Customize the PowerExchange Listener JCL for IMS Catalog Use

You must edit the PowerExchange Listener JCL or PROC to add the DD statements that define the data sets used to get DBD information for IMS source objects from the IMS catalog. PowerExchange transparently uses the IMS catalog API, DFS3CATQ, to get DBD information in DBDGEN format and uses the IMS Catalog Library Builder Utility, DFS3LU00, to get DBD information in source format.

Add the following DD statements to the Listener JCL or PROC:

DD Name	Description
DD DBDSOR	Specifies the PDSE to which the IMS Catalog Library Builder Utility, DFS3LU00, writes DBD information in source format for IMS source objects. You must pre-allocate this PDSE. Make sure that the PDSE name specified in this DD statement matches the PDSE name in the LU00FILE statement in the DBMOVER configuration file. When you create data maps, the source object metadata stored in this PDSE is sent to the local machine where you run the PowerExchange Navigator or infacmd pwx createdatamaps utility. After the data maps are successfully created, PowerExchange automatically deletes DBD information from the PDSE. No PDSE maintenance is required.
DD DSN =IMS`xxx`.SDFSRESL	Defines the IMS`xxx`.SDFSRESL library that contains the IMS catalog API DFS3CATQ program and macro.
LUSYPRT DD SYSOUT=*	Defines the data set that contains statistics from IMS Catalog Library Builder utility, DFS3LU00, activity.
SYSPRINT DD SYSOUT=*	Defines the data set that contains control cards that the PowerExchange Navigator passed to the IMS Catalog Library Builder utility, DFS3LU00.

Sample JCL:

//STEPLIB  DD  DSN=CEE.SCEERUN,DISP=SHR        
//         DD  DSN=&HLQ..LOADLIB,DISP=SHR      
//         DD DSN=DSNB10.DSNB.SDSNEXIT,DISP=SHR
//         DD DSN=DSNB10.SDSNLOAD,DISP=SHR     
//*        DD DSN=DSN910.SDSNEXIT,DISP=SHR     
//*        DD DSN=DSN910.SDSNLOAD,DISP=SHR     
//*        DD DSN=ICU.PMICU.LOAD,DISP=SHR      
//* IF USING IMS THEN CUSTOMIZE BELOW 
//        DD DSN=IMS1510.SDFSRESL,             
//            DISP=SHR                         
//LUSYSPRT DD  SYSOUT=*                           
//SYSABEND DD  SYSOUT=*                           
//SYSOUT   DD  SYSOUT=*                           
//SYSPRINT DD  SYSOUT=*                           
//CEEDUMP  DD  SYSOUT=*                           
//DBDSOR   DD  DISP=OLD,DSN=GRAHAM.IMS.DFS3LU,    
//             DCB=(RECFM=F,LRECL=80,BLKSIZE=80)
