Install mulutple RAC databases on 2-node RAC cluster

I am installing 5 RAC databases on a 2-node RAC cluster. I have setup SCAN using 3 IP addresses.
Do I have to use SCAN listener for all databases?
When installing the 3 database, I get ORA-12537: TNS connection closed error.
ENV: 11gR2 2-node RH5.x
Thanks!

I have setup SCAN using 3 IP addresses.
Do I have to use SCAN listener for all databases?These 3 scan ip will work for youe all database running under this cluster setup.
you may also use VIP to make connection like 10g.
I get ORA-12537: TNS connection closed error.Appear some connectivity/configuration isue,please try MOS doc contain detail on this.

Multiple databases/instances on 4-node RAC Cluster including Physical Stand

OS: Windows 2003 Server R2 X64
DB: 10.2.0.4
Virtualization: NONE
Node Configuration: x64 architecture - 4-Socket Quad-Core (16 CPUs)
Node Memory: 128GB RAM
We are planning the following on the above-mentioned 4-node RAC cluster:
Node 1: DB1 with instanceDB11 (Active-Active: Load-balancing & Failover)
Node 2: DB1 with instanceDB12 (Active-Active: Load-balancing & Failover)
Node 3: DB1 with instanceDB13 (Active-Passive: Failover only) + DB2 with instanceDB21 (Active-Active: Load-balancing & Failover) + DB3 with instanceDB31 (Active-Active: Load-balancing & Failover) + DB4 with instance41 (Active-Active: Load-balancing & Failover)
Node 4: DB1 with instanceDB14 (Active-Passive: Failover only) + DB2 with instanceDB22 (Active-Active: Load-balancing & Failover) + DB3 with instanceDB32 (Active-Active: Load-balancing & Failover) + DB4 with instance42 (Active-Active: Load-balancing & Failover)
Note: DB1 will be the physical primary PROD OLTP database and will be open in READ-WRITE mode 24x7x365.
Note: DB2 will be a Physical Standby of DB1 and will be open in Read-Only mode for reporting purposes during the day-time, except for 3 hours at night when it will apply the logs.
Note: DB3 will be a Physical Standby of a remote database DB4 (not part of this cluster) and will be mounted in Managed Recovery mode for automatic failover/switchover purposes.
Note: DB4 will be the physical primary Data Warehouse DB.
Note: Going to 11g is NOT an option.
Note: Data Guard broker will be used across the board.
Please answer/advise of the following:
1. Is the above configuration supported and why so? If not, what are the alternatives?
2. Is the above configuration recommended and why so? If not, what are the recommended alternatives?

Hi,
As far as i understand, there's nothing wrong in configuration except you need to consider below points while implementing final design.
1. No of CPU on each servers
2. Memory on each servers
3. If you've RAC physical standby then apply(MRP0) will run on only one instance.
4. Since you are configuring physical standby for on 3rd and 4th nodes of DB1 4 node cluster where DB13 and DB14 instances are used only for failver, if you've a disaster at data center or power failure in entire data center, you are losing both primary and secondary with an assumption that your primary and physical standby reside in same data center so it may not be highly available architecture. If you are going to use extended RAC for this configuration then it makes sense where Node 1 and Node 2 will reside in Datacenter A and Node 3 ,4 will reside in Datacenter B.
Thanks,

Install 11gR2 RAC Database Problem: Invalid source path /.../Datafiles

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 VMs (rac1 and rac2) whose OS are Oracle Linux 5.6 in VMPlayer according to the website http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
I have just finished installing Grid infrastructure and start to install RAC database 11gR2.
I have downloaded 2 files from https://edelivery.oracle.com as below:
V17530-01_1of2
V17530-01_2of2
When I start to install the RAC database using the above 2 files but get the error below:
[ora11g@rac1 V17530-01_1of2]$ ls

[ora11g@rac1 V17530-01_1of2]$ cd database

As we see the output above, the error is Invalid source path /../stage/Components/oracle.jdk/1.5.0.17.0/1/DataFiles.
My questions are:
First, are the files V17530-01_1of2 and V17530-01_2of2 the correct files for 11gR2 RAC database ?
Second, how to solve the issue "Invalid source path /../stage/Components/oracle.jdk/1.5.0.17.0/1/DataFiles" ?
Thanks.

Folks,
Hello. thanks a lot for replying.
I go up one level ( / ) and run the command again as below:
[root@rac1 /]# du --max-depth=1 -h
Its output:

4.9G ./usr
157M ./var

0 ./proc
248K ./root
0 ./sys
117M ./etc
3.3G ./home
3.5M ./opt
25G .
[root@rac1 /]#
As we see the output above, it seems that 25GB disk space is used and /tmp occupies 9GB.
I have remove the files under /tmp but after reboot OS, the same files come up again under /tmp.
Some folks use 12GB for each of their VMs and is enough to install Grid and RAC Database.
My questions are:
Why my VM with 30GB disk space does not have enough disk space to install RAC database ?
Can any folk help to solve the issue ?
Thanks.

How to install 11gR2 RAC on 64 bit linux OS

I am completely new to this topic of RAC and need to be installing and standing up RAC on Linux 64 bit OS . I have good knowledge of installing oracle database ENTERPRISE version 11gR2.
Can you guide me as to how to start. I am looking for leads. Probably we will have 2 nodes.
Thank you very much for helping me in advance

If you are a My Oracle Support (Metalink) user, go check out these two notes created by the Oracle RAC Assurance Team. They are excellent.
NOTE: 810394.1 RAC Assurance Support Team: RAC Starter Kit and Best Practices (Generic)
NOTE: 811306.1 RAC Assurance Support Team: RAC Starter Kit (Linux)
In the Linux note mentioned above there is a link to a Linux Step by Step Instruction Guide. This step by step instruction guide is the best start to finish document I've seen for how to set-up and install Oracle RAC. I believe the guide is written for installing release 11.2.0.2.

How to install oracle RAC 11g on oracle linux 5 using vmware workstation ?

Hello;
I need to Install Oracle RAC 11g R2 with database 11g ( 2 nodes ) but by using vmware workstation ( not server 2) on oracle linux 5-6 .
So any document can help me please ..

OWB paris install on 10g rel1 RAC cluster

We are trying to install OWB paris on our 10.1.0.4 RAC cluster using OCFS. When launching OUI without setting oracle home the OUI prompts to install on both nodes, the install fails because it is trying to use the database oraInventory.
as below
Error in invoking target 'isqlldr' of makefile
'/u01/app/oracle/OraHome_2/rdbms/lib/ins_rdbms.mk'. See
'/u01/app/oracle/oraInventory/logs/installActions2005-07-11_10-28-24AM.log' for details.
Metalink suggested the following:
Note:317510.1
Create a seperate oraInventory folder and oraInst.loc file for OWB and specify the file oraInst.loc as parameter while invoking the installer.
Re-install the OWB in a new ORACLE_HOME i.e altogether in a new location and don't install on top of database ORACLE_HOME.
In addition to new location(ORACLE_HOME), create a new Inventory and inventory location file as follows.
1. Set the new location for installing OWB like
export ORACLE_HOME=/u01/app/oracle/product/owb
ensure that the location /u01/app/oracle/product/ exists.
2. Create a diectory oraInventory inside the ORACLE_HOME
3. Create a file oraInst.loc pointing to oraInventory in $ORACLE_HOME by doing:
echo "inventory_loc=$ORACLE_HOME/oraInventory" > oraInst.loc
Note: the directory oraInventory and file oraInst.loc will be present under ORACLE_HOME
4. Invoke the installer by providing the parmater as
./runInstaller -invPtrLoc $ORACLE_HOME/oraInst.loc
When we do this, the OUI does not prompt to install on both nodes.. how can we work around this?, do we have to install owb on each individual node individually?

Hello.
I had the same problem as you did. But i managed to install OWB on both nodes with user equvalents set and by slightly modifying the steps from metalink as follows:
unset ORACLE_HOME (if it is set)
create owb directory
create oraInst.loc in owb
create oraInventory directory in owb
export ORACLE_HOME=/u01........./owb_1
./runInstaller
(note no command line parameters so it picks up the other node)
Basically if you specify the oraInst.loc it goes tot he oraInventory direct instead of doing checks (one of which for the cluster)
Hope this helps.
Thanks

I had this problem and resolved it by transporting the file to the installation server with the correct ftp datatype (binary).
On page 54 of the install guide (..Server\Oracle_Business_Intelligence\doc\doc\bi.1013\b31765.pdf) that comes with the installation files, there is an instruction to make sure that any ftp activity is done in binary.
This may not have occured with the license.xml file if you use a tool which offers the "feature" of automatic datatype recognition.
Hope this helps.

Hi;
I suggest close your issue here as answered than move your issue Forum Home » High Availability » RAC, ASM & Clusterware Installation which is RAC dedicated forum site.

Multiple databases in one single RAC cluster

Hi, I would like to know if one can have multiple databases running on a single RAC cluster, we have several databases in our shop and would like to consolidate all of them into a single 3-4 node RAC cluster running databases with 10.2 and 11.1 versions.
I am newbie to RAC and would like to get some clarification if anyone has done this, google search comes up with few hits on this topic, so obviously this is not doable.
In our case we have one database supporting critical applications and few other not so critical but are used very extensively between 9-5, so what is the use of RAC if I cannot consolidate all my databases into one cluster, or if I need a separate cluster for each of these critical databases?
I have been all the Oracle docs that keep repeating one database multiple instances and one instance-one machine-one node, they don't even advise running multiple instances on a single node?.
I appreciate any insight.
Thanks.

Can you give more details on how you would setup multiple databases running different versions on a single RAC cluster, I am yet to find any documentation that supports or even elaborates on this topic.You can configure a cluster with 12 nodes. Then, using dbca, configure a dev instance for nodes 1 and 2, a prod1 instance for nodes 3 to 6 and a prod2 instance for nodes 7 to 12.
You also can configure each of these instances for all 12 nodes. And use it on all 12 nodes.
Or, after configuring it for all 12 nodes, you can start the dev instance on nodes 1 and 2, prod1 on 3 - 6 and prod2 on the remaining nodes. If dev needs more power, you can for example shutdown prod2 on node 12 and start another dev instance there.
My issue is with the 2nd option - running more than one instance on the same node or server. Why? Each instance has a basic resource footprint ito shared memory needed, system processes required (like db writer, log writer, sys monitor) etc. It does not make sense to pay for that same footprint more than once on a server. Each time you do, you need to reduce the amount of resources that can be used by each instance.
So instead of using (for example) 60% of that server's memory as the SGA for a single instance, if you use 2 instances on that server you now have to reduce the SGA of each to 30% of system memory. Effectively crippling those instances by 50% - they will now have smaller buffer caches, require more physical I/O and be more limited in what they can do.
So unless you have very sound technical reasons for running more than one instance on a server (RAC or non-RAC), do not.

Install mulutple RAC databases on 2-node RAC cluster
