Errors in file /<path>/<db_name>_arc2_29431.trc:
ORA-00322: log 6 of thread 1 is not current copy
ORA-00312: online log 6 thread 1: '/<path>/stby3b.rdo'
ORA-00322: log 6 of thread 1 is not current copy
ORA-00312: online log 6 thread 1: '<path>/stby3a.rdo'

CHANGES
none
CAUSE
This errors are written due to a very small timing window, when the SRL header
is being updated to reflect new contents from the primary and in the same way
the ARCH process is doing his activity and seeing a CF flog entry that reflects an earlier
state.
SOLUTION
check the alert<SID>.log for any further issues. As long as ORA-322, ORA-312 is not combined with other issues, you can ignore this error.
