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?

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'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:

Normally if node fails, VIP & resources are transferred to another node (clients need to failover).
if node is back again CRS detect this, make it as 'family member' and try transfer VIP & resources back to this node (clients will force to failover again).
this failover (despite of failover method I use) make each uncommitted transaction to be rolled back. client need to be disconnected from the service and VIP through they are connected to this service and they need reconnect to the new node - during this stage all DMLs modifications are gone, and need to be re execute.

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:

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 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 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 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).

A coworker of mine asked if there was any documentation from Oracle that listed all of the parts of the AWR report and what each meant. I was taken back because I don't think there is. There are third party books that talk about AWR reports and their predecessor Statspack reports.
Oracle has some notes on their support site about reading an AWR or Statspack report. All I found in the official documentation was some basic information about how to run an AWR report and an overview of what it was. It would be nice to have some sort of documentation that lists out each section and explains the units and purpose.

I am having setup of 2 node 10.2.0.4.0 RAC setup on ASM with Single Instance Physical standby on File System (OS: RHEL 5.4). I configured DG Broker without any major issues. Getting all output of 'show configuration' and all DG related logs are clear. Archives are getting transferred from both Primary nodes.
DGMGRL> show configuration
Configuration
Name: dg_rac
Enabled: YES
Protection Mode: MaxPerformance
Fast-Start Failover: DISABLED
Databases:
livestdby - Primary database
livedg - Physical standby database
Current status for "dg_rac":
SUCCESS
Now I am getting error Error: ORA-16535: CRS is preventing execution of a broker operation.
DGMGRL> switchover to livedg;
Performing switchover NOW, please wait...
Error: ORA-16535: CRS is preventing execution of a broker operation
Oracle Says
Quote:Cause
A broker operation was underway that required CRS to stop managing the instances of this database, but CRS management could not be stopped on behalf of the broker"s request on at least some of the instances, so the broker operation was canceled.Suspend CRS management of this database using SRVCTL STOP DATABASE -D <name> -O NONE. Then reissue the broker request.But this command is not working as it's given to stop the database.
One more thing, it's nowhere said to stop CRS while performing Switchover / Switchback using DG Broker. When we do Switchover / Switchback we keep open only one of the Primary instance.
is there any documentation / link available to switchover of RAC database using dgmgrl (DG Broker)

I converted the access db's to access 2003, the version I am running. Still, after fighting with this for a couple of days I can't get this to work and can't find information on what's wrong. I keep getting:
Error #49 - XMLExporter - ActiveX Component Can Not Create Object....Database Schema did not complete successfully.
This is really getting old. If this doesn't work is there a way to copy the tables into SQLDeveloper without the exporter tool? Like I said, I'm really at my end with this.

The requirement is, the combination of col1,col2,col3 and col4 should always be unique, and wherever the col1, col2,col3 are same then col4 should be the sequence, starting from 1. Likewise the data should be updated back to the table.I'm able to do this using PL/SQL. Can I do the same using a single update statement?
create table tab1 (col1 number(5), col2 number(5), col3 number(5), col4 number(5));
Existing Data:
insert into tab1 values (101,521,3,1);
insert into tab1 values (101,521,3,1);
insert into tab1 values (101,522,3,2);
insert into tab1 values (101,522,3,2);
insert into tab1 values (101,523,3,1);
insert into tab1 values (101,523,3,2);

I come from a world of MSSQL and have been thrown into doing some Oracle work. Great! Ok, moving on.. I work in an environment where I do not have direct access to the database tables that I need data from. As a workaround, I have been asked to create a stored procedure that will be loaded into our CRM system's production db once it goes through the internal "approval" process.Basically, I need to return a result set back to the client by calling a stored procedure.
Version 1 of this that was already in place was done with the following code.
procedure events_by_day (p_start_date IN OPERATION_LOG.DT%type,
p_end_date IN OPERATION_LOG.DT%type,
p_results OUT SYS_REFCURSOR) IS
BEGIN
OPEN p_results FOR
[code]....
Then the code is executed from the client side like so:
events_by_day(p_start_date => to_date('2012-3-27 00:00:00', 'YYYY-MM-DD HH24:MI:SS'),
p_end_date => to_date('2012-3-29 23:59:59', 'YYYY-MM-DD HH24:MI:SS'),
p_results => r_cursor);
LOOP
FETCH r_cursor
INTO event_date, event_acct_no, event_type, event_count;
[code]....
As you can see, a SYS_REFCURSOR was used in this case to pass the data back.
