Normally goto [http://www.oracle.com/education/certification] ... then look at the Certification paths menu items and view all certifications and locate it.
From memory it is either:
For properly certiifcated 10g/11g DBA OCP 's : pass 1z0-048.
For others attend one of the associated authorized* 10g/11g RAC training course from oracle university (or possibly selected authorized partners); pass 1z0-048 and submit your attended course for verification.

10g RAC on Solaris 10 containers - Question on Approach

Hi All
To introduce a little, I am trying to set-up 10g RAC (active-active) on Solaris 10 Containers. For the disaster recovery site, I was considering an option for storage replication across datacenters. As I look at the situation where the database could be highly transactional, I wanted to go for this option hoping I might be better able to recover db on dr site if a failure happens and also alleviate some load from the prod servers. In this regard I have a set of questions for which if you could share your experiences, thoughts .. I am sure will help my preperation.
1 Is Oracle Supported on Solaris 10 containers? I believe it is not supported and ofcourse am getting into the certification matrix for this with oracle. Anyways, any work around tried out by anyone ?
2 Which product is better in terms of performance while co-existing and co-functioning with Oracle? Sun Cluster!!! Vertas Cluster!!! any other? I am unable to link to any recommendations from Oracle and hence trying to understand the generic or say standard approach to this.
3 I understand on Prod site, Oracle remains active-active on two node cluster while I will mirror my SAN between Prod site and DR site on a timely basis, while DB is up and running. This mirroring has to be only an asynchronous mirroring for some limitations. I am unsure about my recoverability if we need to switch over to DR. Will I be able to recover the Database to a point when my last mirroring has been completed successfully when I say the mirroring happened while the Prod db is up and running (hot backup type on disk level). Until now I used a cold backup for Storage replication and I was sure to bring it up there. This hot backup kind of attempt is raising unrest and questions about the abilities.. :-(
4 I also have come across a term called federated databases? Is it similar to what I am trying to achieve here? Storage level replocation across data centres?
I know it takes some time to get to the end of it and finally implement it, but your inputs will certainly help me get things straight before I hit this first click. Thanks for all your inputs, advices, suggestions. :-)
Regards!

According to Oracle "Both Oracle 9i R2 and 10g R2 databases have been certified to run in a Solaris Container."
There are references here :- http://forums.sun.com/thread.jspa?threadID=5397695
"Oracle databases (RAC and non-RAC) have been certified to run in a global Solaris 10 Container"
What storage are you using ? (filesystem, ASM ?) Personally I prefer ASM now, but it does depend on the storage platform and backup strategy.
What backup infrastructure do you have ? RMAN backup directly to tape is better than file copy.
For DR standby purposes I would use Dataguard instead of disk mirroring / storage replication. It is much more flexible (e.g can switch direction of replication, do incremental backups from the standby etc).
I would use CRS instead of VCS. CRS is built for the job, and integrates with netca, dbca, etc for service management, and also integrates with Dataguard Broker for standby switchover.

Oracle RAC certification

hi all ,
i have OCA and OCP certification for database administrator 10g , i need to take oracle RAC certification 11g
what is the best scenario should i do .

Your best option would probably be to upgrade your 10g DBA OCP to 11g DBA OCP with exam 050, then move to 11g RAC with exam 058. This way you do not have to complete additional training.

Syllabus for 10g RAC Exam & 10g DBA Track

Hi all,
Can anyone please provide me link from where i got Complete Syllabus for Oracle 10g RAC & 10G DBA Track
Thanks in advance

Oracle 10g RAC : 1z0-048
http://syedracdba.wordpress.com/2008/03/22/preparing-for-oracle-10g-rac-expert-exam-1z0-048/
ACE is recommending the docs.
10G DBA Track: 1Z0-052 and 1Z0-053 exams
Now, for syllabus, I think you too search by google for something like "1z0-048 syllabus" and "1Z0-052" and/or "1Z0-053 Syllabus"
Be aware, you will get many fake links of saying that "we are providing the exam dumps / pass guarantee". Don't and never believe upon them, simply ignore them.
I think your this question may be transferred to [url https://forums.oracle.com/forums/forum.jspa?forumID=459&start=0]Certification forum by moderator after some time.

Oracle 10g RAC VMware support

Is Oracle 10g RAC supported in a production VMware environment yet? If not, what is the hold up? VMware is the standard in the industry now and not being able to virtulize is both costly and not practical.

As the previous responder points out, whilst Oracle does not actively certify its products in VMWare environments, it will provide support provided the issue is already known on the guest OS, or it can be reproduced outside a VMWare environment.
I know of many organisations running VMWare with RAC, including my own although we tend NOT to use it in Production environments. Oracle has many resource management capabilities built in to the RDBMS and the Grid Infrastructure which only work well if Oracle has control of all of the resources on a server.
I guess if you're not satisfied with our responses, you should direct your question to Oracle Support rather than this forum. Certification of VMWare is probably as much (or may be mostly) a business decision by Oracle and us Forum members can't generally explain those decisions.

MULTIPLE USERS 10G RAC ORACLE_HOME INSTALL WITH ASM/CRS

Hi,
We need to install multiple 10g RAC databases on a two node Sun servers. Below is our configuration:
1) Sun Solaris (ver 10) with Sun Cluster 3.2
2) One ASM/CRS install (by 1 OS account)
3) Four ORACLE_HOME 10g database install (by 4 different OS user accounts)
We would like to use one ASM instance for all four databases with appropriate privileges.
OS User:           OS Group
========      =========
oraasm           dbaasm - (ASM and CRS install owner)
ora1           dbaora1 - first db owner
ora2           dbaora2 - second db owner
ora3           dbaora3 - third db owner
ora4           dbaora4 - fourth db owner
I understand that certain privileges need to be shared between ASM/CRS and DB owners. Please let me know the steps to be followed to complete this install.
Thanks in advance.

Hi
Please read that: Documentation http://download.oracle.com/docs/html/B10766_08/intro.htm
- You can install and operate multiple Oracle homes and different versions of Oracle cluster database software on the same computer as described in the following points:
-You can install multiple Oracle Database 10g RAC homes on the same node. The multiple homes feature enables you to install one or more releases on the same machine in multiple Oracle home directories. However, each node can have only one CRS home.
-In addition, you cannot install Oracle Database 10g RAC into an existing single-instance Oracle home. If you have an Oracle home for Oracle Database 10g, then use a different Oracle home, and one that is available across the entire cluster for your new installation. Similarly, if you have an Oracle home for an earlier Oracle cluster database software release, then you must also use a different home for the new installation.
If the OUI detects an earlier version of a database, then the OUI asks you about your upgrade preferences. You have the option to upgrade one of the previous-version databases with DBUA or to create a new database using DBCA. The information collected during this dialog is passed to DBUA or DBCA after the software is installed.
- You can use the OUI to complete some of the de-install and re-install steps for Oracle Database 10g Real Application Clusters if needed.
Note:
Do not move Oracle binaries from one Oracle home to another because this causes dynamic link failures.
. If you are using ASM with Oracle database instances from multiple database homes on the same node, then Oracle recommends that you run the ASM instance from an Oracle home that is distinct from the database homes. In addition, the ASM home should be installed on every cluster node. This prevents the accidental removal of ASM instances that are in use by databases from other homes during the de-installation of a database's Oracle home.

Oracle 10g RAC installation on HP-UX 11.31 for SAP ERP 6.04

Dear experts,
We are trying to install SAP ERP 6.0 EHP4 with Oracle 10g RAC on HP-UX 11.31. Please note that, We are using VERITAS cluster filesystem (CFS) for this purpose and not HP-UX ServiceGuard ClusterFileSystem.
*As per SAP procedure, we have installaed plain plain SAP system with single instance Oracle (ref: Configuration of SAP NetWeaver for Oracle Database 10gRAC guide). Now we are first trying to install Oracle Clusterware (CRS) and then we will install Oracle RAC software. Is this procedure right?*
Which file (and its path) we have to use for CRS installation and its patch? Is it runInstaller under /oracle/stage/102_64/clusterware? With this file we can install CRS 10.2.0.1. Similarly for Oracle RAC, which files we are supposed to use, i.e for installation and patch upgrade?
Also can we use clusterware package available from Oracle directly in the SAP environment?
We tried to install CRS with runInstaller while running Configuration Assistant after root.sh script.
The following commands are failing in Configuration Assistant:
/oracle/CRS/102_64/bin/racgons add_config erpprdd1:4948 erpprdd2:4948
/oracle/CRS/102_64/bin/oifcfg setif -global lan1/20.20.20.0:cluster_interconnect lan0/192.168.3.0:public
/oracle/CRS/102_64/bin/cluvfy stage -post crsinst -n erpprdd1,erpprdd2
1st command does not give any output if run manually.
2nd commands o/p: PRIF-12: failed to initialize cluster support services
3rd commands fails in every check
Please suggest the solution and expecting answers to the above mentioned questions.
Thanks & Regards,
Tejas

Relevant docs for Service Guard (SG) cluster are available at http://docs.hp.com. Hope you have checked for the suport of oracle 92x on HP-UX 11.31

You can go for combined os migration and db release upgrade also at a stretch with the same downtime.

10g RAC on Linux

All,
I am having strange problem while setting up 10g RAC on Linux box. This is two node cluster (rac1 and rac2) Two probelms..
1. When I install CRS on rac1, it copies the files to rac2 and olsnodes -n works fine from both nodes, But when I run runinstaller on node 2 and try to see installed products, I don't see CRS oracle home there on rac2.
2. When I start installing 10g database on rac1 , at third step "Hardware Cluster Installation Mode:" I see my both nodes listed there, but I don't see "SELECT ALL" button on that screen. So when I finish installation, it doesn't copy files to rac2.
Does Anyone has any idea why it is behaving like this?
Thanks
Puneet

Hi,
I found one thing.. If I change ORACLE_HOME location while running OUI, it doesn't give SELECT ALL button , but if I let Installer to select oracle_HOME, it worrks fine and give SELECT ALL button too.
Don't understand why it is behaving like this?

10g RAC on VMWare Workstation

Hi Folks,
i tried to install 10g RAC on VMWare 4.5.2 for testing.
Hostsystem is XP, ghost system are RedHat-ES-30.
I configured tho 2 nodes with 2 scsi adapters and 2 Network Card and a shared Disk.
I installed ocfs 1.0.12 on both nodes, formated the disk and it seems to be fine.
On the next step ( Installation of CRS ) the runInstaller fails after the node configuration screen with the message:
Oracle Cluster Registry File can only be saved on a shared filesystem file or on a RAW Device.
Any Ideas ?
Thanks
Martin

Hi Laurent,
Thanks for your reply.
I checked that and i can't find the Processes or any think else witch is discribed in thr article !
The Installer pops a message during the creation of the ocr file.
Have any body tried it with RAW Devices ?

10g RAC upgrade to 11g RAC

How to perform 10g RAC upgrade to 11g with Dataguard in place?
OS=LINUX
RDBMS=10.2.0.4
DG=PHYSICAL STANDBY
Below is my understanding
1)Install 11g CRS in NEW_CRS_HOME
2)Install 11g in NEW_ASM_HOME
3)Install 11g in NEW_RDBMS_HOME
4)Export the new NEW_ORACLE_HOME and start up the database with startup upgrade.
5) Run the catupgrade.sql script.
Are there any other steps involve?
In case I have to rollback then how to rollback CRS.

Personally I would use DBUA instead of catupgrade.sql, but make sure you follow the upgrade documentation for pre-checks etc. You will also need to use netca to recreate the sqlnet listeners in the 11g homes and register with 11g CRS.
CRS is generally fairly quick to re-install and re-register databases, and this is cleaner than trying to restore OCR and VOTE disks etc. If you prefer to rollback be sure you backup the OCR and VOTE disks (e.g use dd), backup /etc/oracle, CRS_HOME, /etc/init* scripts etc.
The dataguard standby database should roll forward through the upgrade, but you will need to manually register the standby with 11gCRS. Make sure you have your DB and Log create_file_dest's set, as well as standby_file_management=auto. Personally I would manually recover the standby after the upgrade in case I need to use it to fallback.

10g RAC - should I use RAW, OCFS and/or ASM ?

I am about to install 10G RAC on RHAS3. Options for sharing disk partitions are raw, OCFS and ASM. The OCR and voting files must be raw or OCFS, I would tend to go for OCFS in this case. For the Oracle datafiles, again, I would tend to go for OCFS simply for ease of management since ASM seems to add another layer of complexity, and raw lacks flexibility. OCFS however is also new technology and may still have some stability issues. I'm not yet sure of our disk configuration, but there will be HBA cards in each machine with one or two SAN partitions, so I don't expect some of the ASM features such as mirroring etc. will be required as this will be done in the hardware. Does anyone have any recommendations or experiences(good or bad) in which way to go ?
Philip

We're using raw partitions for some years now, (since oracle 8i, then 9i and now 10g). It is quite flexible, but you shouldn't use physical partitions but LVM. It's very stable.
Now on 10g we're using ASM on some sites where mirroring is needed. It works, but not so stable as raw. we discover some bugs as well.
We've never used OCFS. I don't like it. To much limits. I belive that special utilities are needed for managing files. I don't like linux system software produced by oracle.

10G RAC on AIX without ASM & HACMP.

Hi,
I want to install ORACLE 10G RAC on AIX but I dont want ot use ASM or HACMP/GPFC.
Just want to install with CRS and RAW devices.Is it possible to install 10g RAC with CRS and RAW devices.
What is the best approach for this.
Regards
MMU

We're running CRS on AIX. No ASM or HACMP.
We do have the db datafiles on GPFS. We've also got one voting disk on GPFS and two on raw devices.

CRS-0210: Could not find resource while start ASM on 10G RAC

Dear All
I'm trying to install 10g RAC on Redhat 4.1. At the point at which I try to start ASM it fails with the message
ORA-03113: end-of-file on communication channel
select value from v$parameter where name='instance_type'
ERROR at line 1:
ORA-01034: ORACLE not available
This seems to be due to a failure CRS. The trace file shows:

Is this a red herring or is it the reason ASM won't start? At what point should this entry have been created (ie should it already exist when ASM starts or should ASM create it)? Can I manually create the entry using crsstat.
Many thanks
Paul

It all depends on what your mapping problem was and what you did to resolve it. Here are a couple of things you could try:
-Make sure the orc.loc file on ebdb1 has the same entry as ebdb2. Also, say you are using shared raw devices for CRS: make sure your raw devices are consistent on both nodes.
If the above does not work
-Make sure the shared devices are consistent on both nodes and restore one of the OCR backups. I am sure at least one of the backups 4hrs/8hrs/1day/2day/1week some thing must be a worthwhile. If you do restore OCR from a backup make sure to run cluvfy before you start your CRS.
Always a good practise to take a backup of status quo before you restore from the backups.
It would be interesting to know what lead to your disk mapping problem in the first palce.
Good Luck!

Those errors remind me on errors I encountered when I was trying to do installation that was not certified,
so try to check if installation you are doing is actually supported.
