Chapter 4 Processing Data : Replace (Update) Processing

Replace (Update) Processing
A REPLACE request against an IDM table modifies the last TIBCO Object Service Broker IDMS/DB row retrieved.
Processing Considerations
You can modify all elements that were selected from MEMBER records, keeping the following points in mind:
You use CA‑IDMS to modify the CALC key of a record providing the modification does not violate the Duplicates not allowed option. However, modifying a CALC key causes CA‑IDMS to create a pointer from the new CALC location back to the physical location of the original record.
You cannot modify data elements of owner records that are retrieved with an OBTAIN OWNER directive. However, you can DISCONNECT and/or CONNECT CALC manual or optional owner records by modifying the CALC key of the owner record as follows:
If the Show if No owner field in the Verify Access Path screen is set to Y, you can do one of the following:
DISCONNECT the owner by setting its CALC key to null and issuing a REPLACE.
CONNECT the owner record by setting the null owner CALC key to a valid owner CALC key, and issuing a REPLACE.
Regardless of the setting of the Show if No owner field, the Gateway DISCONNECTs an owner and CONNECTs another owner when you change the existing owner record’s CALC key to another valid owner record’s CALC key, and issue a REPLACE.
