E-AE: Performance Degradation When Using Do Loop Action to Process Large Amount of Data on PT 8.52 & PT 8.53

(Doc ID 1640355.1)

Last updated on NOVEMBER 09, 2015

Applies to:

PeopleSoft Enterprise PT PeopleTools - Version 8.52 to 8.53 [Release 8.4]
Information in this document applies to any platform.


PeopleTools 8.52 or 8.53

After upgrade to PT 8.52/8.53, Application Engine (AE)  program with Do Select/Do Until/Do When Actions procsessing large amount of data takes a much longer time than before PeopleTools upgrade e.g. running in old PeopleTools 8.50.

The generated AET Timing Report, showed most time is NOT spent on Peoplecode and SQL.  There is a big gap showing in the total timing in summary,


Replication steps:

1. Set AE trace=128 in process definition or psprcs.cfg.

Parameter List         Append              -TRACE 128




2. Run Application Engine program with Do Select/Do Until/Do When Action, such as  FS_JGEN in a FSCM 9.1 environment or SES search indexes build programs.

3. Check .aet file generated.

The following is the timing information from a test run,  AE_FS_JGEN_.AET.

SQL, cache and Peoplecode take only about 20% total run time and the rest is the lost to other unclear events.
