RHEL 3
try to upgrade linux to RHEL 4
set INFORMIXSERVER to shared memory connect
after run 'oninit -ivy'
It won't create all the system database and display error message :
25588: The appl process cannot connect to OnLine server

If I set INFORMIXSERVER to tcp connect , everything will be fine.
Anyone had this experience ? Any solution ?

I know what it is most likely - the 25588 is very common for this situation. Your max shared memory connections is a hard-limit set by NETTYPE, or defaults to 50 users (we may have increased that over the years, but it's a hard-limit regardless). So if INFORMIXSERVER is pointing to the onipcshm connection (shmem), you're running out of connections. When you change to the tcp connection, regardless of NETTYPE it's a dynamic set of connections (assuming sufficient semaphores, etc.). Keep in mind, you may not have NETTYPE set at all, and in that case, the defaults apply.
