I’m not sure what you mean by “attend completely.”



Perhaps you can describe what cannot be accomplished with EBR that you are
trying to accomplish.

Mark,



I did some tests with this resource as described in the link below, but it does
not attend completely.

AND, for the purpose you describe Oracle has provided Edition Based
Redefinition.



I *think* that is the future.

If all you want to do is flashback to a specific restore point, there is no
need to set flashback logging on at the database level. A guaranteed restore
point is all you need. There should be no need to shutdown the database to
enable flashback logging.

Subject: Rollback via Fast Recovery Area - Oracle 11g



Hi,



I am planning a rollback (Fast Recovery Area) procedure in the Oracle 11g.

The idea is: Change the product version. For example, the product is in the
version 10.0 and I need to change some objects and data increasing the version
to 10.1.



If everything is OK I don´t need rollback, it is considered as GO

but for some reason, I can imagine many, the customer says: NOGO, so I need to
rollback to version 10.0



I did some research about Fast Recovery Area and commands are bellow.



My doubts are:



1.) Does anyone have experience with this recovery resource ?

2.) If I don´t need rollback , can I only drop restore point that all changes
made will stay in the database ?





/* ---------- BEGIN ------------------------- */



shutdown immediate

startup mount

archive log list

show parameter db_recovery_file



ALTER SYSTEM SET DB_RECOVERY_FILE_DEST_SIZE = 10g;

ALTER SYSTEM SET DB_RECOVERY_FILE_DEST = '<some folder in the database server
disk>';



select flashback_on from v$database;

alter database flashback on ;

select flashback_on from v$database;

create restore point teste guarantee flashback database;

select flashback_on from v$database;

select scn, garantee_flashback_database, time, name from v$restore_point;

alter database open;

flashback database to restore point stable;

alter database open resetlogs;



drop restore point stable;

select flashback_on from v$database;

alter database flashback on ;

select flashback_on from v$database;

flashback database to restore point teste;

alter database open resetlogs;

ALTER SYSTEM SET DB_RECOVERY_FILE_DEST_SIZE = 0;

ALTER SYSTEM SET DB_RECOVERY_FILE_DEST = '';



/* ---------- END ------------------------- */
