i had created the standby db as procedure given.
it was working fine for fine
as 'm observing from few months, the logs are not getting applied. ( i mean it won't be the sync.)
every time, i was manually copying and register the log.
After manually applying the log on DR side, It will be in sync for days. ( i mean for 15 days).
later again, It won't be in sync.
can you please guide me..
plzz help

Please read & follow Posting Guidelines as stated in URL above

Every time a redo logfile is shipped from the primary, this action is recorded in the alert_SID.log file of the primary.

Every time a redo log file is applied at the standby, this action is recorded in the alert_SID.log file of the secondary.

When a problems occurs (shipping, receiving,applying) redo logfiles, these errors are also written to the alert_SID.log files.

Since only YOU can read these files, You're On Your Own (YOYO)!

In parameter file of Primary you need

standby_file_management = auto

WHY? As far as I know this parameter has NOTHING to do with redo log files themselves

Quote:

STANDBY_FILE_MANAGEMENT =

can be set to MANUAL or AUTO. If AUTO is specified, Oracle will automatically create files and
drop tablespaces on the standby database as the redo log stream is applied to the standby database.

As per Mr.Ana,

Check your alert_SID.log file in your primary database
