RE: "row cache lock" waits on INSERT

Abdul,

When you see the wait happening, what is being reported in P1, P2, P3?

Take the P1 value and do:
Select * from v$rowcache where cache#=<value of P1 when session waits on 'row cache lock' wait>;

Hope that helps,

-Mark

Subject: "row cache lock" waits on INSERT

We are seeing lots of "row cache lock" waits in the DB during a long running insert and the performance is really poor on this insert. Any suggestions on what to look for? We have not come up with much from Metlink/Oracle Support/Google yet.

Environment: 3-node Oracle RAC (10.2.0.3.0 on Solaris 10 w/ ASM).

Thanks,
Abdul
