 8 cores and 64 virtual processors (64-127) The core has 8 virtual processors (64-71) The core has 8 virtual processors (72-79) The core has 8 virtual processors (80-87) The core has 8 virtual processors (88-95) The core has 8 virtual processors (96-103) The core has 8 virtual processors (104-111) The core has 8 virtual processors (112-119) The core has 8 virtual processors (120-127) SPARC-T4 (chipid 1, clock 2848 MHz) (2.2) The "before" test: without processor binding. I started with a 4-member cluster deployed into 4 Oracle Solaris Containers. Each container used a unique gigabit Ethernet port for HTTP traffic. The containers shared a 10 gigabit Ethernet port for JDBC traffic. (2.3) The "after" test: with processor binding. I ran one application server in the Global Zone and another application server in each of the three non-global zones (NGZ): (3.0) Configuration steps. The following steps need to be repeated for all three Oracle Solaris Containers. (3.1) Stop AppServers from the BUI. (3.2) Stop the NGZ. test# ssh test-z2 init 5 (3.3) Enable resource pools: test# svcadm enable pools (3.4) Create the resource pool: test# poolcfg -dc 'create pool pool-test-z2' (3.5) Create the processor set: test# poolcfg -dc 'create pset pset-test-z2' (3.6) Specify the maximum number of CPU's that may be addd to the processor set: test# poolcfg -dc 'modify pset pset-test-z2 (uint pset.max=32)' (3.7) bash syntax to add Virtual CPUs to the processor set: test# (( i = 64 )); while (( i < 96 )); do poolcfg -dc "transfer to pset pset-test-z2 (cpu $i)"; (( i = i + 1 )) ; done (3.8) Associate the resource pool with the processor set: test# poolcfg -dc 'associate pool pool-test-z2 (pset pset-test-z2)' (3.9) Tell the zone to use the resource pool that has been created: test# zonecfg -z test-z1 set pool=pool-test-z2 (3.10) Boot the Oracle Solaris Container test# zoneadm -z test-z2 boot (3.11) Save the configuration to /etc/pooladm.conf test# pooladm -s (4.0) Results. Using the resource pools improves both throughput and response time: (5.0) References: System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones Capitalizing on large numbers of processors with WebSphere Portal on Solaris WebSphere Application Server and T5440 (Dileep Kumar's Weblog) http://www.brendangregg.com/zones.html Reuters Market Data System, RMDS 6 Multiple Instances (Consolidated), Performance Test Results in Solaris, Containers/Zones Environment on Sun Blade X6270 by Amjad Khan, 2009.

Clouds Everywhere But not a Drop of Rain – Part 3

- by sxkumar

I was sharing with you how a broad-based transformation such as cloud will increase agility and efficiency of an organization if process re-engineering is part of the plan. I have also stressed on the key enterprise requirements such as “broad and deep solutions, “running your mission critical applications” and “automated and integrated set of capabilities”. Let me walk you through some key cloud attributes such as “elasticity” and “self-service” and what they mean for an enterprise class cloud. I will also talk about how we at Oracle have taken a very enterprise centric view to developing cloud solutions and how our products have been specifically engineered to address enterprise cloud needs. Cloud Elasticity and Enterprise Applications Requirements Easy and quick scalability for a short-period of time is the signature of cloud based solutions. It is this elasticity that allows you to dynamically redistribute your resources according to business priorities, helps increase your overall resource utilization, and reduces operational costs by allowing you to get the most out of your existing investment. Most public clouds are offering a instant provisioning mechanism of compute power (CPU, RAM, Disk), customer pay for the instance-hours(and bandwidth) they use, adding computing resources at peak times and removing them when they are no longer needed. This type of “just-in-time” serving of compute resources is well known for mid-tiers “state less” servers such as web application servers and web servers that just need another machine to start and run on it but what does it really mean for an enterprise application and its underlying data? Most enterprise applications are not as quite as “state less” and justifiably so. As such, how do you take advantage of cloud elasticity and make it relevant for your enterprise apps? This is where Cloud meets Grid Computing. At Oracle, we have invested enormous amount of time, energy and resources in creating enterprise grid solutions. All our technology products offer built-in elasticity via clustering and dynamic scaling. With products like Real Application Clusters (RAC), Automatic Storage Management, WebLogic Clustering, and Coherence In-Memory Grid, we allow all your enterprise applications to benefit from Cloud elasticity –both vertically and horizontally - without requiring any application changes. A number of technology vendors take a rather simplistic route of starting up additional or removing unneeded VM as the "Cloud Scale-Out" solution. While this may work for stateless mid-tier servers where load balancers can handle the addition and remove of instances transparently but following a similar approach for the database tier - often called as "database sharding" - requires significant application modification and typically does not work with off the shelf packaged applications. Technologies like Oracle Database Real Application Clusters, Automatic Storage Management, etc. on the other hand bring the benefits of incremental scalability and on-demand elasticity to ANY application by providing a simplified abstraction layers where the application does not need deal with data spread over multiple database instances. Rather they just talk to a single database and the database software takes care of aggregating resources across multiple hardware components. It is the technologies like these that truly make a cloud solution relevant for enterprises. For customers who are looking for a next generation hardware consolidation platform, our engineered systems (e.g. Exadata, Exalogic) not only provide incredible amount of performance and capacity, they also reduce the data center complexity and simplify operations. Assemble, Deploy and Manage Enterprise Applications for Cloud Products like Oracle Virtual assembly builder (OVAB) resolve the complex problem of bringing the cloud speed to complex multi-tier applications. With assemblies, you can not only provision all components of a multi-tier application and wire them together by push of a button, other aspects of application lifecycle, such as real-time application testing, scale-up/scale-down, performance and availability monitoring, etc., are also automated using Oracle Enterprise Manager. An essential criteria for an enterprise cloud to succeed is the ability to ensure business service levels especially when business users have either full visibility on the usage cost with a “show back” or a “charge back”. With Oracle Enterprise Manager 12c, we have created the most comprehensive cloud management solution in the industry that is capable of managing business service levels “applications-to-disk” in a enterprise private cloud – all from a single console. It is the only cloud management platform in the industry that allows you to deliver infrastructure, platform and application cloud services out of the box. Moreover, it offers integrated and complete lifecycle management of the cloud - including planning and set up, service delivery, operations management, metering and chargeback, etc . Sounds unbelievable? Well, just watch this space for more details on how Oracle Enterprise Manager 12c is the nerve center of Oracle Cloud! Our cloud solution portfolio is also the broadest and most deep in the industry - covering public, private, hybrid, Infrastructure, platform and applications clouds. It is no coincidence therefore that the Oracle Cloud today offers the most comprehensive set of public cloud services in the industry. And to a large part, this has been made possible thanks to our years on investment in creating cloud enabling technologies. Summary But the intent of this blog post isn't to dwell on how great our solutions are (these are just some examples to illustrate how we at Oracle have approached this problem space). Rather it is to help you ask the right questions before you embark on your cloud journey. So to summarize, here are the key takeaways. It is critical that you are clear on why you are building the cloud. Successful organizations keep business benefits as the first and foremost cloud objective. On the other hand, those who approach this purely as a technology project are more likely to fail. Think about where you want to be in 3-5 years before you get started. Your long terms objectives should determine what your first step ought to be. As obvious as it may seem, more people than not make the first move without knowing where they are headed. Don’t make the mistake of equating cloud to virtualization and Infrastructure-as-a-Service (IaaS). Spinning a VM on-demand will give some short term relief to your IT staff but is unlikely to solve your larger business problems. As such, even if IaaS is your first step towards a more comprehensive cloud, plan the roadmap around those higher level services before you begin. And ask your vendors on how they are going to be your partners in this journey. Capabilities like self-service access and chargeback/showback are absolutely critical if you really expect your cloud to be transformational. Your business won't see the full benefits of the cloud until it empowers them with same kind of control and transparency that they are used to while using a public cloud service. Evaluate the benefits of integration, as opposed to blindly following the best-of-breed strategy. Integration is a huge challenge and more so in a cloud environment. There are enormous costs associated with stitching a solution out of disparate components and even more in maintaining it. Hope you found these ideas helpful. Looking forward to hearing your thoughts and experiences.

7u10: JavaFX packaging tools update

- by igor

Last weeks were very busy here in Oracle. JavaOne 2012 is next week. Come to see us there! Meanwhile i'd like to quickly update you on recent developments in the area of packaging tools. This is an area of ongoing development for the team, and we are continuing to refine and improve both the tools and the process. Thanks to everyone who shared experiences and suggestions with us. We are listening and fixed many of reported issues. Please keep them coming as comments on the blog or (even better) file issues directly to the JIRA. In this post i'll focus on several new packaging features added in JDK 7 update 10: Self-Contained Applications: Select Java Runtime to bundle Self-Contained Applications: Create Package without Java Runtime Self-Contained Applications: Package non-JavaFX application Option to disable proxy setup in the JavaFX launcher Ability to specify codebase for WebStart application Option to update existing jar file Self-Contained Applications: Specify application icon Self-Contained Applications: Pass parameters on the command line All these features and number of other important bug fixes are available in the developer preview builds of JDK 7 update 10 (build 8 or later). Please give them a try and share your feedback! Self-Contained Applications: Select Java Runtime to bundle Packager tools in 7u6 assume current JDK (based on java.home property) is the source for embedded runtime. This is useful simplification for many scenarios but there are cases where ability to specify what to embed explicitly is handy. For example IDE may be using fixed JDK to build the project and this is not the version you want to bundle into your application. To make it more flexible we now allow to specify location of base JDK explicitly. It is optional and if you do not specify it then current JDK will be used (i.e. this change is fully backward compatible). New 'basedir' attribute was added to <fx:platform> tag. Its value is location of JDK to be used. It is ok to point to either JRE inside the JDK or JDK top level folder. However, it must be JDK and not JRE as we need other JDK tools for proper packaging and it must be recent version of JDK that is bundled with JavaFX (i.e. Java 7 update 6 or later). Here are examples (<fx:platform> is part of <fx:deploy> task): <fx:platform basedir="${java.home}"/> <fx:platform basedir="c:\tools\jdk7"/> Hint: this feature enables you to use packaging tools from JDK 7 update 10 (and benefit from bug fixes and other features described below) to create application package with bundled FCS version of JRE 7 update 6. Self-Contained Applications: Create Package without Java Runtime This may sound a bit puzzling at first glance. Package without embedded Java Runtime is not really self-contained and obviously will not help with: Deployment on fresh systems. JRE need to be installed separately (and this step will require admin permissions). Possible compatibility issues due to updates of system runtime. However, these packages are much much smaller in size. If download size matters and you are confident that user have recommended system JRE installed then this may be good option to consider if you want to improve user experience for install and launch. Technically, this is implemented as an extension of previous feature. Pass empty string as value for 'basedir' attribute and this will be treated as request to not bundle Java runtime, e.g. <fx:platform basedir=""/> Self-Contained Applications: Package non-JavaFX application One of popular questions people ask about self-contained applications - can i package my Java application as self-contained application? Absolutely. This is true even for tools shipped with JDK 7 update 6. Simply follow steps for creating package for Swing application with integrated JavaFX content and they will work even if your application does not use JavaFX. What's wrong with it? Well, there are few caveats: bundle size is larger because JavaFX is bundled whilst it is not really needed main application jar needs to be packaged to comply to JavaFX packaging requirements(and this may be not trivial to achieve in your existing build scripts) javafx application launcher may not work well with startup logic of your application (for example launcher will initialize networking stack and this may void custom networking settings in your application code) In JDK 7 update 6 <fx:deploy> was updated to accept arbitrary executable jar as an input. Self-contained application package will be created preserving input jar as-is, i.e. no JavaFX launcher will be embedded. This does not help with first point above but resolves other two. More formally following assertions must be true for packaging to succeed: application can be launched as "java -jar YourApp.jar" from the command line mainClass attribute of <fx:application> refers to application main class <fx:resources> lists all resources needed for the application To give you an example lets assume we need to create a bundle for application consisting of 3 jars: dist/javamain.jar dist/lib/somelib.jar dist/morelibs/anotherlib.jar where javamain.jar has manifest with Main-Class: app.Main Class-Path: lib/somelib.jar morelibs/anotherlib.jar Here is sample ant code to package it: <target name="package-bundle"> <taskdef resource="com/sun/javafx/tools/ant/antlib.xml" uri="javafx:com.sun.javafx.tools.ant" classpath="${javafx.tools.ant.jar}"/> <fx:deploy nativeBundles="all" width="100" height="100" outdir="native-packages/" outfile="MyJavaApp"> <info title="Sample project" vendor="Me" description="Test built from Java executable jar"/> <fx:application id="myapp" version="1.0" mainClass="app.Main" name="MyJavaApp"/> <fx:resources> <fx:fileset dir="dist"> <include name="javamain.jar"/> <include name="lib/somelib.jar"/> <include name="morelibs/anotherlib.jar"/> </fx:fileset> </fx:resources> </fx:deploy> </target> Option to disable proxy setup in the JavaFX launcher Since JavaFX 2.2 (part of JDK 7u6) properly packaged JavaFX applications have proxy settings initialized according to Java Runtime configuration settings. This is handy for most of the application accessing network with one exception. If your application explicitly sets networking properties (e.g. socksProxyHost) then they must be set before networking stack is initialized. Proxy detection will initialize networking stack and therefore your custom settings will be ignored. One way to disable proxy setup by the embedded JavaFX launcher is to pass "-Djavafx.autoproxy.disable=true" on the command line. This is good for troubleshooting (proxy detection may cause significant startup time increases if network is misconfigured) but not really user friendly. Now proxy setup will be disabled if manifest of main application jar has "JavaFX-Feature-Proxy" entry with value "None". Here is simple example of adding this entry using <fx:jar> task: <fx:jar destfile="dist/sampleapp.jar"> <fx:application refid="myapp"/> <fx:resources refid="myresources"/> <fileset dir="build/classes"/> <manifest> <attribute name="JavaFX-Feature-Proxy" value="None"/> </manifest> </fx:jar> Ability to specify codebase for WebStart application JavaFX applications do not need to specify codebase (i.e. absolute location where application code will be deployed) for most of real world deployment scenarios. This is convenient as application does not need to be modified when it is moved from development to deployment environment. However, some developers want to ensure copies of their application JNLP file will redirect to master location. This is where codebase is needed. To avoid need to edit JNLP file manually <fx:deploy> task now accepts optional codebase attribute. If attribute is not specified packager will generate same no-codebase files as before. If codebase value is explicitly specified then generated JNLP files (including JNLP content embedded into web page) will use it. Here is an example: <fx:deploy width="600" height="400" outdir="Samples" codebase="http://localhost/codebaseTest" outfile="TestApp"> .... </fx:deploy> Option to update existing jar file JavaFX packaging procedures are optimized for new application that can use ant or command line javafxpackager utility. This may lead to some redundant steps when you add it to your existing build process. One typical situation is that you might already have a build procedure that produces executable jar file with custom manifest. To properly package it as JavaFX executable jar you would need to unpack it and then use javafxpackager or <fx:jar> to create jar again (and you need to make sure you pass all important details from your custom manifest). We added option to pass jar file as an input to javafxpackager and <fx:jar>. This simplifies integration of JavaFX packaging tools into existing build process as postprocessing step. By the way, we are looking for ways to simplify this further. Please share your suggestions! On the technical side this works as follows. Both <fx:jar> and javafxpackager will attempt to update existing jar file if this is the only input file. Update process will add JavaFX launcher classes and update the jar manifest with JavaFX attributes. Your custom attributes will be preserved. Update could be performed in place or result may be saved to a different file. Main-Class and Class-Path elements (if present) of manifest of input jar file will be used for JavaFX application unless they are explicitly overriden in the packaging command you use. E.g. attribute mainClass of <fx:application> (or -appclass in the javafxpackager case) overrides existing Main-Class in the jar manifest. Note that class specified in the Main-Class attribute could either extend JavaFX Application or provide static main() method. Here are examples of updating jar file using javafxpackager: Create new JavaFX executable jar as a copy of given jar file javafxpackager -createjar -srcdir dist -srcfiles fish_proto.jar -outdir dist -outfile fish.jar Update existing jar file to be JavaFX executable jar and use test.Fish as main application class javafxpackager -createjar -srcdir dist -appclass test.Fish -srcfiles fish.jar -outdir dist -outfile fish.jar And here is example of using <fx:jar> to create new JavaFX executable jar from the existing fish_proto.jar: <fx:jar destfile="dist/fish.jar"> <fileset dir="dist"> <include name="fish_proto.jar"/> </fileset> </fx:jar> Self-Contained Applications: Specify application icon The only way to specify application icon for self-contained application using tools in JDK 7 update 6 is to use drop-in resources. Now this bug is resolved and you can also specify icon using <fx:icon> tag. Here is an example: <fx:deploy ...> <fx:info> <fx:icon href="default.png"/> </fx:info> ... </fx:deploy> Few things to keep in mind: Only default kind of icon is applicable to self-contained applications (as of now) Icon should follow platform specific rules for sizes and image format (e.g. .ico on Windows and .icns on Mac) Self-Contained Applications: Pass parameters on the command line JavaFX applications support two types of application parameters: named and unnamed (see the API for Application.Parameters). Static named parameters can be added to the application package using <fx:param> and unnamed parameters can be added using <fx:argument>. They are applicable to all execution modes including standalone applications. It is also possible to pass parameters to a JavaFX application from a Web page that hosts it, using <fx:htmlParam>. Prior to JavaFX 2.2, this was only supported for embedded applications. Starting from JavaFX 2.2, <fx:htmlParam> is applicable to Web Start applications also. See JavaFX deployment guide for more details on this. However, there was no way to pass dynamic parameters to the self-contained application. This has been improved and now native launchers will delegate parameters from command line to the application code. I.e. to pass parameter to the application you simply need to run it as "myapp.exe somevalue" and then use getParameters().getUnnamed().get(0) to get "somevalue".

Handling HumanTask attachments in Oracle BPM 11g PS4FP+ (II)

- by ccasares

Retrieving uploaded attachments -UCM- As stated in my previous blog entry, Oracle BPM 11g 11.1.1.5.1 (aka PS4FP) introduced a new cool feature whereby you can use Oracle WebCenter Content (previously known as Oracle UCM) as the repository for the human task attached documents. For more information about how to use or enable this feature, have a look here. The attachment scope (either TASK or PROCESS) also applies to UCM-attachments. But even with this other feature, one question might arise when using UCM attachments. How can I get them from within the process? The first answer would be to use the same getTaskAttachmentContents() XPath function already explained in my previous blog entry. In fact, that's the way it should be. But in Oracle BPM 11g 11.1.1.5.1 (PS4FP) and 11.1.1.6.0 (PS5) there's a bug that prevents you to do that. If you invoke such function against a UCM-attachment, you'll get a null content response (bug#13907552). Even if the attachment was correctly uploaded. While this bug gets fixed, next I will show a workaround that lets me to retrieve the UCM-attached documents from within a BPM process. Besides, the sample will show how to interact with WCC API from within a BPM process.Aside note: I suggest you to read my previous blog entry about Human Task attachments where I briefly describe some concepts that are used next, such as the execData/attachment[] structure. Sample Process I will be using the following sample process: A dummy UserTask using "HumanTask2" Human Task, followed by an Embedded Subprocess that will retrieve the attachments payload. In this case, and here's the key point of the sample, we will retrieve such payload using WebCenter Content WebService API (IDC): and once retrieved, we will write each of them back to a file in the server using a File Adapter service: In detail: We will use the same attachmentCollection XSD structure and same BusinessObject definition as in the previous blog entry. However we create a separate variable, named attachmentUCM, based on such BusinessObject. We will still need to keep a copy of the HumanTask output's execData structure. Therefore we need to create a new variable of type TaskExecutionData (different one than the other used for non-UCM attachments): As in the non-UCM attachments flow, in the output tab of the UserTask mapping, we'll keep a copy of the execData structure: Now we get into the embedded subprocess that will retrieve the attachments' payload. First, and using an XSLT transformation, we feed the attachmentUCM variable with the following information: The name of each attachment (from execData/attachment/name element) The WebCenter Content ID of the uploaded attachment. This info is stored in execData/attachment/URI element with the format ecm://<id>. As we just want the numeric <id>, we need to get rid of the protocol prefix ("ecm://"). We do so with some XPath functions as detailed below: with these two functions being invoked, respectively: We, again, set the target payload element with an empty string, to get the <payload></payload> tag created. The complete XSLT transformation is shown below. Remember that we're using the XSLT for-each node to create as many target structures as necessary. Once we have fed the attachmentsUCM structure and so it now contains the name of each of the attachments along with each WCC unique id (dID), it is time to iterate through it and get the payload. Therefore we will use a new embedded subprocess of type MultiInstance, that will iterate over the attachmentsUCM/attachment[] element: In each iteration we will use a Service activity that invokes WCC API through a WebService. Follow these steps to create and configure the Partner Link needed: Login to WCC console with an administrator user (i.e. weblogic). Go to Administration menu and click on "Soap Wsdls" link. We will use the GetFile service to retrieve a file based on its dID. Thus we'll need such service WSDL definition that can be downloaded by clicking the GetFile link. Save the WSDL file in your JDev project folder. In the BPM project's composite view, drag & drop a WebService adapter to create a new External Reference, based on the just added GetFile.wsdl. Name it UCM_GetFile. WCC services are secured through basic HTTP authentication. Therefore we need to enable the just created reference for that: Right-click the reference and click on Configure WS Policies. Under the Security section, click "+" to add the "oracle/wss_username_token_client_policy" policy The last step is to set the credentials for the security policy. For the sample we will use the admin user for WCC (weblogic/welcome1). Open the composite.xml file and select the Source view. Search for the UCM_GetFile entry and add the following highlighted elements into it: <reference name="UCM_GetFile" ui:wsdlLocation="GetFile.wsdl"> <interface.wsdl interface="http://www.stellent.com/GetFile/#wsdl.interface(GetFileSoap)"/> <binding.ws port="http://www.stellent.com/GetFile/#wsdl.endpoint(GetFile/GetFileSoap)" location="GetFile.wsdl" soapVersion="1.1"> <wsp:PolicyReference URI="oracle/wss_username_token_client_policy" orawsp:category="security" orawsp:status="enabled"/> <property name="weblogic.wsee.wsat.transaction.flowOption" type="xs:string" many="false">WSDLDriven</property> <property name="oracle.webservices.auth.username" type="xs:string">weblogic</property> <property name="oracle.webservices.auth.password" type="xs:string">welcome1</property> </binding.ws> </reference> Now the new external reference is ready: Once the reference has just been created, we should be able now to use it from our BPM process. However we find here a problem. The WCC GetFile service operation that we will use, GetFileByID, accepts as input a structure similar to this one, where all element tags are optional: <get:GetFileByID xmlns:get="http://www.stellent.com/GetFile/"> <get:dID>?</get:dID> <get:rendition>?</get:rendition> <get:extraProps> <get:property> <get:name>?</get:name> <get:value>?</get:value> </get:property> </get:extraProps></get:GetFileByID> and we need to fill up just the <get:dID> tag element. Due to some kind of restriction or bug on WCC, the rest of the tag elements must NOT be sent, not even empty (i.e.: <get:rendition></get:rendition> or <get:rendition/>). A sample request that performs the query just by the dID, must be in the following format: <get:GetFileByID xmlns:get="http://www.stellent.com/GetFile/"> <get:dID>12345</get:dID></get:GetFileByID> The issue here is that the simple mapping in BPM does create empty tags being a sample result as follows: <get:GetFileByID xmlns:get="http://www.stellent.com/GetFile/"> <get:dID>12345</get:dID> <get:rendition/> <get:extraProps/> </get:GetFileByID> Although the above structure is perfectly valid, it is not accepted by WCC. Therefore, we need to bypass the problem. The workaround we use (many others are available) is to add a Mediator component between the BPM process and the Service that simply copies the input structure from BPM but getting rid of the empty tags. Follow these steps to configure the Mediator: Drag & drop a new Mediator component into the composite. Uncheck the creation of the SOAP bindings and use the Interface Definition from WSDL template and select the existing GetFile.wsdl Double click in the mediator to edit it. Add a static routing rule to the GetFileByID operation, of type Service and select References/UCM_GetFile/GetFileByID target service: Create the request and reply XSLT mappers: Make sure you map only the dID element in the request: And do an Auto-mapper for the whole response: Finally, we can now add and configure the Service activity in the BPM process. Drag & drop it to the embedded subprocess and select the NormalizedGetFile service and getFileByID operation: Map both the input: ...and the output: Once this embedded subprocess ends, we will have all attachments (name + payload) in the attachmentsUCM variable, which is the main goal of this sample. But in order to test everything runs fine, we finish the sample writing each attachment to a file. To that end we include a final embedded subprocess to concurrently iterate through each attachmentsUCM/attachment[] element: On each iteration we will use a Service activity that invokes a File Adapter write service. In here we have two important parameters to set. First, the payload itself. The file adapter awaits binary data in base64 format (string). We have to map it using XPath (Simple mapping doesn't recognize a String as a base64-binary valid target): Second, we must set the target filename using the Service Properties dialog box: Again, note how we're making use of the loopCounter index variable to get the right element within the embedded subprocess iteration. Final blog entry about attachments will handle how to inject documents to Human Tasks from the BPM process and how to share attachments between different User Tasks. Will come soon. Again, once I finish will all posts on this matter, I will upload the whole sample project to java.net.

EM12c: Using the LIST verb in emcli

- by SubinDaniVarughese

Many of us who use EM CLI to write scripts and automate our daily tasks should not miss out on the new list verb released with Oracle Enterprise Manager 12.1.0.3.0. The combination of list and Jython based scripting support in EM CLI makes it easier to achieve automation for complex tasks with just a few lines of code. Before I jump into a script, let me highlight the key attributes of the list verb and why it’s simply excellent! 1. Multiple resources under a single verb:A resource can be set of users or targets, etc. Using the list verb, you can retrieve information about a resource from the repository database.Here is an example which retrieves the list of administrators within EM.Standard mode$ emcli list -resource="Administrators" Interactive modeemcli>list(resource="Administrators")The output will be the same as standard mode.Standard mode$ emcli @myAdmin.pyEnter password : ******The output will be the same as standard mode.Contents of myAdmin.py scriptlogin()print list(resource="Administrators",jsonout=False).out()To get a list of all available resources use$ emcli list -helpWith every release of EM, more resources are being added to the list verb. If you have a resource which you feel would be valuable then go ahead and contact Oracle Support to log an enhancement request with product development. Be sure to say how the resource is going to help improve your daily tasks. 2. Consistent Formatting:It is possible to format the output of any resource consistently using these options: –column This option is used to specify which columns should be shown in the output. Here is an example which shows the list of administrators and their account status$ emcli list -resource="Administrators" -columns="USER_NAME,REPOS_ACCOUNT_STATUS" To get a list of columns in a resource use:$ emcli list -resource="Administrators" -help You can also specify the width of the each column. For example, here the column width of user_type is set to 20 and department to 30. $ emcli list -resource=Administrators -columns="USER_NAME,USER_TYPE:20,COST_CENTER,CONTACT,DEPARTMENT:30"This is useful if your terminal is too small or you need to fine tune a list of specific columns for your quick use or improved readability. –colsize This option is used to resize column widths.Here is the same example as above, but using -colsize to define the width of user_type to 20 and department to 30.$ emcli list -resource=Administrators -columns="USER_NAME,USER_TYPE,COST_CENTER,CONTACT,DEPARTMENT" -colsize="USER_TYPE:20,DEPARTMENT:30" The existing standard EMCLI formatting options are also available in list verb. They are: -format="name:pretty" | -format="name:script” | -format="name:csv" | -noheader | -scriptThere are so many uses depending on your needs. Have a look at the resources and columns in each resource. Refer to the EMCLI book in EM documentation for more information.3. Search:Using the -search option in the list verb makes it is possible to search for a specific row in a specific column within a resource. This is similar to the sqlplus where clause. The following operators are supported: = != > < >= <= like is (Must be followed by null or not null)Here is an example which searches for all EM administrators in the marketing department located in the USA.$emcli list -resource="Administrators" -search="DEPARTMENT ='Marketing'" -search="LOCATION='USA'" Here is another example which shows all the named credentials created since a specific date. $emcli list -resource=NamedCredentials -search="CredCreatedDate > '11-Nov-2013 12:37:20 PM'"Note that the timestamp has to be in the format DD-MON-YYYY HH:MI:SS AM/PM Some resources need a bind variable to be passed to get output. A bind variable is created in the resource and then referenced in the command. For example, this command will list all the default preferred credentials for target type oracle_database.Here is an example$ emcli list -resource="PreferredCredentialsDefault" -bind="TargetType='oracle_database'" -colsize="SetName:15,TargetType:15" You can provide multiple bind variables. To verify if a column is searchable or requires a bind variable, use the –help option. Here is an example:$ emcli list -resource="PreferredCredentialsDefault" -help 4. Secure accessWhen list verb collects the data, it only displays content for which the administrator currently logged into emcli, has access. For example consider this usecase:AdminA has access only to TargetA. AdminA logs into EM CLIExecuting the list verb to get the list of all targets will only show TargetA.5. User defined SQLUsing the –sql option, user defined sql can be executed. The SQL provided in the -sql option is executed as the EM user MGMT_VIEW, which has read-only access to the EM published MGMT$ database views in the SYSMAN schema. To get the list of EM published MGMT$ database views, go to the Extensibility Programmer's Reference book in EM documentation. There is a chapter about Using Management Repository Views. It’s always recommended to reference the documentation for the supported MGMT$ database views. Consider you are using the MGMT$ABC view which is not in the chapter. During upgrade, it is possible, since the view was not in the book and not supported, it is likely the view might undergo a change in its structure or the data in it. Using a supported view ensures that your scripts using -sql will continue working after upgrade.Here’s an example $ emcli list -sql='select * from mgmt$target' 6. JSON output support JSON (JavaScript Object Notation) enables data to be displayed in a collection of name/value pairs. There is lot of reading material about JSON on line for more information.As an example, we had a requirement where an EM administrator had many 11.2 databases in their test environment and the developers had requested an Administrator to change the lifecycle status from Test to Production which meant the admin had to go to the EM “All targets” page and identify the set of 11.2 databases and then to go into each target database page and manually changes the property to Production. Sounds easy to say, but this Administrator had numerous targets and this task is repeated for every release cycle.We told him there is an easier way to do this with a script and he can reuse the script whenever anyone wanted to change a set of targets to a different Lifecycle status. Here is a jython script which uses list and JSON to change all 11.2 database target’s LifeCycle Property value.If you are new to scripting and Jython, I would suggest visiting the basic chapters in any Jython tutorials. Understanding Jython is important to write the logic depending on your usecase.If you are already writing scripts like perl or shell or know a programming language like java, then you can easily understand the logic.Disclaimer: The scripts in this post are subject to the Oracle Terms of Use located here. 1 from emcli import * 2 search_list = ['PROPERTY_NAME=\'DBVersion\'','TARGET_TYPE= \'oracle_database\'','PROPERTY_VALUE LIKE \'11.2%\''] 3 if len(sys.argv) == 2: 4 print login(username=sys.argv[0]) 5 l_prop_val_to_set = sys.argv[1] 6 l_targets = list(resource="TargetProperties", search=search_list, columns="TARGET_NAME,TARGET_TYPE,PROPERTY_NAME") 7 for target in l_targets.out()['data']: 8 t_pn = 'LifeCycle Status' 9 print "INFO: Setting Property name " + t_pn + " to value " + l_prop_val_to_set + " for " + target['TARGET_NAME'] 10 print set_target_property_value(property_records= target['TARGET_NAME']+":"+target['TARGET_TYPE']+":"+ t_pn+":"+l_prop_val_to_set) 11 else: 12 print "\n ERROR: Property value argument is missing" 13 print "\n INFO: Format to run this file is filename.py <username> <Database Target LifeCycle Status Property Value>" You can download the script from here. I could not upload the file with .py extension so you need to rename the file to myScript.py before executing it using emcli.A line by line explanation for beginners: Line 1 Imports the emcli verbs as functions 2 search_list is a variable to pass to the search option in list verb. I am using escape character for the single quotes. In list verb to pass more than one value for the same option, you should define as above comma separated values, surrounded by square brackets. 3 This is an “if” condition to ensure the user does provide two arguments with the script, else in line #15, it prints an error message. 4 Logging into EM. You can remove this if you have setup emcli with autologin. For more details about setup and autologin, please go the EM CLI book in EM documentation. 5 l_prop_val_to_set is another variable. This is the property value to be set. Remember we are changing the value from Test to Production. The benefit of this variable is you can reuse the script to change the property value from and to any other values. 6 Here the output of the list verb is stored in l_targets. In the list verb I am passing the resource as TargetProperties, search as the search_list variable and I only need these three columns – target_name, target_type and property_name. I don’t need the other columns for my task. 7 This is a for loop. The data in l_targets is available in JSON format. Using the for loop, each pair will now be available in the ‘target’ variable. 8 t_pn is the “LifeCycle Status” variable. If required, I can have this also as an input and then use my script to change any target property. In this example, I just wanted to change the “LifeCycle Status”. 9 This a message informing the user the script is setting the property value for dbxyz. 10 This line shows the set_target_property_value verb which sets the value using the property_records option. Once it is set for a target pair, it moves to the next one. In my example, I am just showing three dbs, but the real use is when you have 20 or 50 targets. The script is executed as:$ emcli @myScript.py subin Production The recommendation is to first test the scripts before running it on a production system. We tested on a small set of targets and optimizing the script for fewer lines of code and better messaging.For your quick reference, the resources available in Enterprise Manager 12.1.0.4.0 with list verb are:$ emcli list -helpWatch this space for more blog posts using the list verb and EM CLI Scripting use cases.
