The child enclave gets its runtime options from one of the sources
discussed in Specifying runtime options under CICS. The runtime
options are completely independent of the creating enclave, and can
be set on an enclave-by-enclave basis.
Some of the methods for setting runtime options might slow down
your transaction. Follow these suggestions to improve performance:
- If you need to specify options in CEEUOPT specify only those options
that are different from system defaults.
- Before putting transactions into production, request a storage
report (using the RPTSTG runtime option) to minimize the number of
GETMAINs and FREEMAINs required by the transactions.
- Ensure that VS COBOL II transactions
are not link-edited with IGZETUN and IGZEOPT, which are no longer
supported and which cause an informational message to be logged. Logging
this message for every transaction inhibits system performance. The
sample user condition handler CEEWUCHA can be used to prevent this
informational message from being logged. See the Enterprise COBOL for z/OS library. for more information.
