Solaris 8
MQ 5.3
Weblogic 6.1
4GB of RAM E450
Iplanet 6x sp6
Has anyone seen these kind of Err#62. I saw lots of postings on
the Web, with no clear suggestions. Below are the current kernel
settings per MQ requirements.
My plan of action is to force the latest SUN patches in
particular the Kernel Path. Increase the Semaphores... stop all
other (Weblogic, Iplanet) and see if I can get MQ working. But
if anyone one has any good suggestions... I'll take them!
Creating the Queue Manages just hangs with Err#62 and lwp_
warnings:
