Oracle on IA64 uses 10x more memory than PA-RISC

Re: Oracle on IA64 uses 10x more memory than PA-RISC

The only other significant thing I noticed is that the Oracle DB internal JVM on IA64 seemed to have worse leaks. The worst PGAs were the ones using XML Parsers, so I modified these programs to restart periodically.

We do see significantly less memory use after 9206, so I'm not sure why you're still seeing problems. I'll try to do some diags tomorrow and post it here.

Duncan,
There is no mention of the change in apparent stack VM size in the official documentation. It seems that the difference was expected to be too subtle to notice. Of course, folks looking at ps vsz or other VM size metrics do tend to notice it.
