PSU level of RMAN Catalog DB version and Target DBs

Catalog DB Version: 11.2.0.2.3
Target DBs : 11.2.0.2.3
Currently our Catalog DB and Target DBs ( 15 of them) are of the same PSU level.
We are going to apply PSU 5 (11.2.0.2.3) on some of the target DBs . Should we apply PSU 5 (11.2.0.2.3) on the Catalog DB first before we apply this PSU on the target DBs?

Hi TeslaMan,
Probably you mean the rdbms version of the catalog is version 11.2.0.2.3.
If you upgrade target databases with a cpu you might need to upgrade the catalog schema to an equal or higher level.
Please check the current catalog schema version with the following sql.
select * from RCVER;Maybe you can create a dummy catalog schema with the patched up rdbms rman cli (maybe you tested the cpu already?) and check the new version with the same sql.

Tycho

RMAN catalog fails to show target database information when in nomount mode

Hello everyone, I am trying to restore a dev. database from its own backup taken a week back. The DB is in noarchivelog mode and recently 2 of the datafiles were removed from the files system and thus the need to restore the DB from its backup. However rest of the files and control files are intact.
Now, when I put the database in mount mode and connect to the catalog then I can see the DB's incarnation;

Hi,
You won't be able to see incarnation information when the DB is in "nomount" since the incarnation is written in the control file. I don't think the catalog has this information.
Anyway, in order to restore datafiles, the instance must be mounted, so you should be OK.
Mount the instance and just restore the datafiles.

How do you plan RMAN backup for small and Large DBs ?

DB version:11.2.0.3/RHEL 5.8
I have 2 scenarios for which I was asked to come up with Backup strategies by the application stakeholders.
I have devised the following strategies . Any comments ?
Scenario 1
===========
I have a large DB of 4TB in size. This DB is very critical and acceptable downtime for this DB is only 30 minutes.My Backup strategy: Incrementally updated Backup using Image copy to FRA
Scenario2:
===========
DB sizes vary from 40gb to 800gb. Acceptable downtime : 1 hour
My Backup strategy : cumulative incremental backup to tape

Only testing you will get the answer.
I've seen many cases the technology is adequate but the procedure is wrong.
Oracle provides multiple ways to perform database recovery.
You need to create recovery scenario for each type of failure. (such as Storage failure, block corrupted, Human errors,etc)
Eg: The User deleted data from a table causing major outage in its application.
What is the procedure to be followed?
The simplest is to restore the data using flashback (based Undo) which can take seconds.
(note: Flashback using undo based does not need feature flashback database enabled).
Believe the main cause of failures in databases today are caused by human error and that sometimes can be resolved simply and quickly.
About Backup/Restore strategies:
"Speed" you usually depends on the hardware resources available to you achieving the desired time.
I can post here a ton of options, but I think your answer will be answered in the tests and procedures (scripts) already prepared to perform this restore.

One 8i instance and two rman catalogs 8i and 8

Can I have a single 8i instance for RMAN only with two catalogs, one for 8i and one for 8.0?

Robert,
Yes you can use a single database for 2 recovery catalogs. You can create 2 different schemas for each RMAN catalog version and each of those schemas can hold a different version of the RMAN catalog.
The only reason I can think that you would need 2 different catalogs is because you have an 8.1.X target and a 8.0.5 target? If so, make sure to have the RMAN catalog be the latest 8.1.x release.
In general, the rules of RMAN compatibility are as follows:
o The RMAN catalog schema version should be greater than or equal to the catalog database version. See "Note 1: 8.1 or Later Catalog Schemas in 8.0 Catalog Databases".
o The RMAN catalog is backwards compatible with target databases from earlier releases. See "Note 2: 8.1 or Later Catalog Schemas and 8.0 Target Databases".
o The versions of the RMAN executable and the target database should be the same.
Note 1: 8.1 or Later Catalog Schemas in 8.0 Catalog Databases
RMAN cannot create release 8.1 or later catalog schemas in 8.0 catalog databases.
Note 2: 8.1 or Later Catalog Schemas and 8.0 Target Databases
Restore operations for an 8.0.4 or 8.0.5 target with an 8.1 or later catalog schema do not work when both these conditions are met:
The target database is mounted or open
You are connected to a recovery catalog
If any of these conditions is not met, then you can use an 8.1 or later catalog schema with an 8.0.4 or 8.0.5 target database.
Note 3: 8.1.6 Catalog Schema and Pre-8.1.6 RMAN Executable
Using a pre-8.1.6 release of the RMAN executable with recovery catalog schema of release 8.1.6.0 or 8.1.6.1 (newly created by 8.1.6 RMAN executable using the CREATE
CATALOG command) requires the following update at the catalog database:
SQL> UPDATE CONFIG SET VALUE='080004' WHERE NAME='COMPATIBLE';

RMAN Backup using Rman Catalog

Hi
can we take backup of oracle9i database using oracle10g RMAN Catalog?
Thanks
With Regards
OH

I guess this is related to backward compatibility support principle. Target database's controlfile and RMAN catalog is synchronized and different version may have different structure and feature. When we need to completely restore an Oracle instance from backup, RMAN catalog must be able to support target database, and it may not be possible if RMAN catalog version is lower than target database. I hope I get the message across.
Pls anybody correct me if I am wrong

RMAN CUMULATIVE LEVEL 0 to tape WORKS BUT NOT LEVEL 1 RMAN

Hi All:
I have this saturation My rman cumulative level 0 to tape works everytime but when I try to do level-1 rman backup it failed and it never works. From the rman log, I posted below, it looks like the MML is having a problem. My question:
1. IF this is only MML problem. Isn't that both level-0 and level-1 will failed? Why only level-1 is having the MML problem not level-0?
2. What is RMAN doing different between level-0 and level-1?
ORA-19502: write error on file "cum1_TNLTST8_9qf8fef5_1_1", blockno 1 (blocksize=51
2)
ORA-27030: skgfwrt: sbtwrite2 returned error
ORA-19511: Error received from media manager layer, error text:
Any suggestion or comment are welcome!

Hi Guys
I have a customer where I am supporting a Veritas Netbackup environment and found similar errors on 3 of their oracle databases during backups. The problem is intermittent and if you keep on trying you will get a successful backup. I am not skilled in Oracle and would like some pointers.
Thanx

Weird RMAN catalog issue

I am on 10.2.0.4, RMAN + RMAN catalog + Data Gurad and I am desporate :)
My db crashed with the following:
ORA-27063: number of bytes read/written is incorrect
SVR4 Error: 49: Disc quota exceeded
A look in the FRA showed that it was 100% full. Archived logs take all of the space. I delete archived logs via OS method and then do delete expired archvied log all. If I am connected to recovery catalog while doing this, Oracle DOES NOT delete archieved logs from FRA (I don't see them on diks, but FRA stays full). If I connect to target only and do not connect to the catalog and do the same thing, FRA gets emptied out. WHY???? Thank you for any input!!!
p.s. Here is my delete archvied log script:
#!/bin/ksh -x
# Script to delete archive logs older then 4 days
find /data/archive/PROD/archivelog -mtime +4 -exec rm -r {} \;
. /data/app/oracle/.profile
export ORACLE_SID=PROD
export DATESTAMP="`date +"%y:%m:%d"`"
rman <<EOF
SPOOL MSGLOG TO '/data/app/home/dba/backup_files/archive_logs/PROD_clear_a
rch${DATESTAMP}.log'
@/data/app/home/dba/scripts/connect_nocat.rman
run {
allocate channel d1 device type disk;
crosscheck archivelog all;
delete noprompt expired archivelog all;
release channel d1;
EXIT;
EOF

hi,
you wrote: +"...Oracle DOES NOT delete archieved logs from FRA..."+
If you try to delete needed files (depends on your retention policy:
show RETENTION POLICY;
report need backup;
restore archivelog all preview summary;
) you may have to use "force" option in the statement. Even if they don't exist on disk, RMAN will throw errors.
What is the output of:
crosscheck archivelog all;
delete noprompt expired archivelog all;
P.S. it's better not to delete oracle files in OS if RMAN handles B&R policy ;-)

Rman backup from lower and higher versions

Hi all,
we have three database one db in 8.1.0.6.0 and another 9.2.0.8.0 and another 10.2 database. Can i backup using 9i rman to lower version 8i and 10G using same catalog created in 9i ?

RMAN catalog and Target database

Hi All,
Please clarify my below doubts.
We have one server "server1" with oracle (catalog database) version 10.2.0.1
I have server "server2", and we have four oracle homes with four oracle users.Each oracle home consist of one database. all database are with 10.2.0.3 version.
All these databases registered with the above catalog database.
1 -> Can we register databases with a lower catalog database.
2 -> Now we are upgrading one database to 10.2.0.5 (in server2), in upgrade step we need to action step -: catalog upgrade. If we run this command actually what will be the result?
3 -> We are upgrading only one database in server2. remaining 3 database are in the version 10.2.0.3, upgrade catalog command will upgrade catalog database to 10.2.0.5 version, am I right?
4 -> Here do I need to run upgrade catalog ?
Thanks,
Asim

Question: Which is better and why....RMAN catalog or Flashback Recovery

Hey All,
Newly testing and reading up on 10g. I am on information overload and would appreciate pro's advice on which to choose and why.
Thanks,
d.

Different things, not necessarily alternative. That is, RMAN catalog is normally (at least should be) on another machine, and does not contain physical backups, but only information about them : physical backups are normally stored on external devices, like tapes.
Flashback Recovery technique is based on Flashback logs in Flash Recovery Area, which is a disk area on local machine, and so cannot be unlimited.
Therefore, Flashback Recovery is much faster than Media Recovery, since you don't need to restore anything, but you have limits in using that : your disks size.
On the other hand, RMAN backups are safer, being physically elsewhere.
See http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14220/backrec.htm#g1023042

Get the current version and level of sp.listitem

I'm using a client script to get sp.listitem from a context.
Everything works and load my item
myCtxtWeb.Load(item);
myCtxtWeb.ExecuteQuery();item.Versions;//doesn't existitem.Level;//doesn't exist
Now i need to know the current version and the previous to compare the modified date between them.
Unfortunately the property doesn't exist and same with property level for having the info if it's approved
Are there a way to have them?

For information, i found the solution
SP.File newsItemFile = targetItem.File;
SP.FileVersionCollection fileVersions = newsItemFile.Versions;
myCtxtWeb.Load(fileVersions);
myCtxtWeb.ExecuteQuery();
if (fileVersions.Count > 0)
SP.FileVersion currentVer = fileVersions[fileVersions.Count - 1];//get current version
if (currentVer.VersionLabel == "1.0")
return "add";
Hope it helps some people

New RMAN catalog in existing EMREP database - new user and tablespace?

Hi all,
I am FINALLY getting "with the times" and trying to get my databases to back up with RMAN. I already have a dedicated server that is running Oracle Enterprise Manager 10g Grid Control, so it already has the OMS database on it, called EMREP. I was hoping to just use this database as my RMAN catalog, is that considered good practice or not?
So assuming this practice is considered OK, I know that I need to create a new user (which I'll just call RMAN) in this database. Would it be best to also create a separate tablespace for this user? I have no idea how big I should expect this RMAN schema to get. I'm sure it all depends on the number of databases I'm backing up, but can anyone give me some realistic size expectations that I could start with?
Any advice/info is greatly appreciated!

I think that the catalog is only applicable if you will have several databases to manage.
If you he will have only one, I dont see necessity to use the catalog, therefore with backups of controlfiles only, you can to execute the tasks of backup/restore/recovery.
But, for catalog creation information, see

DB Version and Patch level

Hi Friends
Where can i see DB2 Version and patch level on ECC 6.0?
For Windows Database : DB2 or DB6??
Patch level?
Thanks
srinivas

Hi Srinivas,
DB6 is a SAP abbreviation for "DB2 for Linux, Unix and Windows" .
The DB2 version and FP level of your database server can be found in SAP transaction ST04 or DBACOCKPIT.
In SM50 you can view the work process traces to display the server and client level
C Running with UTF-8 Unicode
C Running with CLI driver
C
C Wed Oct 21 17:03:27 2009
C DB2 client driver version '09.05.0001'
C Connected to DB2 server type 'DB2/LINUXX8664'
C Connected to DB2 version '09.05.0002'
If you need more detailed information you have to use "db2level" in a DB2 CLP window on the DB server.
Regards
Frank
