New user-replaceable programs

The following user-replaceable programs are added:

DFHJVMRO (formerly DFHSJJ8O)

DFHJVMRO defines Language Environment® run-time options for the Language Environment enclave in which the JVM runs. It replaces the user-replaceable program DFHSJJ8O, which was used in CICS® Transaction Server for z/OS®, Version 2 Release 1 and CICS Transaction Server for z/OS, Version 2 Release 2 to construct the Language Environment enclave for the JVM. DFHJVMRO performs the same functions as DFHSJJ8O.

DFHJVMRO defines storage allocation parameters for heap and stack and a number of other options. For CICS, the storage settings that are supplied in DFHJVMRO are more efficient than the default Language Environment storage settings, You can also modify these settings to match more closely with the storage usage of your JVMs.The source for DFHJVMRO is supplied in the CICSTS31.CICS.SDFHSAMP library.

For information on how you can tailor this user-replaceable program to your own requirements, see the CICS Customization Guide.

DFHAPXPO

DFHAPXPO is loaded during the PIPI preinitialization phase of each Language Environment enclave where C or C++ programs compiled with the XPLINK option are to be run. It allows you to alter the default Language Environment run-time options. See the z/OS Version 1.4 Language Environment Programming Guide, SC22-7561, for details of the Language Environment options that can be reset. The program must be written in Assembler language.

The source for DFHAPXPO is supplied in the CICSTS31.CICS.SDFHSAMP library.
