Question: When I
run this query in Standby server (oracle 11g and maximum
availability)
SQL> select
max(sequence#),
applied
from
v$archived_log
group by
applied;
MAX(SEQUENCE#) APPLIED
-------------- ---------
20 YES
21 IN-MEMORY
This query always show applied column 'in-memory' for last
archivelog that transfer to standby server . What should I
do to change status of applied column from 'in-memory' to
'YES' for last archivelog transfer to standby. This
issue always exist for last archive log that transferred to
standby server.
Answer: Sorry I don't know the
details for your issue! The Oracle docs note this on
the applied column of v$archived log:
The archived column whether an archived redo log
file has been applied to the corresponding physical standby
database. The value is always NO for local destinations.
This column is meaningful on a physical standby database
for rows where REGISTRAR = RFS:
If REGISTRAR = RFS and APPLIED = NO,
then the log file has been received but has not yet been
applied.
If REGISTRAR = RFS and APPLIED = IN-MEMORY, then
the log file has been applied in memory, but the datafiles
have not yet been updated.
If REGISTRAR = RFS and APPLIED
= YES, then the log file has been applied and the datafiles
have been updated.
This column can be used to identify log files that can be
backed up and deleted. When used for this purpose, the value
IN-MEMORY should be treated as if it were NO.
