4.11 foreignlogRecordSpecifier

Purpose

Use the foreignlogRecordSpecifier subclause to specify a set of foreign archived redo log files for use in RMAN operations.

Usage Notes

Foreign archived redo log files are received by a logical standby database for a LogMiner session. Unlike normal archived logs, foreign archived logs have a different DBID. For this reason, they cannot be backed up or restored on a logical standby database.

A logical standby database creates foreign archived logs in the fast recovery area if the following conditions are met:

  • A fast recovery area is configured on the logical standby database.

  • a LOG_ARCHIVE_DEST_n initialization parameters is set to 'LOCATION=USE_DB_RECOVERY_FILE_DEST' with a proper VALID_FOR setting to receive foreign archived logs.

  • The COMPATIBLE initialization parameter is set to a value greater than or equal to 11.0.0.
