UPDATED: See a HOWTO for OBIEE and LoadRunner here Introduction LoadRunner is a tool from HP (bought from Mercury) that can be used to simulate user activity. It supports a whole host of protocols but for OBIEE I’m obviously using the Web one. There are two flavours, “Web (Click and Script)” and “Web (HTTP/HTML)”. The latter simply shoves HTTP requests at the server, whereas “Click and Script” simulates mouse and keyboard entry and thus is more appropriate for this user-based application.

I posted a while ago about the sawserver (Presentation Services) log configuration file. Today I’m doing some work digging around why sawserver’s throwing an error and so increased the log detail. This parameter is really helpful to use: fmtName=“short” Consider in these two screenshots, the first is with the default log format and shows about six entries. The second is short log format and is about ten times as much data.

I have a couple of OTN forums bookmarked, and found that generally every few hours I get signed out and end up viewing them as Guest. I then have to click on sign in, enter password, etc. (Signing out this frequently is ridiculous, IMHO). I found that instead of using the direct URL of a forum, eg: http://forums.oracle.com/forums/forum.jspa?forumID=378 if I use this form: http://forums.oracle.com/forums/adfAuthentication?success_url=/forum.jspa?forumID=378 then I end up signed in more often, and if I’ve been signed out then it goes straight to the login page and then through to the forum.

Here’s a set of scripts that I use on our servers as a quick way to check if the various BI components are up and running. Because we split the stack across servers, there are different scripts called in combination. On our dev boxes we have everything and so the script calls all three sub-scripts, whereas on Production each server will run one of: BI Server Presentation Server & OAS Informatica & DAC The scripts source another script called process_check.

We’re upgrading from OBIA 7.9.5 (Financials - GL) to OBIA 7.9.6. Our reasons are for support (7.9.5 does not support Oracle 11g) and minor functionality additions. Our architecture is: HP-UX 64 bit Itanium (11.31), Oracle 11g (11.1.0.7), separate ETL server, 4x OBIEE servers (2x BI, 2xPS). We have no customisations in the ETL except something for budgets, which is superseded in 7.9.6. This post is a semi-formed articulation of my frustrations encountered during an initial run through of the upgrade in a sandbox.

I keep hitting this error when setting up OBIA. I suppose it’s what it says on the tin, but Googling it didn’t match so I’m posting this so next time I hit it I remember :-) Repository Error ([REP_51821] Failed to connect from Integration Service (pmserver) to repository Oracle_BI_DW_Base running in exclusive mode.) The cause is the Repository Service having OperatingMode set to Exclusive. This is necessary for some of the setup operations like restoring the pre-built Repository, but if you forget to switch it back the Integration Service will suddenly stop working.

I successfully installed OAS 10.1.3.3 and patched to 10.1.3.4. http://localhost:7777 gave the OAS welcome page, but going to http://localhost:7777/em gave 404 Not Found. In [OASHome]/j2ee/home/config/servers.xml search for ascontrol, you should get: change the start attribute to true Restart OAS ([OAShome]/opmn/bin/opmnctl restartproc) and Enterprise Manager should now be available

There’s been a bit of hype about Bing recently, so I thought I’d try it out in trying to get to the bottom of this question on the OBIEE forum. The question was around the nqschangepassword utility and the error it’s reporting: nQSError: 46090 The odbc.ini file could not found or could not be accessed. I did a google for the error to see what other issues could cause the error.

I’m starting on an upgrade from OBIA 7.9.5 to 7.9.6 and wading through the two main docs: 7.9.6 Upgrade guide 7.9.6 Installation guide It would be nice if Oracle could come up with some less confusing terminology. It seems that not only is the whole product of OBIA referred to as OBIA (see @lex’s posting for a good explanation), but that the sub-components which are not-OBIEE-or-DAC-or-Informatica is also OBIA, c.f. page 6-1 of the Upgrade guide “[…]upgrade your Oracle BI Applications environment to the current version.

Very good post by @lex giving a nice clear explanation of what OBIA (Oracle Business Intelligence Applications) is http://siebel-essentials.blogspot.com/2009/06/can-you-describe-oracle-bi-applications.html This should be made a sticky on the OBIA forum in my opinion. It’s clear from postings on the forum that an awful lot of people don’t understand what OBIA is or how it sits with OBIEE. I even attended a course last week in which the Oracle trainer stated that OBIEE included ETL and DW schemas, and stuck to this when challenged.

OBIEE’s Systems Management component exposes configuration and performance data through Java MBeans. As discussed in other posts these can be be accessed through several different ways: JConsole (see also here) oc4j Windows PerfMon (although I guess this isn’t actually using MBeans/JMX?) saw.dll?perfmon BI Management Pack Since it’s a standard java technology being used we can in theory use anything that is designed for monitoring mbeans via jmx. Doing some Googling I discovered jManage.

If, for some reason, you need to check what web application server is in use for Presentation Services (as this chap needed to), you can use an add-in for FireFox called HttpFox to inspect the HTTP headers. 1. Install HttpFox (and obviously Firefox if you don’t have it already!) 2. Open the HttpFox window (Tools -> HttpFox -> Toggle HttpFox) 3. Click the Start button in the HttpFox window 4. Navigate to your OBIEE home page

I found this post very interesting: Paul Graham : Maker’s Schedule, Manager’s Schedule (originally found here) It was one of those mini-revelations when I found something that greatly resonated and explained an inexplicable frustration I find in the workplace sometimes. I wonder how applicable it can be to a large corporation though, rather than a start-up where it’s given that people are allowed to be bolshy with their meetings? ;-)

We routinely change Oracle passwords as part of security best-practice, I keep hitting this and keep forgetting why! :-) [sourcecode language=‘sql’] ALTER USER DAC_REPO IDENTIFIED BY 1KoBe3RH REPLACE YlR94tqp [/sourcecode] Error report: SQL Error: ORA-00922: missing or invalid option 00922. 00000 - “missing or invalid option” *Cause: *Action: Someone better qualified than me can explain why but I suspect it’s the leading number in the new password. Quoting the passwords then works fine:

One of my little gripes with Metalink is its purporting to be helpful when it’s blatantly not. Here’s one: Now which is more likely, on Metalink 3; that I’m searching for sawserver (integral component to OBIEE), or sqlserver?!

Yet another way to access the BI Management data discussed here - through Windows’ PerfMon tool. This will only work for installations where your OBIEE server is running on Windows. You should be able to run PerfMon locally or remotely. Standard practise would be not to run it locally on a Production machine :-) To run PerfMon go to Start->Run and enter perfmon, or navigate Start -> Settings -> Control Panel -> Administrative Tools -> Performance

Mark Rittman has an excellent article about querying the DAC repository database tables, including a downloadable RPD file. Being new to working with RPDs I thought it would be good practise to explore this as well as hopefully get some useful information about our current ETL deployment. I downloaded the RPD to c:\OracleBI\server\Repository and opened it up in the Admin tool (Administrator/Administrator). First off I changed the connection pool to point to my DAC repository database, having setup a TNS entry for it first.

Our main servers are Unix and I’m as happy as a pig in muck at the command line, so when I’m working on Windows (where I’ve got a test OBIEE install) I like to stick with the CLI where possible. PSService is one of those tools that I instinctively reach for without realising it. Combined with Launchy, it’s even better. Simply put, you can control windows services from the command line.

By a strange co-incidence after following this thread on OTN forums about a BI crash and struggling to understand the actual problem, I think I’ve encountered it myself! I’ve got a test install of OBIEE running on my Windows XP laptop, and whilst building a report in Answers got this: ](http://2.bp.blogspot.com/_RCx_EVJpczQ/SmiDrEorbbI/AAAAAAAAGcg/OPGwTLXXg8k/s1600/crash1.png)[ was: szAppName : sawserver.exe szAppVer : 10.1.3.4 szModName : kernel32.dll szModVer : 5.1.2600.3119 offset : 000097a3 Going to the sawserver log at c:\OracleBIData\web\log\sawlog0.

The configuration of how Presentation Services (sawserver) does its logging is in the file web/config/logconfig.xml (same directory as instanceconfig.xml). It’s all nice and XML’d: Logging Detail Change the numerical values in the FilterRecord entries to alter the detail level of the logging. Lower means less detail, higher means more. Be aware that your log files can grow very rapidly if you set the logging too high, and unless you’re troubleshooting then leave them at the defaults.
