SET SERVER
manager does not check how many links a server has with other TCP processes or
LINKMON processes.
If the value for this attribute is too large, it can cause the requests to the server
process to be queued at the server for an unacceptable length of time. For example,
if MAXLINKS is equal to 20, there could be 20 concurrent requests outstanding to a
server. If the transaction service time is 1 second, a response time of more than 20
seconds can occur.
If you omit this attribute, the default is an unlimited number of links. It is strongly
recommended that you set a value for MAXLINKS.
If this is an associative server, you should include links allocated by other
PATHMON environments when calculating the size of the RECEIVE-CONTROL
paragraph.
The value of MAXLINKS should always be greater than or equal to the value of
LINKDEPTH (unless MAXLINKS is set to 0).
MAXSERVERS number
for distributed server classes, specifies the maximum number of server process
reservations that can be distributed for this server class by all LCS processes in the
Pathway/XM environment. (During some internal Pathway/XM operations, it is
possible for up to twice the specified number of server process reservations to be
active simultaneously, for a very short time.) The value you specify is validated and
adjusted to conform to the value assigned to NUMSTATIC.
For replicated server classes, specifies the maximum number of server processes in
each PATHMON environment (in other words, per PATHMON process) that can run
at the same time.
For direct server classes, specifies the maximum number of server processes in this
server class that can run at the same time.
number must be a value from 0 through 4094. If you omit this attribute, the default
is 1.
NODE node-name
specifies a previously defined and added NODE object that defines the resources to
be used by this server class. The ROLE attribute for the NODE object must be set to
SERVER.
This attribute is required and must be specified before any other attributes for which
the node name is used to resolve file names.
Note. The value of SET SERVER MAXLINKS and the value of the TABLE OCCURS
clause in the RECEIVE–CONTROL paragraph of your COBOL server programs must
correspond. The value you specify for TABLE OCCURS must be greater than or equal to
the MAXLINKS value When the COBOL RECEIVE–CONTROL table is full, new requests
to the server fail with file-system error 12 (File in use). This error is most likely to occur
during peak transaction load times.
