11g CRS and ASM, 10.2.0.4 database, how to set up RMAN

Hi all, I am fairly green when it comes to RAC so please bear with me. I have a Linux 2 node RAC environment. The servers are lux148 and lux149. The 2 node cluster is running 11g CRS and ASM. The database is 10.2.0.4. It had to be set up this way in order for IBM DataStage to work. The database name is fictrp0. The instances are fictrp01 (lux148) and fictrp02 (lux149). I am trying to register the database with an RMAN catalog. I am under the impression that I need to register the database (fictrp0) not the instances (fictrp01 and fictrp02) with the RMAN catalog. Is this correct? So I log into lux148 and set my environment so the ORACLE_SID=FICTRP0. From the command line I issue the following:
fictrp0:/u01/app/oracle> rman target / catalog rman102/[email protected]
The command returns the following:
Recovery Manager: Release 10.2.0.4.0 - Production on Wed Oct 29 14:05:50 2008
Copyright (c) 1982, 2007, Oracle. All rights reserved.
connected to target database (not started)
connected to recovery catalog database
Is this normal "connected to target database (not started)"? I was expecting to see a DBID=FICTRP0 for the target. If this is typical, how will RMAN know the ID of the database? Should I be trying to register an instance perhaps such as FICTRP01? If so do I need to register both instances (FICTRP01 and FICTRP02)?
Bottom line I am very confused on how RAC and RMAN work together. Any help would be greatly appreciated.

You no need to register the instance,You need to register only the database and database only will have DBID

Patching Strategy for CRS and ASM homes

I'm fairly new to RAC/ASM and haven't performed any patch set upgrades yet. Back in the simple days when I wanted to apply a patch set to a database, say from 10.2.0.4 to 10.2.0.5, I would create a brand new Oracle home ahead of time and apply the patch set to it. I'd name my homes like this:
/opt/oracle/product/10.2.0.4/db1
/opt/oracle/product/10.2.0.5/db1
During the maintenance window I would change /etc/oratab to point the database to the new 10.2.0.5 and complete the database upgrade scripts. The advantages of this strategy:
1 - Less risk installing software as nothing uses the new home yet. If something goes wrong in the install, no big deal. Research the problem and try again without being under the stress of a defined maintenance window.
2 - No need to backup old home for back-out purposes.
3 - Less time required for database to be down during actual patch window since Oracle Installer does not need to run.
Now with CRS and ASM, is there a way to pre-stage a new home for those, but not have them "active" to the node until later during the maintenance window?
For ASM, it seems like it would be possible to treat the same way as database and simply update ASM SID in /etc/oratab
+ASM1:/opt/oracle/product/10.2.0.5/asm1
but I'm not totally confident in that as I'm afraid the CRS home may already have references to the ASM home in the cluster registry.
For CRS, it seems like the home is pretty well hard-wired into the node startup scripts and installing a brand new CRS home will probably disrupt the running CRS home.
Any thoughts about this?

Starting with 11.2 for Grid Infrastructure only "out-of-place" patchset upgrades are supported.

Any thoughts about this?As of 11gR2 the ASM is part of the Grid Infrastructure, therefore it is running from the same home and not recommended to separate them. (although you can do that)
By the way, what is your upgrade path? It could be easier to answer your questions if we knew that as there has been a quite a few enhancements and changes in the upgrade/patching process from 10g to 11g. (even between 11gR1 and 11gR2)

Thanks, David. i thought i had it set correctly in Preferences in L&R. Being i was wearing my suspenders and belt at the same time i went back to L&R, cleared what was there and re-entered same to include unchecking and rechecking Time Format fgor 24-hour time. It works now. Thanks again.

HT5622 We have 3 PCs, 2 iPads, 1 iPhone, a MacBook (and a partrige in a pear tree), how do set up 1 itunes library?

I have an individual appleID (2 PCs, 1 iPad, 1 iPhone), my son has an individual appleID (1 iPad, 1 MacBook), and my daughter has an individual appleID (1 iPad, 1 PC). I would like for us to have 1 itunes library that we sync to network attached storage device hosting the itunes library. I want each of us to access (sync) what we want from the same library. How do I set up itunes to be our media library?

I recently got a macbook and had to transfer all my files from my pc laptop. I don't remember the exact process, but I googled something along the lines of "transferring music from pc to mac" and found some helpful articles on setting up a network between the two computers. I don't know if this would work for the original poster as s/he probably can't get the two computers together, but I used an ethernet cable and turned off the wireless and somehow dragged the files over. It can definitely be done, it was a little time consuming but worth it!

CRS and ORACLE_BASE

In some of the documentation from Oracle, it says not to use the same ORACLE_BASE for CRS and the databases. Then the examples in the oracle manuals and in the books (including Murali Vallath's Oracle10g RAC book, page 207) show the same ORACLE_BASE for the CRS, ASM and databases.
There is one note in the "Oracle Clusterware and Oracle RAC Installation Guide" that says "Because you must change the permissions of all the parent directories of the Oracle Clusterware home directory after installing the software to grant write access only to the root user, the Oracle Clusterware home directory must not be a subdirectory of the Oracle base directory". This seems to indicate it must be a different ORACLE_BASE as well as a different ORACLE_HOME for CRS.
Can anyone tell me if they have encountered issues with having the same ORACLE_BASE for CRS, ASM and the RAC databases if they have different ORACLE_HOME for each?

Thought I did follow the Oracle documentation during several of my testing and implementations (which is reflected in my book). I now tend to treat ASM and CRS as separate homes but outside the release levels.
All the new RAC implementations I follow a different directory layout..
Meaning ORACLE_HOME = /usr/app/oracle/product/10.2.0/db_1 but for crs and ASM I place them directly under product and not at a specific release level.
ASM_HOME = /usr/app/oracle/product/asm or ORA_CRS_HOME=/usr/app/oracle/product/crs or
AGENT_HOME=/usr/app/oracle/product/agent
The reasoning for this is that while you can have multiple versions of Oracle supporting several different databases in a RAC environment, you will only have one ASM and only one CRS set of binaries for a given node. Which means while they belong to a version, may not be 'the' version of a specific database that already exists on the server.
You will notice I still place them under ORACLE_BASE/product for managability purposes because both asm and crs are both Oracle products.

How to get the values from table region and how to set

Hi,
I have a requirement as Seeded Page Having One Table Region having around 8 columns, In That Item Description field is there. My Requirement is I need add one more field for that Region and assign the value depending Item Description.
I will create one new Item in that region and will give name as Item, But how to set the values to Item Depending on Item Description.
Is it possible to through CO Extension, If yes..Pls help how to get it.
Thanks in Advance,
Hanimi

Hi Hanimi,
1. You need to extend the VO, add a new Attribute.
2. In VORowImpl of the extended VO, you can find the getter for your new attribute (example getItem())
3. In this getter method you can write some code like:
if("ABC".equals(getItemDescription())
return "XYZ" ;

SQL Server wants to open properties of wrong database and cannot restore logs of different databases at the same time

We have implemented our own way of logshipping by backing up the transaction logs of all our non-system databases every hour. Then we transfer the backups (before SQL Server 2008 R2 with additional zip and unzip steps) to the second environment where we
restore them only during the night on databases in standby-state (Like this, our developers can access the databases without disturbing the productive system and we can restore the t-logs during night, so not shutting out the developers during the day).
Now since we replaced our hardware in the productive environment, we replaced the hardware in the second environment with the servers from previous productive environment. Same SQL Server 2008 R2, same Service Pack (SP2), same installation procedure. But
since then the SQL Server in the second environment behaves different:
- When the logs of some database "A" are restored, I cannot access the properties of any database, i.e. database "B", I only get the error message "Cannot show requested dialog. (SqlMgmt) Database 'A' cannot be opened. It is in the
middle of a restore. (Microsoft SQL Server, Error: 927)"
- Our logshipping runs multiple instance at the same time, so restoring multiple databases' logs. But since the change, two of the instances fail restoring of datatbases, i.e. "B" and "C" with the error message "Database 'A' cannot
be opened. It is in the middle of a restore.". The jobs guarantee to restore only logs of the database they need to restore, they have strictly separated sets of target databases and only try to restore the databases of their sets.
Before the new installations, we did not have these strange behaviours. But as said, it is the same SQL Server version, the same service pack, and we followed the same installation document but maybe with the small changes in settings. The user the jobs
are running under is a domain admin, the login they use has dbcreator, processadmin, db_owner and db_backupoperator roles. My login on the SQL Server has sysadmin rights and as described similar problems.
Is this problem known or does somebody have an idea where to go looking for?
Thanks, Chris

Hi Christar,
According to your description, after you configuring Log shipping between two database, you remove the hardware from production environment to dev environment, in this hardware, there are saved the transaction logs of your database.
When restoring your database, there will occurs error 927, right?
SQL Server Log shipping allows you to automatically send transaction log backups from a
primary database on a primary server instance to one or more
secondary databases on separate secondary server instances. It consists of three operations:
1.Back up the transaction log at the primary server instance.
2.Copy the transaction log file to the secondary server instance.
3.Restore the log backup on the secondary server instance.
Since you want to move your hardware avoiding copy job, we need to verify if .mdf and .ldf file are not saved in your hardware, or else,
if you move your hardware, you could not open your database in your Primary Server. I recommend you can refer to the following steps.
Full back up your primary database and restore it into the secondary database. It would have been set up as WITH STANDBY ,the databases would read StandBy/ Read Only.
Perform transaction log backups via a SQL Server Agent job running on the primary server instance, save them in your hardware.
In night, you move hardware to your dev environment, you can manually restore these transaction log backups or set up a SQL Server Agent job to restoring them from your hardware.
There is detail about how to configure log shipping in SQL Server 2008R2 step by step, you can review it.

How to set up external hard drive and FCE 4

I am going to buy an external hard drive (firewire 400) and FCE4 but I am not sure how to set everything up.
Where should I load the software, capture to, and save projects?

FCE should always live on your system drive. Use the external as your Scratch Disk. You will select this in System Settings in FCE. I create a folder on the external for my projects and point FCE to it.
Keep your project files on your system drive as well as your autsave vault if you use that. You can put your other files, such as wavefrom caches on the external, though I leave them on my system drive.
Do not partition the drive. Format as OS Extended

Can I just retry the root.sh on the 2nd node? or, do I have to do some sort of cleanup and then retry? Please advise.... Thanks, Adolfo

Are you using raw disk devices for Oracle 11g RAC? You might want to move to ASM. For starters, your version, 11.1 is no longer fully supported by Oracle Corp. You'll need to be on 11.2.0.3 or higher to be supported. The 11.2.0.3 version loses Extended Support in August I think. The 11.2.0.4 version loses Extended Support in January. All of this means your production Oracle RAC database should be on the 12c version by January. And guess what? Oracle 12c RAC does not support raw disk devices.
Since you're starting with this cluster fresh, why not aim for a configuration that will allow you to go forth into the foreseeable future without major configuration changes?
Cheers,
Brian

Can we have separate 10gR2 RAC CRS and 11gR2 RAC CRS homes on same Unix s

We'd like to test the upgrade of our 10gR2 RAC databases to 11gR2 RAC.
We have six databases on the same server and want to install a separate 11g RAC stack (11g CRS, 11g ASM, 11g RDBMS) and upgrade each 10g database from 10g RAC stack on same server (10g CRS, 10g ASM, 10g RDBMS) . Is it ok to have 10g CRS home and 11g CRS home same server? If not, how best to upgrade without buying more hardware?
Thanks in advance,
Lou

In more detail, the main issue/question is whether there can be 2 Oracle CRS homes on the same server i.e. separate 10gR2 and 11gR2 CRS homes residing on the same server for the purposes of (gradually) upgrading all Oracle RDBMS homes from 10g RAC to 11g RAC.
Can there be? What would be the implications for the OCR and voting disk? In our case 10g CRS has OCR and Voting Disk on raw devices. In 11gR2, these would need to be migrated/upgraded/stored in ASM, right?
We have 6 10g rdbms homes in addition to the one 10g CRS home and one 10g ASM home. To upgrade can we
- Install 11gR2 CRS in a separate home (this would now include ASM as well)
- Install 11gR2 RDBMS home
- Upgrade one of the 6 10g databases while leaving the others untouched as 10g databases in the separate 10g CRS, 10g ASM stack?
Any ideas, pointers greatly appreciated.
Thanks,
Lou

Can we run 11g RAC and 12c RAC in the same server?

There is a requirement to run 11g RAC and 12C RAC in the same server for a year or so and then remove 11g RAC?
Current setup:
HP-unix 3 node RAC on 11g R2
4CPU
64 GB RAM
3 TB SAN storage
no ASM
Upgrade setup:
HP-unix 3 node RAC on 12C RAC
8CPU
128 GB RAM
6+ TB SAN storage
ASM
We are asked to use the same server and upgrade Hardware to install and run 12C RAC. What are the implications of running RAC in the same server/nodes?
Thank you for your time!

10.2.0.4 RAC / OCFS2 upgrade to 11g R2 RAC / ASM

We are in the planning phase of an upgrade from 10.2.0.4 RAC on OCFS2 Cluster to an 11g R2 RAC and ASM. Is there documentation that will guide me in the best possible and least problematic direction? I have recently moved into the DBA world from a Senior Developer position so my questions might be fairly beginner and I apologize for that now. What I am thinking I would do is create a new RAID10 partition on our SAN and have my ASM disks there. Once the 11g database is installed and configured my plan was to take the current database out of service, back it up, and then recover to the 11g ASM ... is this possible when coming from OCFS2? Additionally I have found the certification matrix in support.oracle.com but that seems to be only a certification of the database against a specific OS ... is there a certification matrix for the hardware I will be installing this on especially my QLogic Infiniband HCA and the firmware version there on.

Cluster and ASM services doesnt start automatically

Hi,
I have configured a 2 node 10g RAC environment (rac, rac2) in RHEL 4 through vmware.
However the cluster services and ASM services do not come up automatically after server reboot. I have to manually bring it up using ./srvctl command.
[root@rac2 bin]# ./crs_stat -t
Name          Type     Target     State     Host
ora....SM1.asm     application     ONLINE     UNKNOWN     rac
ora....AC.lsnr     application     ONLINE     UNKNOWN     rac
ora.rac.gsd     application     ONLINE     UNKNOWN     rac
ora.rac.ons     application     ONLINE     UNKNOWN     rac
ora.rac.vip     application     ONLINE     ONLINE     rac
[email protected]     application     ONLINE     UNKNOWN rac2
ora....C2.lsnr     application     ONLINE     UNKNOWN     rac2
ora.rac2.gsd     application     ONLINE     UNKNOWN     rac2
ora.rac2.ons     application     ONLINE     UNKNOWN     rac2
ora.rac2.vip     application     ONLINE     ONLINE     rac2
Could someone please guide me as to how these services can be brought up automatically upon every reboot?

Normally all services will start automatically, I am not sure how you installed and configured your RAC.
Here i am giving all options.
Option1:-
Re: CRS auto-start
Option2:-
See the below links.

http://www.dannorris.com/2009/03/12/start-database-services-automatically-after-instance-startup/
Option3:-
if you simply want to start the service upon server reboot, put srvctl
command in rc.local script under /etc directory.
Hope this solves your issue.

Install CRS so ASM can share diskgroups accross instances

I saw a note in a 10.1 document that mentions CRS can be used to allow ASM instances to share disk groups and that this configuration does not require a RAC license if single instance databases are being used.
We have a scenario in our development and test environments where clustered databases are not required but I would like to set up ASM similiar to production for consistency purposes.
Is anyone familiar with this? Is there any difference between this type of CRS install and one for RAC databases?

OK so you start off pretend that you are going to install RAC.
You install the clusterware onto your nodes
Then you install ASM onto your nodes
and create network listeners and ASM instances / diskgroup(s)
Then - you do not install the RAC database
instead you may wish to install a new database home that has RAC linked off and then use dbca to create single instance databases - you put the datafiles on asm by specifying something like +DATA (for the DATA) diskgroup
