if you are trusting of the auto memory management stuff, the streams pool is 
now self adjusting in 10gR2, so that you shouldn't see these kind of errors.  
It *should* borrow memory from other pools to satisfy these moments of 
increased use during PQ operations.

Hi!
we introduce it in our technology arsenal with 10g version
Actually we're quite happy with it, but sometimes we experience such 
error as:

ORA-10388: parallel query server interrupt (failure)
ORA-12801: error signaled in parallel query server P000
ORA-04031: unable to allocate 312 bytes of shared memory ("streams 
pool","unknown object","apply shared t","knalf:KGGHSTCLN")

Previously we simply resize streams pool to 260M, but is it the only solution 
to this problem?
