In CICS® Transaction Server for z/OS®, Version 5 Release 2,
new system initialization parameters are available, and you might
find that some system initialization parameters that you used previously
are now obsolete. Also, the scope, default, or range of possible values
for some existing system initialization parameters has changed. You
might need to make changes to your system initialization table or
your CICS startup JCL because
of these changes.
To upgrade with the changes to CICS system
initialization parameters described in this section, follow these
instructions.
- Use the default system initialization table
- The unsuffixed default system initialization table (DFHSIT) is
supplied in the CICS SDFHAUTH
library. You can use the default table to start a CICS region using the default values. CICS loads DFHSIT by default if
your JCL does not contain a SIT parameter.
- Override defaults using the SYSIN data set
- To override default values, specify system initialization parameters
in a permanent member of a SYSIN data set. You can vary these during
testing by changing the data set member, avoiding the need to reassemble
suffixed system initialization tables. Nearly all system initialization
parameters entered at run time are used even on a warm start. The
main exceptions are the FCT and CSD parameters.
