Enabling z/OS conversion services
To obtain the benefits of z/OS conversion
services for data conversion, perhaps because your system requires
support for the conversion of UTF-8 or UTF-16 data to EBCDIC, you
must enable the z/OS conversion
services and install a conversion image that specifies the conversions
that you want CICS to perform.
Upgrading the CSD for CICS-supplied and other IBM-supplied resource definitions
Upgrade the CICS-supplied resource definitions using the
UPGRADE function of the CSD utility program DFHCSDUP. If you have
resource definitions in your CSD that support other IBM® products, such as z/OS, you might need to upgrade these also.
Upgrading user-modified CICS-supplied resource definitions
When you run the UPGRADE function of the CSD utility program
DFHCSDUP, ensure that you manually upgrade any CICS-supplied definitions
that you have modified in earlier releases.
Upgrading copies of CICS-supplied resource definitions
If you have made copies of CICS-supplied resource definitions,
you might need to change your copies to match the changes that have
been made to the supplied definitions for this release. To help you,
member DFH$CSDU in library SDFHSAMP contains ALTER commands that you
can apply using the CSD utility program DFHCSDUP.
DSA size limits
It is not advisable to set the size of individual dynamic
storage areas (DSAs), and usually it is not necessary. However, it
is possible to set the size of some DSAs by using the CDSASZE, UDSASZE, RDSASZE, ECDSASZE, EUDSASZE, ESDSASZE,
and ERDSASZE system initialization parameters.
