F5 BigIP LTM Web Accelerator RamCache interferes with Oracle EnterpriseOne 8.11
Dec 17th, 2009 by Mr. Blue

For anyone trying to implement Oracle EnterpriseOne on F5 BigIP LTM with Web Accelerator module; and although it’s mostly not recommended by F5 to do this, you’ll need an iRule to make E1 8.11 to work with Web Accelerator.

With RamCache enabled (as is required for Web Accelerator to function), some of the content in the dynamic .maf files served by EnterpriseOne gets cached and held in RamCache; it seems for some reason (and it still may be my ‘greenness’ to the F5 WebAccel) that this data is not getting moved from Hot Cache to Smart Cache, as after a few logins, causes some users to experience session re-use from other users. Very bad!

It seems that no matter what I tried to do to exclude/proxy only the .maf files in WA, they keep getting caught in RamCache (Hot Cache) and held for way too long.

In order to stop this behaviour, just use an iRule to disable cache for .maf file requests:

when HTTP_REQUEST {
if { [HTTP::uri] contains “.maf” } {
CACHE::disable
}}

That’s that! Use the F5-provided WA policy for Oracle EnterpriseOne ERP and you’re set!
If anyone has happened to know of another way to deal with this or has managed to use WA on E1 8.11 WITHOUT having to do this, I am all ears… show me how it’s done!
