OBIEE comes with a very useful usage tracking feature. For information about it and how to set it up see these links: http://obiee101.blogspot.com/2008/08/obiee-setting-up-usage-tracking.html http://www.oracle.com/technology/obe/obe_bi/bi_ee_1013/usage_tracking/usage_tracking.htm http://108obiee.blogspot.com/2009/07/obiee-usage-tracking-setup-and-cloning.html Usage Tracking captures the logical SQL of queries in a column called QUERY_TEXT in the table S_NQ_ACCT. However, out of the box this column is defined as 1k (1024 bytes) long. In some situations this will limit its usefulness because the text will be truncated if necessary when it’s inserted.

This is a supplemental post to this one describing how to set up a VUser in LoadRunner to test OBIEE. It’s various notes that I made during the development but which aren’t directly part of the step-by-step tutorial. They’re not necessarily vital for recording scripts, but observations and explanations that should be helpful when working with LoadRunner and OBIEE. Validation using sawserver logs It’s no use running a load test if the load you think you’re applying isn’t actually being applied.

My two earlier posts (here and here) detail the difficulties I had with LoadRunner (now called HP Performance Center). After a bit of a break along with encouragement from knowing that it must be possible because it’s how Oracle generates their OBIEE benchmarks I’ve now got something working. I also got a useful doc from Oracle support which outlines pretty much what I’ve done here too. In essence what you do - and what the Metalink document 496417.

A new blog from James Morle, who I don’t know but from other bloggers sounds well respected, and describes himself thus: Since it’s been nearly ten years since I wrote my book, Scaling Oracle8i, I thought it was about time that I started writing again. I thought I would start with the new-fangled blogging thing, and see where it takes me. Here goes. He’s got a really interesting post on “red flags” to look for in diagnosing performance problems in Oracle: Spotting the Red Flags (Part 1 of n).

Bit of an odd one this. Oracle 11g database, a user’s password has expired. But when I try to change it, I can’t: [sourcecode language=“bash”] $sqlplus MYUSER/oldPW@oraDBServer SQL*Plus: Release 10.2.0.1.0 - Production on Wed Sep 23 07:57:41 2009 Copyright (c) 1982, 2005, Oracle.

(Updated 12th Oct 09) Here’s a list of the OBIEE benchmark documents published by Oracle: BenchmarkDateSource document1 - IBM System x3755Sep-07PDF2 - HP DL380 G4Sep-07PDF3 - Sun T2000Sep-07PDF4 - Sun SPARC Enterprise T5440Aug-09PDF5 - Sun SPARC Enterprise T5440Oct-09PDF Collecting the numbers into one table gives this: Based on the details in the documents I think these were all against OBIA’s Service Analytics schema & dashboards/reports. Interesting to note the side-by-side comparison in benchmark 3 (Sun T2000) of two servers, in one case both running BI and Presentation Services and in the other having the two components separate.

Production cluster is 2x BI Server and 2x Presentation Services, with a BIG-IP F5 load balancer on the front. Symptoms Users started reporting slow login times to BI. Our monitoring tool (Openview) reported that “BIServer01 may be down. Failed to contact it using ping.”. BIServer01 cannot be reached by ping or ssh from Windows network. Diagnostics nqsserver and nqsclustercontroller on BIServer01 was logging these repeated errors: [nQSError: 12002] Socket communication error at call=send: (Number=9) Bad file number

A new version of the web browser Opera was released recently. Several years ago I used Opera and may even have paid for it IIRC. Then Firefox came along, and the “it’s not IE” excuse was lost for Opera. Not that I mind IE too much nowadays but at the time it was atrocious. Since then I’ve revisited Opera each time a new release has come out, but nothing has impressed me enough to ditch Firefox (and nowadays Google Chrome).

Bringing together in one place all of the script syntax that I’ve found so far for using with OBIEE’s AdminTool.exe /command Details and examples on usage in the following blogs (where I compiled the commands from): Venkat Erik Eckhardt (translated from Czech, original here) @lex Kumar Kambam DON’T TRY THIS AT HOME! I would only recommend this for read-only purposes such as generating the metadata dictionary or consistency check. * OpenOnline DSN [user [password]] - Opens the online repository.

There’s an undocumented feature in AdminTool.exe that you can use the /command switch with a text file containing scripted commands to make changes to an RPD file (or create a new one). It’s undocumented and UNSUPPORTED so be careful using it. Some good details in these blog posts, especially Erik’s which has a good list of syntax. Venkat Erik Eckhardt (translated from Czech, original here) @lex Kumar Kambam I’m intrigued to know how the original posters figured out the commands available, if it’s undocumented… :)

Kudos to the My Oracle Support blog for taking the time to respond to my to my comment about searching for Metalink 3 SRs throwing an error. In essence, if you previously used Metalink 3 you must use https://support.oracle.com. If you use https://metalink.oracle.com/ then you’ll hit the problems I did. ML3 SR’s are not supported on https://metalink.oracle.com/CSP/ui/index.html. This front end is used for support on legacy server technology, middleware including BEA, and EBusinessSuite

Another way of keeping up with what’s going on in the obiee world, add this RSS feed of del.icio.us obiee tags to your reader. It may be less “current” (because people might discover and bookmark ‘old’ pages), but it’s another tool in the armoury :) If you want an aggregated RSS feed of OBIEE / Oracle related blog postings try this one.

Following the Oracle CAF tutorial here, I got to Cloning Answers Requests section and then got stuck. I’d set up my environment exactly the same as in the tutorial, down to the same paths etc. After firing up the CAF to clone requests from the SampleSales catalog: I clicked on Next and got the error “Exception occurred when while initializing repository!!!” By playing around with the passwords and path names I determined that both RPD files existed and that CAF could load them enough to validate the passwords.

This weekend just gone Metalink3 went to the digital dustbin. In principle this is a Good Thing, as multiple support websites for a single company is confusing and frustrating. Metalink is now “My Oracle Support” and is a flash-based whizz-bang affair. Everyone has different tastes, but there’s a lot to be said for plain HTML for ease and speed of access. But then people probably grumbled to the Wright Brothers that there was nothing wrong with land-transport at the time…

Introduction In this article I plan to get samplesales and paint repositories hosted on a single server, using one BI Server instance and two Presentation Services instances. This is on both Unix (OEL 4) and Windows, and both OC4J (OBIEE’s “basic installation” option) and OAS (“Advanced Installation”). Both samplesales and paint are shipped with 10.1.3.4 of OBIEE, you’ll find them in $OracleBI/OracleBI/server/Sample. This article assumes you’ve got the RPD of each into $OracleBI/OracleBI/server/Repository and unpacked the web cats for each into $OracleBIdata/web/catalog.

For some reason Oracle haven’t put out a 10.x version of the error & message codes reference guide for OBIEE, but the previous version for Siebel Analytics is still useful: PDF version: http://download.oracle.com/otndocs/products/bi/bi-ee/docs/784/AnyMsg.pdf HTML version: http://download.oracle.com/docs/cd/E12103_01/books/AnyMsg/AnyMsg_Messages.html#wp1007961

xkcd.com is one of my favourite comics on the web. It strikes just the right balance of geeky witty humour without being too smart-ass. I liked this recent one a lot :-) A couple of other favourites: http://xkcd.com/149/ http://xkcd.com/327/ http://xkcd.com/123/
