Probably because the rman records are saved to the control file, even if you are using a recovery catalog. I suppose this results in some recursive SQL which finds it's way into the redo stream which is then replicated to the stand-by database where it is replicated and finds it's way to the control file. I don't have a configuration to test this theory, but I suspect that may be the cause.

  Subject: RMAN and Data Guard

  I set up a 10.2.0.3 primary and physical standby database pair and configured each to use RMAN "incremental backups" with the Flash Recovery Area (FRA). I then registered each database to separate RMAN recovery catalogs, performed a full "incremental save" of the primary to the FRA followed by a BACKUP RECOVERY AREA taking the FRA contents to tape. I was then able to connect to the RC of the standby from the standby and view the save of the primary via RMAN "list" commands. How is this possible with separate RCs and controlfiles? This configuration mirrors Oracle's "Geographically Too Distant" scenario from the DG Admin Guide (chapter 10), which I may face. Note that I did use the backup with a TAG identifying the database TNS alias the save originated from. Can anyone shed some light on this.

  Thanks!!
