Can DDTrans Views from a newer version of Oracle Gateway for DRDA (DG4DRDA) be used by an older version? (Doc ID 2424874.1)

Last updated on OCTOBER 16, 2019

Applies to:

Oracle Database Gateway for DRDA - Version and later
Information in this document applies to any platform.


You already have a version of Database Gateway for DRDA (DG4DRDA) installed on your system.  You install a newer version of DG4DRDA on the same server.
After this install, you  need to run the following Oracle supplied scripts on the DB2 target database to create DDTrans views:
(a) dg4db2_as400_drop.sql (drop prior versions)
(b) dg4db2_as400_tab.sql
(c) dg4db2_as400_vw<xx>.sql
(d) dg4db2_tx.sql (creates transaction_log table to enable 2 phase commit)

What impact will this have on the older version of DG4DRDA?  Can both versions of the gateway operate in parallel against the same DB2 database?
