Issue/Introduction

Description:

I have three LPARS that share the same ACF2 security database. When I first set up Cleanup for ACF2, I had a tracking file setup on each LPAR. I see that CA recommends using one shared tracking file. The use of two tracking files is supported but not common because of the additional overhead. So I want to merge the three tracking files into one and use that one for all three LPARS. How do I merge the tracking files?

Solution:

Create a 'composite' DB file by concatenating the current tracking 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. Here is a sample:

//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 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
