Stopping servers
28 Adaptive Server Enterprise
If Adaptive Server is configured with a memory size that is greater than the
MAXSHMSEGSIZE parameter in the operating system then Adaptive Server
may create additional shared memory segments and for every additional shared
memory segment that it creates, an additional file with
SERVER_NAME.srg[N] (where N ranges from 0 – N), is created under
$SYBASE/$SYBASE_ASE.
When Adaptive Server is shut down in a normal manner, the shared memory
files are automatically removed. If Adaptive Server crashes or is stopped with
the
kill -9 command, these files are not deleted. You need read and write
permissions on these files to restart Adaptive Server after a crash or a
kill -9
command, because Adaptive Server must be able to overwrite the previously
created shared memory files.
If Adaptive Server or Backup Server is killed abnormally it also leaves shared
memory segments. Use the
ipcs and ipcrm commands to identify and remove
these shared memory segments that have “NATTACH” count as “0”.
See the UNIX man pages for more information about
ipcs and ipcrm.
