Adding A New Node In Oracle RAC

Aug 8, 2011

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:

oracle.sysman.oii.oiix.OiixException: The Oracle home '<path>' could not be updated as it does not exist.
at oracle.sysman.oii.oiic.OiicBaseInventoryApp.getOracleHomeInfo(OiicBaseInventoryApp.java:645)

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

Adding New Node Back To Cluster Via Documentation

Apr 10, 2012

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?

Data Guard :: How To Find Apply Node In RAC Two Node Standby DB

Aug 16, 2013

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?

RAC & Failsafe :: Single Node RAC - Configure Only One Server Instead Of Two Node?

Sep 13, 2012

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).

RAC/ASM Clusterware Installation :: Adding New OCFS Disk To Oracle Cluster On Windows

Oct 17, 2013

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.

RAC & Failsafe :: Configure Oracle Dataguard For 2 Node Database

Oct 28, 2010

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.

SQL & PL/SQL :: Adding High And Low To Zip Plus Four Values?

Jan 19, 2011

I have a table with zip codes and their plus four values. For ex: zip code of 10000, which has corresponding plus four values of 001, 002, 003, and 008, 009, 010. The issue is just that--a zip code can have sequential plus four values, and then it will skip several potential plus four values, and then start again. I would like to assign a low plus 4 value and high plus four value to a zip code, keeping in mind that the plus four values are not always sequential. So, it would be similar to this:

zip plus4 low plus4 high
10000 001 003
10000 008 010
