Set Up CAIRIM to Load CA Datacom/MSM SVC at IPL

The CAIRIM service is the common driver in the CA Common Services for z/OS for a collection of dynamic initialization routines. The CA CSM setup utility loads the CA Datacom/MSM supervisor call (SVC) for the current initial program load (IPL). Set up CAIRIM to load the SVC automatically during each IPL.

Follow these steps:

1. Add one of the following statements to your CAIRIM startup procedure:
   • If you have only the CA Datacom/MSM SVC to load, use the following statement:

     //DBLIB DD DSN=run_time_caaxload,DISP=SHR
     

   • If you want to load a CA Datacom/MSM SVC that is different to an existing CA Datacom SVC, use the following statement:

     //DBLIBx DD DSN=run_time_caaxload,DISP=SHR
     

   run_time_caaxload

   Specifies the name of the CAAXLOAD CA Datacom/MSM library.

   x

   Specifies a suffix for the ddname to differentiate from other CAAXLOAD CA Datacom libraries.

   Limits: One to three alphanumeric characters

   The CAIRIM service is configured to load the CA Datacom/MSM SVC at IPL.

2. Add the following statement to the STEPLIB:

   DSN=run_time_caaxload,DISP=SHR
   

   run_time_caaxload

   Specifies the name of the CAAXLOAD CA Datacom/MSM library.

   Note: As with all data sets that are a part of this STEPLIB, the CA Datacom/MSM CAAXLOAD target library must be APF-authorized.

3. Add one of the following statements to the PARMLIB member that is referenced by your CAIRIM startup JCL procedure (usually the CAS9 procedure):
   • If you have only the CA Datacom/MSM SVC to load, use the following statement:

     PRODUCT(CA DATACOM) VERSION(BD12) INIT(DBRIMPR)   -
     PARM(Dsvc,DBSVCPR,TYP=3)
     

   • If you want to load a CA Datacom/MSM SVC that is different to an existing CA Datacom SVC, use the following statement:

     PRODUCT(CA DATACOM) VERSION(BD12) INIT(DBRIMPR)   -
     PARM(Dsvc,DBSVCPR,TYP=3,L=x)
     

   svc

   Specifies the SVC number that is set by the SVCNO keyword in the options file for the CA CSM setup utility.
