OCI-16777
Cause
Either a destination (LOG_ARCHIVE_DEST_N initialization parameter) was manually deleted or no LOG_ARCHIVE_DEST_N initialization parameter was available to set up redo transport for the member.
Action
Check the Oracle Data Guard broker log file and the Oracle alert log file for more details. If there are sufficient LOG_ARCHIVE_DEST_N initialization parameters available, re-enable the configuration using the DGMGRL CLI ENABLE CONFIGURATION command to ensure all members are receiving redo data. If there are an insufficient number of LOG_ARCHIVE_DEST_N initialization parameters available, consider using the RedoRoutes property to take advantage of available LOG_ARCHIVE_DEST_N initialization parameters on other members so that all members are receiving redo data.
