The Override with Database File (OVRDBF) command can override a
local database file with a remote VSAM data set.
However, the following items must be considered:
- A POSITION value of *RRN works when the remote VSAM data set is an RRDS.
For all other types of VSAM data sets, *RRN causes a server message on the iSeries™ server.
- A POSITION value of *KEYB or *KEYBE causes a server message on the iSeries server when the remote file
is a VSAM path.
- Unless the CICS® system
programmer replaces the CICS/DDM-supplied exclusive file lock program, the
RCDFMTLCK parameter must have a lock condition value of *SHRRD or *SHRUPD.
All other lock condition values result in a server message on the iSeries server.
- CICS/DDM does not return the actual expiration date of the file to i5/OS™ DDM. Instead, it returns a
special value that indicates the expiration date is not known. This is true
even if the EXPCHK parameter has a value of *YES.
