I have successfully installed Tuxedo,PeopleTool(64-bit ) and Weblogic(32-bit Generic jar, since Weblogic 64-bit is not available and could manage with generic jar) on Windows Server 64-bit. While installing PIA I could assign the directory where weblogic is installed at this point it's triggering a warning message that PIA requires 64-bit weblogic (I could move further despite the warning message and I am sure a generic jar version of weblogic can replenish the absence of 64-bit), whereas at the end of the installation it shows an error as PIA installation failed and the log file produced the following comments
From edlivery.oracle.com, Peopletools 8.52 folder, you should download :
JRockit JDK R28.1 for Java SE 6 with JRockit Mission Control 4.0.1 for Microsoft Windows (64-bit x86)
Tuxedo 10gR3 for MS Windows Server 2008 w/MS VS 2008 x86 32-bit
Oracle WebLogic Server 11gR1 (10.3.4) Generic and Coherence
Do you have some more input under webserv directory ? There should be a log file.
How did you created the PIA ? Which user is in used ?
Please give us more details.
