2. Use the OSS Monitor SCF ALTER SERVER command to change the ZOSSSERV entry for the
OSS message-queue server.
a. To reassign the process to a new primary or backup processor, change the corresponding
processor entry. If you do not explicitly assign a backup processor, the backup server
process is started in the next higher-numbered processor after the processor that runs the
primary server process.
b. To change behavior associated with use of the automatic startup service, change the
corresponding BACKUPCPUOK, MAXWAITTIME, DESIREDSTATE, or AUTORESTART
entry.
c. To change the message-queue configuration, change the corresponding MSGMQB,
MAXMQID, MAXMSG, or MSGMSIZE entry. The attribute values appropriate to the best
performance on a specific system depend on factors unique to each site’s configuration
and mix of applications.
Use nondefault values to tune message-queue performance on your system only after
gathering performance data, analyzing process memory requirements, and considering
the effects of a default configuration on system overhead because of the volume of
interprocess communication involved.
3. To restart the server, enter this OSS Monitor SCF command:
START SERVER $ZPMON.#ZMSGQ
If you use the STARTOSS utility at your site, you can also configure the OSS message-queue server
to be started by that utility. To do so, add the server name to the OSSINFIL file. See “OSSINFIL
File” (page 408) for more information.
Configuring OSS Sockets Local Server 2 Servers (AF_UNIX Release 2)
You cannot configure an OSS sockets local server 2 server. The OSS Monitor SCF ALTER SERVER
command is not valid for OSS sockets local server 2 servers.
Configuring the OSS Sockets Local Server (AF_UNIX Release 1)
You configure an OSS sockets local server by changing its entries in the Enscribe database
ZOSSSERV file. The following procedure assumes that no applications that use AF_UNIX sockets
have been started yet:
1. To stop the OSS sockets local server, enter this OSS Monitor SCF command:
STOP SERVER $ZPMON.#ZPLS
2. Use the ALTER SERVER command to change the ZOSSSERV entry for the OSS sockets local
server:
• To reassign the process to a new primary or backup processor, change the corresponding
processor entry.
• To change behavior associated with use of the automatic startup service, change the
corresponding BACKUPCPUOK, MAXWAITTIME, DESIREDSTATE, or AUTORESTART
entry.
3. To restart the server, enter this OSS Monitor SCF command:
START SERVER $ZPMON.#ZPLS
If you use the STARTOSS utility at your site, you can also configure the OSS sockets local server
to be started by that utility. To do so, add the server name to the OSSINFIL file. See “OSSINFIL
File” (page 408) for more information.
Configuring the OSS Transport Agent Servers
You cannot configure an OSS transport-agent server. The OSS Monitor SCF ALTER SERVER command
is not valid for OSS transport-agent servers.
