Database in RAC

Hi,
Could anybody tell me how could I put an existing database for the APPS in RAC? I run the database on Linux and on that server I have only the database.
thanks,
Paul

you need to know that for RAC databse you need to have 2 servers as a biging then you need to follow note for 10g
Configuring Oracle Applications Release 11i with 10g R2 RAC and ASM
Note:362135.1
and note for 9i
Oracle E-Business Suite Release 11i with 9i RAC: Installation and Configuration using AutoConfig
Note:279956.1

Related to recovery in Physical standby database in RAC

In Physical Standby database all instance involved in recovery processes or any one instance will be their in in recovery mode
If is like this another instance will be for high availabily can any one in forum explain me it will be help full

With your Primary database being RAC, the Physical Standby does not have to be RAC, although, obviously it would be preferred to have scalability as required at a DR site.
Whether your Standby is RAC or non-RAC, the automatic Recovery that is done at the Standby is done by one instance only. It would be applying the ArchiveLogs from all the threads (i.e. instances) of the Primary.
Database Recovery is always done by a single instance.

Adding new database to RAC.

Instance not starting after adding new database to RAC.
CRS-0215: Could not start resource 'xxxxxxxxx.inst'.
PRKP-1001 : Error starting instance db on node host

Hi,
Can you check the tnsnames.ora for this iinstance on the node where you are trying to add the instance.
ex:
LISTENERS_MYRAC =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = inst1-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = inst2-vip)(PORT = 1521))

Which difference parallel database and RAC database

Hi Experts,
I saw some document about parallel database and RAC database.
My boss confused these two product.
which difference between parallel database and RAC database?
does parallel database is a "old RAC"?
Thanks
Jim

RAC is the new name with many features for old depreciated Oracle Parallel Server (OPS).
It was avialable till 8i, since 9i it is called RAC.

Flash back database in RAC

HI, I have a question regarding using the flash back database feature nwhen in a rac environemt...I see in the documentation that when flashing back the database that you will need to us the open database with the resetlogs option in order to flashback. So does the open database resetlogs need to be done for each instance in order to get the instance database open?
Thanks.

See if MOS Doc 819905.1 (How to Enable Flashback for a RAC Database on ASM) helps.
Also MOS Doc 416496.1 (ENABLE FLASHBACK DATABASE IN RAC ENVIRONMENT).

Duplicate Target database for RAC

Oracle Database 11g Enterprise Edition
Red Hat Linux
Hi
I am cloning a RAC database using Duplicate Target Database command. First we need to create one Auxiliary Instance using the init file of RAC source database.
I see the following in the init file,
MDB1.undo_tablespace='UNDOTBS1'
MDB2.undo_tablespace='UNDOTBS2'
What should I specify in the init file of Auxiliary instance for these Undo tablespaces ? I am setting CLUSTER_DATABASE to FALSE since the Duplicate database is a single instance one. Only the Source database is RAC.
I am cloning only SYSTEM, SYSAUX, One User tablespace and the Two Undo tablespaces for a point in time 14 days back. I am skipping all other tablespaces.

Hi Morgan,
Is this correct to specify in the Init file ?
*.undo_tablespace='UNDOTBS1'
here UNDOTBS1 is already UNDO tablespace of one instance as I already mentioned.

Primary database is RAC and Physical standby is single instance

Hello All,
I am using Oracle RAC 11.2.0.3 as primary database, we are going to start using Oracle data guard.
So I am designing my infrastructure and planing to use Oracle 11.2.0.3 Single instance as my physical stand by database.
My question is it feasible to have my standby database as single instance while the primary is RAC?
is it feasible to build my Oracle single instance standby database from the RMAN backup of the RAC primary database?
Is there any restrictions (or any points to be taken into consideration) since my primary database is RAC while the physical standby is Oracle single instance?
in the below link
[http://docs.oracle.com/cd/B28359_01/server.111/b28294/concepts.htm#i1039416]
it was mentioned that primary can be RAC or single and same for standby, but my question is it feasible to have primary as RAC while standby as single instance? or it should be like each others?
The primary database can be either a single-instance Oracle database or an Oracle Real Application Clusters (RAC) database.
Similar to a primary database, a standby database can be either a single-instance Oracle database or an Oracle RAC database.Regards,

My question is it feasible to have my standby database as single instance while the primary is RAC?Yes...quite a common setup.
is it feasible to build my Oracle single instance standby database from the RMAN backup of the RAC primary database?Yes.
Is there any restrictions (or any points to be taken into consideration) since my primary database is RAC while the physical standby is Oracle single instance?No show stoppers.

Upgrade database for RAC

I have 11g standard edition database installed without RAC in a server environment. But, now I have needed to keep this database in RAC. Could I install or upgrade database with RAC environment without re-installation of oracle software/database from the scratch?

depends
you can relink the database home with RAC option on Linux/UNIX platforms: RAC Survival Kit: Rac On / Rac Off - Relinking the RAC Option [ID 211177.1]
but not on Windows
if you already have grid infrastructure (clusterware) configured as Oracle Restart, you can convert it to cluster configuration:
http://docs.oracle.com/cd/E11882_01/install.112/e22489/rem_orcl.htm#CBHEEJAA
otherwise you will have to install it (this can be higher version than your database home)

Need advice regarding physical standby databases in rac environment on orac

need advice regarding physical standby databases in rac environment on oracle 10G r2
I like to have have a Primary ( 10 node RAC cluster ) shipping to a physical standby ( 3 node RAC cluster ) shipping using LGWR .
So I have a lot of questions
1) What will be the performance overhead on the Primay if we are using LGWR SYNC option .
2) Does the overhead depends on the physical distance between primary & physical
3)Do you recommend a seperate private network for shipping logs between primary and standby.
4) I know that DGMGRL supports RAC only from 10g. So are there any know issues are bugs using DGMGRL is RAC environments.
Thanks in advance

Generally you should have same CPU architecture and same operating system but it's not mandatory to have the exactly the same CPU model, the same number of CPU, the same RAM size etc.
Actually starting with 11.1 you don't need to have the same hardware setup: it 's even possible to have primary and standby database on different platforms: http://download.oracle.com/docs/cd/B28359_01/server.111/b28294/standby.htm#i72053.

Differences in creating a Standby database in RAC

Hi All
   SO...: Solaris 11 SPARC 64
   DB...: 11.2.0.3.6 (64 bits)
   My experience regarding creating Physical Standby Databases is restricted in only single instances to single instances. I am reading the book "Oracle Database 11g Release 2 High Availability", but, in parallel, i would like to hear from the experienced DBAs here some opinions and recomendations in how to implement a RAC to RAC solution. Below are my doubts:
   1) In single instance, using RMAN Backup to create the Physical Standby, i have to create manually a static Listener Entry. But in a RAC env, the listener is a resource, so, i have to create that resource in the Clusterware manually, or there is other approach?
   2) I have to create a pfile and start the instance in NOMOUNT mode, but in RAC, i have to start all the nodes in NOMOUNT, or just one node is sufficient?
   3) The archives will be replicated from FRA to FRA. Is this the best approach?
   My main concern is with the Listener and SCAN questions... If you have any considerations, they will be most welcome.
   Thanks in advance.

How to restore a single instance database to RAC (10g) using RMAN ?

Hi all,
I have a single instance database configured using file system in a unique server, so now I need to restore this database using RMAN to a new RAC environment with two nodes and ASM also.
Does anyone can help with this documentation or a link about any information about this restore using rman ?
I tryied found on metalink but threres isn´t this specific case. Only how to convert single instance to 10g RAC, but without how to use with rman information.
System: Windows 2003
Oracle 10g R2
Thanks.

In essense you are really doing nothing more than restoring a backup on a new host. If you want a blow by blow detail of how to accomplish it take at http://www.oracledistilled.com/oracle-database/restore-database-to-another-host-using-rman
In order to write the files to the ASM Disk groups you will use the SET NEWNAME FOR DATAFILE in your restore script. You will also need to create the ORACLE_BASE/admin/<DBSID> structure on all of node. Once you get the database completely restore you will need to edit the SPFILE to include the proper value for the CLUSTER* parameters and each the node specific parameters. Sorry that it is kind of higher level than what you are probably looking for but the link above and what I put here should get you were want to go.

Create database on RAC environment - DBCA hangs on clone database creation

Hi, friends!
I have two vm´s (vmware 2) with OEL 5 installed.
I´ve installed OGI and database software sucessfully. So, my crs stack is working fine in both two nodes.
However, when i use DBCA to create a database in this RAC environment, it hangs when it gets on "clone database creation", about 52% of the progress bar.
My DBCA logs don´t point any error out. It just hangs on..
I wait about 4 hours and it doesn´t move on.
I searched and found many cases like that, including here in OTN. But it seems nobody could find a resolution to this issue.
Is there any bug about OEL 5 and database 11gR2??
More details:
I apllied the patch "p8670579_112010_LINUX" on both OGI installation (before root.sh) and databae software install (also before root.sh).
Everything worked fine.
Sorry for the grammar errors.

you can trace dbca, and you can found witch step is occurs problem.
can you paste here last 15-20 sentence of dbca trace file?

Oracle Database 10g - RAC install

1)
I am trying to install Oracle 10g RAC (for Solaris Operating System (SPARC)) using 'Enterprise/Standard Edition for Solaris Operating System (SPARC, 64-bit) - ship_rel10_sol64_db.cpio.gz' downloaded installation. There is no separate installation for RAC, so I assume this is the right install to use for RAC, right?
Since I don't have cabeling for Interconnect done yet, I tried to install Database/RAC prior CRS installation, but no option has been offered for RAC. Do I need to have clustering software installed first in order to be able to installl Oracle Database RAC?
2)
Why is Oracle Database 10g release 10.1.0.3 patch set (for Solaris Operating System (SPARC)) so large - 648 MB?
Do I need to install 10.1.0.2 first?

Hello,
there's no extra RAC software package, but the option is only offered, if one of the supported cluster layers for the respective OS has been installed before.
10.1.0.3 looks like a complete redesign, but anyway it is a patch, you have to install 10.1.0.2 first.
