Modifying the Maximum Number of Simultaneous Sessions That a
Server Can Handle
You can tell the queue handler to modify the maximum number of simultaneous
sessions that a server can hold, using the MODIFY command. The syntax of the
command is:
►►──┬─MODIFY ─┬──id──┬─,MODIFY
─┬──┬─suffix──┬──,──SRV──=──(avlsess,avllrh,avlrrh)
──►◄
└─F ──────┘
└─,F ──────┘
└─jobname─┘ id The identifier that you used in the START command to start the queue handler.
suffix
The suffix of the server to be modified.
jobname
The job name of the server. This format must be used if the server has not
been started via the queue handler.
avlsess
For SNA file transfers, the maximum number of concurrently active sessions on
the specified server. It can be any numerical value from 0 up to the value
specified in the server MAXSESS initialization parameter. When 0 is specified,
the specified server no longer serves any file-transfer request.
For OSI file transfers, the maximum number of active transfer requests the OSI
server can handle. If the number of available server sessions (that is, FTAM
requests) is less than the maximum number of parallel FTAM sessions, the
request for a file-transfer session from a remote system is handled at the same
time as, and is not blocked by, a locally initiated file transfer.
avllrh
The maximum number of concurrently active local file-transfer requests the
specified server can handle. It can be any numerical value from 0 up to the
value specified by the AVLSESS parameter.
When 0 is specified, this server no longer serves any local file-transfer request.
When the value is equal to the AVLSESS value, the situation could arise where
the server serves only local file-transfer requests and no remote file-transfer
requests.
For an OSI server, this number must be equal to the AVLSESS value because
an OSI server can only handle local transfer requests.
avlrrh
The maximum number of concurrently active remote file-transfer requests that
the specified server can handle. It can be any numerical value from 0 up to the
value specified by the AVLSESS parameter.
When 0 is specified, this server no longer serves any remote file-transfer
request. When the value is equal to the AVLSESS value, the situation could
arise that the server serves only remote file-transfer requests and no local filetransfer
requests.
For an OSI server, this number must be set to zero because an OSI server can
only handle local transfer requests.
