Websphere : Web Server Plug-In Retry Interval
When stopping and restarting application servers, it is important to consider the correlation with the Web server plug-in retry interval. This is especially important in an environment with only a few application servers. You need to understand the rate between starting and stopping application servers in a cluster and the retry interval so that you do not get HTTP request failures when you stop application servers in a cluster.

Websphere 6.1 Network Deployment RHEL 5.x – Silent Install
Check if previous version installed by root
If WAS was previously installed as root, it would have created the temp dir /tmp/niflogs, owned by root. When you install as was61, it needs to write to this dir, so remember to chown / chmod this dir, or the install will fail in a very obscure way.
Difference between IBM & SUN JVM/ Porting J2EE applications
IBM’s JVM is written to meet the specs as documented by Sun. IBM runs the test suit against their JVM to make sure that what should occur does occur. They (IBM) feel that their code performs the requested functions more efficiently and thus performs better while still providing the same results. IBM may throw one error exception while Sun’s may throw another.
