    Data Guard setup between 11gr1 and 11gr2

      Can we setup Data Guard between 11gr1 (Primary) and 11gr2 (Secondary).

          No. They should be the same version. Refer to B28294-03 for more details. (see 2.3.2 Oracle Software Requirements)

          During a rolling upgrade, you can run different releases of the Oracle database but that should be the only time.

          The first time I ran a quarterly CPU patch on a Data Guard I had to stop for a moment because part of we wanted to run the SQL on the Standby too. Of course Data Guard handles this.
