Hi,

I am planning to use Data Guard facility in Oracle 10g database. Could someone please answer few of my queries:

1) I would like to have a standby database, which can be used if the primary goes down and also for reporting and other queries (read-Only).

2) Please explain me in simple words the difference between Physical and Logical standby database. I have to explain non-technical users (management) regarding this.

3) What is Sync and Async redo log apply?

4) When i manipulate data (Insert,Delete,Update) in logical standby database, will these changes reflect in Primary database synchronously?

5) Which type of REDO APPLY is better: Managed Recovery Process(MRP) or Real Time Apply(RTA)?

6) can the redo data be deleted if its obsolete or is it deleted automatically by oracle?

7) If i want to take backup, should i take it from primary or standby database? If standby, then the database should be in which mode (Read-only or Recovery Mode)

Best Regards,

FIRST read the documentation, THEN come back if you have any question.
There is no reason to answer here to RTFM questions.

Regards
