this is what was done to check recover until time.

1. rman > backup database /* 10.30 PM*/
2. insert into scott.dept values ( 90,'Q','Q'); /*10.33 PM*/
3. rman > shutdown immediate; /*10.33 PM */
4. rm users01.* /* 10.35 PM */
5. rman > startup; /* 10 .36 */
6.
/* run the script in another shell */
run {
allocate channel t1 type disk;
SET UNTIL TIME "to_date('03/10/2009 10:31:00','mm/dd/yyyy hh24:mi:ss')";
restore tablespace users;
recover tablespace users;
release channel t1;
}
7. rman > alter database open;

8. select * from scott.dept; /* entries from step 2 is here*/
My question is why I have data tha came into the table after
the recover time ?


Thanks

hi,

I guess you need to show the db time by sql when doing these tests. It will be more accurate.

You don't perform PITR for a tablespace like this. You did a full recovery that's why you didn't have to do OPEN RESETLOGS. Check RMAN Tablespace Point-in-Time Recovery (TSPITR).

The time is irrelevant in this situation.

As EBrian said,
this is not the way it should be done.
Check the log files. You will see that you are doing
a full recovery.

I agree. You check the log file and see what happened.

Thid script should not take effect if it doesn't run into error.
SET UNTIL TIME "to_date('03/10/2009 10:31:00','mm/dd/yyyy hh24:mi:ss')";
