Can somebody tell me what storage pool is used for PASE jobs?

A three sentence description of i5/OS PASE: i5/OS PASE loads an AIX-format
program into a process-local address space (based on i5/OS teraspace
support), flips the processor into AIX/"pointer tags inactive" mode and lets
the program run. AIX-format programs request operating system services via
"system calls" (or "syscall" for short). i5/OS PASE intercepts these
syscalls, translates them into an equivalent i5/OS call and translates any
returned information back into an AIX-equivalent format on return.

So, via this i5/OS PASE "syscall glue" layer, i5/OS PASE programs end up
using i5/OS operating services for jobs/processes, memory management, file
systems, sockets, userids, configuration, authorization, auditing, etc.

i5/OS PASE programs generally run in the same job that calls them or as a
new job in the same subsystem as the program that started them. The same
i5/OS performance "knobs and levers" you are familiar with will change the
performance of jobs making use of i5/OS PASE too.

As was mentioned in other replies, there is a newsgroup dedicated to i5/OS
PASE that members of the i5/OS PASE development team actively monitor:


But since the original question seems to be specific to PHP performance, the
Zend specific support may be a better fit. I found this Zend knowledgebase
item that might help:

or Zend's forums (there are several dedicated to i5/OS):

Hope this helps.
