Update the CICS® system definition (CSD) file using the program definitions in the CEECCSD member in the Language Environment® sample (SCEESAMP). This member contains the necessary input to the CSD file utility program to define the Language Environment library routines to the CSD. The CSD group list that is used during CICS startup must include the CSD group that is associated with the Language Environment library routines. The group name for Language Environment routines is CEE in the sample CEECCSD.

For COBOL users, the OS/VS COBOL library routines (ILBOs) in Language Environment library SCEERUN are loaded by the operating system and do not require entries in the CSD.

The XPLINK program definitions in the CEECCSDX member, in the Language Environment sample (SCEESAMP) must be used to update the CICS system definition (CSD) file. Use the CEECCSDX member in addition to the CEECCSD member.

If you plan to run with program autoinstall and use the Language Environment CLER transaction, you must define the following statements using the CEDA transaction:

DEFINE PROGRAM(CEL4RTO) GROUP(CEE) LANGUAGE(ASSEMBLER)
EXECKEY(CICS)
DEFINE MAPSET(CELCLEM) GROUP(CEE)
DEFINE MAPSET(CELCLRH) GROUP(CEE)
DEFINE TRANS(CLER) PROG(CEL4RTO) GROUP(CEE)

Tip: If you use program autoinstall, Language Environment event handler modules in the range CEEEV001-CEEEV017 that are present in the CEE.SCEERUN might load during CICS/LE initialization, depending on the definitions in the CICS CEECCSD member and the autoinstall program. You can remove program definitions from the CEECCSD member to prevent them from being loaded during CICS/LE initialization. However, if autoinstall is active, the missing definitions from the CEECCSD are loaded dynamically unless the autoinstall program is modified to bypass any Language Environment modules that you do not want loaded.

To prevent this from occurring, you should start CICS with PGAIPGM=INACTIVE in the CICS SIT. To take advantage of the program autoinstall feature, you can create a PLTPI program to perform a CICS SET SYSTEM PROGAUTOINST (auto_active/cvda) to enable the feature for use later on in initialization. The URM can also be set in the same PLTPI program through the same SET SYSTEM command with the PROGAUTOEXIT parameter. If you do want to run with the autoinstall program, you can modify the autoinstall exit program to bypass any CEEEV0* modules that you do not want loaded.

Table 1. Excluding programming language support under CICS

If you do not run	Exclude these program definitions from the CEECCSD sample job
COBOL applications under CICS	CEEEV004 , CEEEV005, IIGZMSGT, all programs that start with IGZ
C/C++ applications under CICS	CEEEV003, IEDCMSGT, all programs that start with EDC or CEU
PL/I applications under CICS (Also VA PL/I)	CEEEV010, CEEEV011, IIBMMSGT, all programs that start with IBM®

Guideline: If you use autoinstall and want to exclude one or more languages using this technique, be sure to implement these changes in your autoinstall exit to prevent them from being added dynamically.
