-It IS advisable to use lazy swap.
-No problems specifically related to Oracle or SAP.
-No performance gain.
-One downside to lazy swap:
It allows a dead lock situation where a process needs page/swap space and
there isn't any. The system will prevent the dead lock from occuring by
killing processes until there is sufficient page/swap space. It seems to
prefer idle processes, but in extreme cases will take whatever it can find.
It ignores little. This will likely cause very mysterious symptoms which
will
be hard to diagnose. E.g. you try to run a big oracle job, and a few minutes
or hours later cron dies or inetd dies, or nfs dies, or a completely
unrelated oracle job dies.
Ciao,
