(Doc ID 1530065.1)

Last updated on MARCH 30, 2016

Applies to:

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

Symptoms

When using stateful failover (with Coherence*Web or WebLogic Cluster), the following errors are seen in the WebLogic logs (PIA_stderr.log for Unix/Linux and NTService log for Windows)

 
In PeoplTools 8.52, the error occurs only for certain functionality such as charting functionality and file attachments.  The user experience varies depending on what functionality they are using. For example, if attempting to display a PeopleSoft Ping Chart, the image is missing.

In PeopleTools 8.53, the error occurs immediately at signon, resulting in user being unable to successfully sign in and access the PeopleSoft application.
