RAC/ASM Clusterware Installation :: Query On Adding New Node To Existing 2 Node Cluster
Jun 15, 2012
current environment
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
152.144.199.171 vmorarac1.pbi.global.pvt vmorarac1
192.168.2.30 vmorarac1-priv.pbi.global.pvt vmorarac1-priv
152.144.199.184 vmorarac1-vip.pbi.global.pvt vmorarac1-vip
[Code]....
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 am installing Oracle 10g Clusterware in RHEL 5 Server. When i run root.sh in the second node the last step Running vipca(silent) for configuring nodeapps failed. Then i run VIPCA manually in second node and configured vip configuration successfully,but when i checked the post-checks for cluster services the Checking existence of VIP node application,Checking existence of ONS node application and Checking existence of GSD node application in second node failed. I am able to ping both the servers one another with vip name successfully and the CSS,CRS and EVM appears healthy in both nodes. 1. Does the vip configuration is proper? If no what is causing this error and how to rectify it? Find the output below

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
The asm configuration (disks, permissions, etc) is the same on all three nodes.find below the asm and crsd log details from the failure time:
alert_ASM.log

I have a 3 node RAC server on Windows Server 2008. Last week the hard drive went out on one of the nodes and I have had to rebuild as I could not recover anything.
I went through and deleted the old node and now I have just finished adding the new node back to my cluster via documentation. Once I created the new instance on that server DBCA attempted to start and it failed gaving me a crs error. I found out later that the other 2 nodes went down and the new one that did not start correctly was the only one up!! I went and stopped the new instance and restarted the first 2. The associated services did not start with the instance so I had to start each manually. The trace files show an ORA-29702 error with cluster group service and the instance being stopped on both of the existing nodes. No other error messages stood out.
Now I cannot get any crs services to start on that 3rd node even if I attempt to start manually. I have also tried stopping all and restarting and that does not work. I found another post on this forum from you and followed it. The ASM service was fine the entire time through all the logs and I don't know how to verify LMON in Windows but I didn't see any LMON errors in the alert log. Also, the voting disks are online. Each node has their own and they are mirrored. Where else to look?

We have 2 servers running Oracle 11gR2 Window server 2008 64 bit RAC. Today I add new shared disk visible from both servers. All our data placed on ASM partitions, but we need Windows volume for exchanging some data between servers & users;Actions:then i have prepare disk on shared storage from 1st node, run diskmfmt.msc & rescan disks when windows recognizes new hdd, initialize it.create an Extended partition & Logical drive & Assign drive letter. from another nodes, make sure no drive letter is assigned.
Sometimes Windows automatically assign drive letter. If drive letter is assigned, right click & Change drive letter & Remove. from 1st node, format this logical drive using ocfsFormat.exe after execute below scripts i have face some issues
E:app11.2.0gridcfs>ocfsformat /m P: /c 1024 /v DATA /f /d /aReg Get Cluster Name(): Reg Query ValueEx for CFS_CLUSTER_NAME failed with error 203
This indicates that the Cluster Name has not been configured on this node for OCFSThe volume formatted in this condition will be seen by all nodes running OCFS.

I have a single node Oracle E-Biz 12.1.3 Installation.We plan to convert this to a dual node RAC install and I wanted to run by the steps to perform this AND clone over the current production system to the new RAC system (note this will not be using ASM - but will be based on NetApp NFS)
1. Install GRID 11.2.0.3
- installed acorss two nodes, Binaries can be shared
- voting disks / cluster rigistry MUST be shared
2. Install Database Software for RAC
- Binaries cannot be shared and must be installed on each node independently
3. Configure the GRID for database (database / listeners)
4. Clone over the stand alone system (clone database as RAC)
I will be using SCAN - and therefore would expect all the web services / concurrent manager nodes to point to the SCAN hostname as opposed to individual host names.

When I added a new node to RAC (existng 2 windows server 2008 R2 nodes), using the command,
CODEaddNode -silent
"CLUSTER_NEW_NODES={node3}" "CLUSTER_NEW_PRIVATE_NODE_NAMES={node3}"
"CLUSTER_NEW_VIRTUAL_HOSTNAMES={node3-vip}"
the output was "The cluster node addition <path> was successful".
But when I tried the following command,
CODEcluvfy stage -post nodeadd -node3
I got an error stating
QUOTE "ERROR: Shared resources check for node addition failed
The following node is not in cluster: node3
Post-check for node addition was unsuccessful on all the nodes."
When I checked the inventory logs, I found the following entry
QUOTE SEVERE:

I am using newstart cluster software. currently I have two blade servers in my system and I have configured cluster as well. right now I have one issue. I am using the ip address of 10.34.14.0/28 network for cluster but this can not be accessed from all network so I want to use different range of IP of 10.68.1.0/28 network in the same blade servers. Can I configure two different floating (cluster) IP? the first IP range is for signalling and second IP range 10.68.1.0/28 network is for OMM. I need to use both IP in two blade servers.

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?

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 a 2 RAC node cluster . The problem is that the second listener is not registering any connections . I have verified the services of listener using lsnrctl status (the default name is LISTENER), i also have verified the local and remote listener parameters they are fine but running the fol query shows count =0 against inst_id=2;
SQL > select count() from gv$session where username='XYZ' and inst_id=2;*

I'm a long time Oracle DBA but have only recently started with RAC and have never done any patching or upgrades in a RAC environment.
My environment consists of a 2 node RAC cluster, and 2 physical standbys at separate remote locations.
The database, GI, ASM, and clusterware are all at version 11.2.0.1.
I want to upgrade all components to the latest patchset which is 11.2.0.3. Eventually I also want to apply the latest PSU.
Can I do this without down time? It is a mission critical database where downtime could conceivably endanger lives. If it can't be done with zero downtime, then downtime must be kept to an absolute minimum (minutes, not hours).
I suspect the clusterware needs to be patched first and I do not know whether I can do it on one node at a time.

I am trying to design a database consolidation high-availability cluster for Oracle 11g R2 64-bit Enterprise Edition (X86-64) on Oracle Linux 6.x UEK, using Oracle 11.2.0.3 (the latest as of Aug 2012).
We don't need RAC Multi-Node now or in foreseeable future because none of the databases we run break the capacity of a single node. Likewise, we don't need to use Oracle VM to virtualise the database instances.
We plan to use SGA and PGA memory management to run multiple instances on same hardware operating on a single Linux 64-bit O/S image.Does it sound ok so far?
Two or three of 4-socket, 40-core Intel 64-bit servers with 512GB of RAM each (relatively cheap at today's HW commodity prices) will be sufficient to run all Oracle databases we have on Linux 64-bit.So the two HA options that I know of are:
(1) use Oracle Clusterware/Grid/ASM to provide for instance failover
(2) use Oracle RAC One Node on top of Clusterware/Grid/ASM
As I understand it RAC One Node is significantly more expensive than the "free" Oracle Clusterware/ASM/Grid (since we own Oracle 11.2.0.3 Enterprise Licences already). So why should my employer pay for RAC One Node licence given they already own Single Instance Fail-Over and Restart protection from Clusterware/Grid/ASM ?
I also read that Data Guard 11.2 may not be supported with RAC One Node on 11.2? True? Will same Data Guard 11.2 work with a Single-Instance Failover running on Clusterware/Grid/ASM ?
-Who is running RAC One Node? Why?
-Who is running Single Instance Failover with Clusterware? Why?
-Who is using Data Guard with either of the above?

im having problems with CRS in a Rac installation. Because of this i cant start the database.I installed Oracle Rac 11.2.0.1 with ASM in a Red Hat 5.8 linux server. Everything was ok until a server reboot. I have 2 nodes, nodo1 and nodo2. Both got rebooted and after that im not able to start the cluster.
All the other resources seem to be just fine .
At nodo1:
[root@nodo1 oracle]# crsctl start cluster -all
CRS-2672: Attempting to start 'ora.cssdmonitor' on 'nodo1'

I have been asked to look at making an existing Oracle server resilant. The technology I need to use are:
- Windows 2008 R2 Enterprise SP2
- Microsoft Cluster Services
- Oracle Enterprise 11g release 2
- Oracle Fail-Safe (latest version available)
Unfortunately ApEX 4.1 and Mod_plsql are install on the existing stand-alone server. I'm afraid i know very little about Oracle and ApEX but i need to make a design decision and check fiesablilty.
I believe the HTTP service and Mod_plsql can be moved to a independant server which should work but ApEX itself must remian on the database server (i'm told).Will ApEX work in a MSCS setup? I can only find references to RAC support, RAC is out of scope.

I have a RAC working with SAN raw devices presented to ASM and working fine. My situation has changed since the installation of the RAC. Now I need a shared storage (with a filesystem) to upload some files (so DB can read these as external tables) for this I have used OCFS2.
As you can see I have Oracle RAC on raw ASM + shared storage on OCFS2 and for the time been all seems to be well and working perfectly. Can these coexist with out effecting the other?

I would like to build a 2-node cluster without RAC. I desire to operate 2 Oracle database instances for use by 2 separate applications. I plan to run Linux. I would like node1 to act as the primary server for the databases in application1 and node2 to act as the failover server for the databases in application1. Conversely, I want node2 to act as the primary server for databases in application2 and node1 to act as the failover server for databases in application2. Can Oracle SE and Oracle Clusterware be configured in this this way?
