Open 10g/11g RAC database in Non RAC Mode

Dear Friends,
How i open 10g and 11g RAC database in Non RAC Mode (open single instance in order to perform upgrade)
Later i will convert the upgraded DB to RAC DB

Regards,
DBEdit spfile and set cluster_database=false before starting database in upgrade mode(optionally you can unset other cluster parameters).
So you upgrade using only 1 instance of database.
Once the upgrade is finished start the other instance as well and set cluster_database=true
Also see preupgrade process - http://docs.oracle.com/cd/E11882_01/server.112/e23633/upgrade.htm#i1011979
Post upgrade -> http://docs.oracle.com/cd/E11882_01/server.112/e23633/afterup.htm#CEGCFJJC

Cloning Oracle APPS Rac Database to Non Rac Databse

Hi all,
I have question.
Presently we are following RMAN duplicate database cloning from RAC asm to (non RAC)non asm database of size 1TB.
If suppose if our databse is 3TB or More. then is there method that we can minimize the cloning time. If so please let me know.
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

Changes between a RAC(Objects) and NON RAC

Hi all,
I want to findout what all the different things to be considered when an application is made to run on RAC env.
For eg: I found there is a difference between the way the Sequences are used in a RAC env from Non RAC.
Are there any guidelines for the Objects used in RAC?
Also can you point me to any doc related to tuning the interconnect as we are identifying wait events related to cluster "Cluster was consuming significant database time"
Thanks.

Hi hyddba,
Absolutely, at database level for application has no changes at objects.
At application code has changes to benefit aplications from failover TAF and FAN events.

I am not sure what you mean by "OS replication".
Whether you use RAC or a Failover Cluster, the database has to be on Shared Storage (which requires no "replication").
RAC licence costs are higher than that for a Failover Cluster because both instances have to licenced and the RAC option has to be purchased.
Of course, if the two nodes together are limited to 4 CPUs, you could consider Standard Edition to reduce the licencing costs.
DBA skills requirements are also higher for RAC.
With respect to your question "...will be sufficient for the avaialability purposes" it really depends on what your requirements are. People use RAC for Avaialability when it really is better positioned for Scalability. If you want only availability and can afford a few minutes downtime, and each node in the cluster can individually handle the user/batch loads, a Failover Cluster would suffice.
I suggest that you raise this question in the "Database - General" forum : General Database Discussions
or the "Real Application Clusters" forum : Real Application Clusters
"Replication" is the wrong forum for such a question.
When you do re-raise your question, please clarify your understinding of "OS replication".

SAN mirroring from RAC production to non-RAC DR

Hi Experts:
My client has a new project using 11gR2 and due to various reasons, they need to do the followings:
- Production Application #1 - 2 UNIX machines (likely AIX) running Oracle 11gR2 RAC, data residing on SAN
- Production Application #2 - 1 UNIX machine (AIX) running Oracle 11gR2 RAC, data residing on SAN
- DR site - Use 1 UNIX machine to host DBs (i.e. all non-RAC) for for both Applications #1 & #2.
Data are replicated from production to DR via SAN mirroring. (Clients decide not to use DataGuard for whatever reason).
I tried to find related info from Oracle website and Metalink with no luck.
Can anyone share there experiences on this , such as:
- Any restrictions or limitations ?
- Can we use only 1 Oracle binaries to host both DBs in DR site ?
- What about fallback from DR site back to the 2 production sites (1 RAC, 1 non-RAC) ?
Thanks and Regards
Airon

- Any restrictions or limitations ? Assuming you are using Same version & release. Of course you can have Different OS,
Here you can either have Normal FILE system, Lets suppose you have RAC on ASM even non-RAC(DR) you can have either on Normal file system (or) ASM file system.
Just take care of size of the mount point of where database resides & archives area size.
- Can we use only 1 Oracle binaries to host both DBs in DR site ?When standby is non-RAC, you have to use only one ORACLE_HOME, Here only Recovery will be in progress, No online threads will be active.
- What about fallback from DR site back to the 2 production sites (1 RAC, 1 non-RAC) ?What that mean? You mean switchover?
before switchover to a physical standby, all but one primary instances should be stopped; after switchover, started again.
http://docs.oracle.com/cd/E11882_01/server.112/e17022/rac_support.htm#i641732
Please describe more on it.
- For the production DB (application #1) with RAC, ASM will be used. So, what files from the 2 Unix servers / SAN must be replicated to DR?
- For the production DB (application #2) without RAC, ASM will not be used. So, what files from the 1 Unix server / SAN must be replicated DR ?I'm not sure for which application you are talking, All the database will be replicated to DR site either SAN or normal.
So you have to build standby database, Check below procedure to achieve this.
Here is document from MAA.
http://www.oracle.com/technetwork/database/features/availability/maa-wp-10g-racprimarysingleinstance-131970.pdf
- In the setup of DR DB server, what type of Oracle installation (need full install of grid + DB software , or just DB software) is needed.In standby you can have just Oracle Home. But cluster_database will be FALSE.
Let us know if any questions.

Rac to Non RAC DAtabase clone

Hi All,
I have a requirement to clone 2 RAC Database to Non-RAC.
Db and Clusterware version --->10.2.0.4
OS version -->OEL 4.6
Nodes in cluster ---> 2
Shared storage type --> ocfs
I have already prepared target server with OS 4.6 linux and database specific settings.
thanks in advance.

on source db:
1. alter system switch logfile; alter database begin backup;
2. Copy all database files (ie. datafile, tempfile, control file, spfile/pfile, redo ... etc) to target server
3. alter database end backup;
On target server:
0. Set cluster_database=false in the pfile
1. Startup mount;
2. alter database datafile '<datafile>' end backup;
3. alter database open;
if you want to rename datafile & rename database, you need to recreate control file.

RAC enabled database binaries vs non-RAC enabled binaries

We have a 5 node cluster in which we will be installing Oracle database binaries onto and creating Oracle databases on, some of which will be standalone and most of which will be RAC enabled.
Is there a difference in 10g RDBMS binaries that are "cluster enabled" versus a single node 10g binary install? Can non-RAC enabled databases use the same set of RAC enabled database binaries? I don't want to install two Oracle home's....
Hopefully that question makes sense. Thanks in advance for your input.

Well, this is a RAC database on AIX so not sure whether checking only libknlopt.a is enough on AIX.
I did not good answer from Oracle support also regarding same question.
I know, if I have RAC DB Binary installed and want to convert to Non RAC, you compile with rac_off option or even set cluster_database to false.
While confusing part is whether Reverse is TRUE i.e. if you have NON RAC DB Binary and then you relink with rac_on option and now you have RAC enabled true. I am not clear on this statement.

Can we put RAC database in Archivelog mode without shutting down

All,
Can we put RAC database in Archivelog mode without shutting down.
Currently our new production database (2 node RAC) is in no archive log mode, Need to enable archive log in the database...
I believe we need to set the cluster_database=false and then put the DB in archive log mode then we need to bounce the database to take effect...
Just curious to know in 11gR2 ...Can we put the RAC database in archive log mode without any downtime ...?

Even RAC or non-RAC, database should bounced and enable/disable archive log mode from mount status.

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.
Virender

Hi Hemant,
I know the v4recovery_log option to check the next archive.
ut below is the situation m facing.

Datagaurd swithover from rac to non rac.

Hello Team,
1.we have created single DR db for the RAC primary database, and we need to perform a swithover to the DR from RAC by DGMGRL, in this case how can we place an entry for both listeners for automatic restart by DGMGRL during the switchover activity ?
2.in this case which one better performing maunal switchover on sql prompt or by DGMGRL ?
3.do we need shutdown one instance during switchover to non rac or will be automatically taken care of DGMGRL???
4. once the non rac converted to primary which rac instance will be applying the logs on RAC standby from non rac?? No oracle docs saying this clearly pls help.
Thanks in advance.

Thanks victor,,,
almost 400GB,
one more, we did a switchover in sql from rac to Non rac (test setup), so after switching over the single node DR start using/following a thread1 redo's and log sequence, in such a case the rac become standby now and we started only instance 2 on rac and placed it on recover mode now, and its start applying logs from the single DR now,so can we start a another rac node also and place it on recover mode? is it possible,or do we need to disable any online log thread or standby log thread on new primary (single DR node) ???
also we can see the new primary control file says still some of archived log not applied, also the rac standby control file says now, there are two log file still not applied but those are in disk now... but during a switchover we followed below method and all completed successfully. the way only we confusing rac to single. all online log file and stand by redo on use for both the threads, pls help. why its showing below not applied.
from new Primary.(non rac)
