  • Upgrade 10g Osso to 11g OAM (Part 2)

    - by Pankaj Chandiramani
    This is part 2 of http://blogs.oracle.com/pankaj/2010/11/upgrade_10g_osso_to_11g_oam.html So last post we saw the overview of upgrading osso to oam11g . Now some more details on same . As we are using the co-existence feature , we have to install the OAM server and upgrade the existing OSSO 10g server to the OAM servers. OAM Upgrade Steps Overview Pre-Req : You already have a OAM 11g Installed Upgrade Step 1: Configure User Store & Make it Primary Upgrade Step 2: Create Policy Domain , this is dome by UA automatically Upgrade Step 3: Migrate Partners : This is done by running Upgrade Assistant Verify successful Upgrade Details on UA step : To Upgrade the existing OSSO 10g servers to OAM server , this is done by running the UA script in OAM , which copies over all the partner app details from osso to OAM 11g , run_ua.sh is the script name which will ask you to input the Policies.properties from SSO $OH/sso/config folder of osso 10g & other variables like db password . Some pointers Upgrading oso to Oam 11g , by default enables the coexistence mode on the OAM Server Front-end the OAM server with the same Load Balancer that is the front end of the OSSO 10g servers. Now, OAM and OSSO 10g servers are working in a co-exist mode. OAM 11g is made to understand 10g OSSO Token format and session handling capabilities so as to co-exist with 10g OSSO servers./li How to test ? Try to access the partner applications and verify that single sign on works. Also, verify that user does not have to login in if the user is already authenticated by either OAM or OSSO 10g server. Screen-shots & Troubleshooting tips to be followed .......

  • SQL SERVER – Detecting guest User Permissions – guest User Access Status

    - by pinaldave
    Earlier I wrote the blog post SQL SERVER – Disable Guest Account – Serious Security Issue, and I got many comments asking questions related to the guest user. Here are the comments of Manoj: 1) How do we know if the uest user is enabled or disabled? 2) What is the default for guest user in SQL Server? Default settings for guest user When SQL Server is installed by default, the guest user is disabled for security reasons. If the guest user is not properly configured, it can create a major security issue. You can read more about this here. Identify guest user status There are multiple ways to identify guest user status: Using SQL Server Management Studio (SSMS) You can expand the database node >> Security >> Users. If you see the RED arrow pointing downward, it means that the guest user is disabled. Using sys.sysusers Here is a simple script. If you notice column dbaccess as 1, it means that the guest user is enabled and has access to the database. SELECT name, hasdbaccess FROM sys.sysusers WHERE name = 'guest' Using sys.database_principals and sys.server_permissions This script is valid in SQL Server 2005 and a later version. This is my default method recently. SELECT name, permission_name, state_desc FROM sys.database_principals dp INNER JOIN sys.server_permissions sp ON dp.principal_id = sp.grantee_principal_id WHERE name = 'guest' AND permission_name = 'CONNECT' Using sp_helprotect Just run the following stored procedure which will give you all the permissions associated with the user. sp_helprotect @username = 'guest' Disable Guest Account REVOKE CONNECT FROM guest Additionally, the guest account cannot be disabled in master and tempdb; it is always enabled. There is a special need for this. Let me ask a question back at you: In which scenario do you think this will be useful to keep the guest, and what will the additional configuration go along with the scenario? Note: Special mention to Imran Mohammed for being always there when users need help.

  • Access to Salesforce.com Data Through Tableau Desktop

    - by dataintegration
    This article will explain how to connect to any of the RSSBus OData Connectors with Tableau's business intelligence tool. While the example uses the Salesforce Connector, the same process can be followed for any of the OData Connectors. Step 1: Download and install both the Salesforce Connector from RSSBus and Tableau Desktop from Tableau. Step 2: Next you will want to configure the Salesforce Connector to connect with your Salesforce.com account. If you browse to the Help tab in the Salesforce Connector application, there is a link to the Getting Started Guide which will walk you through setting up the Salesforce Connector. Step 3: Once you have successfully configured the Salesforce Connector application, you will want to open Tableau and select the Connect to data option at the top left of the window. Step 4: Here you will click on the option labeled OData under the section labeled On a server. Step 5: A new pop up will appear. The box under Step 1 of the pop-up must contain the OData URL of the Salesforce Connector table. You can find this by clicking on the Settings tab of the Salesforce Connector. Once you have found the OData entry URL, you will need to append the table name that you want Tableau to connect with to the OData entry URL. In this example, we will connect to the Account table. Thus, the URL we enter will be: http://localhost:8181/sfconnector/data/conn/odata.rsc/Account. You will also need to add authentication options in this step. To do this, select the Use a Username and Password option in Step 2 of the pop-up and enter the Username and Password of the user who has access to the Salesforce Connector. When you are done, click the Connect button in Step 3 of the pop-up. Step 6: When the connection to the Salesforce Connector is successful, give the connection a name and click the OK button. Step 7: The table columns will be listed on the left side under the Dimensions section of the workspace. Step 8: To view your Salesforce.com data, you can right click under the table name in the Data section at the top left of the dashboard and select the View Data option. Your Saleforce.com data will appear in Tableau.

  • High load average, low CPU and IO (Centos 5.7)

    - by Ben
    A Drupal 7 site with CiviCRM, after running smoothly for a year on a 1&1 VPS suddenly became unresponsive. Now pages eventually load, but can take more than a minute. Looking at resource use in Virtuozzo, the load average carries a warning, and has remained above 1. While I understand this isn't particularly high, this is a change from when the site was working. Here is a typical snapshot of top: top - 03:10:32 up 3:21, 1 user, load average: 1.16, 1.22, 1.30 Tasks: 43 total, 1 running, 42 sleeping, 0 stopped, 0 zombie Cpu(s): 0.1%us, 0.1%sy, 0.1%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 2097152k total, 1015112k used, 1082040k free, 0k buffers Swap: 0k total, 0k used, 0k free, 0k cached CPU idle level never seems to go much below 70%. wa is virtually always at 0. There appears to be lots of free memory. And here is some vmstat output, again showign wa at 0, plenty of free memory, and an idle CPU: procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 2 0 0 1100872 0 0 0 0 2783 23672 0 538 1 0 99 0 0 1 0 0 1100872 0 0 0 0 0 16 0 101754 0 0 100 0 0 0 0 0 1100872 0 0 0 0 0 17 0 103133 0 0 100 0 0 0 0 0 1100872 0 0 0 0 0 1 0 102080 0 0 100 0 0 1 0 0 1100872 0 0 0 0 0 6 0 99881 0 0 100 0 0 0 0 0 1100872 0 0 0 0 0 1 0 105187 0 0 100 0 0 I've spoken to 1&1 but they don't have any ideas as to what could be causing the high load average. Instead they suggested an upgrade :) I've looked for processes that might be causing this, examined MySQL showprocesslist, and restarted the container with no result. Does anyone have more troubleshooting suggestions or insights?

  • PHP displays blank white page even with all error reporting enabled

    - by Andy Shinn
    I am trying to debug a broken page in a Drupal application and am having a hard time getting PHP to spit anything useful out. I have the following set: error_reporting = E_ALL display_errors = On display_startup_errors = On log_errors = On error_log = /var/log/php/php_error.log I have a file showing me phpinfo() which confirms these variables are set correctly for the environment. I have increased memory_limit to 256M (which should be more than enough). Yet, the only indication I get is a status 500 code in the apache access log and a blank white page from PHP. The Apache virtual host has LogLevel set to debug and the error log only outputs: [Sat Jun 16 20:03:03 2012] [debug] mod_deflate.c(615): [client 173.8.175.217] Zlib: Compressed 0 to 2 : URL /index.php, referer: http://ec2-174-129-192-237.compute-1.amazonaws.com/admin/reports/updates [Sat Jun 16 20:03:03 2012] [error] [client 173.8.175.217] File does not exist: /var/www/favicon.ico [Sat Jun 16 20:03:03 2012] [debug] mod_deflate.c(615): [client 173.8.175.217] Zlib: Compressed 42 to 44 : URL /favicon.ico The PHP error log outputs nothing at all. kernel and syslog show nothing related to Apache or PHP. I have also tried installing suphp and checking its log just confirms the user is executing correctly: [Sat Jun 16 20:02:59 2012] [info] Executing "/var/www/index.php" as UID 1000, GID 1000 [Sat Jun 16 20:05:03 2012] [info] Executing "/var/www/index.php" as UID 1000, GID 1000 This is on Ubuntu 12.04 x86_64 with the following PHP modules: ii php5 5.3.10-1ubuntu3.1 server-side, HTML-embedded scripting language (metapackage) ii php5-cgi 5.3.10-1ubuntu3.1 server-side, HTML-embedded scripting language (CGI binary) ii php5-cli 5.3.10-1ubuntu3.1 command-line interpreter for the php5 scripting language ii php5-common 5.3.10-1ubuntu3.1 Common files for packages built from the php5 source ii php5-curl 5.3.10-1ubuntu3.1 CURL module for php5 ii php5-gd 5.3.10-1ubuntu3.1 GD module for php5 ii php5-mysql 5.3.10-1ubuntu3.1 MySQL module for php5 So, what am I missing here? Why no error reporting?

  • How can use mod_rewrite to redirect a multiple specific URLs containing multiple query strings?

    - by Derek
    Hi there folks, we recently migrated a site from a custom CMS to drupal. In an effort to preserve some links that our users bookmarked (we have about 120 redirects) we would like to forward the original URLs to a new URL. I have been searching for a couple days, but can't seem to find anything simple to what I need. We have existing URLS that contain one or more query strings, for example: /article.php?issue_id=12&article_id=275 and we would like to forward to the new location: http://foobar.edu/content/super-happy-fun-article I started using: RewriteEngine On RewriteRule ^/article\.php?issue_id=12&article_id=275$ http://foobar.edu/content/super-happy-fun-article [R=301,L] This, however, does not work. A simple RewriteRule works: RewriteRule ^test\.php$ index.php It is unclear to me how I need to use {QUERY_STRING} with multiple Basically it's 120 simple redirects that go from one existing URL to a new one. I don't need ranges [0-9], because there is no sequential order to existing URLs. Perhaps I can do what I need with RewriteMap and a simple text file that contains a line like this: index.php?issue_id=12&articleType_section=0&articleType_id=65 http://foobar.edu/category/fall-2008 If anyone has any idea on using mod_rewrite to accomplish this or if there is a better, or more simple mod, I am open to that as well. Thanks!

  • Access Master Page Controls II

    - by Bunch
    Here is another way to access master page controls. This way has a bit less coding then my previous post on the subject. The scenario would be that you have a master page with a few navigation buttons at the top for users to navigate the app. After a button is clicked the corresponding aspx page would load in the ContentPlaceHolder. To make it easier for the users to see what page they are on I wanted the clicked navigation button to change color. This would be a quick visual for the user and is useful when inevitably they are interrupted with something else and cannot get back to what they were doing for a little while. Anyway the code is something like this. Master page: <body>     <form id="form1" runat="server">     <div id="header">     <asp:Panel ID="Panel1" runat="server" CssClass="panelHeader" Width="100%">        <center>            <label style="font-size: large; color: White;">Test Application</label>        </center>       <asp:Button ID="btnPage1" runat="server" Text="Page1" PostBackUrl="~/Page1.aspx" CssClass="navButton"/>       <asp:Button ID="btnPage2" runat="server" Text="Page2" PostBackUrl="~/Page2.aspx" CssClass="navButton"/>       <br />     </asp:Panel>     <br />     </div>     <div>         <asp:scriptmanager ID="Scriptmanager1" runat="server"></asp:scriptmanager>         <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">         </asp:ContentPlaceHolder>     </div>     </form> </body> Page 1: VB Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load     Dim clickedButton As Button = Master.FindControl("btnPage1")     clickedButton.CssClass = "navButtonClicked" End Sub CSharp protected void Page_Load(object sender, EventArgs e) {     Button clickedButton;     clickedButton = (Button)Master.FindControl("btnPage1");     clickedButton.CssClass = "navButtonClicked"; } CSS: .navButton {     background-color: White;     border: 1px #4e667d solid;     color: #2275a7;     display: inline;     line-height: 1.35em;     text-decoration: none;     white-space: nowrap;     width: 100px;     text-align: center;     margin-bottom: 10px;     margin-left: 5px;     height: 30px; } .navButtonClicked {     background-color:#FFFF86;     border: 1px #4e667d solid;     color: #2275a7;     display: inline;     line-height: 1.35em;     text-decoration: none;     white-space: nowrap;     width: 100px;     text-align: center;     margin-bottom: 10px;     margin-left: 5px;     height: 30px; } The idea is pretty simple, use FindControl for the master page in the page load of your aspx page. In the example I changed the CssClass for the aspx page's corresponding button to navButtonClicked which has a different background-color and makes the clicked button stand out.

  • Asp.Net Login Control very slow initial connection to Non-Trusted AD Domain

    - by Eric Brown - Cal
    ASP.NET Login control is very slow making the initial connection to AD when authenticating to a different domain than the domain the web server is a member of. Problem occurs for the IIS server and when using with the Visual Studio's built in web server. It takes about 30 seconds the first time when attempting to use the control to connect against another domain. There is no trust relationship bewteen the web server's domain and the other domains (attempted connecting to several different domains). Subsequent connections execute quickly until the connection times out. Using Systernals Process Monitor to troubleshoot, there are two OpenQuery operations right before the delay to "C:\WINDOWS\asembly\GAC_MSIL\System.DirectoryServices\2.0.0.0_b03f5f7f11d50a3a\Netapi32.dll with a result NAME NOT FOUND" and right after the 30 second delay the TCP Send and TCP Recieves indicate communication begins with the AD server. Things we have tried: Impersonating an administrator on the web server in the web.config; Granting permissions to the CryptoKeys to the NetworkService and ASPNET; Specifying by IP instead of DNS name; Multiple variations of specifying the name and ldap server with domains and OU's; Local host entries; Looked for ports being blocked (SYN_SENT) with netstat -an. Nslookup resolves all the domains and systems involved correectly. TraceRt shows the Correct routes Any Idea or hints are greately appreicated.

  • Single Responsibility Principle vs Anemic Domain Model anti-pattern

    - by Niall Connaughton
    I'm in a project that takes the Single Responsibility Principle pretty seriously. We have a lot of small classes and things are quite simple. However, we have an anemic domain model - there is no behaviour in any of our model classes, they are just property bags. This isn't a complaint about our design - it actually seems to work quite well During design reviews, SRP is brought out whenever new behaviour is added to the system, and so new behaviour typically ends up in a new class. This keeps things very easily unit testable, but I am perplexed sometimes because it feels like pulling behaviour out of the place where it's relevant. I'm trying to improve my understanding of how to apply SRP properly. It seems to me that SRP is in opposition to adding business modelling behaviour that shares the same context to one object, because the object inevitably ends up either doing more than one related thing, or doing one thing but knowing multiple business rules that change the shape of its outputs. If that is so, then it feels like the end result is an Anemic Domain Model, which is certainly the case in our project. Yet the Anemic Domain Model is an anti-pattern. Can these two ideas coexist? EDIT: A couple of context related links: SRP - http://www.objectmentor.com/resources/articles/srp.pdf Anemic Domain Model - http://martinfowler.com/bliki/AnemicDomainModel.html I'm not the kind of developer who just likes to find a prophet and follow what they say as gospel. So I don't provide links to these as a way of stating "these are the rules", just as a source of definition of the two concepts.

  • Domain model: should things like Logging, Audit, Persistence be in it

    - by hom.tanks
    I'm having a hard time convincing our architect that a Domain model should only have the essential elements of the business domain on it. Things like the fact that a class is persistable, that it needs logging and auditing and that it has a RESTful URI should not drive the domain model. They can be added later on, by using interfaces. Ours is a healthcare information management system. At the very coarse level, its a system where users login and access their healthcare information. They can share this information with others and be custodian for others' information (think Roles). But because of a few sound bytes that caught on early like "Everything should be a REST resource" the model now has a top level class called Resource that every other class extends from. I'm trying to make him see that the domain model should have well defined concepts like User Account, HealthDocument, UserRole etc which are distinct entities of the business , with specific associations between them. Clubbing everything under Resource class lets our model be inflexible besides being potentially incorrect. But he wants me to show him why its a bad idea to do it his way. I don't know how to articulate that properly but all my OO instincts tell me that its just not right. Any thoughts?

  • Setting up a domain using WAMP and NameCheap's DNS service

    - by Mike Jones
    So, I've been working on this for far longer than I should be and I'm quite thoroughly perplexed and lost. I apologize if this turns out to be a facile question, but I'm entirely befuddled and very much in need of some guidance. Earlier today I registered a cheap .info domain on NameCheap just to play around with as I learn webdev. I have WAMP installed on my computer and I've been testing my projects through localhost. I thought it would be a good idea to have a domain at my disposal in order to understand how it works and better test my work. NameCheap has a complimentary DNS service (not that I entirely understand what DNS is, although I tried), so I'm using that. I direct both the "@" and "www" host names to my IP address, as shown in the below tutorial: https://www.namecheap.com/support/knowledgebase/article.aspx/319/78/how-can-i-setup-an-a-address-record-for-my-domain However, now when I go to the URL of the domain I bought, it confronts me with a login box that seems to be coming from my wifi network. How do I set this up so that it hosts the information in my WAMP server? Thanks in advance for any help, I really appreciate it. And, as a side-note, what should read (print or online) to better understand the structure of the internet? I've been studying HTML/CSS/Javascript, but I'm not sure where to look for pragmatic and comprehensive information on how the internet works and how to utilize it as a website administrator. Thanks so much.

  • teamviewer in "client only" mode

    - by Tommy
    I have a remote PC with the teamviewer on it. I want to use my local teamviewer installation only for connecting to that remote PC, and I don't want any services (teamviewerd) running on my local Ubuntu 14.04. I've tried to disable the service by doing sudo teamviewer --daemon disable but after that I'm not able to connect to the remote PC, because teamviewer reports an error "The Teamviewer daemon is not running!" on start, and I'm not able to access the gui. Is there a way to connect to the remote PC with teamviewer with no teamviewerd running?

  • Using Windows Previous Versions to access ZFS Snapshots (July 14, 2009)

    - by user12612012
    The Previous Versions tab on the Windows desktop provides a straightforward, intuitive way for users to view or recover files from ZFS snapshots.  ZFS snapshots are read-only, point-in-time instances of a ZFS dataset, based on the same copy-on-write transactional model used throughout ZFS.  ZFS snapshots can be used to recover deleted files or previous versions of files and they are space efficient because unchanged data is shared between the file system and its snapshots.  Snapshots are available locally via the .zfs/snapshot directory and remotely via Previous Versions on the Windows desktop. Shadow Copies for Shared Folders was introduced with Windows Server 2003 but subsequently renamed to Previous Versions with the release of Windows Vista and Windows Server 2008.  Windows shadow copies, or snapshots, are based on the Volume Snapshot Service (VSS) and, as the [Shared Folders part of the] name implies, are accessible to clients via SMB shares, which is good news when using the Solaris CIFS Service.  And the nice thing is that no additional configuration is required - it "just works". On Windows clients, snapshots are accessible via the Previous Versions tab in Windows Explorer using the Shadow Copy client, which is available by default on Windows XP SP2 and later.  For Windows 2000 and pre-SP2 Windows XP, the client software is available for download from Microsoft: Shadow Copies for Shared Folders Client. Assuming that we already have a shared ZFS dataset, we can create ZFS snapshots and view them from a Windows client. zfs snapshot tank/home/administrator@snap101zfs snapshot tank/home/administrator@snap102 To view the snapshots on Windows, map the dataset on the client then right click on a folder or file and select Previous Versions.  Note that Windows will only display previous versions of objects that differ from the originals.  So you may have to modify files after creating a snapshot in order to see previous versions of those files. The screenshot above shows various snapshots in the Previous Versions window, created at different times.  On the left panel, the .zfs folder is visible, illustrating that this is a ZFS share.  The .zfs setting can be toggled as desired, it makes no difference when using previous versions.  To make the .zfs folder visible: zfs set snapdir=visible tank/home/administrator To hide the .zfs folder: zfs set snapdir=hidden tank/home/administrator The following screenshot shows the Previous Versions panel when a file has been selected.  In this case the user is prompted to view, copy or restore the file from one of the available snapshots. As can be seen from the screenshots above, the Previous Versions window doesn't display snapshot names: snapshots are listed by snapshot creation time, sorted in time order from most recent to oldest.  There's nothing we can do about this, it's the way that the interface works.  Perhaps one point of note, to avoid confusion, is that the ZFS snapshot creation time isnot the same as the root directory creation timestamp. In ZFS, all object attributes in the original dataset are preserved when a snapshot is taken, including the creation time of the root directory.  Thus the root directory creation timestamp is the time that the directory was created in the original dataset. # ls -d% all /home/administrator         timestamp: atime         Mar 19 15:40:23 2009         timestamp: ctime         Mar 19 15:40:58 2009         timestamp: mtime         Mar 19 15:40:58 2009         timestamp: crtime         Mar 19 15:18:34 2009 # ls -d% all /home/administrator/.zfs/snapshot/snap101         timestamp: atime         Mar 19 15:40:23 2009         timestamp: ctime         Mar 19 15:40:58 2009         timestamp: mtime         Mar 19 15:40:58 2009         timestamp: crtime         Mar 19 15:18:34 2009 The snapshot creation time can be obtained using the zfs command as shown below. # zfs get all tank/home/administrator@snap101NAME                             PROPERTY  VALUEtank/home/administrator@snap101  type      snapshottank/home/administrator@snap101  creation  Mon Mar 23 18:21 2009 In this example, the dataset was created on March 19th and the snapshot was created on March 23rd. In conclusion, Shadow Copies for Shared Folders provides a straightforward way for users to view or recover files from ZFS snapshots.  The Windows desktop provides an easy to use, intuitive GUI and no configuration is required to use or access previous versions of files or folders.

  • Blank desktop when logging in via xrdp

    - by nitefrog
    I am trying to access Ubuntu 11.10 using Remote Desktop from a Win 7 machine. I installed xrdp. I launch the Windows remote desktop client and login in. I then get prompted for the user name and password. It then logs in, but all I see is the background, no menus, nothing. I have to kill remote desktop by closing it. Even if I right click , nothing. Any ideas??? The only reason I even went down the RDP road was that VNC would not work either, even after I enabled desktop sharing. I am in a bind as I need to connect to Ubuntu via Windows. In version 8 Ubuntu this was not an issue and it just worked.

  • Keeping Entitlements in Check

    - by Naresh Persaud
    Thanks for going the webcast on keeping entitlements in check. As a follow up, I have attached the slides to the webcast. The webcast will be available on demand shortly via IOUG.   A few key takeaways: Application security means applying both preventive and detective controls. Audit and security groups need the combination of both access certification and runtime dynamic authorization. Today, security policy is largely fragmented and brittle to change. The result is audit exposure for highly regulated applications.  By addressing the entire value chain of application security with a comprehensive platform approach, organizations can reduce the risk and improve compliance.    Ioug webcast entitlements in check View more PowerPoint from OracleIDM

  • Browser based UI Customization with Oracle Identity Management 11gR2

    - by B Shashikumar
    Business users need user interfaces that are not only friendly but also easily customizable. However the downside of any customization project is the cost and complexity involved in developing, testing, deploying, and managing custom code. And equally critical is the challenge of ensuring customizations stay intact through product upgrades.To overcome these challenges, Oracle Identity Management 11gR2 now includes a Durable UI Configuration Framework which lets customers make complex UI customizations all from with the confines of a web browser. I recently sat down with Clayton Donley, Senior Director of Development for Oracle Identity and Access Management products. In this podcast, we examine how this new capability in Oracle Identity Management around browser based UI customization can reduce costs and complexity of customization while simplifying self service integration with corporate portal strategies.

  • File manager (Nautilus) hangs or is ultra slow when listing contents of ssh/sftp server

    - by NahsiN
    I used to use File -- Connect to server to connect to my remote ssh a lot before 12.04/11.10. But now in a fresh install of 12.04, whenever I try to access the remote files, nautilus either always hangs or is ultra slow (5 mins) in listing the directory contents. Most of the time I have to force quit or xkill. Mounting using SSHFS works fine. The ssh server is fast and it works fine via putty, mc (using fish) and normal terminal. I also installed nautilus in Lubuntu 12.04 (virtualbox) and to my surprise, browsing is fast and smooth. Both versions of nautilus are at 3.4.2 thus I am led to believe the problem might be lying somewhere in Ubuntu 12.04. But I am clueless. All suggestions welcome. I really need to solve this problem.

  • Access Control Service: Handling Errors

    - by Your DisplayName here!
    Another common problem with external authentication is how to deal with sign in errors. In active federation like WS-Trust there are well defined SOAP faults to communicate problem to a client. But with web applications, the error information is typically generated and displayed on the external sign in page. The relying party does not know about the error, nor can it help the user in any way. The Access Control Service allows to post sign in errors to a specified page. You setup this page in the relying party registration. That means that whenever an error occurs in ACS, the error information gets packaged up as a JSON string and posted to the page specified. This way you get structued error information back into you application so you can display a friendlier error message or log the error. I added error page support to my ACS2 sample, which can be downloaded here. How to turn the JSON error into CLR types The JSON schema is reasonably simple, the following class turns the JSON into an object: [DataContract] public class AcsErrorResponse {     [DataMember(Name = "context", Order = 1)]     public string Context { get; set; }     [DataMember(Name = "httpReturnCode", Order = 2)]     public string HttpReturnCode { get; set; }     [DataMember(Name = "identityProvider", Order = 3)]        public string IdentityProvider { get; set; }     [DataMember(Name = "timeStamp", Order = 4)]     public string TimeStamp { get; set; }     [DataMember(Name = "traceId", Order = 5)]     public string TraceId { get; set; }     [DataMember(Name = "errors", Order = 6)]     public List<AcsError> Errors { get; set; }     public static AcsErrorResponse Read(string json)     {         var serializer = new DataContractJsonSerializer( typeof(AcsErrorResponse));         var response = serializer.ReadObject( new MemoryStream(Encoding.Default.GetBytes(json))) as AcsErrorResponse;         if (response != null)         {             return response;         }         else         {             throw new ArgumentException("json");         }     } } [DataContract] public class AcsError {     [DataMember(Name = "errorCode", Order = 1)]     public string Code { get; set; }             [DataMember(Name = "errorMessage", Order = 2)]     public string Message { get; set; } } Retrieving the error information You then need to provide a page that takes the POST and deserializes the information. My sample simply fills a view that shows all information. But that’s for diagnostic/sample purposes only. You shouldn’t show the real errors to your end users. public class SignInErrorController : Controller {     [HttpPost]     public ActionResult Index()     {         var errorDetails = Request.Form["ErrorDetails"];         var response = AcsErrorResponse.Read(errorDetails);         return View("SignInError", response);     } } Also keep in mind that the error page is an anonymous page and that you are taking external input. So all the usual input validation applies.

  • Why am I unable to reach local network computers, but able to browse the web?

    - by Igor Zinov'yev
    I have a weird problem. Today after turning my Ubuntu 9.10 PC on I can't connect to my local network, but I can use the Internet. We have a single Windows 2003 server machine that acts as a local main DNS server, DHCP server and a domain controller. Although it seems to give me the local IP address, I can not ping it, as well as any other machine on the net. I have tried all of the below and it didn't help: Rebooting; Reconnecting to the network; Forcing the dhclient to renew the IP address; Deleting and creating new connection profiles; Plugging my machine into another network outlet; Maybe it has something to do with routing, because I have tampered with routing tables the day before, but the tables seem ok to me: $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 vboxnet0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 Our LAN uses a D-Link DI-604 router, and it looks to me as if I am connected to the network outside the router. I can not even access its administration page. Please at least suggest what I can do to solve this. P.S. What seems strangest to me is that I can access the PC in question from outside the network by opening a port on the router. I have managed to ssh to it from outside, but I still can't ping nothing on the inside. P.P.S Today I tried reinstalling network-manager with --purge option, but it did no good. After that I created a new DCHP reservation for my PC in order to change my local IP, but that didn't change anything either. My PC is able to get a DHCP offer, but then it's unable to connect to any local computers. I am desperate.

  • Host multiple domains with Apache on a VPS

    - by Kunal
    Hi I have recently bought a windows VPS and installed apache, mysql using xampp. All services are running fine. I can access the hosted site using the IP of VPS but what I need to do is host multiple domains on that server. Actually my requirement was to use htaccess on a php based site but the site had to access data from ms sql server as well. So needed to enable php_mssql.dll in the php.ini which no shared hosting was supporting. Had to go for this VPS. Plesk was installed by default but as htaccess wont work with IIS, I had to stop IIS service and install apache there. Now all is well, but I need to find a way to host multiple domains there. When I bought the VPS they hosting people sent me the dedicated IP of the server and also I have the 2 name servers required to host domains. What is the next step? Exactly which file I need to modify to get things done? Please help! Any kind of help is much appreciated. Thanks in advance for all of your kind help and time.

  • How do I cancel windows server 2003 repair install?

    - by Kilgore2k
    System: Windows 2003 Server Enterprise Scenario: NTDS db is corrupt and all attempts to fix with esentutl fail. Ran chkdsk which seemed to repair disk error and give access to the ntds.dit file but still esentutl fails. (Attached the drive to a different server to run the esentutl) Error: Access to source database '[path to copy of]/ntds.dit' failed with Jet error -1022. Operation terminated with error -1022 (JET_errDiskIO, Disk IO error) after 0.170 seconds. This error occurs on any disk I cpoy the files to including original location in C:\WINDOWS\NTDS\ Now enter the "Stupid!" and "what was I thinking!?" part (must be the late hour...) Stupid: No updated backup - after using a backup I get a network password error in the lsass error. what was I thinking!?: Started the install repair from the original CD but the install fails since the AD fails to start. Now I cant boot into any mode (safe mode, AD restore etc) nor complete the repair install. I would really like to avoid a fresh install since I have the Exchange server on this DC and would rather migrate to a new server than have to start from scratch. Thanks!

  • How to access a row from af:table out of context

    - by Vijay Mohan
    Scenario : Lets say you have an adf table in a jsff and it is included as af:region inside other page(parent page).Now your requirement is to access some specific rows from the table and do some operations. Now, since you are aceessing the table outside the context in which it is present, so first you will have to setup the context and then you can use the visitCallback mechanism to do the opeartions on table. Here is the sample code: ================= final RichTable table = this.getRichTable();         FacesContext facesContext = FacesContext.getCurrentInstance();         VisitContext visitContext =   RequestContext.getCurrentInstance().createVisitContext(facesContext,null, EnumSet.of(VisitHint.SKIP_TRANSIENT,VisitHint.SKIP_UNRENDERED), null);         //Annonymous call         UIXComponent.visitTree(visitContext,facesContext.getViewRoot(),new VisitCallback(){             public VisitResult visit(VisitContext context, UIComponent target)               {                   if (table != target)                   {                     return VisitResult.ACCEPT;                   }                   else if(table == target)                   {                       //Here goes the Actual Logic                       Iterator selection = table.getSelectedRowKeys().iterator();                       while (selection.hasNext()) {                           Object key = selection.next();                           //store the original key                           Object origKey = table.getRowKey();                           try {                               table.setRowKey(key);                               Object o = table.getRowData();                               JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)o;                               Row row = rowData.getRow();                               System.out.println(row.getAttribute(0));                           }                           catch(Exception ex){                               ex.printStackTrace();                           }                           finally {                               //restore original key                               table.setRowKey(origKey);                           }                       }                   }                   return VisitResult.COMPLETE;               }         });
