Hi Jim and all,

Be a little careful with Data Guard in relation to "Database High Availability".

It brought a major database at a site of mine down in a screaming heap !!

Using Standby logs in maximum performance mode under heavy loads causes the Primary database online logs to be in a "confused" state (am I archived ? I think I am /am not) meaning Oracle refuses to overwrite the buggers and one stunned mullet of a database is the result.

The only "cure" is to bounce the database.

A particular "nasty" that we now have logged as a bug with metalink.

Cheers
