Oracle Database - Enterprise Edition - Version 10.2.0.4 and later
Summary
RAC database installation with 3 nodes. Each instance has two destinations configured for archiving. RMAN backup's will be run from only one of the three nodes - i.e all 3 nodes will not be used.
-
LOG_ARCHIVE_DEST_1 is set to the local file system of each node /PATH/
-
LOG_ARCHIVE_DEST_2 is set to an ASM disk group +FRA
How can you tell rman to backup the archivelogs from the FRA (flash recovery area), so that a connection to each node in the RAC cluster does not have to be connected to?
Solution
Just doing 'backup archivelog all;' or 'backup database plus archivelog;' is good enough. RMAN will use the archivelog that is accessible by that node (in this case +FRA logs) to complete the command. If none of the archivelogs are accessible by the node, then the command will error out.
