Recover Oracle10g RAC Database

Hi,
Anyone know whether the below backup and restoration works for oracle10g RAC database. I can;t test it out as i don;t have an development environment. Please correct me if i am wrong.
1.) stop all oracle services running on the server
2.) use dd command to backup the raw partition to tape + backup oracle homes on all nodes
3.) Encountered Media failure, change the hardisks
4.) create the raw partitions
5.) restore the raw partitions backup from tape + restore oracle binaries from tape
6.) startup all oracle services
7.) Done.
Thank You, anyone advice and comments are greatly appreciated..

Many thanks for your responses . I finally got it working . It does not require additionalconfigurational change apart from updating the ocr with oifcfg commands(metalink-Note 283684.1 ) i.e. deleting the old entry and setting he new one .
Where I got it wrong was I did not shutdown the nodeapps (which was not included in the metalink note ) before updating the ocr with oifcfg commands
Thanks ..

Oracle10g RAC Cluster Interconnect issues

Hello Everybody,
Just a brief overview as to what i am currently doing. I have installed Oracle10g RAC database on a cluster of two Windows 2000 AS nodes.These two nodes are accessing an external SCSI hard disk.I have used Oracle cluster file system.
Currently i am facing some performance issues when it comes to balancing workload on both the nodes.(Single instance database load is faster than a parallel load using two database instances).
I feel the performance issues could be due to IPC using public Ethernet IP instead of private interconnect.
(During a parallel load large amount of packets of data are sent over the Public IP and not Private interconnect).
How can i be sure that the Private interconnect is used for transferring cluster traffic and not the Public IP? (Oracle mentions that for a Oracle10g RAC database, private IP should be used for heart beat as well as transferring cluster traffic).
Thanks in advance,
Regards,
Salil

At least crossover interconnect is completely unsupported.

Another RMAN duplicate problem - RAC database to single instance

Hi,
I have a problem with the RMAN duplicate procedure and was hoping someone can help.
I would like to create a duplicate of our production RAC database on a separate, stand-alone, database server on another site. This duplicate will be used for intensive querying by another business unit who I don't want to have access to our production database.
My procedure goes like this:
1. Create a disk (not ASM) based backup of the datafiles and any archived redo logs:
"run {
allocate channel d1 type disk;
backup format '/u02/stage/df_t%t_s%s_p%p' database plus archivelog delete input;
release channel d1;
2. Tar and scp these files to the same location on the stand-alone database server.
3. In the meantime, work has been happening on the production database and further archived redo logs have been generated. I don't really care about these logs for the purposes of the duplicate however, I just want to duplicate to the point of the recent backup. To do this, I run the following SQL to determine the sequence number that I should be duplicating up to:
"select max(sequence#), thread# from v$archived_log where deleted='YES' group by thread#;"
4. Duplicate the production database to the stand-alone database (all the SQL Net stuff is working).
"run {
set until sequence (value returned by above SQL statement);
duplicate target database to XXX;
However, my problem arises because I don't know how to handle the fact that there are two threads. I understand that each thread relates to one of the RAC instances, I just don't know which one to specify for the duplicate. We have a database service which the client application connects through, and that service runs on on or other of the instances. Should I just care about the logs from the instance where the service is currently running?
Am I even approaching this is the correct way?
I look forward to any help that people may be able to offer.
Regards,
Phil

Hi Werner,
Thanks again for your help, there is still something wrong though. "list backup of archivelog all;" shows:

you can see that something is setting the recovery SCN to 569505448 which higher even then any of the archived logs mentioned above. If I select current_scn from the production database, this gives me 569528258 which is closer to the value which RMAN is expecting to recover to than any of the archived redo logs.
Can you think what might be causing RMAN to try to recover to this value? and why does it appear to be ignoring the SET UNTIL SEQUENCE command?

How to drop oracle 10.2.0.4 rac database on RHEL5

Hi,
I am having oracle 10.2.0.4 rac database with ASM configuration on RHEL5. Every week/day i take rman level 0 / level 1 backups by using RMAN into disk. Now i would like to test those backups. For that i need to drop this existing database and restrore, recovery from those backups. My database is configured with asm that is having two disk groups.
DATA for storing data
FRA for archive logs
How can i drop the rac 10.2.0.4 database and restore & recovery database from RMAN backups with asm. Could any one send clean steps for this testing?
Thanks

I asked about instances. Before performing your steps is it mandatory to bring down all the oracle instances. Before droping this database how to deregister these services from clusterware? After recover the database how to register the database services with clusterware?if you want to register/de-register, you need to use SRVCTL in clusterware. commands to ADD/REMOVE from clusterware, refer this below note.

Restore Rac database in another cluster

Hello, I have a rac database in a clusterware compose by two node, for example node_1 and node_2, but now I need to pass the rac database from this original cluster to another that already exist.
I have two idea but I do not know if they are correct. One is create a template from my Rac database, and then in the second cluster create a rac database from it. The second idea is to make a copy of the pfile and level 0 RMAN backup in one node of the second cluster and then restore the database there.
Maybe twice idea are bad or maybe exist a better form to do it. I hope you can help me.

Hi,
Well, I believe that I was not clear in my last explanation.
The hypothetical scenario is:
One database using ASM (database name orcl) , two inatances in two separated servers (nodes serv1 and serv2) and two instances ( orcl1 and orcl1).
In this scenary I lost everything and just have the backups of spfile, controlfile, database and archives.
So the steps to recovery is (using serv1):
1- Create the cluster (install clusteware, create CRS/Vdisk, create ASM instance)
2 - Just install the oracle files in all nodes serv1 and serv2, but don't create the instance orcl1 and orcl2.
3 - restore/recover spfile - rman
4 - restore/recover controlfile - rman
5 - restore/recover database with until clause - rman
After these steps the instance orcl1 will be restored by RMAN in the serv1 and the database orcl was created in the ASM.
But, plese correct if I'm wrong, the instance and database will not be registered in CRS (RMAN not register the instance).
So I need to registry the instance and database with srvctl, doing:
1 - create PFILE in serv1 for orcl1 (that point to SPFILE in ASM) and ORAPWD file.
2 - add the database orcl to CRS
3 - add the instance orcl1 to CRS
4 - add the dependency about ASM and orcl1 from the node serv1 (using srvclt)
But after this I have the instance orcl2 in serv2 to create.
Just the instance, because the binaries already installed and the database was already created.
TO complete I need to do the steps:
1 - Copy/Create PFILE for instance orcl2 in serv2
2 - add the instance orcl2 to CRS (using srvctl add instance)
3 - add the dependency about ASM instance (that exists in server2) and Instance orcl2 from the node serv2 (using srvctl)
4 - create PFILE and ORAPWD file.
The question is, RMAN will registry the instanci and database in CRS?
Another question, the RMAN will create PFILE and registry all instances of the original cluster?
I believe that not for two questions, correct?
Exists another path to restore/recover the RAC in this scenary?
Thanks.

Restore RAC database from non-RAC source - EBS R12.1.1

We have restored (PIT) a RAC database from a non-RAC (but ASM) source and I was wondering if that was a reasonable thing to do.
The reason I ask is that I seem to remember that in the upgrade to R12.1.1 the upgrade driver had a different list of jobs to do when the target was RAC vs when it was non-RAC... so is it possible the EBS R12.1.1 code is different for RAC (meaning we dont have the right code base in the DB since we restored a non-RAC source to a RAC destination)?
Disclaimer - I am NOT a DBA .. just trying to identify some potential problems we are troubleshooting.
Thanks in advance!
EBS R12.1.1
OEL 5
11gR2

We have a RMAN back up of the non-RAC database that was restored and PIT recovered on the RAC database.Is it a full database backup?
The "code" base I am referring to is all the db stored objects for R12 EBS .. database compiled code.Restoring the RMAN backup on the target node is not enough. Have you run AutoConfig or postclone? Does your instance know that this is a a single instance and not a RAC one?
I am nervous that there may be alternate versions of the code to run in RAC vs non-RAC .. for instance I know that some of the ASCP jobs use DBMS PIPES and that can be tricky with RAC and Concurrent Manager.. And when we did the upgrade to R12, pointing it @ RAC generated more and different jobs than when it was not pointed @ RAC .. so SOMETHING was different according to the APPS ADPATCH/ADADMIN utilities.Please explain in details what is the purpose of doing this restore and what exactly you are trying to achieve. What cloning procedure you follow to refresh the target instance?
Thanks,
Hussein

Restoring Back To 10g After A Failed 11g Upgrade Of a RAC Database

I'm testing this out on a small test RAC database. I successfully upgraded it from 10.2.0.4 to 11.2.0.2 but wanted to test the scenario of having to go back to 10g if the upgrade really hosed up. The first recovery attempt seemed to be successful but after bringing the DB down with srvctl, it failed on the next startup saying it needed to be started in upgrade mode. Something from 11g was still in place or the fact that I was trying to restart a 10g database managed by 11g clusterware was the issue. I tried starting the DB from both 10g and 11g environments and got the same result. Even starting each instance individually got the same result.
In all that I tried, I got the usual incarnation and "until time before reset time" messages. I've been doing this all through RMAN without EM or Grid Ctl. As usual, any docs I found have had just a little information and I have to piece my own instructions together from all of them, not knowing for sure it all steps would apply in my situation.
Can anybody point me to a good doc or other resource that might help me out? Many thanks!

Now I have a different issue with apparently the same problem. I successfully did the restore/recover as before but the thing pukes when I open resetlogs at the end. Something, somewhere is still pointing to 11g but I have no idea where or what has changed since the last time I did this. Maybe I've messed things up by doing this multiple times. Here are my RMAN commands:
RMAN> connect target
RMAN> startup force nomount;
RMAN> RESTORE SPFILE TO '+DATA/jimg/spfilejimg.ora' from '/local/oracle/10.2.0/db_1/dbs/c-2526333028-20110915-01';
RMAN> shutdown immediate;
(in a different session, from command line)
% mv /local/oracle/10.2.0/db_1/dbs/initJIMG1.ora.bak /local/oracle/10.2.0/db_1/dbs/initJIMG1.ora
RMAN> startup force nomount pfile='/local/oracle/10.2.0/db_1/dbs/initJIMG1.ora';
RMAN> restore controlfile from '/local/oracle/10.2.0/db_1/dbs/c-2526333028-20110915-01';
RMAN> alter database mount;
RMAN>
run {
restore database;
recover database;
RMAN> alter database open resetlogs;
The errors I get after resetlogs are:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of alter db command at 09/16/2011 09:24:50

This is being done on a small, expendable database for practice. I think I've learned enough about what NOT to do to keep me from getting in this jam to begin with. Any thoughts?

Enterprise User Security (EUS) with Oracle RAC database

Hi all,
i'm experiencing a problem configuring centralized AAA on Oracle OID for Oracle RAC Database.
My environment is:
1) Oracle OID 10g (192.168.15.245 - rh4oidserver.klab.it)
2) Oracle RAC database 11g
I successfull configured a standalone Oracle Database to authenticate user in OID centralized repository, but i'm experiencing different problem to do, with RAC, same things.
In dept:
1) Oracle RAC works correctly and internal user (SYS,Oracle, ecc.) are correctly authenticated and authorizated against database
2) Oracle RAC register himself in OID (see attached snapshoot)
3) I run sqlplus to connect on Oracle RAC using OID users and i get following error: ORA-28030 Server encountered problems accessing LDAP directory service
Using a sniffer, i can see a reset message after SSL handshake (SSL v3 encrypted alert), but i don't undenstand root cause....

Hello bipkary,
what version are you using?

Application v/s RAC database

Hi Team,
Please clear me these doubts
As of now my application connects to the single instance oracle10g database
with IP, port and service
ex: 192.168.2.79:1521:orcl
Fine,
now we have a newly set 2 node RAC setup on RHEL4
how can i connect application to the RAC Database?
i have following scenarios
1. if i connect my application to node1's public ip:port:service
if node1 fails how failover happens2. Is there anything required for the application to explicitly specify for connecting RAC database 2 nodes
if you are not clear with above
my application identifies any single instance oracle database with IP:port:service
how can i make this to work for RAC databaseCan anyone please lighten me on this.
Thanks in Advance
AJ

You didn't post a version and 10g RAC is a different animal from 9i RAC.
A client will always be connected to 1 instance only.
Other than that I recommend you read up on Transparent Application Failover (in a standard install your tnsnames.ora already has been configured for TAF) and on FCF for Oracle 10g. Both are in the Net administrators manual.

Rebuilding RAC database from RAC database

Hi All,
Oracle : 10.2.0.4
OS : Linux
I am rebuilding a new RAC database from different RAC database manually from hot bacckup.
Everthing is ok for me but when we try to recoer the new db it will asks you archs to apply.
It will prompt you for the first arch from any thread , after applying the 1st it will not prompt you without giving next arch sequence no from any thread.
I spent time on it and finally get to know that its an oracle bug .
I just want to know wheather is thr any options for us by which we can know the arch sequence no.
Any suggestions wud b appreciated.
Thanks.

RAC database rman duplication question

When I refresh a RAC test system from production, I use RMAN duplicate. My overall steps are:
backup prod using rman
on test system:
in the init.ora/spfile change parameter cluster_database=false
shutdown test db
startup nomount
use rman duplicate to restore/recover the datafiles
alter database open resetlogs
open the database
shutdown the db
in the init.ora/spfile set cluster_database=true
startup the db with srvctl and it starts up the 5 node RAC - srvctl start database -d TEST
My colleague runs RCONFIG after the database restore and after reading through the Oracle docs, I am not sure whether that is required or not. I thought RCONFIG was to convert a single instance to RAC --which technically is what we are doing....but I thought this was used only when creating the TEST RAC database for the first time, and after everything was configured, you could refresh without running RCONFIG. Anybody have any recommendations/knowledge on this I would really appreciate it. My colleague does not want to run RCONFIG if its not required, but if I am missing some finer point in my method I don't want to say you don't need to run RCONFIG. But I will say, I have cloned RAC for years without RCONFIG. Thanks everyone.

As you said, rconfig is the tool for converting a single instance database to cluster database.
Rconfig creates the configuration for a cluster database, updates the spfile with the necessary changes, adds new redo threads and undo tablespaces for the additional instances.
When you duplicate a database that already has these, it is not necessary to run rconfig.

Unable to startup 12c RAC database, can't open spfile in ASM

hello,
I'm testing 12cRAC database on RHEL5 and need your help to troubleshoot and fix the following issue -
DBCA fails at the end of the configuration to create and startup new RAC database with the following errors
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DATA/TDB1/spfileTDB1.ora'
ORA-17503: ksfdopn:2 Failed to open file +DATA/TDB1/spfileTDB1.ora
ORA-15056: additional error message
ORA-17503: ksfdopn:2 Failed to open file +DATA/TDB1/spfiletdb1.ora
ORA-01017: invalid username/password; logon denied
I also tried executing script (which was created by DBCA) to create the new DB manually and got the same results - it happens during first attempt to start it up using SPFILE after new DB was successfully created (it was started up using pfile)
Clusterware with ASM install was successful, binaries were also installed without issues,
cluster seems healthy, I see correct files within ASM using asmcmd etc ..
got stuck here and need some directions ... very confused by ORA-01017 password error
wonder if anyone had same or similar issues ?
Thank you !

Fixed.
Thank you everyone for suggestions and recommendations -
ASM is accessible using asmcmd and I can see all the DB files incuding spfile, they were created by DBCA, alert log showed same information I posted
After extensive troubleshooting and testing the issue was idedntified and fixed - 'dba' group needs to be the primary group for 'oracle' user, not the secondary one. I suspected that something was not right with 'oracle' user access to asm based on that strange password error. There is more I need to check as the issue and fix with swapping groups seems strange. Secondary group is not enough ti have proper rights ??? my first reaction was - seriously ? wtf ?
Anyway - I need to move one now ...
Thank you again !

How can I have a collective AWR report for RAC database in 10gR2 and 11gR1?

Plz correct me here
awrrpt.sql takes the snapshot at the instance level and incase we have 5 instances we have to take 5 awr reports for a particular period.correct???
If above is true ,any wayout to collect a single collective AWR report for RAC database which includes information on all the instances in Oracle 10g R2 or 11gR1 ?
Thanks in advance
Gagan

I have never come across a way for this. though I can n't say it is not there.
But I guess it may not be feasible too becuase as we know the current AWR report contains data which is specific for one instance.
Various hit ratios, top events, instance effeciency reports.... what not ..
It would be really nice to see something is a new format where it lists values from each instance in a single report.. I guess such a thing Does not exiist as of now.

Question about DBCA generate script o create RAC database 2 node cluster

Question about creating two node RAC database 11g after installing and configuration 11g clusterware. I've used DBCA to generate script to create a rac database. I've set
environment variable ORACLE_SID=RAC and the creating script creates instance of RAC1 and RAC2. My understanding is that each node will represent a node, however there should only be one database with a name of 'RAC'. Please advise

You are getting your terminology mixed up.
You only have one database. Take a look, there are one set of datafiles on shared storage.
You have 2 instances which are accessing one database.
Database name is RAC. Instance names are RAC1, RAC2, etc, etc.
Also, if you look at the listener configuration and if your tnsnames is setup properly then connecting to RAC will connect you to either one of the instances wheras connecting to RAC1 will connect you to that instance.

ORA-20600 error while trying to add RAC database

I'm receiving the following error while trying to add the RAC database in grid control. Any idea?.
ORA-20600: The specified target is in the process of being deleted
This database doesn't exists in targets. But, I'm still unable to add.

Check the metalink Note: Unable To Add Rac Database To Grid Control Getting Error Ora-20600 [ID 1218797.1]
You need to wait for a while and check the status.
