i5/OS only. Using the database file override to replace any occurrence of the specified filename, in any SQL statement, with the new library/file/member combination. The override occurs whether the file is qualified or not and includes any files that are qualified using DTLLIBRARYLIST.
Use the following format:
. The file to be overridden.
. The new library to use.
. The file in the new library to use.
. Optional. The member in the new library and file to use. *FIRST is used if nothing is specified. In the latter case the member *FIRST will be assumed.
If both the library list override (DTLLIBRARYLIST) and the database file override are specified, and a table exists in the DTLLIBRARYLIST as well as in the DTLOVRDBF, the DTLOVRDBF will take precedence.
