ALTER SERVER Command
•
The primary and backup server processes cannot be configured in the same
processor.
•
The ALTER SERVER command can be used only by super-group users (255,nnn).
•
For the OSS message-queue server, a BACKUPCPU value of -1 means the server
is to use for its backup process the processor specified by the TACL PARAM
BACKUPCPU (see Currently Used TACL PARAMs for the OSS Monitor on
page 2-11). If the TACL PARAM BACKUPCPU is not defined or is invalid, the OSS
message-queue server automatically picks an available processor with the next
higher or lower processor number than the primary processor. When the TACL
PARAM BACKUPCPU specifies a valid processor number, the OSS Monitor tries
to add that processor to the OSS message-queue server configuration before
bringing up the OSS message-queue server.
•
The INODECACHE, LINKCACHE, MSGMQB, MAXMQID, MAXMSG, MSGMSIZE,
and SQLTIMEOUT parameters are not valid when the OSS sockets local server is
specified in an ALTER SERVER command.
•
The INODECACHE, LINKCACHE, and SQLTIMEOUT parameters are not valid
when the OSS message-queue server is specified in an ALTER SERVER
command.
•
OSS transport agent servers cannot be modified and are not a valid server type for
the ALTER SERVER command.
Examples
•
To change the configuration of the OSS name server process $ZPNS to use
processor 0 as its primary processor and processor 1 as its backup processor,
enter the following command:
ALTER /OUT CMDLOG/ SERVER #ZPNS, CPU 0, BACKUPCPU 1, &
INODECACHE 2048, LINKCACHE 4096
This command assigns the OSS name server process the default value of 4096
entries for its link cache and a value of 2048 entries for its inode cache. This
command also sends informational messages to the file CMDLOG.
•
To change the configuration of the OSS message-queue server process $ZMSGQ
to use processor 3 as its primary processor and processor 1 as its backup
processor, enter the following command:
ALTER /OUT CMDLOG/ SERVER #ZMSGQ, CPU 3, BACKUPCPU 1, &
MAXMSG 8192
This command assigns the OSS message-queue server process the value 8192 as
the maximum number of messages allowed on the message queue. This
command also sends informational messages to the file CMDLOG.
•
To change the OSS sockets local server process $ZPLS so that three attempts to
restart it in its primary or backup processor are made when its primary processor is
