For my Oracle images, I do the following:
joe /etc/profile.local
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u16384 -u 65536

I am building virtual servers to run Websphere MQ broker.
I had to set various kernel parameters (including setting fs.file-max =
32768)
I am confused by some of the doc I received from the MQ folks- see
below:
* "Set ulimit to 4096. When dealing with large numbers of open
sockets (a single socket per concurrent connection) the operating system
may limit the number of files that a single process can open at one
time. On UNIX, the limit for the number of files that a process can open
also applies to sockets, and therefore you need to increase the maximum
open file handles setting to reflect the expected number of concurrent
connections"
The ulimit command has lots of options.
How can I determine what the defaults are (look at
/etc/security/limits.conf? or a ulimit option?)
How do I set ulimit for the id mqm if needed?
