Re: Standby database: Skipping logs?

No. As per the docs, the MANDATORY clause in the LOG_ARCHIVE_DEST_n parameter suffices. Making a DEST mandatory should make Oracle treat the dest as dearer than life. i.e. it would do everything in its power (including stopping the database) to write that destination before it over-wrote online logs. Just like it does for the regular log_archive_dest.

Thats why I was shocked to see Oracle merrily recycle online logs before it successfully wrote the remote archive log.

Is it just me? Has anyone else used the standby database feature in a production environment with a large volume of redologs (10M of redo per second during peak period lasting about 1 hour).
