This is a 'stored statement' from the Global Payroll calculation process,
GPPDPRUN.
It is looking for retroactive changes (new changes that are effective in
previous pay periods).
Was the process run with the 'update stats' option? PS_GP_PYE_STAT_WRK is a
working storage table. It holds the employees to be processed (because
sometimes you only do an incremental paycalc). GPPDPRUN can optionally
issue an ANALYZE TABLE command (PeopleSoft COBOL programs do not use the DDL
models). The option is specified on the second tab of the page where the
operator requests the pay calc process.
I have seen this particular statement become a problem before, it is called
GPPSERV_I_HISTWRK. But the problem is that Oracle is full scanning and hash
joining S and P because it has started with W and then gone to S before it
has gone to P.
My solution was a simple leading hint:
/*+LEADING(WRK P)*/
You could use a stored outline to apply this hint to this statement. There
are no literals inserted into stored statements at runtime, they always use
bind variables. However, the statement is delivered by PeopleSoft in a flat
file that is then loaded into the Stored statement table by their Data Mover
utility. So you can add the hint to the script and reload it. Example
attached, and that is what I normally do.
You could change the Query as Stefane suggested. However, you are changing
a piece of core code. You would have to prove to the project/business that
you haven't changed the functionality. It is easier to do that when you are
only adding a hint.
Because this is vanilla code, PeopleSoft could deliver a new version in a
patch or upgrade. Checking for differences in delivered and current
versions of stored statements needs to be added to the usual compare
procedures.
How many employees are you paying per pay period. How many pay periods have
you got?
(SELECT cal_run_id, count(*), count(distinct emplid) from ps_gp_pye_seg_stat
group by cal_run_id)
Are you running multiple concurrent payroll calculation processes?
PeopleSoft call this 'streamed payroll processing'.
