Re: System API reference

I'm not aware of an easy way to know this - most stuff in Work Management 
is at the pool level. There is a temporary storage attribute for jobs that 
you can get with RTVJOBA in CL, QUSRJOBI in an API, but that is for disk, IIRC.

May I ask - are you using dynamic tuning? The QPFRADJ system value controls 
this. You might try running things with this on, then see how large the 
private pool (shared pool?) gets, then turn off tuning and make your 
adjustments yourself.

Another issue might be the use of expert cache - the pool must have the 
paging option set to *CALC, which normally means the pool must be a shared 
pool, to use expert cache. *BASE is usually *CALC, so the page sizes can be 
larger, which can greatly affect the speed of your applications. There is 
also an API that can set any pool to *CALC - Change Pool Tuning Information 
(QWCCHGTN) - even fixed pools.

The tuners (Help Systems AutoTune, QPFRADJ, etc.) use various WRKSYSSTS 
info to decide when to change pool sizes. As far as I know, they don't go 
to the job level. There is a Retrieve System Status (QWCRSSTS) API that can 
get you that stuff, but why reinvent the wheel?
