Issue/Introduction

Executing LIBGET in batch seems to loop when a member to be copied already exists on target PO data set.

 

 

Environment

Release: 4.3

CA-Librarian-Access Method

Resolution

LIBGET is waiting for user response for whether the member is to be replaced or the request to be cancelled. This cannot be resolved in batch execution. As it is consuming CPU time it appears like being in a loop.

One possible solution is shown in the JCL sample below doing the copy to a temporary PDS and use IEBCOPY to add or replace the member on the target PDS.

//BATCHTSO EXEC PGM=IKJEFT01,DYNAMNBR=256
//STEPLIB  DD  DSN=your.LIBR43.SPxx.CAILIB,DISP=SHR
//*
//SYSPROC  DD  DSN=SYS1.CLIST,DISP=SHR
//         DD  DSN=SYS2.CLIST,DISP=SHR
//         DD  DSN=SYS1.PROCLIB,DISP=SHR
//         DD  DSN=SYS2.PROCLIB,DISP=SHR
//         DD  DSN=ISR.V3R1M0.ISRCLIB,DISP=SHR
//         DD  DSN=GIM.SGIMCLS0,DISP=SHR

LIBGET memname,DSSOURCE('your.original.master'), +
READONLY,INCLUDE(RESEQ), +
TSODSN(TEMP(newmembr)
/*

Other Relevent Information:

There might be other approaches as well to achieve this, like checking first whether the member already exists on the PO data set and then delete it prior to execute LIBGET, but the given sample is one of the easiest.
