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/

UPDATED: See a HOWTO for OBIEE and LoadRunner here: /2009/10/01/performance-testing-obiee-using-hp-performance-center-a.k.a.-loadrunner/ This is following on from my first post about OBIEE and LoadRunner, in which I failed dismally to get a simple session replaying. In a nutshell where I’d got to was using the “Web (Click and Script)” function which worked fine for logging in but when running a report resulted in an error on the rendered page. Digging around showed the error was from the javascript of the OBIEE front end.

A question that pops up on the OBIEE OTN forum quite often is how to use non-Oracle databases like MS SQL Server when the OBIEE server is running on a non-Windows OS such as Linux. The answer in a nutshell is that since version 10.1.3.3.1 OBIEE has been bundled with ODBC drivers for unix/linux from a company called DataDirect. See the release notes here for more information and installation instructions (as well as a list of support databases).

A follow up to my previous post about Metalink’s “Do you mean” feature, this one made me laugh: I shall miss this kind of thing when Metalink3 merges into My Oracle Support…. Meep meep!

As well as tinkering with the sawserver (Presentation Services) logging level and format, we can specific which bits of the log we’re interested in. This is useful for two reasons: We can enable detailed logging for a specific area, without impacting performance as much as detailed logging throughout would cause By only logging in detail the area of interest we can more easily read the log output and not have to wade through pages of irrelevant information Chapter 9 (“Using the Oracle BI Presentation Services Logging Facility”) of the Presentation Services Administration Guide details the log configuration.

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.
