Baan Oracle* Driver Performance Problems
Upgraded database from 7.3.4 to 126.96.36.199 and didn't seem to observe any performance problems.(The Baan4c binaries reside on an NFS server mounted across to 5
The Baan Oracle8 driver was then utilised and performance took a nose dive (from the users perspective, as the database wasn't overworked nor are the servers).
From trussing the Baan Oracle8 driver process we could see it constantly accessing the oraus.msb message file. This behaviour is described in the Oracle bug
2142623 but I don't believe we are hitting this bug (neither do Oracle Support) as we cannot reproduce in other Application environments nor even reproduce as per
the bug report analysis.
I believe the Baan Oracle8 driver is some how mimicking the same behaviour as the bug.
Reverting back to the Baan Oracle7 driver resolved the constant oraus.msb file access but Baan do not support this configuration with an Oracle8 database.
The question is...........
Has anybody upgrading to the Baan Oracle8 driver (utilsing Oracle 8.1.7) and had performance problems our even a success.
If you have implemented this type of upgrade then could you please inform me of the exact version of Baan, porting set utilised etc.
Any thoughts would be appreciated.
