Here
are some actions you can take to maximize performance with
Language Environment on
CICS:
- Set the CICS SIT option RUWAPOOL to YES. Doing so can reduce the CICS
GETMAIN and FREEMAIN activity when CICS LINK is used.
- Tune your Language Environment storage
runtime options. Doing so can keep the CICS GETMAIN and FREEMAIN activity
to a minimum, and avoids the overhead that occurs when an increment is needed.
If you are using CICS Transaction Server, Version 1 Release 3 or later, the
automatic storage tuning is performed when you set the CICS SIT option AUTODST
to YES.
- You
might not want to use TERMTHDACT(DUMP) and TERMTHDACT(UADUMP) in production,
because these TERMTHDACT suboptions can cause a lot of time to be spent writing Language Environment dump data to transient
data queue CESE when a transaction abends.
- Do not run with runtime options RPTOPTS(ON) or RPTSTG(ON) in production.
These options have a significant impact on performance.
- If you are getting any warning messages written by Language Environment to
CESE, make changes so that they are not issued.
