there an option to install oracle grid infrastructure on one node only?just like oracle database one node once you have a second node extend the cluster to 2 nodes and maybe relocate the database to the other node ?or even go for full 2 node cluster

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
mad echanges to /etc/hosts on vmorarac1/2 for 2 new IP address assigned to vmorarac5

152.144.199.184 vmorarac1-vip.pbi.global.pvt vmorarac1-vip

Query is is that all ok to reboot the new node to reflect changes as below and change the hostname to vmorarac2
152.144.199.210 vmorarac2.pbi.global.pvt vmorarac2
192.168.2.32 vmorarac2-priv.pbi.global.pvt vmorarac2-priv
152.144.199.211 vmorarac2-vip.pbi.global.pvt vmorarac2-vip
hostname change in /etc/sysconfig/network
On new node vmorarac5, there is alreay software for RAC DB and GUI cloned from vmorarac1
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'm trying to add the third node to my existing two node cluster. In fact i succeded adding the node but i have the following problem:
-when i start node 1 and 2, everything is ok, but on node 3 startup one of the other nodes fails
-this happens in any combination: start 1 and 3, everything is ok. when i start node 2, node 3 fails

What is expected behavior for VIP on Linux servers? ( 2-node RAC)
1.When entire RAC stack is running, and one node is rebooted or crashed? Will VIP fail over to second node?
2.When one node RAC stack is contained (crsctl stop crs), shutting down RAC stack on remaining node? What happens to the VIP and Scan IP?
3.When RAC stacks are down on both nodes, one node has VIP on (eth0:1), reboot this node. What happens to the VIP?
We see some behavior in scenario 3, but don't know why the VIP was moved to second node as all Oracle processes are down.
I have 2 node 11gR1 running on Unix, I want to add 3 more RAC node to it. What are all the steps involved and should I first add 3rd node and then the 4th node or I should add both at the same time? is there any difference between these two methods?

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 want to find the path between two nodes from oracle Hierarchical Table.
Consider the following case ---
NodeId --- ParentId
=============
1 >>>>>> 0
2 >>>>>> 1
3 >>>>>> 2
4 >>>>>> 3
5 >>>>>> 0
6 >>>>>> 5
Here I want to query in the database table that whether there is a path between node 3 and node 5 ? The previous query you provided work up to root node.
Here my expected result is 3-->2-->1-->0-->5
Again if I query in the table to get the path between 1 and 3 , I want to get the output in the following way -
1-->2-->3
So the query need to work in both the cases. Where root nod can act as an intermediate node or not.
how I can get it ?

I wanted to ask if there was anything that I could be doing to alleviate the workload on the 2 remaining nodes right now? As far as I understand it there is no way to stop users from hitting the database and without my 3rd node to load balance the CPU will continue to be pegged until the end of the day as the users are logging off.
I have the following problem on a 10.2.0.4 Oracle on AIX 1.6..I have 2 RAC nodes as the node # 2 goes down, the VIP migrated correctly to the node # 1, but the listener # 1 do not see the change, and just resolve to the local ip.
The same does not apply in the reverse case, when it drops the node N 1, the listener attends to the fallen VIP node and migrated.The configuration is correct and identical in both nodes, according to the documentation, but I can not find a reasonable answer.

A am new in RAC configuration.I configuring RAC with ASM diskgroup with the external redundency. So now i am facing problem to mount the ASM diskgroup. I am giving the the RAC configuration description below.
1. using two node rac1 and rac2
2. asm disk configuration 3 drive
/dev/raw/raw1
/dev/raw/raw2
/dev/raw/raw3
on both node
3. and i am using vmware to configure the both node asmdisk group
after configuring the os level and oracle clustring , i run dbca to configure asm disk group..so in the create disk screen i have found my previous create 3 disks
/dev/raw/raw1
/dev/raw/raw2
/dev/raw/raw3
so first two disks
/dev/raw/raw1
/dev/raw/raw2
i named it "dg1" then press ok , when i pressed ok a warring is appear that is "could not mount the diskgroup on remote node on rac2 using the connection service rac2:1521:+ASM2. Ensure that the listener is running on this node and the asm instance is registred to the listener. Receive the following error:
ORA-15032 : not all alterations performed
ORA-15063 : ASM discovered insufficient number of disk for diskgroup "DG1"
as the same way i create another diskgroup "fg" for flash recovery area using disk /dev/raw/raw3
so after creating the two diskgroup i saw the two diskgroup is appere in the "diskgroup appere screen" an saw that only one diskgroup is mounted but not second node i.e. rac2 diskgroup is not mounted . What should i do no .
I would like to implement Oracle RAC with 2 nodes for SE Licence. I did a lot when both this nodes with 3 NICs each were plugged at the same switch. Now I have a need to construct a RAC when two nodes will be in separate locations, abot 4 miles from each one. What should I explain to our network administrator he needs to do to implement this solution? I've been told that they can do a FO channel to each location. But don't have exact clear explicaton.
