Hello,
I'm running Informix 7.30.UC7 with linux_lib-2.6.1 on 3.2-RELEASE.
oninit starts and runs fine:
-rwsr-sr-- 1 root informix 5210941 Jul 6 14:18
/usr/local/informix/bin/oninit*
i.e. it becomes euid 0 and egid 80 (informix).
It allocates shared memory segments like:
Shared Memory:
T ID KEY MODE OWNER GROUP
m 524288 1381451777 --rw-rw---- root informix
m 524289 1381451778 --rw-rw---- root informix
But when I try to run onstat as informix (which attempts to attach to
the first segment, with rw-rw---- mode) this is what I get:
syscall linux_ipc(0x17,0x52574801,0x0,0x1b0,0x0)
errno -13 'Permission denied'
I thought onstat might assume some weird euid/egid, but:
-rwxr-sr-x 1 informix informix 1421245 Jul 6 14:18
/usr/local/informix/bin/onstat*
Is this a bug in informix? I.e. shouldn't onstat attempt to perform an
shmget() first with 0x600 and then with 0x060?
Ultimately, I would want to run oninit as euid 80 (informix), but I'm
currently getting this:
Thu Jul 8 12:45:29 1999

Any thoughts, pointers, RTFM?
