RMAN Report

Hi,
I am using ORACLE 10.2 G. I have done the following on my pc :
ALTER TABLESPACE USERS BEGIN BACKUP;
CREATE TABLE NOTBACKEDUP(ID INTEGER, STR VARCHAR(16)) TABLESPACE USERS;
INSERT INTO NOTBACKEDUP VALUES(1, 'ROW 1');
INSERT INTO NOTBACKEDUP VALUES(2,'ROW 2);
COMMIT;
ALTER TABLESPACE USERS END BACKUP;
How do I view RMAN Report ? I need to print that report.
Thanks .

Hi,
I have never used RMAN before, I need to print a copy of RMAN report to show that work that I provided in my question. How do I start RMAN ? and How Do I print that report ? I am still in dilema with respect to above statement.
Take time and try to refer to the below oracle documentation
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup008.htm
Note:- Don't be in hurry

RMAN report need backup

We have an incremental level-1 backup Mon-Sat and cold full backup on Sundays with retention policy of 7 days. While troubleshooting some backup issues (space issue, expired backups) I ran the following commands and trying to understand the output.
RMAN> report need backup database;
RMAN retention policy will be applied to the command
RMAN retention policy is set to recovery window of 7 days
Report of files whose recovery needs more than 7 days of archived logs
File Days Name
100 146 /orahprdidx/hprd/psindex05.dbf
RMAN> report unrecoverable;
Report of files that need backup due to unrecoverable operations
File Type of Backup Required Name
RMAN> report need backup days = 7 database;
Report of files whose recovery needs more than 7 days of archived logs
File Days Name
100 146 /orahprdidx/hprd/psindex05.dbf
RMAN> report obsolete recovery window of 7 days;
no obsolete backups found
RMAN>
I looks like I need 146 days worth of archive log files to recover the psindex05.dbf. If so, what I could do to bring that into the 7 days policy?
The database is fine, I am not trying to recover the database.
This was setup by someone and now I am taking over with minimum RMAN experience.
I appreciate any help in this subject.

The datafile was offline. I guess it was created my mistake and hanging in there. Once I do the cleanup it should go away.

RMAN REPORT OPTIONS

i do not really understand the 'redundancy' option of rman report command.
like the one below:
RMAN> REPORT NEED BACKUP REDUNDANCY 2;
please, i don't understand what the word 'redundancy' means here.
I need help please.
thank you

Think of redundancy as number of full backups.
Redundancy 1 is 1 backup ago.
Redundancy 2 is 2 backups ago.

Rman - "report unrecoverable" concept

Hi
I am readin g a book on rman (rman recipes 11g from APress).
I m not able to understand what is the purpose of "report unrecoverable" command. Book says:
>
Ref: Section 8.3 - page# 229:
You want to identify which datafiles have been affected by unrecoverable operations, since RMAN needs to back up those files as soon as possible after you perform an unrecoverable operation.
Use the report unrecoverable command to find out which datafiles in the database have been marked unrecoverable because they’re part of an unrecoverable operation. Here’s an example showing how to use the report unrecoverable command:
RMAN> report unrecoverable;
Report of files that need backup due to unrecoverable operations
File Type of Backup Required Name
1 full /u01/app/oracle/data/prod1/example01.dbf
RMAN>Could someone please give example of unrecoverable operation(s)? And how could rman/oracle know before hand if such an unrecoverable operation is going to be performed on certain datafile(s)?
Thanks

Thanks A datafile or tablespace are set to unrecoverable if any operation that had been performed (since the last backup taken on these datafiles) on datafile or tablespace that are unrecoverable.
A little explanation:
When ever a operation occurs on database i.e. any dml occurs on tables, these operation generates REDO information in redolog files. So when someone explicitly disable the logging information to redologfile(by hint no_logging), then datafile is marked as unrecoverable.
Oracle says it unrecoverable because oracle cannot perform recovery by reading from redologfile or archivefiles if datafile crashes and need a recovery. Thats why rman warns you about such operation which could have taken place and point you to datafile which had these operation performed. The operations which are unrecoverable are:
1) direct load/SQL load
2) direct-path inserts result from insert or merge statement
3) ALTER TABLE commands
4) CREATE and ALTER INDEX commands
5) INSERT /*+APPEND*/
6) partition manipulation
7) database object that has explicitly set with nologging option
8) Oracle eBusiness Suite concurrent job execution identified in Oracle metalink note: 216211.1
8) Oracle eBusiness Suite patches activities that involve database object manipulation
9) SQL*loader with nologging
So once you take the full backup of datafiles (which are affected by these operation) will clearout the Unrecoverable warning. Because now oracle has the backup of these files.
What preventions you can take for not making datafile to Unrecoverable?
Use force_logging

RMAN reports

Hi - need some tips on generating useful RMAN reports. (Not using Recovery Catalog).
SQL> select input_type,
2 round(output_bytes/1024/1024,2) "MB",
3 status,
4 start_time,
5 end_time,
6 time_taken_display "Total Time"

DB INCR 191,63 COMPLETED 15.04.2011 15.04.2011 00:01:05
1 row selected.As you can see this was a incremental backup. But I would like to know what level and what type of incremental backup that was used. I have tried to search through all the v$rman views but cannot find anything that would give me that information.
Is it not possible to get that kind of information from the database views?
Thanks in advance.

You have to cross-check the times with your own backup schedules (e.g. you know when L0 backups are scheduled and when L1 backups are scheduled) OR backup run logs (using the LOG option or capturing the screen output).
Hemant K ChitaleHerman,
I tested tychos's solution (querying v$backup_set_details), and it looks Ok to me?

Unrecoverable_change# and rman report unrecoverable

I am running a test db oracle 11gR2 on windows server 2008.
I am running oracle suggested backup strategy for my backup operation.
So every night i run incremental backup and apply the previous incremental to image copies.
I am confused on why when i run a query like
select file#,name,unrecoverable_change#,unrecoverable_time from v$datafile
i have atleast one or two datafiles whose unrecoverable_change# and unrecoverable_time value is not 0.
Whether the operation was in nologging or not, since i have a incremental backup, why is the above value not 0??
However when i run in rman,
report unrecoverable;
rman does not report anything. So whats the difference b/w rman unrecoverable and the one from v$datafile??
can someone help me understand the correct concept of unrecoverable_change#??
Thanks.

Yes , this is right. At least with Oracle XE as show in following test case:

RMAN report to a table

Hello,
is there a way to create a RMAN report for all the backups that are being done in different databases and that report should be directly writing to a sample table.
the report should contain the colums like -
DBNAME BKPTYPE DATE STATUS STARTTIME ENDTIME .. and so on..
i've tried using some v$views like V$RMAN_BACKUP_JOB_DETAILS,V$RMAN_BACKUP_JOB_DETAILS,V$BACKUP_SET_DETAILS. etc... but i need a some sql or pl/sql that should give me the complete report.
thanks,
vinay

Hi Vinay,
are you using recovery catalog then you can generate the backup report for all databases using the following query.
select
session_key, db_name,
min(r.start_time) start_rman,
min(c.checkpoint_time) start_controlfile,
min(d.checkpoint_time) start_datafile,
min(a.first_time) start_archivelog,
max(a.next_time) end_archivelog,
min(b.start_time) start_set,
max(b.completion_time)
end_set, min(p.start_time)
start_piece, max(p.completion_time) end_piece
from
rman.rc_backup_controlfile_details c
join
rman.rc_backup_datafile_details d
on c.session_key = d.session_key
join
rman.rc_backup_archivelog_details a
on c.session_key = a.session_key
join
rman.rc_backup_set_details b
on c.session_key = b.session_key
join
rman.rc_backup_piece_details p
on c.session_key = p.session_key
join
rman.rc_rman_backup_job_details r
on c.session_key = r.session_key
where
db_key =
(select db_key
from rman.rc_database
where name = 'alice1')
and
c.checkpoint_time >sysdate-14
and
d.checkpoint_time >sysdate-14
and
r.start_time >sysdate-14
and
a.first_time >sysdate-14
and
b.start_time >sysdate-14
and
p.start_time >sysdate-14
and
a.next_time >sysdate-14
and
b.completion_time >sysdate-14
and
p.completion_time >sysdate-14
group by
session_key,
db_name;

OEM and rman reporting

Good Morning.
I've just installed Grid Control 11g, and have it successfully monitoring several of our databases.
One of the pages shows the database RMan backups. Is it possible to get these eMailed out ?
The databases are backed up using RMan, but there is no catalog involved. Is it possible to get the RMan stats out (Such as size, speed, time taken, successful or not from the control file), in which case I should be able to write my own report out, and have these eMailed out..
Thanks in advance

Yes you can get that .
Create a job of type RMAN and then configure email notification for that.

RMAN reporting using SQL*PLUS

I am trying to create a report that will take some of the rman schema views/tables and put it in a specified format for a report. I need to get the database name, start day and time, end day and time, how long the backup took in seonds, the backup status and the number of bytes of the backup. I also need it to span 2 days, i.e 6pm yeterday to 8am today. So far here is what I have:
select a.name,
to_char(MIN(b.start_time), 'MM-DD-YYYY') as "Start_Day",
to_char(MIN(b.start_time), 'HH24:MI:SS') as "Start_Time",
to_char(MAX(b.completion_time), 'MM-DD-YYYY HH24:MI:SS') as "End Day",
SUM(b.elapsed_seconds) as "Seconds",
b.status
from rman.rc_database a, rman.rc_backup_set b
WHERE a.DB_KEY = B.DB_KEY
AND a.DBID = B.DB_ID
AND trunc(b.Start_time) = trunc(sysdate)
GROUP BY a.name, b.status
order by 2,3,1
It only works for the current day and I can't seem to find the byte size for the backup piece. Any suggestions on how this should work I would relly appreciate it.

This is not a right forum to post your problem. This is SQL PL/SQL forum.
Please post it in Database General Forum.

RMAN reporting of Netapp Snapshots

Hi,
The database snapshots taken using Netapp are diverted to RMAN catalog repository. Is there a way, where we can run the reports on which backup is failed/successful using RMAN.

Thanksfor Backup sets and proxy copies the command is: LIST BACKUP : (You can list all backup sets, copies, and proxy copies of a database, tablespace, datafile, archived redo log, control file, or server parameter file.)
for Image copies the command is: LIST COPY : (You can list datafile copies and archived redo log files. By default, LIST COPY displays copies of all database files and archived redo logs. Both usable and unusable image copies are included in the output, even those that cannot be restored or are expired or unavailable.)
for Archived redo log files: the command is LIST ARCHIVELOG (You can list archived redo log files.)
Query the V$RMAN_BACKUP_JOB_DETAILS view for information about the backup type, status, and start and end time. The status column of this view STATUS, This column has One of the following values:
* RUNNING WITH WARNINGS
* RUNNING WITH ERRORS
* COMPLETED
* COMPLETED WITH WARNINGS

Rman :: report backup tag= ??

hello all,
few weeks back i took a full backup of my database using rman and specified a tag like ' %weekly.......%' . Now i dont remember the name of the tag.
how would i find the TAG ?. I checked the TAG column in v$backup_piece, but to no use.
TIA,

but list backup summary did not get me the tag !!How no??

Naturally, my scheduled "delete noprompt obsolete" never seems to remove anything. Any advise appreciated.

Hi,
Please post here the script that you use to perform this backup.
Check if you are using KEEP UNTIL clause.
DELETE OBSOLETE Behavior When KEEP UNTIL Time Expires
If the KEEP UNTIL TIME period has not expired for an archival backup, RMAN does not consider the backup as obsolete. As soon as the KEEP UNTIL period expires, however, the backup is immediately considered to be obsolete, regardless of any configured backup retention policy. Thus, DELETE OBSOLETE deletes any backup created with BACKUP ... KEEP UNTIL TIME if the KEEP time has expired.
http://download.oracle.com/docs/cd/E11882_01/backup.112/e10642/rcmmaint.htm#BRADV89640
V$BACKUP_FILES
KEEP- Indicates whether the backup has a retention policy different from the value for CONFIGURE RETENTION POLICY (YES) or not (NO)
KEEP_UNTIL - If the KEEP UNTIL TIME clause of the BACKUP command was specified, then this column shows the date after which the backup becomes obsolete. If the column is null and KEEP_OPTIONS is not null, the backup never becomes obsolete.V$BACKUP_FILES displays information about all RMAN backups (both image copies and backup sets) and archived logs.

Error while running commands at RMAN prompt

Hi ,
We have a few oracle 10g(10.2.0.3) databases on AIX platform.We use RMAN backup with a recovery catalog database.
The rman full(level 0)backups are scheduled dailly and running fine.When I tried to run commands like 'list backup','report obsolete' I'm getting the following errors.
connected to target database: TICSPROD (DBID=2626621498)
connected to recovery catalog database
RMAN> report obsolete;
RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 3

RMAN-06004: ORACLE error from recovery catalog database: ORA-03113: end-of-file on communication channel
ORACLE error from recovery catalog database: ORA-03114: not connected to ORACLE
But the recovery catalog database is up and running fine.For few other databases I'm able to run the above commands without errors and for some databases I'm getting the errors as mentioned above.
Could someone help me out with this...

Thanks Tycho for your reply.
