ALTER SERVER Command
The $ZPMON prefix can be omitted if you have previously specified $ZPMON
in an SCF ASSUME command.
You can specify the following options in any order. You must specify at least one
option:
AUTORESTART ntimes
specifies the persistence count of the server, where ntimes is an integer value in
the range 0 through 10. The persistence count is the number of times the OSS
Monitor will automatically restart the server during a 10-minute period.
The persistence count helps to prevent excessive attempts at restarting or an
endless loop during restart. The OSS Monitor counts the number of restart
attempts for each server during the previous 10 minutes; this number is the current
persistence count.
Once the current persistence count for a server reaches the number specified for it
by AUTORESTART, the OSS Monitor no longer attempts to restart the server and
generates an EMS event so that the operator can attempt to identify and correct a
possible problem. After the problem is corrected, the operator must take an action
that causes the current persistence count to be reset to 0; otherwise, the server
and any associated filesets will not be automatically restarted.
A server’s current persistence count is reset to 0 at the following times:
•
When the OSS Monitor starts or restarts
•
When an SCF STOP SERVER, START SERVER, or ALTER SERVER
command for the affected server is completed
•
When a START FILESET command for a fileset managed by the affected OSS
name server is completed
•
After the server has run for 10 minutes without being restarted
The current persistence count for each server is incremented when that server
terminates abnormally or is stopped by something other than SCF. The current
persistence count is not incremented because of processor failure.
When the AUTORESTART option is omitted from the ALTER SERVER command,
the previous value for the persistence count is unchanged.
BACKUPCPU backup_processor
specifies the processor number of the processor where the backup server process
runs, where backup_processor is either in the range 0 through 15 or equal to
-1.
The value -1 specifies that an OSS name server or the OSS sockets local server
does not run as a process pair, or that the OSS message-queue server selects as
its backup processor the next available processor in the node.
