I should have mentioned. It is 64 bit AIX, the limits have been checked again and again.
The total pga for this process is 358M and there is 6M free in various heaps.
The sort subheap error comes while the impdp process is creating the indexes.
I analyzed the heap dump of the sort subheap error.
Since I have no direct access I cannot check things myself easily.
Hopefully the dba’s can generate the kxs-heap heapdump today.

Regards Hans-Peter

I thought, I replied to your comment, Sorry. Yep, ORA-4031 is for shared pool heap and ORA-4030 is pga heap. Unless, shared server or MTS is in use, they don’t mix up ( I think).
Some of the basic things you might want to check is :
1. Is this 32 bit software? Is your SGA+PGA exceeds 32 bit boundaries?
2. Is there any limits check ulimit?
3. Is pga_target too small for the workload? any other underscore parameters limiting? Anything in v$pgastat?

Of course, correct thing to do is errorstack and heapdump and analyze those trace files.

Cheers
Riyaj

You can skip my previous post.
I mixed up the sga and the pga.
I am currently investigating a problem with impdp which gives ORA-04030′s at different stages of the import.
We have ORA-04030 with the (sort subheap,sort key) arguments.
The sort subheap part is full with about 1200 piece marked perm and has only 6k left whereas it wants to allocte 64k. There is enough free and freeable space in other subheaps though.
The other is ORA-04030 with (kxs-heap-c,kghsseg: qcstxsInit)
Don’t have a heap dump of it yet.
Do you have any advice.

Regards Hans-Peter

Could this behavior also lead to ORA-4030′s?
According to Dion Cho on http://dioncho.wordpress.com/2009/07/27/playing-with-ora-4030-error/
ORA-4030 can also occur because of pl/sql issues.

Hans-Peter

Thanks for reading my blog.

“enqueue_resources” had sudden outburst of growth.

Client found an unfortunate code issue, that may have caused the problem growth. Client has fixed that part of their code for now. But, point is that this issue can happen in any instance and for a completely different reason.

Cheers
