CHANGES

 Database was upgraded to 11.2.0.4

CAUSE

Per 'unpublished' Bug 8740124, as of 11.2.0.4, we now include the current standby redo log as part of an RMAN archivelog backup at the standby site. This is achieved by forcing a log switch at the primary site.

However, the connection to the primary failed when attempting to do so.

This is due to this bug:
      Bug 17580082 - ACTIVE STANDBY - RMAN-06820: WARNING: FAILED TO ARCHIVE CURRENT LOG AT PRIMARY
 

SOLUTION

Workaround

Do not use operating system authentication to login with RMAN. Use a username and password.

That is, do not use just the "/" (operating system authentication) connect to the standby database:

$ rman target /

Instead put in the username and password for the SYSDBA user:

$ rman sys/password
