To Query The Cluster Name From Server
Dec 20, 2012
We have few Solaris RAC Clusters. When I try to query the cluster name from server using the following command i get the same result for all the clusters.
soc02n02-oracle> cemutlo -n -w
ORA_CRS_01
2:1:
soc03n01-oracle> cemutlo -n -w
ORA_CRS_01
2:1:
While in the OEM Grid Console it shows the separate name given to each of them. Check the attached .pdf
Q.Why the cluster names are same from the OS level but different in the OEM console.
Q.Is there any way we can find out the individual cluster names other than cemutlo commands.
Q.In OEM why is the "Cluster" different from the "Cluster name"

I have installed Oracle Grid on a standalone server and setup Oracle db 11.2.0.2 on Oracle Linux 6.2 64 bit server.When I reoot the server and run crs_stat -t,several daemons havent started thus the ASM and db instances are also down as below
Name Type Target State Host
------------------------------------------------------------
ora.DATA.dg ora....up.type OFFLINE OFFLINE
ora.FRADG.dg ora....up.type OFFLINE OFFLINE

ora.diskmon ora....on.type ONLINE OFFLINE
ora.evmd ora.evm.type ONLINE ONLINE amldb01dc
ora.ons ora.ons.type OFFLINE OFFLINE
I am forced to manually start the daemons via command crsctl start resource -all then I manually start the ASM and db instances. Yet when I run the commands
crsctl config has
CRS-4622: Oracle High Availability Services autostart is enabled.
crsctl check has
CRS-4638: Oracle High Availability Services is online.
Thus I would assume the daemons would start automatically during boot.

What I wanted to know was the steps to place a RAC cluster onto a brand new Linux server.
Step 1 - Install Cluster Software , CRS & Voting Disks
Step 2 - VIPCA - VIP Config (VIP, GSD, ONS) Resouce Apps
Step 3 - Create ASM Instance
Step 4 - Install Grid Infrastructure
Step 5 - Install RAC
Step 6 - Create Cluster DB - using DBCA with Enterprise Manager
This will be a 2 node RAC cluster going onto a Redhat 5 Linux box

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 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 wanted to make my11g cluster down along with high availability.Documents says, Stop the cluster stack by using crsctl stop cluster and then execute crsctl stop crs command to stop HA. What is the difference if I am using the following commands?
1. crsctl stop cluster
crsctl stop crs
OR
2. crsctl stop crs
As per my understanding, crsctl stop crs command stops entire cluster stach plus has.

A basic select and group by query I am optimising for my Database course has returned results that indicate it will perform better on a clustered index when returning a smaller number of rows (5% of the largest table) and on a hash clustered index when returning higher volumes (50% and 80%). I understand that it is possible to use more than one index type on a table to improve performance, but I am struggling to understand how I might establish a hash cluster and a cluster on the same table? and then use hints to drive the query down one access path or the other.

I had installed grid infrastructure for a cluster, and RAC database. The ASM is the storage option. The configurations as follows:
Grid Home: /u01/grid/app
Oracle RAC Home: /oracle/db1/app/product/11.2/dbhome1
Can I have another RAC Database to use the existing Grid infrastructure ? The second RAC database will have different owner than db1.
The configurations as follows:
Grid Home: /u01/grid/app
DB1 Oracle RAC Home: /oracle/db1/app/product/11.2/dbhome1 and Database Name: RACDBA so the current instances are RACDBA1 and RACDBA2
DB2 Oracle RAC Home: /oracle/db2/app/product/11.2/dbhome2 and database name: RACDBB so the future instances will be RACDBB1 and RACDBB2

I have one table called posh, which has about 50,000 ids (millions of rows) so far. It is currently at about 50 gb. So each series of rows for a particular id is about 1 mb.
CREATE CLUSTER posh_cluster (id int)
SIZE 2M
STORAGE (initial 2000K next 2000K)
PARALLEL 4;
CREATE INDEX posh_cluster_index ON CLUSTER posh_cluster;
[code].......
According to the Oracle documentation size is "the average cluster key size", I am not really sure what that means. Is this the 1mb in posh table space I am using for each series of rows for an id, or the space used for the index? Secondly, the storage parameter for 'CREATE CLUSTER' should be what?

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'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 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?

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 had a massive jump in cluster waits specifically; gc buffer busy acquire during an RMAN backup. We identified the cause of the waits to a few hot blocks with a table that may well need re-building in terms of ITLs and PCTFREE (Although I thorght ASSM would manage PCTFREE and PCTUSED..)
What happens during an RMAN backup that may cause huge cluster waits on hot tables? Is there some crazy redo issue going on or maybe flashback?
Either way the spike is there and we can pinpoint the activity on the database but just dont understand why RMAN would cause the issue.We have just found that the LARGE_POOL has not been set, in fact there is no SGA_TARGET either! Could this have an effect on RMAN and cluster waits?

Yesterday I was installing 11.2.0.2 patch to our Oracle 11gR2(11.2.0.1.0) Two node RAC cluster on OEL 5.4 x86 Linux.Before installing I have read [URL] support note which says "Note: All Oracle Grid Infrastructure patch set upgrades must be out-of-place upgrades, in which you install the patch set into a new Grid home. In-place patch set upgrades are not supported. "
During Installation I found following Installation Option :
1) Install and configure Oracle grid Infrastructure for a cluster
2) Configure Oracle Grid Infrastructure for a Standalone Server
3) Upgrade Oracle Grid Infrastructure or Oracle Automatic Storage Management
4) Install Oracle Grid Infrastructure Software Only
Which option should I have to choose here ?
