ALTER SERVER Command
If the MSGMQB option is omitted, the maximum number of bytes allowed is
unchanged. The default value is the maximum, 65535.
This option is valid only for OSS message-queue servers.
MSGMSIZE msgmsize
specifies the maximum number of bytes allowed for a message. Valid values are in
the range 1 through 32000.
If the MSGMSIZE option is omitted, the maximum number of bytes allowed is
unchanged. The default value is the maximum, 32000.
This option is valid only for OSS message-queue servers.
SQLTIMEOUT seconds
specifies the number of seconds that the OSS name server waits for a response
from SQLCAT to a request. Valid values are in the range 60 through 300.
If the SQLTIMEOUT option is omitted, the timeout interval is unchanged.
This option is valid only for OSS name server processes.
Considerations
•
You can use the ALTER SERVER command on servers that are not currently
running.
•
Changes to the DESIREDSTATE attribute take effect immediately after using the
ALTER SUBSYS command, without stopping and restarting a server. Otherwise,
the ALTER SERVER command does not change the operation of a running server;
changes do not take effect until the server is stopped and restarted.
•
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.
