Issue/Introduction

Running IXMAINT it can happen to get the following error :

 PET202I USER ABEND(U0100) AT PSW(078D1000 80025C5A).        
 PET206I ABEND OCCURRED AT PGM(ADSDM485.ADSDM485+000D32) EPI(01/15/10 CCUWC50).

So it will be necessary to run a SQL report against the CA DISK Datacom Files DB in order to identify these duplicated ARCHVOL Keys.
How to build this report?
 

 

Environment

Release : 12.5

Component : CA Disk Backup and Restore

Resolution

In the CA DISK CCUWJCL target library there is sample member DBQDSI that is delivered during the installation.

It provides a sample SQL SELECT that is executed by the DBSQLPR utility and displays the fields in a readable format. 

You may start from this member and build the below report :

//SQLEXEC EXEC PGM=DBSQLPR                             
//STEPLIB   DD DISP=SHR,DSN=custom.disk.datacom.CUSLIB
