MAXMSGPOOL
MAXMSGPOOL
This static parameter can be used to specify the maximum size of the extended
message pool.
If the size specified for the extended message pool is too large, configuration error
message 10002 is sent to the home terminal:
10002 maxTCBpool or Buffer/Msg pool too large
MAXOPENS
This static parameter specifies the maximum number of external openers (other than a
backup GDSX process) that the GDSX primary process will handle at one time. If
there are already MAXOPENS openers, an additional process attempting to open
GDSX will receive an open error (FETOOMANY).
MAXPCBPOOL
This static parameter can be used to override the calculation of the process control
block (PCB) pool space done automatically by TSCODE during process initialization.
In general, you should not need to set this parameter.
The size that TSCODE calculates for the pool can be overridden by using a TACL
PARAM command to assign a value to the external name MAXPCBPOOL, or by
assigning a value to the internal parameter name in the
USER^INIT^CONFIG^PARAMS user exit. TSCODE uses the user-specified setting
unless it is determined that the pool size would be insufficient, in which case TSCODE
uses the value that it calculated.
If the pool size specified by this parameter is too large (more than 131,064 bytes), or if
the size causes the running total calculated for control block pools, the extended buffer
pool, and the extended message pool to exceed 16,777,216 bytes, an error message
is sent to the home terminal, and the GDSX process stops with abend error 020. The
configuration error message is:
10010 maxPCBpool or previous pools too large.
