Reply with quote

We are trying to expand one of the child segment (add 4 bytes).
i did following steps

1. Unloaded the before expansion database. Unload file is VB file.
2. Using COBOL program, i have expanded VB file for perticular child segment (add 4bytes at end). We can see child record with expanded data in output file (VB file).
3. We are able to successfully Reloaded the Expanded VB file to IMS Database using utility DFSRRC00.

Problem is: when i browse the IMS database thru File-aid the child segment (4 bytes are added at end), last 4 byte are having low-values.

Could any one please help me, is there any special things need to consider in COBOL program while expanding Unloaded file?

i cannot answer your question.

But I wonder: did you expand the key field or any other field? If the latter is the case, I think you could have easily done it using regular unload/reload. AFAIK you don't even need to reorganize as long as you don't append to the key field. I think we do this.

We are not adding any key fields. Just we are adding normal four indicators, each of 1byte at end of the Segment.
