Answer 1

Hi
ANSWER TO QUESTION 1
Database parameter "STANDBY_FILE_MANAGEMENT" enables or disables automatic standby file management. When automatic standby file management is enabled, operating system file additions and deletions on the primary database are replicated on the standby database. STANDBY_FILE_MANAGEMENT is only applicable to Physical standby databases.
Values:
MANUAL
disables automatic standby file management
AUTO
enables automatic standby file management
Setting STANDBY_FILE_MANAGEMENT to AUTO causes Oracle to automatically create files on the standby database and, in some cases, overwrite existing files. Care must be taken when setting STANDBY_FILE_MANAGEMENT and DB_FILE_NAME_CONVERT so that existing standby files will not be accidentally overwritten.
ANSWER TO QUESTION 2
There are a few ways to verify that your standby database is in sync with the primary;
a) This command (run it on the standby db) will show you which redo logs have/have not been applied. It is is a quick way to confirm that the redo logs are being applied to the standby.
SELECT SEQUENCE#,APPLIED
FROM V$ARCHIVED_LOG
ORDER BY SEQUENCE#;
b) Another way is to check the alert.log on both the primary and the standby. If there are any problems during the migration of redo logs from the primary to the standby then you will see this in the alert logs.
