Changes to installation

No changes are needed as part of the CICS® installation process. However, if you have requirements which depend on support for the conversion of UTF-8 or UTF-16 data, you must enable the z/OS® conversion services and install a conversion image which specifies the conversions that you want CICS to perform.

Refer to the instructions in the z/OS Support for Unicode: Using Conversion Services manual SA22-7649 to find out the steps needed to set up and configure conversions supported though the operating system services.

If z/OS conversion services are not enabled, a message is issued by CICS to indicate this. That message can be suppressed if you do not need these services.
  • If the message is encountered when starting a CICS region that is expected to make use of these services, then an IPL is necessary to enable the z/OS conversion services.
To discover the status of z/OS conversion services after an IPL, use one of these commands from an MVS™ console:
/D UNI
To show whether z/OS conversion services were enabled.
/D UNI,ALL
To show whether z/OS conversion services were enabled, and which conversions are supported by the system.
For details of this, see the z/OS Support for Unicode: Using Conversion Services manual SA22-7649
