I just started playing around with Data Guard for the first time this week. For reasons I won't go into that MAY be related to age, I am using DGMGRL instead of OEM to manage the broker. The primary is called daffy and the physical standby is called daffysby. It seems OK in that I can see transactions get applied to daffysby but DGMGRL gives me a warning. It has to do with missing standby redo logs (SRLs) on the primary. I have SRLs in both the primary and the standby. The High Availability Best Practice guide alludes to putting SRLs in the flash recovery area (which I have not done at this point) but I am not convinced that is the issue. I've searched Metalink and the web for "missing SRLs" with not a whole lot of luck. All the redo logs are the same size.

My question is does anyone know to get rid of this warning? Can it be safely ignored? I would think not.

Any/all pointers/links/advice welcome. This is a test environment so I can try anything.


(hope this formats ok)
