Rman cold backup for oracle rac

Hi experts;
I want to create a cold backup for an oracle 10g rac DB.
It has 2 nodes, it's not in archive log, this will be the next step.
But now, I want to backup before to proceed.
My doubts are:
I need to shutdown the both nodes?
If yes:
I need to startup nomount just in one node?
If there any document with this specifics steps?
Thanks for your help.
Al

Cold backups are done with the DB completely shut down.
For RAC the data files are used by all nodes in the cluster.
You need to shut down all instances in the RAC.
Then use your OS utilities or RMAN to do the backup.
Here is an 'Ask Tom' topic that discusses this:

Configuring rman backup for oracle on rac cluster

Hi GURUS
We are buying installation oracle rac on a two node server. We do backup our db using rman and TSM .
Does anyone have any guidance on using TSM scheduled TDP backups with
Oracle RAC multi-node?
More to that, is it possible to have multiple archive log destination?
Any advice would be appreciated.
David

While you can have archives going to different destinations, on different nodes, it is not advisable because if these destinations are not reachable in case of a node/system failure, you have no access to these archive logs.
Actually for easy accesibility it would be better to place the archive logs of all instnaces on shared storage. If you are using ASM and using a FRA disk group, you may want to have your archives go into this location.
NFS mounting filesystems could be slower and may have certain perforamance implications.

Clonning using RMAN Cold Backup?

Hi,
I have a COLD RMAN backup in prod server and now i want to clone test db using this backup through RMAN. I have 2 question regarding this
1) Where do i need to place the prod RMAN COLD backup files in test server?
2) If i ran below command how RMAN will know where did i placed the backup in test server?
In Test Server

User managed coldbkp vs rman cold backup

Hi,
I confused about rman cold backup in no catalog mode while restore the backup.please anyone clarify it.
1,I am not confused about user manged cold backup.I took the backup (spfile,control file,redo file,datafile,password file.)Is it right one?
2,In rman cold backup in no catalog mod, we used backup sets for backup,control file is autobackup is enabled.
The backup set format is not OS format.The backup stored at flash recovery area.
Just assume,
I lost all files(spfile,control file,redo file,datafile,password file.)How to recover that.
I am not able to identity spfile & control file in backupset in flash recovery area.
How to identity the spfile,control file during the restoration?
3,Rman takes the copy of online redo file in cold backup?
If it's not,How to recover the database & in user managed backup,copy of online redo log file is must?
4,What is the difference between dbid & sid?when it is used?
5,Can i specifty format for spfile when i take the backup? can i use trace file(control file ) for restoration?
I read the oracle documents, but I am not understand the above things clearly.please anyone rectify it.

Yes,you are right,but first need SHUTDOWN IMMEDIATE;

If you do not explicitly configured rman then yes it will backup to FRA.
Just assume,
I lost all files(spfile,control file,redo file,datafile,password file.)How to recover that.
First need SET (EXPORT) ORACLE_SID and then
rman target /
startup force nomount;
restore spfile from 'autobackuplocation';
startup force nomount;
restore controlfile from 'autobackuplocation';
catalog start with 'backupandarchiveloglocation';
restore database;
recover database;
alter database open resetlogs;
I am not able to identity spfile & control file in backupset in flash recovery area.
From rman you can execute LIST BACKUP or LIST BACKUP OF CONTROLFILE;
How to identity the spfile,control file during the restoration?
3,Rman takes the copy of online redo file in cold backup?No,RMAN do not backup online logs,due to this do not need.
If it's not,How to recover the database & in user managed backup,copy of online redo log file is must?
If cold backup then you can open database with resetlogs option and online logs will create automatically(if you did not copy this logs)
>
4,What is the difference between dbid & sid?when it is used?
DBID is unique identify database in recovery catalog and using this you can restore controlfile easily.But SID is ORACLE_SID and identify instance.This is environment variable like ORACLE_HOME
5,Can i specifty format for spfile when i take the backup? can i use trace file(control file ) for restoration?
Yes you can identify format manually for spfile. ALTER DATABASE BACKUP CONTROLFILE TO TRACE ... this statement use to getting script for recreating controlfile again.So this is not backup and you can notuse for restoring controlfile.If you do not have a backup of controlfile and all datafilesd available then you can use this statement.
I read the oracle documents, but I am not understand the above things clearly.please anyone rectify it.All these and with all situation clearly explained below doc

RMAN Restore using RMAN COLD Backup!!

Hi All,
I Need to restore a database using rman cold backup taken a month back.
Can i use Duplicate database option until time/scn just like we do for hotbackup or is there any other procedure for cloning/refreshing the database using RMAN COLD BACKUP of source.
Thanks & Regards,
Pdev

This may be used to clone db
connect target sys/sys@<dba>
connect catalog rman/rman@<dba>
connect auxiliary sys/sys<new>
run {
set newname for datafile 1 to 'e:\oracle\oradata\giri\system01.dbf';
set newname for datafile 2 to 'e:\oracle\oradata\giri\undotbs01.dbf';
set newname for datafile 3 to 'e:\oracle\oradata\giri\users01.dbf';
set newname for datafile 4 to 'e:\oracle\oradata\giri\indx01.dbf';
set newname for datafile 5 to 'e:\oracle\oradata\giri\example01.dbf';
allocate auxiliary channel dupdb1 type disk;
set until sequence 2 thread 1;
duplicate target database to dupdb
logfile
GROUP 1 ('e:\oracle\oradata\giri\redo01.log') SIZE 100k REUSE,
GROUP 2 ('e:\oracle\oradata\giri\redo02.log') SIZE 100k REUSE;

RMAN Cold Backup FINAL

We are upgrading our production database in 2 weeks. We will be using datapump to export the source and then import to the new target database. As a final backup before the source export I want an RMAN cold backup to get a consistent point-in-time backup. The database is in archivelog mode. After shutting down and using RMAN to perform the cold backup, I will have to open the database to do the export. So how would RMAN restore the production source database back to the time the database was down if additional archive logs are generated during the export? Would I have to specify a time or SCN or would I have SCN gap issues in the recovery of the source database? This is for the source database that will no longer be used once the import to the target and subsequent ERP upgrades are applied. However, I need to preserve the source for a month or so. I could also continue to take hot RMAN backups after the export is completed, but I need the point-in-time recovery to the exact time of the export. I currently only use online RMAN backups since this is a 24/7 database, but I have a short window to upgrade to the new production database.
Thank you,
Curt Swartzlander
DBA

OIM 9.1.0.2 - Weblogic JDBC Multi Data Sources for Oracle RAC

Does OIM OIM 9.1.0.2 BP07 support Weblogic JDBC Multi Data Sources (Services>JDBC>Multi Data Sources) for Oracle RAC instead of inserting the "Oracle RAC JDBC URL" on JDBC Data Sources for xlDS and xlXADS (Services>JDBC>Data Sources> xlDS|xlXADS > Connection Poll> URL) ?
If yes, is there are any other modifications that need to be made on OIM, or just changing the data sources?

Yes, it's supported. You install against one instance directly of the Rac Server. Then you update the config.xml file and the jdbc resource in your weblogic server with the full rac address. It is documented for installation against RAC. http://docs.oracle.com/cd/E14049_01/doc.9101/e14047/database.htm#insertedID2

Encountered ora-29701 during Sun Cluster for Oracle RAC 9.2.0.7 startup (UR

Hi all,
Need some help from all out there
In our Sun Cluster 3.1 Data Service for Oracle RAC 9.2.0.7 (Solaris 9) configuration, my team had encountered
ora-29701 *Unable to connect to Cluster Manager*
during the startup of the Oracle RAC database instances on the Oracle RAC Server resources.
We tried the attached workaround by Oracle. This workaround works well for the 1^st time but it doesnt work anymore when the server is rebooted.
Kindly help me to check whether anyone encounter the same problem as the above and able to resolve. Thanks.

Problem statement:
ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
*** 03/25/05 07:32 am ***
TAR:
PROBLEM:
Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
While creating the database, customer receives following error:
ORA-29701: unable to connect to Cluster Manager
However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
DIAGNOSTIC ANALYSIS:
It seems that the problem is with libskgxn9.so shared library.
For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:
installActions2005-03-22_03-44-42PM.log:,

For 9.2.0.4 -> 9.2.0.6, install log shows:
installActions2005-03-22_04-13-03PM.log:, [libcmdll.so ->%ORACLE_HOME%/lib/libskgxn9.so 64274 plats=1=>[46] langs=-554696704=>[en]] does not exist.
This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.
WORKAROUND:
Customer is using the following workaround:
cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

Gig Ethernet V/S SCI as Cluster Private Interconnect for Oracle RAC

Hello Gurus
Can any one pls confirm if it's possible to configure 2 or more Gigabit Ethernet interconnects ( Sun Cluster 3.1 Private Interconnects) on a E6900 cluster ?
It's for a High Availability requirement of Oracle 9i RAC. i need to know ,
1) can i use gigabit ethernet as Private cluster interconnect for Deploying Oracle RAC on E6900 ?
2) What is the recommended Private Cluster Interconnect for Oracle RAC ? GiG ethernet or SCI with RSM ?
3) How about the scenarios where one can have say 3 X Gig Ethernet V/S 2 X SCI , as their cluster's Private Interconnects ?
4) How the Interconnect traffic gets distributed amongest the multiple GigaBit ethernet Interconnects ( For oracle RAC) , & is anything required to be done at oracle Rac Level to enable Oracle to recognise that there are multiple interconnect cards it needs to start utilizing all of the GigaBit ethernet Interfaces for transfering packets ?
5) what would happen to Oracle RAC if one of the Gigabit ethernet private interconnects fails
Have tried searching for this info but could not locate any doc that can precisely clarify these doubts that i have .........

Can any one pls confirm if it's possible to configure
2 or more Gigabit Ethernet interconnects ( Sun
Cluster 3.1 Private Interconnects) on a E6900
cluster ?Yes, absolutely. You can configure up to 6 NICs for the private networks. Traffic is automatically striped across them if you specify clprivnet0 to Oracle RAC (9i or 10g). That is TCP connections and UDP messages.
It's for a High Availability requirement of Oracle
9i RAC. i need to know ,
1) can i use gigabit ethernet as Private cluster
interconnect for Deploying Oracle RAC on E6900 ? Yes, definitely.
2) What is the recommended Private Cluster
Interconnect for Oracle RAC ? GiG ethernet or SCI
with RSM ? SCI is or is in the process of being EOL'ed. Gigabit is usually sufficient. Longer term you may want to consider Infiniband or 10 Gigabit ethernet with RDS.
3) How about the scenarios where one can have say 3 X
Gig Ethernet V/S 2 X SCI , as their cluster's
Private Interconnects ? I would still go for 3 x GbE because it is usually cheaper and will probably work just as well. The latency and bandwidth differences are often masked by the performance of the software higher up the stack. In short, unless you tuned the heck out of your application and just about everything else, don't worry too much about the difference between GbE and SCI.
4) How the Interconnect traffic gets distributed
amongest the multiple GigaBit ethernet Interconnects
( For oracle RAC) , & is anything required to be done
at oracle Rac Level to enable Oracle to recognise
that there are multiple interconnect cards it needs
to start utilizing all of the GigaBit ethernet
Interfaces for transfering packets ?You don't need to do anything at the Oracle level. That's the beauty of using Oracle RAC with Sun Cluster as opposed to RAC on its own. The striping takes place automatically and transparently behind the scenes.
5) what would happen to Oracle RAC if one of the
Gigabit ethernet private interconnects fails It's completely transparent. Oracle will never see the failure.
Have tried searching for this info but could not
locate any doc that can precisely clarify these
doubts that i have .........This is all covered in a paper that I have just completed and should be published after Christmas. Unfortunately, I cannot give out the paper yet.

Copper cable / GigE Copper Interface as Private Interconnect for Oracle RAC

Hello Gurus
Can some one confirm if the copper Cables ( Cat5/RJ45) can be used for Gig Ethernet i.e. Private interconnects for deploying Oracle RAC 9.x or 10gR2 on Solaris 9/10 .
i am planning to use 2 X GigE Interfaces (one port each from X4445 Quad Port Ethernet Adapters) & Planning to connect it using copper cables ( all the documents that i came across is been refering to the fiber cables for Private Interconnects , connecting GigE Interfaces , so i am getting bit confused )
would appretiate if some one can throw some lights on the same.
regards,
Nilesh Naik
thanks

Cat5/RJ45 can be used for Gig Ethernet Private interconnects for Oracle RAC. I would recommend trunking the two or more interconnects for redundancy. The X4445 adapters are compatible with the Sun Trunking 1.3 software (http://www.sun.com/products/networking/ethernet/suntrunking/). If you have servers that support the Nemo framework (bge, e1000g, xge, nge, rge, ixgb), you can use the Solaris 10 trunking software, dladmin.
We have a couple of SUN T2000 servers and are using the onboard GigE ports for the Oracle 10gR2 RAC interconnects. We upgraded the onboard NIC drivers to the e1000g and used the Solaris 10 trunking software. The next update of Solaris will have the e1000g drivers as the default for the SUN T2000 servers.

Using Cold Backup for a 42GB database

I plan to have a Cold backup for a 42GB db (v 8.1.6). Since it's size is quite large, i am not sure how to back it up quicker.
I did a trial copy for a 3GB file, it took almost 9 hours to finish.
Please help!!!
Thanks a lot :)
Tracey

I did a trial copy for a 3GB file, it took almost 9 hours to finish.Wouaw, what is your network ?
You can copy the files in local, restart db, and move files on an other drive trough network, like this, the service is not down for a long time.

Any Oracle best practice/standards for inter-DataCente links for Oracle RAC

Hello Oracle Experts,
Am working for a customer to set up Oracle RAC architecture hosting SAP/Non-SAP applications per SLA levels(MC/BC/Standard) specs. Currently my network team needs calculation to arrive at whether we will go for a (1), (2) or (3) 10Gig links for inter DC (Data-Center) for Oracle RAC.. below is additional background:
•     Porting all client SAP/Non-SAP Oracle databases to new 2 data-centers.
•     There will be 10 blades (4x BL680s and 6x BL460s) in each DC (can scale-up/out later on).
•     Clusters architecture to support Extended/Stretched RAC cluster feature
•     Clusters 2-node each(1-datacenter1, 1-datacenter2) and nodes distributed across 2 x c7000 such that no cluster has more than one node in an enclosure.
•     Each node will have - 4 NIC ports ( 2 x public and 2 x private) , 2 dual-port HBA
•     Oracle ASM/ACFS (ASM Cluster File System), Voting Disk, OCR and Database files
•     the versions are Oracle 11g RAC, Oracle 10g RAC and Oracle 9i (for DataGuard/Standby) on RHEL 6 on Proliant Blades (x86) + BladeMatrix
My network colleagues considering using DWDM across the 2 DCs(given the lesser cost?). Am still looking around if there are any Oracle/industry-best practices around this and having a calculation to support that..
Many Thanks in advance..
Regards,
Abhijit

Hi ,
There are no specific set of steps / practices for batch loading contents to ucm . It would be very much dependent on how many contents does the user have to load to UCM and how well the server is configured in terms of performance .
You can get more details from the following documentation link : http://docs.oracle.com/cd/E21043_01/doc.1111/e10792/c02_settings009.htm

Why do we use reverse proxy for Oracle RAC Cluster setup

Hello All,
I got this question lately.. "why do we use reverse proxy for Oracle RAC Cluster setup". I know we use the reverse proxy at Middleware level for multiple security reasons.
Thanks..

"why do we use reverse proxy for Oracle RAC Cluster setup".
I wouldn't. I wouldn't use a proxy of any sort for the Cluster Interconnect for sure.

Scheduled cold backup in Oracle

how to do a scheduled cold backup in Oracle 9i?
somebody plz. help...

Hi, 
 
You need ta schedule a shell script in crontab if you're on Unix, or a bat script in TaskManager if you're on Windows. 
The script shut the database down, copy all files (ctl, dbf, redolog...), and restart db.
