11gR2 RAC, ASM and database

Hi all,
I've installed 11gR2 RAC and database on Linux OEL 5.4. Everything seems Ok, I'm able to connect from client using SCAN, and load balancing works well, but "crs_stat -t" shows up some OFFLINE services, like gsd and oc4j.
Is this normal ? If yes, why it's so ? If not, what should I do to solve the problem ?
Thanks in advance.
Antoine

Thanks for your answer.
Those services are disabled, and I've found this one on MOS FAQs :
With Oracle Clusterware 11g Release 2, the GSD resource will be disabled by default. You only need to enable this resource if you are running Oracle 9i RAC in the cluster.

How to configure automatical startup of both ASM and Database

I created a ASM and a database that uses this ASM for file storage management. I also edit the /etc/oratab file as followings:
+ASM:/u01/app/oracle/product/10.2.0/asm:Y
orcl:/u01/app/oracle/product/10.2.0/db_1:Y
However, when I reboot the system, both ASM and database instances cannot be started up automatically.
How can I configure automatical startup of both ASM and Database at system reboot?
Thanks in advance!

try the following
Create file called startdb.sh in $ORACLE_HOME/bin and put following line into startdb.sh and
change the permission of the file with following command.
$vi $ORACLE_HOME/bin/startdb.sh
su - oracle -c 'sh /oracle/product/10.2.0/db_1/bin/dbstart'
Please replace /oracle/product/10.2.0/db_1/ with your ORACLE_HOME
$chmod 777 $ORACLE_HOME/bin/startdb.sh
Open /etc/inittab file and append following two lines in /etc/inittab.
h2:35:once:/etc/init.d/init.cssd start >/dev/null 2>&1 </dev/null
h3:35:wait:/oracle/product/10.2.0/db_1/bin/startdb.sh >/tmp/stdb.out 2>&1
If you have h2,h3 in the inittab file please feel free to change it to h4,h5 or whatever is unique, but it has to be unique name
Please replace /oracle/product/10.2.0/db_1/ with your ORACLE_HOME.
Reboot machine and check out whether both instances are getting started or not.Please check $ORACLE_HOME/startup.log for more information.

How to migrate data from oracle 9i database to new machine 11gr2 RAC ASM

Hi Expert
I need your expertise to advise me what is the best method to move data from oracle 9i database to new machine running oracle 11r2 RAC database with ASM.
Currently my production server running on HPUX ORACLE 9I database with normal file system. My new server is running SUN SOLARIS SPACR 64 bit ORACLE 11gr2 RAC with ASM. What is best method to move data over so it will be consistent. Any guide can refer.
Regard
William

Hi William,
See the note in metalink Migration of Oracle Database Instances Across OS Platforms [ID 733205.1] to saw the Endian Format of your OS. If is the same you can use the RMAN to convert the database to another OS, if not the only option is using export/import (Transportable Tablespaces).
To upgrade from 9i to 11g, see the note 837570.1 - Complete Checklist for Manual Upgrades to 11gR2.
To migrate your FS to ASM the only way is using RMAN, so see the note - How to move a datafile from a file system to ASM [ID 390274.1].
Hope this help you.

Ruben Morais

11gR2 RAC stability and migration path

We are preparing to go from a 10g Data Guard environment (1 primary and 1 physical standby) to an 11g RAC cluster on Sun M5000s (Data Guard will not be part of the final configuration). We have heard that 11gR2 RAC is not yet mature enough so we are considering going to 11gR1. I'm curious what the general consensus is regarding the stability of 11gR2 RAC.
Also wondering what the best migration path would be. We are considering upgrading the 10g Data Guard databases to 11g and then creating a RAC physical standby database on the 11g cluster for the primary database on the old server. The migration to the new RAC cluster will consist of a failover to the new 11g RAC database and will involve minimal downtime. The 10g Data Guard databases and servers will then be decommissioned.
Thoughts?

You will be surprised if I said Oracle RAC11gR2 seems to be a new version NOT a new realease of Oracle RAC11gR1.
Many new features, surprises, bugs, yes bugs....
I suggest to directly address to Oracle itself , to your support at Oracle , as it seems to be a production DB. DOnt take the risk to decide from this forum , ask oracle experts at your support!
Good luck

ASM and database instance sharing same home. Can i split them?

Hi I am running on 10.2.0.1.0 in a 2 server RAC cluster on linux. ASM and db instance are sharing the same home.
I now need to upgrade my ASM instance and clusterware to 11g, but just want to keep my db at 10g because of some compatability issues ( i will probably still need to upgrade the db to 10.2.0.5.0).
Is there any way i can split my Oracle Home so that i now can upgrade my ASM home and keep my prod DB instance still at 10g?
Thanks again. John

ASM and Databases Instances (best practices)

Hello
Platform AIX 5 TL8,
Oracle 10.2.0.4
Context RAC ASM (2 nodes)
We have 25 Oracle databases working under the same ASM Instance on our RAC. I think that this is too much and split at least by creating a new ASM instance on another RAC environment should be better.
Any comment, advises ?
Bests Regards
Den

Hi Den ,
It is not advisable to have 25 databases in single RAC . Instead of databases , you can also think of creating different schemas in same database.

Oracle 11gR2 RAC VM and SCAN and DNS and /etc/hosts (two) setup questions

Hi,
I am looking forward to setting up two Oracle 11gR2 RAC instances
on my Oracle VM test machine.
I plan on using the Oracle 11gR2 RAC VM template.
I want the final Oracle 11gR2 RAC instances to have SCAN that uses DNS.
The DNS will be pre-installed in the JeOS.
My first simple question about the setup is the following.
In my DNS name file, for example,
/var/named/chroot/var/named/milkyway.univ.db
do I need to provide the racnode1 and racnode2 information,
for example,
# DNS name file (snippet)
myjeos IN A 192.168.1.150
racnode1 IN A 192.168.1.161
racnode1-vip IN A 192.168.1.163
racnode2 IN A 192.168.1.162
racnode2-vip IN A 192.168.1.164
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
Or, can I just provide only the rac-scan information
# DNS name file alternate (snippet)
myjeos IN A 192.168.1.150
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
What I am getting at is the following.
Within the install process, will racnode1, racnode1-vip, racnode2,
and racnode2-vip host names and their IP address be written
to the RAC instances /etc/hosts files? (So I should not bother
to put them in the DNS name file like '# DNS name file alternate (snippet)'?)
Or, should I put the racnode and racnode-vip host names and IP addresses
in the DNS name file like '# DNS name file (snippet)'?
The second question is the following.
Are the cluster name and the scan name allowed to be different?
Currently, I would plan them to be different,
for example, rac-cluster and rac-scan.
Or, are they required to be the same,
for example, rac-cluster and rac-cluster.
Thank you.

AIM wrote:
do I need to provide the racnode1 and racnode2 information,
Or, can I just provide only the rac-scan information You need to provide all of it in DNS, because other hosts in your network will need to be able to resolve all of the normal, VIP and SCAN addresses for your RAC nodes. We write this data out to /etc/hosts just to reduce the amount of round-trip DNS requests the cluster nodes make for themselves.
Are the cluster name and the scan name allowed to be different?They can be different.

10.2.0.4 to 11gR2 with RAC, ASM and replication

I have two systems needing to be upgraded. These two systems are both a 2-node RAC on solaris 64 bit using ASM. We use multi-master replication to keep the two systems in sync.
One goal is to have little or no downtime... ( a few minutes might be ok).
One thing that could possibly happen is that we are getting a new hardware to host one of the system and it could already have 11gR2 on it so it might just be a simple export/import. but for the other system in the replication scheme i'd need to get that upgraded.
Can i use replication two keep my downtime to a minimum? for instance, i could have replication on one system queueing up the changes. Once the other system is upgraded turn it back on and get the two systems synced up via replication. So kinda of like this..
system 1 with 10g
system 2 with 10g (current users pointing here)
introduce new system with 11g to replace system 1.
can the changes queued up on system 2 then get propogated to the new 11g system?
and if yes can i then switch users over to the new 11g system, upgrade system 2, then propogate the changes queued up in the new 11g system to the upgraded system 2?
any other advice would be helpful. I haven't seen anything about how replication is effected with the upgrade.
thanks...

Static listener registration 11gr2 RAC Primary and standalone Standby

Hi Guys,
I have to build up a single instance Physical Standby(Dataguard) for a primary RAC (11.2.0.1).The concern or rather confusion we have three SCAN LISTENERS across 2 node cluster,in order for me to have static registration for duplication of database for standby i need to have it put in the listener.ora .
Do i have to create the static listeners for default listener as well as the scan listeners?

My understanding is No.
The Oracle instance would automatically register the local listener to SCAN listeners, so I believe just the default needs this.
This document has Scan listener example and none of them use a _DGMGRL

RAC, ASM and Dataguard compatibility

We have a Dataguard setup with 3 node RAC. The primary is a 3 node RAC but the standby is a single instance. The ASM version is 10.1. Currently we have switchover the roles.
Can upgrade the ASM to 10.2 on standby then make it primary?
All I want to know is if we can have ASM 10.2 on primary and ASM 10.1 on physical standby?

The note for latest ASM [ 10.2 ] indicates a level of backward compatibility I believe
What version is the database ?

Infrastructure for installing advanced features like RAC, ASM and DataGuard

I have been working in Oracle for an year now and would like to start working on advanced features like ASM, DataGuard and RAC. Currently I use a 32bit laptop with OEL6.3 installed with 4GB RAM. Is this system sufficient to install and practice ASM, DataGuard and RAC. To be more specific I would like to know whether 32bit would suffice OR I need a 64bit system for this?

I'd say you are pushing it.
These features are usually used in multi-server environments.
You could work with multiple VM's, but 4 GB sounds very limited.
I had a quick look at introduction to the Data Guard Hands On Lab, and it seems it's hosted in the Amazon Cloud.

What this tells me is, after the reboot, CRS/ASM is coming up and at the same time DB is also trying to come up and resulting in error.
Question is:
Where can I put a sleep 90 or 180 so that DB will come only after ASM is completely up. We didn't write or create any startup scripts for AIX, what ever is there is coming from Oracle 11g Grid and ORacle 10g Database.
Can some one please point me where I can find those init scripts and where i should either put sleep or dependency so that they don't collide.

Separating ASM home and DATABASE home?

I just installed a new 2 node cluster on linux Itanium and I have configured my CLUSTERWARE_HOME and DATABASE_HOME. We are using ASM for our database storage and I had used dbca to create the ASM instances and when I ran the dbca to create the new ASM instance I used the dbca from the DATABASE_HOME.
I have been told that I should have created an additional home for the ASM instance? Is this correct and is this a best practice for RAC and ASM?
Everything is up and running fine and I and pondering if it is worth reconfiguring so that we can have a separate ASM home?
Is there a good doc out there concerning how to reconfigure the home for ASM once it is up and runnig and my database is currently utilizing it for it's storage?
I know that I would just have to lay down the binariies into a new directory but what alse needs to change? Will this affect how the ASM instances are registered with the clusterware?
What is the real benefit of having them separate? I have been told that you can patch then separately but I don't see the benefit as the db would have to be down anyhow if the ASM instance would need to be patched?
Any suggestions are greatly appreciated.
Thanks.

Hi,
<< Oracle Documentation >>
Keep the following in mind when installing ASM:
When running more than one database instance on a single server or node, it is recommended that you install ASM in its own Oracle home on that server or node. This is advisable even if you are running only one database instance but plan to add one or more database instances to the server or node in the future.
With separate Oracle homes, you can upgrade and patch ASM and databases independently, and you can deinstall database software without impacting the ASM instance.
If an ASM instance does not already exist and you select the OUI option to install and configure ASM only, OUI installs ASM in its own Oracle home.
If you are running a single database instance on a server or node and have no plans to add one or more database instances to this server or node, ASM and the database can share a single Oracle home
If an ASM instance does not already exist and you select the OUI option to create a database that uses ASM for storage, OUI creates this single-home configuration.
Have a look at the following documents:
1) ML NOTE:265633.1 ASM Technical Best Practices
2) http://julian.dyke.users.btopenworld.com/com/Blog/2007_01_01_archive.html

Creating Standby for RAC ASM database using RMAN

We are having a Primary Site of 3-Node RAC ASM and we takes daily RMAN backup with the following script
run
allocate channel c1 device type disk format 'g:\rmanbackup\%U';
backup database;
backup archivelog from time 'trunc(sysdate-1)' until time 'sysdate';
We have configured 3-Node RAC Cluster in Standby site. We have copied the rman backup folder to one of the Nodes in the Standby site.
Request your help to restore the RMAN backup. The backup size is around 200GB. We do not know how to use DUPLICATE DUPICATE option in RMAN as if it is restoring from the Primary Location, then transferring 200GB over the network will not be possible.
We need a solution to restore it directly from the Backup folder available in the DR Server. We are not using catalog.
OS : Windows IA 64-bit
RDBMS : Oracle 10.2.0.4
Storage : ASM
DB Nodes at Primary Site, Node1, Node2, Node3
DB instances at primary site : ORCL1, ORCL2, ORCL3
DB Nodes at Standby Site, Node101, Node102, Node103
DB instances at Standby site : ORCL1, ORCL2, ORCL3
DB Name : ORCL on both the sites.

When you create the standby, you can use catalogued backups, stored somewhere local to your standby servers.
For that, they need to be copied to the standby server, or taken from production there, and after restoring the standby controlfile on the standby server, use rman to catalogue the backups to be used. Then, you can use DUPLICATE... and it will be reading your local backup files.
The directory g:\rmanbackup of your rman script is local to standby servers ?
The docs for this have a lot of details: http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/rcmbackp.htm
