Shared memory problem on HP 9K/755

Hey all - I have recently installed Informix Online 6.0, ESQL/C 6.0, and ESQL/Runtime 6.0 on an HP 9000/755 workstation with 256M RAM, and 4G disk space. Shared memory maximum (shmmax) is set at 64M in the kernel. After running through the configuration screens in onmonitor, I try to bring the database from off-line to quiescient mode, but receive the following message: fatal error: unable to initialize shared memory (or something very similiar) Upon return to the onmonitor menu, the bottom banner line says: shared memory not initialized for INFORMIXSERVER ms15xol1 Now, I have several questions... 1) Are there any know problems with shared memory on HP workstations? 2) The release tapes specify HP-UX 9.04. I am running HP-UX 9.05. Does this make a difference? 3) The errors in the online.log file are the result of me executing oninit -i and oninit -s manually. They read similiar to the following: listener-thread: err=-931: cannot locate ms15xsoc service/tcp in /etc/services (Believe me, it's already there, and yes, the service number is unique!) My sqlhosts file looks like this: ms15xol1 onipcshm manserv1 ms15xshm ms15xol2 onsoctcp manserv1 ms15xsoc I have a call into Informix tech. support (case# 306479) - they are looking into the problem; I just thought I'd try all you techies out on the net also. If Informix tech. support is reading this post, the gentleman I am working with is Randy (no last name). He has been very helpful and deserves a pat on the back... After dealing with Oracle tech support for the last couple of years (what tech support?), I am pleased to find someone interested in helping me solve this unusual problem. Thanks Randy (if you're out there), and pre-thanks to any and all who have any insights into this issue... Jay Wall
