Merge Cleanup tracking files with a shared security file

Products

Issue/Introduction

There are three LPARS that share the same Top Secret security file. When Cleanup was first set up, there was a Cleanup tracking file on each LPAR. It is recommended to use one shared tracking file. The use of two tracking files is supported but not common because of the additional overhead. How do I merge the three tracking files into one to be used on all three LPARs?

Environment

Release: 
Component: Cleanup for Top Secret

Resolution

Create a 'composite' DB file by concatenating the current files in IEBGENER SYSUT1. The resulting composite SYSUT2 file should then be updated via the ***#DBU program. The result should be a new 'merged' DB file that can be used moving forward. Fix RO68924 is required to handle duplicated records.

Here is a sample job:

//jobcard 
//STEP1    EXEC PGM=IEBGENER 
//SYSPRINT DD SYSOUT=* 
//SYSUT1   DD DSN=CLEANUP.LPAR1.TRACKING.FILE,DISP=SHR 
//         DD DSN=CLEANUP.LPAR2.TRACKING.FILE,DISP=SHR 
//         DD DSN=CLEANUP.LPAR3.TRACKING.FILE,DISP=SHR 
//SYSUT2   DD DSN=CLEANUP.ALLLPAR.TRACKING.FILE, 
//          UNIT=SYSDA,DISP=(NEW,CATLG,DELETE), 
//          DCB=(RECFM=VB,LRECL=584,BLKSIZE=27998), 
//          STORCLAS=xxxxxxxx, 
//          SPACE=(CYL,(nn,nn)) 
//SYSIN    DD DUMMY
