Validate & clarify multiple archive log destination requirements for Oracle

XMLWordPrintable

      An Oracle database can configure multiple archive log destination paths for various purposes, some for recovery by storing files locally on the server, others for shipping logs to a physical standby, etc.

      It's critical that when such a set-up is enabled, the user explicitly configures the log.mining.archive.destination.name configuration. The connector expressly looks for rows that have STATUS=VALID and TYPE=LOCAL. So, if multiple rows match this criteria, this configuration is required.

      To solve this problem, we should first clarify this in the documentation, perhaps adding a subsection as a part of the set-up steps to confirm the database configuration and to know what settings are mandatory when configuring the connector.

      Secondly, we should probably add a validity check at the outset of the connector that examines the V$ARCHIVE_DEST_STATUS table and fetches the number of VALID destinations. We should emit a WARN message if we obtain more than one and the log.mining.archive.destination.name is not configured.
