We have 3 node RAC. In one of the node clusterware is down and also CSSD process is down. I got to know that we have to clear socket files in that node.what needs to be done instead ofclearing socket files.

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' CRS-2672: Attempting to start 'ora.cssdmonitor' on 'nodo2' CRS-2676: Start of 'ora.cssdmonitor' on 'nodo1' succeeded CRS-2672: Attempting to start 'ora.cssd' on 'nodo1' CRS-2672: Attempting to start 'ora.diskmon' on 'nodo1' CRS-2676: Start of 'ora.cssdmonitor' on 'nodo2' succeeded CRS-2672: Attempting to start 'ora.cssd' on 'nodo2'
Recently when we rebooted our RAC system we observed that the cluster crs was not able to start. when we try to issue crs_stat -t we got the above error.
# crs_stat -t CRS-0184: Cannot communicate with the CRS daemon. CRS-1006:The OCR location /dev/raw/raw2 is inaccessible.

I have installed Oracle 10g RAC crs and asm on CentOS release 5.4. When I am rebooting the nodes and starting crs manually All the services on both nodes starting successfully.
Restarting oracle services through services.msc is faster then manual (In command prompt).
Even If we have heavy transaction on the oracle database But we can restart the database within minutes by using services.msc But It will take more time in command prompt(sql>shu immediate). So shall we assume here that services.msc is using shut abort command while restarting the database?
I am trying to install oracle 10g RAC on CentOS release 5.4 (Final), But when I am not able to configure SSH between oracle users on both node.

I am configuring RAC with two nodes. I have mapped iscsi targets successfully. I am unable to mount the ocfs2 filesystem.
mount -t ocfs2 -o datavolume,nointr -L "oracrsfiles" /u02
When execute the above command, it displays the follwing error:
ocfs2_hb_ctl: Device name specified was not found while reading uuid mount.ocfs2: Error when attempting to run /sbin/ocfs2_hb_ctl: "Operation not permitted"
when i'm creating ASM instance, i'm getting an error
Quote:ora-29701: unable to connect to cluster manager
for this there were some workaround given to start css.
i tried everything from /etc/init.d/init.cssd start/enable but nothing worked, then i tried with executing
localconfig delete localconfig add====>it failed and recommended to go for reset option
when i executed localconfig reset i get this following error:
Quote: [root@rac2 bin]# sh localconfig add Successfully accumulated necessary OCR keys. Creating OCR keys for user 'root', privgrp 'root'.. Operation successful. Configuration for local CSS has been initialized
I tried to run the duplicate script after transferring new rman backup to standby. Even after transferring the backup, duplicate command and was unable to open the database.
I am installing 4 Node Oracle RAC 11.2.0.2 on RHEL 5.5 (x86_64) {for the first time} I am having some issues with ASM monitoring from em console. the +ASM instance appears to be "down" on the em console. However i can connect to separate ASM instances on respective nodes and thus know that they are not down. I am trying to find out the reason why em console is not able to communicate with my ASM instance.
DATAPOINT1 --------------- Under Metric Collection Error link, I can see the following error message for all the nodes.
Target: xxxxx Type: Host Metric: Storage Data Collection Timestamp: MON D,YYYY H:MM:SS PM Error Type: Collection Problem Messsage: executable nmhs should have root suid enabled [code]....
Now the problem is that I cannot find any binary named "nmhs" anywhere in the grid installation, but this file exists in oracle database bin directory: -rws--x--- 1 root oracle 67778 May 2 18:04 nmhs
I am also not sure whether this is the error which tells me about the problem why em console is not able to communicate with ASM.
DATAPOINT2 --------------- I tried to run emctl to check if the agent for the ASM instance is running: I set the following for running from grid home: ORACLE_HOME=/apps/RAC/grid ORACLE_SID=+ASM1 [code]....
I have seen in all the forums, that there is a directory named "agent11g". I cant find this anywhere in my installation. Its not there in the grid infrastructure directory or the oracle database directory. what are its contents?, do i need this for my RAC setup?, how to I create this now?
I have 10g 2 node cluster running on Linux OS (redhat 4). Oracle version is 10.2.0.5.0. The problem is when the CRS get start all the services are online but when i try to connect DB, its connecting to idle instance. When I check the details the backgroundprocesses all get started but instance not started. Later i stopped the background processes and start the instance manually using sqlplus, the DB instance started and I can connect. But when i check the crs service status (crs_stat -t), the instance and service status are offline, nodeapps services are online. When i try to restart (crs_start) it throws up error.
I have a 2 node RAC database. I have a service defined as a preferred service for one node and Available for the other node. the service was relocated to the available node. I want to know when it failed over and why. Where would I get this information?
some time After the service failed over to the other node I got connection issues for this service. I relocated the service and the issues went away. Why did it not relocate the service back to the preferred node when these issues were encountered?
We have a new requirement for a RAC environment. Its workload will comprise both OLTP and batch loads. Am I right in thinking that I can map the appropriate applications to the required node using services, e.g.
Application 1 (OLTP) has node 1 as its preferred service node - so all OLTP trxs run through node 1 Application 2 (Batch) has node 2 as its preferred service node - so all batch trxs run through node 2
Both applications will have the other node for its available service to facilitate HA in an emergency.
Does that sound right? (or have I got it completely wrong!)
There are 4 nodes in a RAC environment A,B,C,D..For instance i want to disable all the services for node D temporarily and hand over the Node D to the system admin guys and after the maintainance is done I want to restart the services again on node D..
I have to create a spool file using pl/sql (Oracle 10g/Solaris environment) and then copy the file from solaris environment to sharepoint(windows machine) folder. How to implement this(copy to sharepoint ) in pl/sql.
on 6th of August at 02:36 our following cluster services were down,i see the logs and found that ASM is down and disk group are not accessible and ASMb process is terminated and both instances was restarted, i checked the cluster services so five services were down and these are
Quote: ora_ OCR_DG.DG, ora_fedb96.asm2.asm, ora_fedb96.gsd, ora_fedb96.ons and ora_fedb96.oc4j...
I restarted the services and they were successfully up and application become available . What can be the reason of the service failure?
