I am trying to write a SQL query against my catalog database which has over 770+ databases registered to report SID, start_time,end_time,status of the last successfull completed backup and unable to get what i need.

1) First I tried to get it from rc_rman_status and did not get the 770+ list of databases. Then compared and ran another query against rc_databases and got back 770+. So what is the purpose of rc_rman_status view ANYONE??

2) Wrote another query and joined rc_database and rc_backup_set but get too many rows for one DBID and unable to group start_time and end_time. I thought rc_backup_set has single set info but returns rows as if it a piece. Try yourself

3) Oracle recommends to use centralized catalog repository but I have yet to see any good reporting tools or queries from RMAN catalog database. I don't want to use RMAN list, report commands because we have 770+ database

Apprciate if anyone can test his/her query against their current catalog and let me know if it works as below

SID START_TIME END_TIME STATUS
============================================
ABC 25-MAY-2006 26-MAY-2006 AVAILABLE
XYZ 23-MAY-2006 24-MAY-2006 NO BACKUP

Thanks in advance

1) According to the Recovery Manager Reference guide:

"This view contains information about the history of RMAN operations on all databases associated with this recovery catalog. It contains essentially the same information as V$RMAN_STATUS, except that it does not contain information about current sessions.

All RMAN operations such as backups, restores, deletion of backups, and so on are logged in this table. The table is organized to show the status of each RMAN session (the invocation of an RMAN client, including all actions taken until the RMAN client exits), operations executed during the session, and recursive operations."

2) The data looks right to me:

SQL> SELECT db_name, row_type, start_time, end_time, operation, status, mbytes_processed
  2  FROM   rc_rman_status
  3  WHERE  db_name = 'ORCL'
  4    AND  start_time > SYSDATE - 1
  5  ORDER  BY END_TIME
  6  /

DB_NAME  ROW_TYP START_TIM END_TIME  OPERAT STATUS    MBYTES_PROCESSED
-------- ------- --------- --------- ------ --------- ----------------
...
ORCL     COMMAND 12-JUN-06 12-JUN-06 BACKUP COMPLETED       1.97998047
ORCL     SESSION 12-JUN-06 12-JUN-06 RMAN   COMPLETED               16
ORCL     COMMAND 12-JUN-06 12-JUN-06 BACKUP COMPLETED       16.5478516
ORCL     SESSION 12-JUN-06 12-JUN-06 RMAN   COMPLETED                0
ORCL     COMMAND 12-JUN-06 12-JUN-06 BACKUP COMPLETED       .468261719
ORCL     SESSION 12-JUN-06           RMAN   RUNNING                  0
ORCL     COMMAND 12-JUN-06           BACKUP RUNNING                  0


3) I fully agree - a better tool would be great!

I don't see the same problem on my catalog. My guess is that you've registered 711 databases in your catalog, but only 17 databases use the catalog for backups.

I have verified that 90% of the databases are backedup. Do you have any other verification check. I check backup_piece and backup_set and I do get information

This view only gets populated starting with oracle version 10.2 as target db.
for e.g if you connect from Oracle 10.2.0.3 and your Catalog db is Oracle 10.2.0.4 then your will not get the above entry.

You mention:

Yet you contradict yourself by saying "if you connect from Oracle 10.2.0.3 and your Catalog db is Oracle 10.2.0.4 then your will not get the above entry." I would say a 10.2.0.3 database is a 10.2 database ?

I realize my post is months late, sorry, but I came across this thread and it's helping me clean out old databases from our recovery catalog, thanks! Smile

One of the basic queries I use is this:

select * from rc_database where db_key not in (select db_key from rc_rman_status)

RC_RMAN_STATUS: This view contains information about the history of RMAN operations on all databases associated with this recovery catalog.

Now I know which DBs have never been backed up by the catalog. From there I can refine it to weed out the DBs that haven't been backed up in the last 90 days (outside of our recovery window and probably not on the network anymore).

If your DBs aren't showing up in your catalog are you positive you're backing up your DBs to your catalog and not just to your control file? I've had that situation where we weren't properly syncing (or using) our recovery catalog with new or smaller DBs that we didn't pay much attention to.

Good Luck,
Rich
