We are in the design phase of a project and wanting to implement a 4 node RAC with a DR site. However to get around some licensing costs, management are insisting that only 1 node be up accepting data at the DR site. In the event of a disaster, the remaining nodes will be switched on.

I am configuring two node RAC on oracle virtual box. Did its mandatory to configure DNS on both nodes before Rac installation? Whats the purpose of DNS in RAC. And if its mandatory did i have to configure DNS on each node separately?

Oracle VM 2 Node RAC cluster
Oracle 11G 11.2.0.3.0
Oracle 11g rel 2 GI
on current 2 node cluster we have GI and RAC db configured Nodes: vmorarac1,vmorarac2
we shutdown vmorarac1 to clone it to vmorarac5
on new node I have changed the hostname to vmorarac5 In /etc/sysconfig/network-scripts/ifcfg-eth0 change ip to new ip and same for /etc/sysconfig/network-scripts/ifcfg-eth1 152.144.199.210,152.144.199.211

addnode.sh is used to add existing node, but as part of pre-requisite configuratoin is there any config step missing
I believe, in a multiple RAC Physical Standby nodes only one node applies the archivelogs to the standby database. How you can find which node is the APPLY NODE using a SQL query?
I know you can veiw this information by querying the standby configuration using DGMGRL but how would you find out this information from a remote client using SQLPlus/PLSQL?
We have oracle database 10g(10.2.0.4) running on AIX 5.1. we have installed 2-node RAC on another server AIX 6.1 . Now we want to migrate our single node database to new 2-node rac environment. how we can move/migrate/cluster-aware our single node database to 2-node rac?

I would like get more details about single node RAC.. What is single Node RAC?..
1). just configure only one server instead of two node... same RAC installation.. cluster installation and shared disk configuration in single server itself.. in future we can add node to this ...
2). in 11gR2 having new feature Single Node RAC.. Multiple instances running on same node and configure using Cluster...
is there any advantage using single node rac(other than online upgrade to full RAC).
i have installed oracle 11g r2 rac with 2 nodes. i want to configure the client side load balancing and server side load balancing. For the client side load balancing the i have configured with the
(FAILOVER=ON) (CONNECT_TIMEOUT=5) (RETRY_COUNT =3).
and to configure server side load balancing i have modified the service as follows:
execute (DBMS_SERVICE.MODIFY_SERVICE (service_name=>'service_name', clb_goal=>DBMS_SERVICE.CLB_GOAL_SHORT);
now i have few questions:
1. for the server side load balancing do we have to configure the REMOTE_LISTENER on each node so that the instance on each node registers with the listeners on other node.
2. if we have 3 nodes does this mean that we have to configure the REMOTE_LISTENER on 3 nodes to register with the listeners on the other remaining 2 nodes.
3. does the listener have to be registered with the vip network address (where the clients usually use to connect).
I newly joined Oracle 11g DB related project.That oracle environment own our customer and we have only limited time and access to that DB.

Is there a way to set this with actual hostname of the server.
I have installed oracle 10g in D drive . The installation says it is successful, without asking the database name or the password . I have followed the steps given in the attached file .
However it is not asking the database name or password ( no configuration set up is appearing for the user to interact with the system ) . So, after installation I can not give the username and password .
I have been reading a lot of documentation regarding oracle services and I have an ok understanding of how they work. However, I have a general question regarding configuring services using Oracle RAC. For instance, if I have a 2 node oracle 11GR2 RAC on a Linux Redhat server. I have an application that connects to a service I have created. I create the service as follows.
srvctl add service -d ORCL_RAC -s APP_SERVICE -r ORCL_RAC1,ORCL_RAC2
The tnsnames contains:
APP_OLTP =
(DESCRIPTION =
(LOAD_BALANCE = ON)
(FAILOVER = ON)
[code]...
My questions are as follows:
1) When I do a 'srvctl status service -d ORCL_RAC', should I see the service running on both nodes of the RAC? Or does it run only one node, then it will fail over to the other when needed?
2) If I have a RAC environment where I see two services created (RAC_SRV1 and RAC_SRV2). I see that RAC_SRV1 is only running on node1 and RAC_SRV2 is only running on node2. There are two applications sharing the same database, one application is using RAC_SRV1 and the other application is using RAC_SRV2. Am I correct in thinking that there is no failover available here? If node1 goes down, the application connecting to RAC_SRV1 will not be able to connect to node2 right?
3) In the case of the scenario in question 2 above, would it be best practise to simply create one service and have both applications connecting to the one service? Could I configure the one service to point connections from one application to node1 and connections from the other application to node2?
we are running Oracle database 11.2.0.3 on RHEL 6.1.

We have to configure Dataguard for our 24x7 critical banking 2 Node RAC database(10.2.0.4). Before proceeding with the configuration we have to make sure what steps we should follow to have minimum or no downtime.
1) Document covering DG setup in RAC environment.
2) We have to perform switchover as well so need its steps too. Either the normal switchover steps would be used or have to stop/start rac services as well.
