Change the Language Environment default run-time options to be
consistent with the requirements of your computing environment. See
the "Recommended Setting" section in the
z/OS Language Environment Run-Time Migration Guide, GA22-7565
or
OS/390 Language Environment Migration Guide, SC28-1944, for
assistance in changing the run-time options to match your
environment's needs.
Assess storage needs. Storage requirements may be larger for
Language Environment than for your current environment. See
"Determining DASD Storage Requirements" in
z/OS Language Environment Customization, SA22-7564 or
Language Environment for OS/390 Customization, SC28-1941,
for help
in assessing your storage needs. Virtual storage requirements for
placing library routines above or below the 16M line may also
increase. See "Recommended Settings for C, C++, COBOL, Fortran, and
PL/1" in
z/OS Language Environment Run-Time Migration Guide, GA22-7565, or
OS/390 Language Environment Migration Guide, SC28-1944,
for recommended settings. IBM recommends that you begin a
transition to LanguageEnvironment by using a STEPLIB approach. Using STEPLIB allows youto phase
in one region (for CICS(TM) or IMS(TM)), batch (group ofapplications), or user (TSO) at a time.
Gradually as the majorityof your applications use Language Environment you can placeLanguage
Environment into LNKLST.
