JES (Mail, Directory, Calendar) on Red Hat w/ Sun's x4200
By jhawk on Oct 12, 2006
I was in Boulder, Colorado this week. We were setting up a demo on how the Sun Java(tm) Messaging Server 6.2 could provide storage for Voice Mail. One interesting requirement was that the customer required support for Red Hat Rel 4 Linux. Personally, I've never before tried to install our product on Linux till now.. In this case, we were installing on a Sun x4200 Box.
Some of the few configuration issues we worked around.
Temporary File System
The Java(tm) Enterprise System (JES) installer requires that /tmp and /var/tmp must be on different file systems. Some people like to just place a link from /var/tmp to /tmp, this causes all sorts of problems. The JES installer will try to create a link within a link.
File Descriptor Limits
The only problem is this,
we need to set the ( ulimit ) value by using /sbin/sysctl because ulimit on Linux is a shell dependent variable, the value of ulimit
might be gone once you come out of the shell. Change to bash shell and then set ulimit -n 20480 and restart the server
