Environment

Release : 19.0

Component : CA IDMS/DB

Cause

The 599702 and 599703 messages indicate corruption in the CALC set. There are pointers to records that do not exist.

Resolution

CA IDMS/DB Audit will be able to fix these invalid pointers in the CALC chain. 

First, run a SIMULATE process to see the errors:

PROCESS,SUBSCHEMA=ssc_name,                           
 READYMODE=RETRIEVAL,SORTMSG=CRITICAL,STARTWITH=ALL,  
 AUDITTYPE=STANDARD                                   
AUDIT,CALCSETS, 
 CORE,SETLIMIT=300000,DBKEYTBL,STOPAFTER=999999  
AREA=area1,SWEEP                                  
AREA=area2,NOACCESS                                
FIX=SIMULATE,CALCSETS       
REPORTS=YES,RECDATA=HEX,SETMBRS=ERRSONLY
        

To perform the actual fix change the READYMODE and FIX parameters above  to UPDATE:

READYMODE=UPDATE,

FIX=UPDATE,CALCSETS
