Application is failing with bugchecks when accessing CODASYL DBMS database snapshot files. Database access may not be possible at all via the application.
Bugchecks show either:
%DBM-F-CANTREADDBS, error reading pages 18:631-631
-DBM-F-BADPAGRED, read requesting physical page 18:631 returned page 16389:5254
%DBM-F-CANTREADDBS, error reading pages 17:45571-45575
-SYSTEM-W-ENDOFFILE, end of file
The above lines are in the DBOBUGCHK.DMP file. Use the bugcheck summarizer (<Note: 165466.1>) or edit the file.
The numbers before the first colon are storage area numbers and these equate to snapshot storage areas. This can be determined by:
$ sea hdr.lis "area id number is 17" /win=(1,0)
This will show if the area is indeed a snapshot area.
