Bull/IBM pSeries with AIX 4.3.3

General Information

WebLogic Server will end support for Bull/IBM pSeries with AIX 4.3.3 starting December 31, 2003. For information, see WebLogic Server and WebLogic jDriver End-of-Life Announcements.
To download supported releases for this platform, see Download WebLogic Server for Your Platform.
AIX is Bull/IBM's version of UNIX for pSeries servers. For information on AIX, go to IBM's website.
Get the JDK for AIX 4.3.3 and the latest JDK patch from the IBM Java Technology web page.
UDP_SENDSPACE buffer size defaults to 9216 (9k). WebLogic Server sends fragments up to 32K. Using a buffer size smaller than 32k may cause an IO Exception. Users should set the buffer size to 32 k. Use the following command:

The StartWeblogic.sh script. exports LIB_PATH instead of LIBPATH. Users should update the script by replacing export LIB_PATH with export LIBPATH as shown below:

There are some known issues in using RMI-IIOP with WebLogic 5.1 with JDK 1.2.2.11 as the RMI-IIOP implementation relies on some JDK specific features. BEA addressed these in subsequent releases of Weblogic.
On AIX, the WebLogic-to-Netscape-Enterprise-Server Bridge (NSAPI) used to synchronize communications from the proxy to the WebLogic Server to avoid problems encountered with these products on AIX. As a result NSAPI on AIX was single-threaded, allowing just one access at a time.
These problems have been solved with Service Pack 8 for WebLogic 5.1—if you have installed the latest service pack, the NSAPI plug-in is no longer single-threaded.
IBM highly recommends installing the following APAR's (patches) for AIX users with JDK 1.3.0 that are experiencing memory corruption problem:
APAR IY27684 (kernel fix)
IY27836 (malloc fix).
These, along with Java APAR IY28205(JDK130 PTF 9b), solve issues that required the use of -Xgcthreads.
