Hi everyone,=20
9204, Windows 2003 Enterprise
ORA-04030: out of process memory when trying to allocate 49676 bytes (hash-join subh,kllcqas:kllsltba)
What fun. Yes, I know this means it is out of memory. I know that hash joins are memory-intensive. I want to allow the db to utilize more memory. Using hash joins speeds up the data loads.
I have pga_aggregate_target set to 900m (due to a bug). I decreased the amount of memory allocated to the sga and the db block buffers as indicated in note 116076.1. Yes I know it's about NT, but I'm grasping here.=20
I watched the memory allocation ramp up on the server while Informatica was running. It gets to around 2.1, 2.2 gb and doesn't go any farther. Jobs begin failing.=20
Our sysadmin says there's no problem with w2003E addressing more than 2GB contiguous memory, like the note says. However, the behavior was pretty suspect. =20
Any windows people that can point me in the right direction? =20
This was brought on by setting the optimizer_goal for this user to choose. We set it back to first_rows and this error does not occur. This makes sense to me, however I really want to see the db use available resources instead of barf.
