PeopleTools version:Tools: 8.48.09



OS/RDBMS Version*( required for Tools Forums): Oracle 10.2.0.4

Application type and version:

Description of the Problem/Question:


Customer currently testing a process which exposes XML publisher functionality via self service. The process calls an app engine which
generates an XML file, processed by XML Publisher, and then displayed in the browser window.

They have found that any more than ten or so users in our test environment (two app servers, one web server per app server) seems to slow
the process to a halt, even causing some requests to go unprocessed. The bottleneck seems to be at the web server (WebLogic) as the
database and app server performance metrics are very good, however PeopleSoft Ping suggests that the web server is having trouble.

production environment has 8 app servers, one web server per app server. Are there any configuration changes we can make to improve
the serving of PDFs from XML publisher output? Add more web servers per app server? WebLogic java VM heap settings?


WebLogic Server 8.1 SP5

Tuxedo: Version 8.1, 64-bit, Patch Level 192


Any other thoughts on performance degrade with XML Publisher with more than 10 users.

Are there any configuration changes we can make to improve the serving of PDFs from XML publisher output? Add more web servers per app server?



Thanks
