Add another instance to RAC database...

Dear all,
If u want to add another instance to database... using dbca ... database should be shutdown or running....?
Please help.
Regards,
Imran

Perhaps asking the question in the RAC forum might be more useful.

But - if you think about it ... the idea of RAC is to maintain ultra high availability. It would sort of defeat the purpose to shut down all RAC nodes to add or remove one node from the database.
(In other words the other nodes can, and probably be should be, up.)
The proper steps to add a node, in general, are
- Install and configure OS and hardware for new node.
- Add Oracle Clusterware to the new node.
- Configure ONS for the new node.
- Add ASM home to the new node.
- Add RAC home to the new node.
- Add a listener to the new node.
- Add a database instance to the new node.
The details are in the Oracle® Database Oracle Clusterware and Oracle Real Application Clusters Administration and Deployment Guide
The real kicker is that the clusterware is installed correctly and it recognizes the other nodes. Also means that the shared store is properly configured, and that is a step people often mess up.

Button makes subform visible, then adds another instance

Hello,
I have a button which makes a subform visible. That is working fine.
I'd like the button when clicked a second time to add another instance of the same subform. Is this possible? I have no idea how to begin with the JavaScript for this and would appreciate help.
Thanks in advance,
MDawn

Instead of making the subform visible and then adding instances you can do it just using instances then the button is doing the same thing.
To "hide" the subform using instances, make sure under Binding that the Min Count is clicked off and the Inititial Count is set to 0 (zero) - your subform will now be hidden by default.
Change the code you have showing the subform to use addInstance() instead of presence, using the underscore shortcut for the Instance Manager (you have to use the underscore method because the instance doesn't exist yet):
_hiddenSubform.addInstance(true);
If you remove instances back to zero then the subform will go away again. Doing it this way also has the advantage of resetting all the data in the subform.

Need for separate instance on RAC database 11g

Hi Experts,
Currently we have a RAC 11g database with two instances. Our business is requesting to create one more instance with an user to store historical data. They claim that they need this separate Instance for the following reasons
1)     Easy backup and recovery for a specific instance in case of historical data
2)     Point-in-time recovery is possible
3)     If any other node fails, then it won’t affect this instance
Please share your expertise on this regard. Thanks in advance.
Regards,
Richard

1)     Easy backup and recovery for a specific instance in case of historical dataWhat data will that be? If this is a 3rd RAC instance, then it will not make backup easier as the data is in the database (on shared storage media) and that needs to be backed up - the database's data does not reside locally on the instance.
2)     Point-in-time recovery is possibleAgain, I do not see how this is a specific advantage that now suddenly occurs with the introduction of a 3rd RAC instance.
3)     If any other node fails, then it won’t affect this instance Correct - a 3rd instance increases the redundancy in the cluster. It also scales it and provides additional processing capacity.

Can I mount another instance of standby database

1. If I have a RAC physical standby database and instance 1 is mounted and is applying redo, can i mount second instance if I wish for example to perform a backup using rman?
2. If instance 1 is mounted and applying redo can I stop it and start instance 2 and continue to apply redo??
Thank you.
Regards.
Cristina.

1. If I have a RAC physical standby database and instance 1 is mounted and is applying redo, can i mount second instance if I wish for example to perform a backup using rman?Yes as Emre mentioned, you can mount all of the instances in cluster.
2. If instance 1 is mounted and applying redo can I stop it and start instance 2 and continue to apply redo??Redo apply will active only on one node, remaining standby instances will be idle
So you can start recovery any instance where you wish.

So how i can run the new address link You mean that after the restart of teh machine, EM doesn't work? Did you check that whether the service of the EM is running or not?
emctl status dbconsoleIf it shows that the EM is not running then you must start teh service using,
emctl start dbconsoleAnd also check that you are not using DHCP, in case of which EM would keep on crashing since the IP would be changed all the time. For this, you must ensure that you configured EM using a static IP only.

Create one more instance in same database?

Hi All,
Any one can u help me, How can create one more(second) instance in same database.please give the steps My environemnt is HP_UX 11.00 and Oracle 8i.
Thanks in advanz

Legatti and Aryndin are correct.
You are either asking how to create another database with its associated instance on the same server as an existing database
OR
you are asking how to add another instance to a RAC clusered database.
In the first case see the DBA Administration manul which has a chapter on the subject of creating databases. The DBCA utility can be used to do this or you can do it manually.
For the second the existing database must first be installed with the RAC option on a clustered server. There are RAC specific manuals available that cover the steps to add another instance on another node to the database.

Create a Rac Database

Hii
I am testing a rac upgrade scenario and scenario is Create new one node rac database upload data from single instance database to new rac database and later add second node to rac database.
I have followed these steps
1.I have installed Cluster software on Centos node1
2.Create A rac database node1 .Oracle software installed local directory.I can see database in crs resources
3.I have add node2 via addNode.sh from node1 and crs working on two nodes correctly.I can see resources these belongs node1 and node2
4.I have installed only database software on node2
5.I run dbca on node1 and select manage instance add instance and I cant see node2 in available nodes only see node1
6.I run dbca on node1 and select create database I cant see node2 in available nodes again only see node1
7.I run dbca on node2 and select create database I cant see node1 in available nodes too only see node2
Where am I making misktake ?have you any advice ?

It appears you manually installed the DB home on the second node. You need to instead run addnode.sh from the first node's DB home to install the DB binaries on the additional nodes.

ASM in RAC database

I couldn't find this thing any where..
Are there any mandatory initialization parameters that must be set to start ASM instance in RAC Database?

vasu77 wrote:
However, asm_diskstring is really not necessary to be set as it limits the disks for recovery. In most cases, the default value "null string" will be sufficient. It helps to find all disk in operating system that ASM has the read/write access. However, specifying values to it might help you manage the disk group easily as it does not spend much time to find the disks. This can be modified using alter system.Beg to differ. It is often critical that the right diskstring is set in order to ensure that ASM only detects the disks/LUNs/devices that it should be used. Especially as the same set of LUNs will also be used for the OCR and Voting and (possibly even) OCFS2 disks. So you want to make sure that ASM does not "+accidentally+" used LUNs that are not intended for ASM use.
Using ASMLib is one means to "+mark+" disks beforehand for ASM usage... but ASMLib is an optional install (and as far as I know, not included with the EE RAC installation as an option either).

I am using oracle 9i RAC.When I run a query in one instance it is working fine but in another instance of RAC it is giving "ORA-00928: missing SELECT keyword".
I am wondering why it happening in the same RAC.Please suggest me where is the problem.

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?

Phil

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.

Add another listener to database

Hi expert
I have EBS v 11.5.10.2 with Database 9.2.0.6 and on this database I have one listener and all employees connect throw this listener with 1521 port , I am thinking to add another listener with 1531 port in database .
How can the application see the both listener in the same time.
