MAXRCVPOOL
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:
10005 maxRCBpool or previous pools too large.
TSCODE allocates the requester control block (RCB) pool from extended memory.
(See rcb^template in the DCCBDECS file in Appendix C.) The size in bytes of the RCB
pool is calculated as follows:
RCB pool size = $LEN(RCB^TEMPLATE) * (MAXOPENS + 1)
One is added to MAXOPENS so that if GDSX is run as a process pair, there will be an
RCB for the backup process open on the primary process.
MAXRCVPOOL
This static parameter may be used to override the calculation of RCV 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 MAXRCVPOOL, or by
assigning a value to the internal parameter name in the
USER^INIT^CONFIG^PARAMS user exit. TSCODE will use the user-specified
setting unless it is determined that the pool size would be insufficient, in which case
TSCODE will use 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:
10004 maxRCVpool or previous pools too large.
TSCODE calculates the size in bytes of the RCV pool as follows:
RCV pool size = RECEIVEDEPTH * 2
MAXTASKS
This static parameter specifies the total number of user tasks that may be active
simultaneously within the GDSX process.
