Unrecognized shared memory "entry"
2007-12-24 22:08:00
We're running an Oracle 8.1.7.2 database on a Sun 420R, Solaris
2.6.
Recently we had a look at the shared memory allocation via the
'ipcs -a'
command and noticed that there is a "no-entry" listing in the
semaphore
section:
$ ipcs -a
IPC status from <running system> as of Sun Mar 10 15:07:42 2002
Message Queue facility not in system.

This doesn't appear on any of our other Solaris 2.6, 2.7 or 2.8
servers.
Does anyone know what the "no-entry" semaphore listing means?
The specific OS version is:
$ uname -a
SunOS scmsdb01 5.6 Generic_105181-29 sun4u sparc SUNW,Ultra-60
