Preparing CICS for use with z/OS Language Environment

This section gives general instructions on enabling z/OS® Language Environment® to use a new CICS TS environment or to add z/OS Language Environment to an existing CICS TS environment. For more detailed information on CICS TS, refer to the CICS documentation, which is available at:

http://www-01.ibm.com/software/htp/cics/cics-library/

After CICS TS has been installed on your system, you must perform the following tasks:

Create a CICS TS environment if one does not already exist. This involves creating a CICS System Definition (CSD), journals, and a Global Catalog Set (GCD).
Copy CEECCICS from SCEERUN to an Authorized Program Facility (APF) data set. The data set should be concatenated in the STEPLIB when CICS is cold started.
Create the CESO and CESE Transient Data Queues. Sample Destination Control Table (DCT) definitions are supplied in SCEESAMP(CEECDCT).
Add required definitions to the CSD. Sample CSD definitions are provided in SCEESAMP(CEECCSD). These sample definitions create a group called CEE, which must be added to the installation LIST.
Add SCEERUN and SCEECICS to the DFHRPL concatenation.

The C runtime event handler module CEEEV003 is required for CICS TS support (in addition to the z/OS Language Environment interface modules). CEEEV003 must be link-edited as AMODE=31, RMODE=ANY, and loaded above the 16M line.

If you will be using the I/O stream library, complex mathematics, collection, or Application Support Class DLLs provided with the z/OS XL C++ compiler, you must define these DLLs in the CSD, and the CBC.SCLBDLL library must be added to the DFHRPL concatenation. Sample CICS CSD definitions can be found in CBC.SCLBJCL(CLB3YCSD).
