• How to use Oracle AQ with Message-Driven Beans in Weblogic

  - by lukasz.romaszewski(at)oracle.com

  Welcome to the IMC blog! This post shows how to use Oracle AQ as an underlying JMS implementation with MDBs in Weblogic. MDB's can be very useful when you want to integrate your database logic with your Java application. Normally JEE application invokes the code inside the database. But in some cases you want the DB to initiate the asynchronous call and have your Java application do the actual processing. This is also very useful when you want to integrate JEE code with the Oracle Forms application.The post has been based on the following OTN documentation: Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} http://download.oracle.com/docs/cd/E14571_01/web.1111/e13738/aq_jms.htm#CJACBCEJDetailed instruction is here:How to connect MDB to Oracle AQ.pdf v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Normal 0 false false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} You can also download a sample JDeveloper application here:MDB_AQApplication.zipPlease feel free to ask questions and put comments.Merry Christmas and Happy New Year!

• Part 9: EBS Customizations, how to track

  - by volker.eckardt(at)oracle.com

  In the previous blogs we were concentrating on the preparation tasks. We have defined standards, we know about the tools and techniques we will start with. Additionally, we have defined the modification strategy, and how to handle such topics best. Now we are ready to take the requirements! Such requirements coming over in spreadsheets, word files (like GAP documents), or in any other format. As we have to assign some attributes, we start numbering all that and assign a short name to each of these requirements (=CEMLI reference). We may also have already a Functional person assigned, and we might involve someone from the tech team to estimate, and we like to assign a status such as 'planned', 'estimated' etc. All these data are usually kept in spreadsheets, but I would put them into a database (yes, I am from Oracle :). If you don't have any good looking and centralized application already, please give a try with Oracle APEX. It should be up and running in a day and the imported sheets are than manageable concurrently!  For one of my clients I have created this CEMLI-DB; in between enriched with a lot of additional functionality, but initially it was just a simple centralized CEMLI tracking application. Why I am pointing out again the centralized method to manage such data? Well, your data quality will dramatically increase, if you let your project members see (also review and update) "your" data.  APEX allows you to filter, sort, print, and also export. And if you can spend some time to define proper value lists, everyone will gain from. APEX allows you to work in 'agile' mode, means you can improve your application step by step. Let's say you like to reference a document, or even upload the same, you can do that. Or, you need to classify the CEMLIs by release, just add this release field, same for business area or CEMLI type. One CEMLI record may then look like this: Prepare one or two (online) reports, to be ready to present your "workload" to the project management. Use such extracts also when you work offline (to prioritize etc.). But as soon as you are again connected, feed the data back into the central application. Note: I have combined this application with an additional issue tracker.  Here the most important element is the CEMLI reference, which acts as link to any other application (if you are not using APEX also as issue tracker :).  Please spend a minute to define such a reference (see blog Part 8: How to name Customizations).   Summary: Building the bridge from Gap analyse to the development has to be done in a controlled way. Usually the information is provided differently, but it is suggested to collect all requirements centrally. Oracle APEX is a great solution to enter and maintain such information in a structured, but flexible way. APEX helped me a lot to work with distributed development teams during the complete development cycle.

• Creating a branch for every Sprint

  - by Martin Hinshelwood

  There are a lot of developers using version control these days, but a feature of version control called branching is very poorly understood and remains unused by most developers in favour of Labels. Most developers think that branching is hard and complicated. Its not! What is hard and complicated is a bad branching strategy. Just like a bad software architecture a bad branch architecture, or one that is not adhered to can prove fatal to a project. We I was at Aggreko we had a fairly successful Feature branching strategy (although the developers hated it) that meant that we could have multiple feature teams working at the same time without impacting each other. Now, this had to be carefully orchestrated as it was a Business Intelligence team and many of the BI artefacts do not lend themselves to merging. Today at SSW I am working on a Scrum team delivering a product that will be used by many hundreds of developers. SSW SQL Deploy takes much of the pain out of upgrading production databases when you are not using the Database projects in Visual Studio. With Scrum each Scrum Team works for a fixed period of time on a single sprint. You can have one or more Scrum Teams involved in delivering a product, but all the work must be merged and tested, ready to be shown to the Product Owner at the the Sprint Review meeting at the end of the current Sprint. So, what does this mean for a branching strategy? We have been using a “Main” (sometimes called “Trunk”) line and doing a branch for each sprint. It’s like Feature Branching, but with only ONE feature in operation at any one time, so no conflicts Figure: DEV folder containing the Development branches.   I know that some folks advocate applying a Label at the start of each Sprint and then rolling back if you need to, but I have always preferred the security of a branch. Like: being able to create a release from Main that has Sprint3 code even while Sprint4 is being worked on. being sure I can always create a stable build on request. Being able to guarantee a version (labels are not auditable) Be able to abandon the sprint without having to delete the code (rare I know, but would be a mess if it happened) Being able to see the flow of change sets through to a safe release It helps you find invalid dependencies when merging to Main as there may be some file that is in everyone’s Sprint branch, but never got checked in. (We had this at the merge of Sprint2) If you are always operating in this way as a standard it makes it easier to then add more scrum teams in the future. Muscle memory of this way of working. Don’t Like: Additional DB space for the branches Baseless merging between sprint branches when changes are directly ported Note: I do not think we will ever attempt this! Maybe a bit tougher to see the history between sprint branches since the changes go up through Main and down to another sprint branch Note: What you would have to do is see which Sprint the changes were made in and then check the history he same file in that Sprint. A little bit of added complexity that you would have to do anyway with multiple teams. Over time, you can end up with a lot of old unused sprint branches. Perhaps destroy with /keephistory can help in this case. Note: We ALWAYS delete the Sprint branch after it has been merged into Main. That is the theory anyway, and as you can see from the images Sprint2 has already been deleted. Why take the chance of having a problem rolling back or wanting to keep some of the code, when you can just abandon a branch and start a new one? It just seems easier and less painful to use a branch to me! What do you think?   Technorati Tags: TFS,TFS2010,Software Development,ALM,Branching

• Entity Framework - Single EMDX Mapping Multiple Database

  - by michaelalisonalviar

  Because of my recent craze on Entity Framework thanks to Sir Humprey, I have continuously searched the Internet for tutorials on how to apply it to our current system. So I've come to learn that with EF, I can eliminate the numerous coding of methods/functions for CRUD operations, my overly used assigning of connection strings, Data Adapters or Data Readers as Entity Framework will map my desired database and will do its magic to create entities for each table I want (using EF Powertool) and does all the methods/functions for my Crud Operations. But as I begin applying it to a new project I was assigned to, I realized our current server is designed to contain each similar entities in different databases. For example Our lookup tables are stored in LookupDb, Accounting-related tables are in AccountingDb, Sales-related tables in SalesDb. My dilemma is I have to use an existing table from LookupDB and use it as a look-up for my new table. Then I have found Miss Rachel's Blog (here)Thank You Miss Rachel!  which enables me to let EF think that my TableLookup1 is in the AccountingDB using the following steps. Im on VS 2010, I am using C# , Using Entity Framework 5, SQL Server 2008 as our DB ServerStep 1:Creating A SQL Synonym. If you want a more detailed discussion on synonyms, this was what i have read -> (link here). To simply put it, A synonym enabled me to simplify my query for the Look-up table when I'm using the AccountingDB fromSELECT [columns] FROM LookupDB.dbo.TableLookup1toSELECT [columns] FROM TableLookup1Syntax: CREATE SYNONYM  TableLookup1(1) FOR LookupDB.dbo.TableLookup1 (2)1. What you want to call the table on your other DB2. DataBaseName.schema.TableNameStep 2: We will now follow Miss Rachel's steps. you can either visit the link on the original topic I posted earlier or just follow the step I made.1. I created a Visual Basic Solution that will contain the 4 projects needed to complete the merging2. First project will contain the edmx file pointing to the AccountingDB3. Second project will contain the edmx file pointing to the LookupDB4. Third Project will will be our repository of the merged edmx file. Create an edmx file pointing To AccountingDB as this the database that we created the Synonym on.Reminder: Aside from using the same name for the Entities, please make sure that you have the same Model Namespace for all your Entities  5. Fourth project that will contain the beautiful EDMX merger that Miss Rachel created that will free you from Hard coding of the merge/recoding the Edmx File of the third project everytime a change is done on either one of the first two projects' Edmx File.6. Run the solution, but make sure that on the solutions properties Single startup project is selected and the project containing the EDMX merger is selected.7. After running the solution, double click on the EDMX file of the 3rd project and set Lazy Loading Enabled = False. This will let you use the tables/entities that you see in that EDMX File.8. Feel free to do your CRUD Operations.I don't know if EF 5 already has a feature to support synonyms as I am still a newbie on that aspect but I have seen a linked where there are supposed suggestions on Entity Framework upgrades and one is the "Support for multiple databases"  So that's it! Thanks for reading!

• Ubuntu 12.04 - No sound - HELP!

  - by Bruno Tacca

  I'm panicking... my sound stopped working after I tried to set-up my notebook speakers, plus two headphone jacks... My idea was to multichannel the sound to 3 channels, built-in speakers, and sound-card 2 headphone jacks. After a couple efforts I did it with 2 channels, speakers and 1 headphone jack, but the other wasn't working. After more tries and tries, sound stop working. I just want my sound back... crying like a baby on the floor. And, if possible, but not necessary, a simple guide to active the 3 channels. xD I will post the diagnosis according to https://help.ubuntu.com/community/SoundTroubleshootingProcedure STEP 1 Did it, still no sound. STEP 2 Did it, still no sound. STEP 3 and #STEP 4 (I removed the log cause there is a limit of characters to be posted.) The log can be found here: https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/238653 STEP 5 Rebooted, still no sound. STEP 6 Did it. In the Output Devices tab, nothing is muted. I play a music with the Rhythmbox Music Player, I don't hear anything but in the pavucontrol I can see in the Built-in Audio Analog Stereo a sound bar shaking... but, no sound. STEP 7 In alsamixer, AlsaMixer v1.0.25 Card: HDA Intel PCH Chip: Creative CA0132 information View: F3:[Playback] F4: Capture F5: All Item: Headphone [dB gain: 25.00, 25.00] Then, I have 5 columns Headphone, Speaker, PCM, S/PDIF, S/PDIF Default PCM A little weird when I try to mute the Headphone and the Speaker, here what happens: Starting both unmutted, mutting headphone cause speaker being mutted automaticaly. Starting both unmutted, mutting speaker cause headphone being mutted automaticaly. Starting both mutted, possible to unmute both separately. STEP 8 I cannot hear sound on both (headphone and/or speaker). STEP 9 Dual boot... Restarted, windows was with sound at max volume. Restarted again, still no sound at ubuntu. I heard something when ubuntu started, a little noise, then silence again. The sound icon always start mutted, after unmutting, I have no sound. STEP 10 I dont have this command in my ubuntu. STEP 11 Tried at STEP 8, no sound. There are no problem with jumpers or hardware, cause I have sound working on windows. STEP 12 No way to open my alienware and loss the warranty x.X" STEP 13 I think it's loaded, judging my the logs STEP 14 Alienware M17xR4, the hardware is listed in the logs above, at STEP 4. There are two headphone hacks, one with just an headphone printed above, and the other with an headset (with mic) printed, there is a mic jack too, and a spdif (optical) too. STEP 15 I dont want to enable S/PDIF STEP 16 I never used the HDMI output, yet... Thanks in advance. I hope I listed all the information you need.

• Introducing MySQL for Excel

  - by Javier Treviño

  As part of the new product initiatives of the MySQL on Windows group we released a tool that makes the task of getting data in and out of a MySQL Database very friendly and intuitive, and we paired it with one of the preferred applications for data analysis and manipulation in Windows platforms, MS Excel. Welcome to MySQL for Excel, an add-in that is installed and accessed from within the MS Excel’s Data tab offering a wizard-like interface arranged in an elegant yet simple way to help users browse MySQL Schemas, Tables, Views and Procedures and perform data operations against them using MS Excel as the vehicle to drive the data in and out MySQL Databases. One of the coolest features we had in mind designing MySQL for Excel is simplicity. MS Excel is simple and easy to work with, thus liked by many Windows users because they don’t have to be software gurus to use it.  We applied the same principle by targeting MySQL for Excel to any kind of user, so if you are already familiarized with Excel’s interface you will find yourself working with MySQL data in no time. MySQL for Excel is shipped within the MySQL Installer as one of the tools in the suite; if prerequisites are already installed (.NET Framework 4.0, Visual Studio Tools for Office 4.0 and of course MS Office), installing the add-in involves a very few clicks and no further setup to use it. Being an Excel Add-In there is no executable file involved after the installation, running MS Excel and opening the add-in from its Data tab is all that is required. MySQL for Excel automatically integrates with MySQL Workbench (if installed) to share the same connections to MySQL Server installations, that way connections are defined just once in either product saving time.  Opening the Add-In brings the Welcome Panel at the right side of the Excel main window from which connections to MySQL Servers are shown grouped by Local VS Remote connections; then users can open any of those connections by double-clicking it and entering the password of the used account.  Additionally a user can create a connection by clicking on the New Connection action label or edit connections through MySQL Workbench (if installed) by clicking on the Manage Connections action label. Once a connection is opened, the Schema Selection panel is shown, at the top of it the selected connection (connection name, hostname/IP and username). Just below, a list of schemas is displayed where User Schemas are grouped first followed by System Schemas; users can double-click any selected schema to go to the next panel or select a schema and clicking the Next > button. Users can alternatively click on the < Back button to go back to the Welcome Panel to close the current connection and open a new one; also by clicking the Create New Schema action label they can create an empty new schema. Once a schema is opened the DB Object Selection panel is shown, this is actually the place where the fun stuff happens; from here users are able to perform actions against MySQL Tables, Views and Procedures. ">The actions available here are about importing data from a MySQL Table, View or Procedure to Excel, exporting Excel data to a new MySQL Table, appending Excel data to an existing MySQL Table or editing a MySQL Table’s data by using an Excel Worksheet as a user interface to update data in any row/column, insert new rows or delete existing rows in a very easy and friendly way. More blog posts will follow describing all of these actions, so stay tuned! Remember that your feedback is very important for us, so drop us a message: · MySQL on Windows (this) Blog - https://blogs.oracle.com/MySqlOnWindows/ · Forum - http://forums.mysql.com/list.php?172 · Facebook - http://www.facebook.com/mysql Cheers!

• Logging connection strings

  If you some of the dynamic features of SSIS such as package configurations or property expressions then sometimes trying to work out were your connections are pointing can be a bit confusing. You will work out in the end but it can be useful to explicitly log this information so that when things go wrong you can just review the logs. You may wish to develop this idea further and encapsulate such logging into a custom task, but for now lets keep it simple and use the Script Task. The Script Task code below will raise an Information event showing the name and connection string for a connection. Imports System Imports Microsoft.SqlServer.Dts.Runtime Public Class ScriptMain Public Sub Main() Dim fireAgain As Boolean ' Get the connection string, we need to know the name of the connection Dim connectionName As String = "My OLE-DB Connection" Dim connectionString As String = Dts.Connections(connectionName).ConnectionString ' Format the message and log it via an information event Dim message As String = String.Format("Connection ""{0}"" has a connection string of ""{1}"".", _ connectionName, connectionString) Dts.Events.FireInformation(0, "Information", message, Nothing, 0, fireAgain) Dts.TaskResult = Dts.Results.Success End Sub End Class Building on that example it is probably more flexible to log all connections in a package as shown in the next example. Imports System Imports Microsoft.SqlServer.Dts.Runtime Public Class ScriptMain Public Sub Main() Dim fireAgain As Boolean ' Loop through all connections in the package For Each connection As ConnectionManager In Dts.Connections ' Get the connection string and log it via an information event Dim message As String = String.Format("Connection ""{0}"" has a connection string of ""{1}"".", _ connection.Name, connection.ConnectionString) Dts.Events.FireInformation(0, "Information", message, Nothing, 0, fireAgain) Next Dts.TaskResult = Dts.Results.Success End Sub End Class By using the Information event it makes it readily available in the designer, for example the Visual Studio Output window (Ctrl+Alt+O) or the package designer Execution Results tab, and also allows you to readily control the logging by choosing which events to log in the normal way. Now before somebody starts commenting that this is a security risk, I would like to highlight good practice for building connection managers. Firstly the Password property, or any other similar sensitive property is always defined as write-only, and secondly the connection string property only uses the public properties to assemble the connection string value when requested. In other words the connection string will never contain the password. I have seen a couple of cases where this is not true, but that was just bad development by third-parties, you won’t find anything like that in the box from Microsoft.   Whilst writing this code it made me wish that there was a custom log entry that you could just turn on that did this for you, but alas connection managers do not even seem to support custom events. It did however remind me of a very useful event that is often overlooked and fits rather well alongside connection string logging, the Execute SQL Task’s custom ExecuteSQLExecutingQuery event. To quote the help reference Custom Messages for Logging - Provides information about the execution phases of the SQL statement. Log entries are written when the task acquires connection to the database, when the task starts to prepare the SQL statement, and after the execution of the SQL statement is completed. The log entry for the prepare phase includes the SQL statement that the task uses. It is the last part that is so useful, how often have you used an expression to derive a SQL statement and you want to log that to make sure the correct SQL is being returned? You need to turn it one, by default no custom log events are captured, but I’ll refer you to a walkthrough on setting up the logging for ExecuteSQLExecutingQuery by Jamie.

• SQL Server Transaction Marks: Restoring multiple databases to a common relative point

  - by Mladen Prajdic

  We’re all familiar with the ability to restore a database to point in time using the RESTORE WITH STOPAT statement. But what if we have multiple databases that are accessed from one application or are modifying each other? And over multiple instances? And all databases have different workloads? And we want to restore all of the databases to some known common relative point? The catch here is that this common relative point isn’t the same point in time for all databases. This common relative point in time might be now in DB1, now-1 hour in DB2 and yesterday in DB3. And we don’t know the exact times. Let me introduce you to Transaction Marks. When we run a marked transaction using the WITH MARK option a flag is set in the transaction log and a row is added to msdb..logmarkhistory table. When restoring a transaction log backup we can restore to either before or after that marked transaction. The best thing is that we don’t even need to have one database modifying another database. All we have to do is use a marked transaction with the same name in different database. Let’s see how this works with an example. The code comments say what’s going on. USE master GOCREATE DATABASE TestTxMark1GOUSE TestTxMark1GOCREATE TABLE TestTable1( ID INT, VALUE UNIQUEIDENTIFIER) -- insert some data into the table so we can have a starting pointINSERT INTO TestTable1SELECT ROW_NUMBER() OVER(ORDER BY number) AS RN, NULLFROM master..spt_valuesORDER BY RNSELECT *FROM TestTable1GO-- TAKE A FULL BACKUP of the databseBACKUP DATABASE TestTxMark1 TO DISK = 'c:\TestTxMark1.bak'GO USE master GOCREATE DATABASE TestTxMark2GOUSE TestTxMark2GOCREATE TABLE TestTable2( ID INT, VALUE UNIQUEIDENTIFIER)-- insert some data into the table so we can have a starting pointINSERT INTO TestTable2SELECT ROW_NUMBER() OVER(ORDER BY number) AS RN, NEWID()FROM master..spt_valuesORDER BY RNSELECT *FROM TestTable2GO-- TAKE A FULL BACKUP of our databseBACKUP DATABASE TestTxMark2 TO DISK = 'c:\TestTxMark2.bak'GO -- start a marked transaction that modifies both databasesBEGIN TRAN TxDb WITH MARK -- update values from NULL to random value UPDATE TestTable1 SET VALUE = NEWID(); -- update first 100 values from random value -- to NULL in different DB UPDATE TestTxMark2.dbo.TestTable2 SET VALUE = NULL WHERE ID <= 100;COMMITGO     -- some time goes by here -- with various database activity... -- We see two entries for marks in each database. -- This is just informational and has no bearing on the restore itself.SELECT * FROM msdb..logmarkhistory USE masterGO-- create a log backup to restore to mark pointBACKUP LOG TestTxMark1 TO DISK = 'c:\TestTxMark1.trn'GO-- drop the database so we can restore it backDROP DATABASE TestTxMark1GO USE masterGO-- create a log backup to restore to mark pointBACKUP LOG TestTxMark2 TO DISK = 'c:\TestTxMark2.trn'GO-- drop the database so we can restore it backDROP DATABASE TestTxMark2GO -- RESTORE THE DATABASE BACK BEFORE OUR TRANSACTION-- restore the full backup RESTORE DATABASE TestTxMark1 FROM DISK = 'c:\TestTxMark1.bak' WITH NORECOVERY;-- restore the log backup to the transaction markRESTORE LOG TestTxMark1 FROM DISK = 'c:\TestTxMark1.trn' WITH RECOVERY, -- recover to state before the transaction STOPBEFOREMARK = 'TxDb'; -- recover to state after the transaction -- STOPATMARK = 'TxDb';GO -- RESTORE THE DATABASE BACK BEFORE OUR TRANSACTION-- restore the full backup RESTORE DATABASE TestTxMark2 FROM DISK = 'c:\TestTxMark2.bak' WITH NORECOVERY;-- restore the log backup to the transaction markRESTORE LOG TestTxMark2 FROM DISK = 'c:\TestTxMark2.trn' WITH RECOVERY, -- recover to state before the transaction STOPBEFOREMARK = 'TxDb'; -- recover to state after the transaction -- STOPATMARK = 'TxDb';GO USE TestTxMark1-- we restored to time before the transaction -- so we have NULL values in our tableSELECT * FROM TestTable1 USE TestTxMark2-- we restored to time before the transaction -- so we DON'T have NULL values in our tableSELECT * FROM TestTable2   Transaction marks can be used like a crude sync mechanism for cross database operations. With them we can mark our databases with a common “restore to” point so we know we have a valid state between all databases to restore to.

• A (Late) Meme Monday Post: On SQLFamily

  - by Argenis

    Yesterday a member of the SQL community who I deeply admire sent me a DM on Twitter asking whether I had done a SQLFamily post for Thomas LaRock’s (blog|@SQLRockstar) Meme Monday for November. I replied that I did not, and I regretted not having done so. A subtle DM followed my response: “Get on it, you have all week”. And indeed I must. So here’s an attempt to express some of my feelings on a community that has catapulted my career like nothing else before I embraced it. Nanos Gigantium Humeris Insidentes I stand on the shoulders of giants. My SQLFamily has given me support at all levels. Professionally and personally. There is never a lack of will to help and provide advice to others in this community. And I do my best to help. On #SQLHelp on Twitter, via email, or even on the phone. I expect no retribution, because I know that when and if I do run into problems, my SQLFamily will be there for me. I have met some of the most humble, dedicated and most professional people in the SQL community. And some of them have pretty big titles: MVPs, MCMs, Regional Mentors, and even leaders of PASS, SQLCAT members, and even PMs and Devs on the SQL Server team. All are welcome, and that includes YOU! I have also met some people that are rather reserved and don’t participate as much in the community, for whatever reason. Be as it may, let it be know to all that we are a very welcoming community – heck, some of my closest friends and people I can count on in the community have completely opposite political views. We share one goal: to get better and help others get better. Even if you are a lurker – my hope is that one day you’ll decide to give back some of what you have learned. You have to take it to the next level On one of my previous jobs as an IT Supervisor I used to tell my team all the time about the benefits of continuous education and self-driven learning. Shortly after I left that job, the company went bankrupt and some of my staff got laid off – some without any severance pay whatsoever. I eventually found out that some of them had a really hard time finding another job, because their skills were simply outdated. They had become stale professionals. Don’t be one of them. If you don’t take advantage of these learning resources, somebody else will – and that person has an advantage over you when applying for that awesome job position that got opened. There’s a severe shortage of good DBAs and DB Devs out there. What’s your excuse for not being excellent? Even if your knowledge of SQL Server is at the beginner level, really – you have no excuse to get better. Just go to SQLUniversity and learn from there. Don’t get stale! Thank You To all of you in the SQL community who put so much time and energy into helping others, my deepest gratitude to you. I can’t wait to meet you all again at the next event and share our SQL stories over a pint of beer (or a shot of Jaeger) Cheers! -Argenis

• NHibernate 3.0 and FluentNHibernate, how to get up and running&hellip;.

  - by DesigningCode

  First up. Its actually really easy. I’m not very religious about my DB tech, I don’t really care, I just want something that works.  So I’m happy to consider all options if they provide an advantage, and recently I was considering jumping from NHibernate to EF 4.0.  However before ditching NHibernate and jumping to EF 4.0 I thought I should try the head version of NHibernates trunk and the Head version of FluentNHibernate. I currently have a “Repository / Unit of Work” Framework built up around these two techs.  All up it makes my life pretty simple for dealing with databases.   The problem is the current release of NHibernate + the Linq provider wasn’t too hot for our purposes.  Especially trying to plug it into older VB.NET code.   The Linq provider spat the dummy with VB.NET lambdas.  Mainly because in C# Query().Where(l => l.Name.Contains("x") || l.Name.Contains("y")).ToList(); is not the same as the VB.NET Query().Where(Function(l) l.Name.Contains("x") Or l.Name.Contains("y")).ToList VB.NET seems to spit out … well…. something different :-) so anyways… Compiling your own version of NHibernate and FluentNHibernate.  It’s actually pretty easy! First you’ll need to install tortisesvn NAnt and Git if you don’t already have them.  NHibernate first step, get the subversion trunk https://nhibernate.svn.sourceforge.net/svnroot/nhibernate/trunk/ into a directory somewhere.  eg \thirdparty\nhibernate Then use NAnt to build it.   (if you open the .sln it will show errors in that  AssemblyInfo.cs doesn’t exist ) to build it, there is a .txt document with sample command line build instructions,  I simply used :- NAnt -D:project.config=release clean build >output-release-build.log *wait* *wait* *wait* and ta da, you will have a bin directory with all the release dlls. FluentNHibernate This was pretty simple. there’s instructions here :- http://wiki.fluentnhibernate.org/Getting_started#Installation basically, with git, create a directory, and you issue the command git clone git://github.com/jagregory/fluent-nhibernate.git and wait, and soon enough you have the source. Now, from the bin directory that NHibernate spit out, take everything and dump it into the subdirectory “fluent-nhibernate\tools\NHibernate” Now, to build, you can use rake….which a ruby build system, however you can also just open the solution and build.   Which is what I did.  I had a few problems with the references which I simply re-added using the new ones.  Once built, I just took all the NHibnerate dlls, and the fluent ones and replaced my existing NHibernate / Fluent and killed off the old linq project. All I had to change is the places that used  .Linq<T>  and replace them with .Query<T>  (which was easy as I had wrapped it already to isolate my code from such changes) and hey presto, everything worked.  Even the VB.NET linq calls. I need to do some more testing as I’ve only done basic smoke tests, but its all looking pretty good, so for now, I will stick to NHibernate!

• Using the latest (stable release) of Oracle Developer Tools for Visual Studio 11.1.0.7.20.

  - by mbcrump

  +  = Simple and safe Data connections.   This guide is for someone wanting to use the latest ODP.NET quickly without reading the official documentation. This guide will get you up and running in about 15 minutes. I have reviewed my referral link to my simple Setting up ODP.net with Win7 x64 and noticed most people were searching for one of the following terms: “how to use odp.net with vs” “setup connection odp.net” “query db using odp and vs” While my article provided links and a sample tnsnames.ora file, it really didn’t tell you how to use it. I’m hoping that this brief tutorial will help. So before we get started, you will need the following: Download the following: www.oracle.com/technology/software/tech/dotnet/utilsoft.html from oracle and install it. It is the first one on the page. Visual Studio 2008 or 2010. It should be noted that The System.Data.OracleClient namespace is the OLD .NET Framework Data Provider for Oracle. It should not be used anymore as it has been depreciated. The latest version which is what we are using is Oracle.DataAccess.Client. First things first, Add a reference to the Oracle.DataAccess.Client after you install ODP.NET   Copy and paste the following C# code into your project and replace the relevant info including the query string and you should be able to return data. I have commented several lines of code to assist in understanding what it is doing.   Lambda Expression. using System; using System.Data; using Oracle.DataAccess.Client;   namespace ConsoleApplication1 {     class Program     {         static void Main(string[] args)         {           try         {             //Setup DataSource             string oradb = "Data Source=(DESCRIPTION ="                                    + "(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521)))"                                    + "(CONNECT_DATA = (SERVICE_NAME = SERVICENAME))) ;"                                    + "Persist Security Info=True;User ID=USER;Password=PASSWORD;";                        //Open Connection to Oracle - this could be moved outside the try.             OracleConnection conn = new OracleConnection(oradb);             conn.Open();               //Create cmd and use parameters to prevent SQL injection attacks.             OracleCommand cmd = new OracleCommand();             cmd.Connection = conn;               cmd.CommandText = "select username from table where username = :username";               OracleParameter p1 = new OracleParameter("username", OracleDbType.Varchar2);             p1.Value = username;             cmd.Parameters.Add(p1);               cmd.CommandType = CommandType.Text;               OracleDataReader dr = cmd.ExecuteReader();             dr.Read();               //Contains the value of the datarow             Console.WriteLine(dr["username"].ToString());               //Disposes of objects.             dr.Dispose();             cmd.Dispose();             conn.Dispose();         }           catch (OracleException ex) // Catches only Oracle errors         {             switch (ex.Number)             {                 case 1:                     Console.WriteLine("Error attempting to insert duplicate data.");                     break;                 case 12545:                     Console.WriteLine("The database is unavailable.");                     break;                 default:                     Console.WriteLine(ex.Message.ToString());                     break;             }         }           catch (Exception ex) // Catches any error not previously caught         {                   Console.WriteLine("Unidentified Error: " + ex.Message.ToString());              }         }       }           } At this point, you should have a working Program that returns data from an oracle database. If you are still having trouble then drop me a line and I will be happy to assist. As of this writing, oracle has announced the latest beta release of ODP.NET 11.2.0.1.1 Beta.  This release includes .NET Framework 4 and .NET Framework 4 Client Profile support. You may want to hold off on this version for a while as its BETA, and I wouldn’t want any production code using any BETA software.

• SSIS - Connect to Oracle on a 64-bit machine (Updated for SSIS 2008 R2)

  - by jorg

  We recently had a few customers where a connection to Oracle on a 64 bit machine was necessary. A quick search on the internet showed that this could be a big problem. I found all kind of blog and forum posts of developers complaining about this. A lot of developers will recognize the following error message: Test connection failed because of an error in initializing provider. Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed. After a lot of searching, trying and debugging I think I found the right way to do it! Problems Because BIDS is a 32 bit application, as well on 32 as on 64 bit machines, it cannot see the 64 bit driver for Oracle. Because of this, connecting to Oracle from BIDS on a 64 bit machine will never work when you install the 64 bit Oracle client. Another problem is the "Microsoft Provider for Oracle", this driver only exists in a 32 bit version and Microsoft has no plans to create a 64 bit one in the near future. The last problem I know of is in the Oracle client itself, it seems that a connection will never work with the instant client, so always use the full client. There are also a lot of problems with the 10G client, one of it is the fact that this driver can't handle the "(x86)" in the path of SQL Server. So using the 10G client is no option! Solution Download the Oracle 11G full client. Install the 32 AND the 64 bit version of the 11G full client (Installation Type: Administrator) and reboot the server afterwards. The 32 bit version is needed for development from BIDS with is 32 bit, the 64 bit version is needed for production with the SQLAgent, which is 64 bit. Configure the Oracle clients (both 32 and 64 bits) by editing  the files tnsnames.ora and sqlnet.ora. Try to do this with an Oracle DBA or, even better, let him/her do this. Use the "Oracle provider for OLE DB" from SSIS, don't use the "Microsoft Provider for Oracle" because a 64 bit version of it does not exist. Schedule your packages with the SQLAgent. Background information Visual Studio (BI Dev Studio)is a 32bit application. SQL Server Management Studio is a 32bit application. dtexecui.exe is a 32bit application. dtexec.exe has both 32bit and 64bit versions. There are x64 and x86 versions of the Oracle provider available. SQLAgent is a 64bit process. My advice to BI consultants is to get an Oracle DBA or professional for the installation and configuration of the 2 full clients (32 and 64 bit). Tell the DBA to download the biggest client available, this way you are sure that they pick the right one ;-) Testing if the clients have been installed and configured in the right way can be done with Windows ODBC Data Source Administrator: Start... Programs... Administrative tools... Data Sources (ODBC) ADITIONAL STEPS FOR SSIS 2008 R2 It seems that, unfortunately, some additional steps are necessary for SQL Server 2008 R2 installations: 1. Open REGEDIT (Start… Run… REGEDIT) on the server and search for the following entry (for the 32 bits driver): HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC\MTxOCI Make sure the following values are entered: 2. Next, search for (for the 64 bits driver): HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\MSDTC\MTxOCI Make sure the same values as above are entered. 3. Reboot your server.

• MaxTotalSizeInBytes - Blind spots in Usage file and Web Analytics Reports

  - by Gino Abraham

  Originally posted on: http://geekswithblogs.net/GinoAbraham/archive/2013/10/28/maxtotalsizeinbytes---blind-spots-in-usage-file-and-web-analytics.aspx http://blogs.msdn.com/b/sharepoint_strategery/archive/2012/04/16/usage-file-and-web-analytics-reports-with-blind-spots.aspx In my previous post (Troubleshooting SharePoint 2010 Web Analytics), I referenced a problem that can occur when exceeding the daily partition size for the LoggingDB, which generates the ULS message “[Partition] has exceeded the max bytes”. Below, I wanted to provide some additional info on this particular issue and help identify some options if this occurs. As an aside, this post only applies if you are missing portions of Usage data - think blind spots on intermittent days or user activity regularly sparse for the afternoon/evening. If this fits your scenario - read on. But if Usage logs are outright missing, go check out my Troubleshooting post first.  Background on the problem:The LoggingDB database has a default maximum size of ~6GB. However, SharePoint evenly splits this total size into fixed sized logical partitions – and the number of partitions is defined by the number of days to retain Usage data (by default 14 days). In this case, 14 partitions would be created to account for the 14 days of retention. If the retention were halved to 7 days, the LoggingDBwould be split into 7 corresponding partitions at twice the size. In other words, the partition size is generally defined as [max size for DB] / [number of retention days].Going back to the default scenario, the “max size” for the LoggingDB is 6200000000 bytes (~6GB) and the retention period is 14 days. Using our formula, this would be [~6GB] / [14 days], which equates to 444858368 bytes (~425MB) per partition per day. Again, if the retention were halved to 7 days (which halves the number of partitions), the resulting partition size becomes [~6GB] / [7 days], or ~850MB per partition.From my experience, when the partition size for any given day is exceeded, the usage logging for the remainder of the day is essentially thrown away because SharePoint won’t allow any more to be written to that day’s partition. The only clue that this is occurring (beyond truncated usage data) is an error such as the following that gets reported in the ULS:04/08/2012 09:30:04.78    OWSTIMER.EXE (0x1E24)    0x2C98    SharePoint Foundation    Health    i0m6     High    Table RequestUsage_Partition12 has 444858368 bytes that has exceeded the max bytes 444858368It’s also worth noting that the exact bytes reported (e.g. ‘444858368’ above) may slightly vary among farms. For example, you may instead see 445226812, 439123456, or something else in the ballpark. The exact number itself doesn't matter, but this error message intends to indicates that the reporting usage has exceeded the partition size for the given day.What it means:The error itself is easy to miss, which can lead to substantial gaps in the reporting data (your mileage may vary) if not identified. At this point, I can only advise to periodically check the ULS logs for this message. Down the road, I plan to explore if [Developing a Custom Health Rule] could be leveraged to identify the issue (If you've ever built Custom Health Rules, I'd be interested to hear about your experiences). Overcoming this issue also poses a challenge, with workaround options including:Lower the retentionBecause the partition size is generally defined as [max size] / [number of retention days], the first option is to lower the number of days to retain the data – the lower the retention, the lower the divisor and thus a bigger partition. For example, halving the retention from 14 to 7 days would halve the number of partitions, but double the partition size to ~850MB (e.g. [6200000000 bytes] / [7 days] = ~850GB partitions). Lowering it to 2 days would result in two ~3GB partitions… and so on.Recreate the LoggingDB with an increased sizeThe property MaxTotalSizeInBytes is exposed by OM code for the SPUsageDefinition object and can be updated with the example PowerShell snippet below. However, updating this value has no immediate impact because this size only applies when creating a LoggingDB. Therefore, you must create a newLoggingDB for the Usage Service Application. The gotcha: this effectively deletes all prior Usage databecause the Usage Service Application can only have a single LoggingDB.Here is an example snippet to update the "Page Requests" Usage Definition:$def=Get-SPUsageDefinition -Identity "page requests" $def.MaxTotalSizeInBytes=12400000000 $def.update()Create a new Logging database and attach to the Usage Service Application using the following command: Get-spusageapplication | Set-SPUsageApplication -DatabaseServer <dbServer> -DatabaseName <newDBname> Updated (5/10/2012): Once the new database has been created, you can confirm the setting has truly taken by running the following SQL Query (be sure to replace the database name in the following query with the name provided in the PowerShell above)SELECT * FROM [WSS_UsageApplication].[dbo].[Configuration] WITH (nolock) WHERE ConfigName LIKE 'Max Total Bytes - RequestUsage'

• WebLogic Server–Use the Execution Context ID in Applications–Lessons From Hansel and Gretel

  - by james.bayer

  I learned a neat trick this week.  Don’t let your breadcrumbs go to waste like Hansel and Gretel did!  Keep track of the code path, logs and errors for each request as they flow through the system.  Earlier this week an OTN forum post in the WLS – General category by Oracle Ace John Stegeman asked a question how to retrieve the Execution Context ID so that it could be used on an error page that a user could provide to a help desk or use to check with application administrators so they could look up what went wrong.  What is the Execution Context ID (ECID)?  Fusion Middleware injects an ECID as a request enters the system and it says with the request as it flows from Oracle HTTP Server to Oracle Web Cache to multiple WebLogic Servers to the Oracle Database. It’s a way to uniquely identify a request across tiers.  According to the documentation it’s: The value of the ECID is a unique identifier that can be used to correlate individual events as being part of the same request execution flow. For example, events that are identified as being related to a particular request typically have the same ECID value.  The format of the ECID string itself is determined by an internal mechanism that is subject to change; therefore, you should not have or place any dependencies on that format. The novel idea that I see John had was to extend this concept beyond the diagnostic information that is captured by Fusion Middleware.  Why not also use this identifier in your logs and errors so you can correlate even more information together!  Your logging might already identify the user, so why not identify the request so you filter down even more.  All you need to do inside of WebLogic Server to get ahold of this information is invoke DiagnosticConextHelper: weblogic.diagnostics.context.DiagnosticContextHelper.getContextId() This class has other helpful methods to see other values tracked by the diagnostics framework too.  This way I can see even more detail and get information across tiers. In performance profiling, this can be very handy to track down where time is being spent in code.  I’ve blogged and made videos about this before.  JRockit Flight Recorder can use the WLDF Diagnostic Volume in WLS 10.3.3+ to automatically capture and correlate lots of helpful information for each request without installing any special agents and with the out-of-the-box JRockit and WLS settings!  You can see here how information is displayed in JRockit Flight Recorder about a single request as it calls a Servlet, which calls an EJB, which gets a DB connection, which starts a transaction, etc.  You can get timings around everything and even see the SQL that is used. http://download.oracle.com/docs/cd/E21764_01/web.1111/e13714/using_flightrecorder.htm#WLDFC480 Recent versions of the WLS console also are able to visualize this data too, so it works with other JVMs besides JRockit when you turn on WLDF instrumentation. I wrote a little sample application that verified to myself that the ECID did actually cross JVM boundaries.  I invoked a Servlet in one JVM, which acted as an EJB client to Stateless Session Bean running in another JVM.  Each call returned the same ECID.  You need to turn on WLDF Instrumentation for this to work otherwise the framework returns null.  I’m glad John put me on to this API as I have some interesting ideas on how to correlate some information together.

• Getting Started with NASM

  - by MarkPearl

  Today I got to play with NASM. This is an assembler and disassembler that can be used to write 16-bit, 32-bit & 64-bit programs. Let me say upfront that the last time I looked at assembly code at any depth was when I was studying Computer Science in Pietermaritzburg – ten years ago – and we never ever got to touch any real assembly code so a lot of what I am looking at today is very new to me. The first thing I did was download NASM compiler. This turned out to be a bit more complicated than I thought. Originally I went to http://www.nasm.us/ and downloaded the nasm-2.09.04.zip file which I thought had all I needed. No luck! It seemed to just have the uncompiled code, and from what I could tell I would need to recompile and build it – possibly in c++? Well, I wasn’t going to waste my time with that, so a bit more searching and I found the Win32 (http://www.nasm.us/pub/nasm/releasebuilds/2.09.04/win32/) folder Nasm.exe which I downloaded. Choosing an IDE So, I have NASM compiler but to compile anything you need to pass a string of special characters in the command prompt. That’s fine if I was going to just do one program once every couple of years, but since I am aiming to do quite a bit more exploration of NASM I began searching for an IDE. There were a few options, even apparently Visual Studio with a bit of tweeking could do the job, but from past experience I wanted to avoid the VS route as it can sometimes get confusing. I eventually settled on TextPad which I had used a few years ago for a similar project and it had been simple enough yet powerful enough to do the job. A bit of searching and I found a syntax file for NASM and everything seemed hunky dory. Configuring TextPad to run the NASM Compiler Next was to get TextPad to run the NASM compiler. TextPad has this external tools option that allows one to configure special commands. To simplify the process I first created a bat file in the NASM directory that allowed me to simply compile asm files. The bat file was called as.bat and had just one line of code… nasm -f bin %1.asm -o %1.com -l %1.lst Once I had created as.bat I just needed to go into TextPad and create a tool. I have made a quick video of that just showing you where the various settings are which is viewable below. The 64Bit Problem So I now have an ‘IDE’ linked to my NASM compiler so everything should be fine right? No! Whenever I tried to compile an asm program it compiles fine, but when I try and run it I get an error – “This version of the file is not compatible with the version Windows you’re running. Check your computer’s system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher." Well.. it turns out there are a few complications with having a 64 bit OS! So after searching google and coming to any real solution that I could find other than perhaps attempting to build the code for nasm, I eventually resorted to running a VM with Windows XP on it and putting NASM there… My first hello world program So I attempt my first hello world program as per an example I found… the code was quite simple and is shown below… bits16 org 0x100 jmp main message: db 'Hello World',0ah,0dh,'$' main: mov dx,message mov ah,09 int 21h int 20h Running the build tool from TextPad and everything compiles fine and I now have a console app with helllo world shown. Conclusion It’s very early days with NASM. I have been spoilt with Visual Studio and high order languages so I assume it will be a painful ride getting into the basics of assembly programming but I am hoping that at the end of it, I will at least have a bit more exposure to a language closer to the metal.

• Weird SSIS Configuration Error

  - by Christopher House

  I ran into an interesting SSIS issue that I thought I'd share in hopes that it may save someone from bruising their head after repeatedly banging it on the desk like I did.  I was trying to setup what I believe is referred to as "indirect configuration" in SSIS.  This is where you store your configuration in some repository like a database or a file, then store the location of that repository in an environment variable and use that to configure the connection to your configuration repository.  In my specific situation, I was using a SQL database.  I had this all working, but for reasons I'll not bore you with, I had to move my SSIS development to a new VM last week.  When I got my new VM, I set about creating a new package.  I finished up development on the package and started setting up configuration.  I created an OLE DB connection that pointed to my configuration table then went through the configuration wizard to have the connection string for this connection set through my environment variable.  I then went through the wizard to set another property through a value stored in the configuration table.  When I got to the point where you select the connection, my connection wasn't in the list: As you can see in the screen capture above, the ConfigurationDb connection isn't in the list of available SQL connections in the configuration wizard.  Strange.  I canceled out of the wizard, went to the properties for ConfigurationDb, tested the connection and it was successful.  I went back to the wizard again and this time ConfigurationDb was there.  I completed the wizard then went to test my package.  Unfortunately the package wouldn't run, I got the following error: Unfortunately, googling for this error code didn't help much as none of the results appears related to package configuration.  I did notice that when I went back through the package configuration and tried to edit a previously saved config entry,  I was getting the following error: I checked the connection string I had stored in my environment variable and noticed that indeed, it did not have a provider name.  I didn't recall having included one on my previous VM, but I figured I'd include it just to see what happened.  That made no difference at all.  After a day and a half of trying to figure out what the problem was, I'm pleased to report that through extensive trial and error, I have resolved the error. As it turns out, the person who setup this new VM for me named the server SQLSERVER2008.  This meant my configuration connection string was: Initial Catalog=SSISConfigDb;Data Source=SQLSERVER2008;Integrated Security=SSPI; Just for the heck of it, I tried changing it to: Initial Catalog=SSISConfigDb;Data Source=(local);Integrated Security=SSPI; That did the trick!  As soon as I restarted BIDS, I was able to run the package with no errors at all.  Crazy.  So, the moral of the story is, don't name your server SQLSERVER2008 if you want SSIS configuration to work when using SQL as your config store.

• Creating a new naming context in OUD

  - by Sylvain Duloutre

  A naming context (also known as a directory suffix) is a DN that identifies the top entry in a locally held directory hierarchy. A new naming context can be created using ODSM, the OUD gui admin console, as described in http://docs.oracle.com/cd/E29407_01/admin.111200/e22648/server_config.htm#CBDGCJGF It can also be created using the dsconfig command lione as described below: Creation of a new naming context consists in 3 steps: First create a Local Backend Workflow element (myNewDb in this exemple) ,  responsible for the naming context base dn, e.g o=example. dsconfig create-workflow-element \           --set base-dn:o=example \           --set enabled:true \           --type db-local-backend \           --element-name myNewDb \           --hostname <your host> \           --port <admin port> \           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt Second, create a Workflow element (workFlowForMyNewDb in this exemple) associated with the Local Backend Workflow element. WorkFlow elements are used to route LDAP requests to the appropriate database, based on the target base dn. dsconfig create-workflow \           --set base-dn:o=example \           --set enabled:true \           --set workflow-element:myNewDb \           --type generic \           --workflow-name workFlowForMyNewDb \           --hostname <your host name> \           --port <admin port>\           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt Then, the workflow element must be made visible outside of the directory, i.e added to the internal "routing table". This is done by adding the Workflow to the appropriate Network Group. A Network group  is used to classify incoming client connections and route requests to workflows. dsconfig set-network-group-prop \           --group-name network-group \           --add workflow:workFlowForMyNewDb \           --hostname <your hostname> \           --port <admin port>\           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt At that stage, it is possible to import entries to the new naming context o=example.

• HOWTO Turn off SPARC T4 or Intel AES-NI crypto acceleration.

  - by darrenm

  Since we released hardware crypto acceleration for SPARC T4 and Intel AES-NI support we have had a common question come up: 'How do I test without the hardware crypto acceleration?'. Initially this came up just for development use so developers can do unit testing on a machine that has hardware offload but still cover the code paths for a machine that doesn't (our integration and release testing would run on all supported types of hardware anyway).  I've also seen it asked in a customer context too so that we can show that there is a performance gain from the hardware crypto acceleration, (not just the fact that SPARC T4 much faster performing processor than T3) and measure what it is for their application. With SPARC T2/T3 we could easily disable the hardware crypto offload by running 'cryptoadm disable provider=n2cp/0'.  We can't do that with SPARC T4 or with Intel AES-NI because in both of those classes of processor the encryption doesn't require a device driver instead it is unprivileged user land callable instructions. Turns out there is away to do this by using features of the Solaris runtime loader (ld.so.1). First I need to expose a little bit of implementation detail about how the Solaris Cryptographic Framework is implemented in Solaris 11.  One of the new Solaris 11 features of the linker/loader is the ability to have a single ELF object that has multiple different implementations of the same functions that are selected at runtime based on the capabilities of the machine.  The alternate to this is having the application coded to call getisax() and make the choice itself.  We use this functionality of the linker/loader when we build the userland libraries for the Solaris Cryptographic Framework (specifically libmd.so, and the unfortunately misnamed due to historical reasons libsoftcrypto.so) The Solaris linker/loader allows control of a lot of its functionality via environment variables, we can use that to control the version of the cryptographic functions we run.  To do this we simply export the LD_HWCAP environment variable with values that tell ld.so.1 to not select the HWCAP section matching certain features even if isainfo says they are present.  For SPARC T4 that would be: export LD_HWCAP="-aes -des -md5 -sha256 -sha512 -mont -mpul" and for Intel systems with AES-NI support: export LD_HWCAP="-aes" This will work for consumers of the Solaris Cryptographic Framework that use the Solaris PKCS#11 libraries or use libmd.so interfaces directly.  It also works for the Oracle DB and Java JCE.  However does not work for the default enabled OpenSSL "t4" or "aes-ni" engines (unfortunately) because they do explicit calls to getisax() themselves rather than using multiple ELF cap sections. However we can still use OpenSSL to demonstrate this by explicitly selecting "pkcs11" engine  using only a single process and thread.  $ openssl speed -engine pkcs11 -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 54170.81k 187416.00k 489725.70k 805445.63k 1018880.00k $ LD_HWCAP="-aes" openssl speed -engine pkcs11 -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 29376.37k 58328.13k 79031.55k 86738.26k 89191.77k We can clearly see the difference this makes in the case where AES offload to the SPARC T4 was disabled. The "t4" engine is faster than the pkcs11 one because there is less overhead (again on a SPARC T4-1 using only a single process/thread - using -multi you will get even bigger numbers). $ openssl speed -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 85526.61k 89298.84k 91970.30k 92662.78k 92842.67k Yet another cool feature of the Solaris linker/loader, thanks Rod and Ali. Note these above openssl speed output is not intended to show the actual performance of any particular benchmark just that there is a significant improvement from using hardware acceleration on SPARC T4. For cryptographic performance benchmarks see the http://blogs.oracle.com/BestPerf/ postings.

• EPM 11.1.2.2 Architecture: Financial Performance Management Applications

  - by Marc Schumacher

   Financial Management can be accessed either by a browser based client or by SmartView. Starting from release 11.1.2.2, the Financial Management Windows client does not longer access the Financial Management Consolidation server. All tasks that require an on line connection (e.g. load and extract tasks) can only be done using the web interface. Any client connection initiated by a browser or SmartView is send to the Oracle HTTP server (OHS) first. Based on the path given (e.g. hfmadf, hfmofficeprovider) in the URL, OHS makes a decision to forward this request either to the new Financial Management web application based on the Oracle Application Development Framework (ADF) or to the .NET based application serving SmartView retrievals running on Internet Information Server (IIS). Any requests send to the ADF web interface that need to be processed by the Financial Management application server are send to the IIS using HTTP protocol and will be forwarded further using DCOM to the Financial Management application server. SmartView requests, which are processes by IIS in first row, are forwarded to the Financial Management application server using DCOM as well. The Financial Management Application Server uses OLE DB database connections via native database clients to talk to the Financial Management database schema. Communication between the Financial Management DME Listener, which handles requests from EPMA, and the Financial Management application server is based on DCOM.  Unlike most other components Essbase Analytics Link (EAL) does not have an end user interface. The only user interface is a plug-in for the Essbase Administration Services console, which is used for administration purposes only. End users interact with a Transparent or Replicated Partition that is created in Essbase and populated with data by EAL. The Analytics Link Server deployed on WebLogic communicates through HTTP protocol with the Analytics Link Financial Management Connector that is deployed in IIS on the Financial Management web server. Analytics Link Server interacts with the Data Synchronisation server using the EAL API. The Data Synchronization server acts as a target of a Transparent or Replicated Partition in Essbase and uses a native database client to connect to the Financial Management database. Analytics Link Server uses JDBC to connect to relational repository databases and Essbase JAPI to connect to Essbase.  As most Oracle EPM System products, browser based clients and SmartView can be used to access Planning. The Java based Planning web application is deployed on WebLogic, which is configured behind an Oracle HTTP Server (OHS). Communication between Planning and the Planning RMI Registry Service is done using Java Remote Message Invocation (RMI). Planning uses JDBC to access relational repository databases and talks to Essbase using the CAPI. Be aware of the fact that beside the Planning System database a dedicated database schema is needed for each application that is set up within Planning.  As Planning, Profitability and Cost Management (HPCM) has a pretty simple architecture. Beside the browser based clients and SmartView, a web service consumer can be used as a client too. All clients access the Java based web application deployed on WebLogic through Oracle HHTP Server (OHS). Communication between Profitability and Cost Management and EPMA Web Server is done using HTTP protocol. JDBC is used to access the relational repository databases as well as data sources. Essbase JAPI is utilized to talk to Essbase.  For Strategic Finance, two clients exist, SmartView and a Windows client. While SmartView communicates through the web layer to the Strategic Finance Server, Strategic Finance Windows client makes a direct connection to the Strategic Finance Server using RPC calls. Connections from Strategic Finance Web as well as from Strategic Finance Web Services to the Strategic Finance Server are made using RPC calls too. The Strategic Finance Server uses its own file based data store. JDBC is used to connect to the EPM System Registry from web and application layer.  Disclosure Management has three kinds of clients. While the browser based client and SmartView interact with the Disclosure Management web application directly through Oracle HTTP Server (OHS), Taxonomy Designer does not connect to the Disclosure Management server. Communication to relational repository databases is done via JDBC, to connect to Essbase the Essbase JAPI is utilized.

• NetworkManager Applet shows no networks

  - by Kkelk

  I am "the friend" referred to in the questions here and here. I decided to come and ask a question myself, as I can still not connect to the wireless network. I downloaded Keryx, as suggested here, and managed to download the necessary package and its dependencies. When I attempted to install the packages on Ubuntu using Keryx, Keryx just closed. Following this, I installed the packages manually using dpkg, and as far as I can tell, this was successful: kieran@ubuntu:~$ cd /host/wifi/Keryx/keryx/projects/Kieran/packages kieran@ubuntu:/host/wifi/Keryx/keryx/projects/Kieran/packages$ sudo dpkg -i *.deb [sudo] password for kieran: Selecting previously deselected package bcmwl-kernel-source.
