Issue/Introduction

Performing a CA IDMS upgrade to 19.0.

In CONFIG  JOB10 the BACKUP step fails with:

UT000039 Starting BACKUP of file SYSTEM.DCSCR                
UT015000 Unexpected page read.  Expected=50,001. Found=88,001.

 

Environment

Release : 19.0

Component : CA IDMS/DB

Resolution

Check that the JCL is pointing to the correct file.

In the backup statement check the file name:

BACKUP ..
SYSTEM.DCSCR

The DCSCR DD statement should point to the DDLDCSCR file.

//DCSCR DD DISP=SHR,DSN=idms.SYSTEM.DDLDCSCR

If the JCL is correct then the page range on the physical file is incorrect.

The scratch area is logically empty at the start of each CV so there is no need to back up the file.

Most sites these days use the scratch area in memory so the physical file is never used. It is possible the page range was changed at some point without formatting the file.

To resolve the problem run IDMSBCF to FORMAT the SYSTEM.DDLDCSCR area. Use this input:

CONNECT TO SYSTEM;       
FORMAT FILE SYSTEM.DCSCR;
