We recently went from VMS 6.2/Oracle 7.1 to VMS 7.1/Oracle 7.3 on a large VMS cluster.

The performance has gone down by a factor two (approximatively).

We are using the Oracle API to insert incoming data into tables, and the way Oracle gets the job done seems to have fundamentally changed between the two setups:

On VMS 6.2, the process that called the API was the one doing the actual work, and that was done in the VMS supervisor mode.
On VMS 7.1, an additional process is created to do the actual work when the Oracle API is called, and this is done in VMS user mode.

Has anyone else experienced performance drops in a similar upgrade ?

Is it possible to avoid these additional processes ?

Any suggestions ? Received on Fri Nov 06 1998 - 00:00:00 CST
