This section summarizes the changes to CICS®
control tables across supported CICS TS releases. For each
CICS release, you must reassemble all tables by using the
latest macros, even if there are no changes to the macros. From CICS TS 5.3 onwards, CICS checks during initialization
whether the macro tables that it is loading have been reassembled, and if they have not been
reassembled, message DFHLD0110 is issued and CICS terminates.
If you are upgrading from an end-of-service release,
you can find information about the changes that are relevant to those releases in Summary of changes from end-of-service releases.

6.1 |
6.2 |
CHANGED:
Assembled PLTs are no longer processed by CICS. Instead
CICS reads the source of the tables from PARMLIB or DFHTABLE
and uses it to control PLT processing. This involves CICS
issuing an MVS™ service call IEFPRMLB
req=allocate from DFHAPTB, which might result in information message
IEF761I being issued. Ensure CICS has READ
access to data sets in PARMLIB or DFHTABLE concatenations. For details, see Program list table (PLT).

CHANGED with APAR PH09898:
The EXCI SURROGCHK parameter has been removed. Surrogate checking is always
done. Specifying SURROGCHK=YES in the EXCI options table, DFHXCOPT, is accepted for
compatibility. |
CHANGED:
- The EXCI SURROGCHK parameter has been removed. Surrogate checking is always
done. Specifying SURROGCHK=YES in the EXCI options table, DFHXCOPT, is accepted for
compatibility.
- The default for the CONFDATA parameter has changed to
HIDE. The HIDE option replaces HIDETC, which means that all
transport data is subject to CONFDATA. If the deprecated CONFDATA=HIDETC is
specified in DFHXCOPT, CONFDATA=HIDE is assumed, and no message will be issued.
