InstallationInstallation steps for Oracle RAC on Windows 2003 Enterprise x64 Edition.

ClusterwareOracle Clusterware Installation

Clusterware Pre-Installation NetworkingEach node in the cluster must have two network interfaces. One interface, called public is used by clients to connect to the cluster. The other interface, called private is used for cluster network traffic only between nodes.

Note, the names of the network interfaces must be exactly the same on each node in the cluster and have the same case.

For the private interfaces we will use the subnet 10.1.1.0, using 10.1.1.180 for rac1 and 10.1.1.182 for rac2.

For the public interfaces we will use the subnet 192.168.1.0 using 192.168.1.180 for rac1 and 192.168.1.182 for rac2.

In addition, Clusterware will assign a "virtual" IP address to each node in the cluster. These IP addresses must not be defined in the Windows Network Settings. Clusterware takes case of the VIP assignment.

For the virtual ips we will use 192.168.1.181 for rac1 and 192.168.1.183 for rac2.

To configure the public interface. right click on the interface and select Properties.

.Select "Internet Protocol (TCP/IP)" and click the Properties button.

Note, change the default gateway and DNS server to appropriate values for your network.

Repeat this process to configure the private interface.

The public interface must also be listed first in the network binding order. This can be done by clicking Advanced Settings from the Advanced menu of the Network Connections window.

If the public interface is not listed first, use the "up arrow" button to move it to the top of the connection list.

Finally, Media Sensing needs to be disabled for networking on the nodes. Media Sensing is a feature used to detect if network interfaces are in a link state. When a link goes down, Windows will unbind protocols from the interface, this can cause problems with Clusterware and must be disable.

Using the Registry Editor (Start->Run "regedit").

Add a new DWORD value in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters called DisableDHCPMediaSense and set it's value to 1.

Clusterware Pre-Installation StorageIn this example, I have defined 3 persistent disks shared between my two guests: 2 x 10GB and a 40GB disk. The intent is to use the 10GB disks for the OCR and Voting disks and the 40GB disk for data and flash partitions.

Using the Disk Management interface in Windows, right click on the 10GB disk and select New Partition.Click Next.

Select Extended partition and click Next.

Use the entire disk for the partition and click Next.

Click Finish to create the partition.

Now, we need to create a new logical disk. Right click on the newly created partition and select New Logical Disk. Click Next.

Select Logical drive and click Next.

Use the entire disk for the partition and click Next.

Select "Do not assign a drive letter or drive path" and click Next.

Select "Do not format this partition" and click Next.

Click Finish to create the partition.

Repeat this process for the second 10GB disk.

For the 40GB, following the steps above, create an extended partition occupying the entire disk, but create 2 logical partitions of 35GB and 5GB.

Each node may need to be restarted before they can see the partitions on the shared disks. After a restart, Windows may assign a drive letter to the partitions. These drive letters should be removed through the Disk Management interface before proceeding.

Right click on the volume and select "Change Driver Letter and Paths...".

Highlight the drive letter and click Remove.Click the Yes button to remove the letter.

Clusterware InstallDownload Oracle Clusterware Release 2 (10.2.0.1.0) from http://download.oracle.com/otn/nt/oracle10g/10201/102010_win64_x64_clust...

Unzip the software to a temporary staging area that will be called $STAGING_DIR from this point onwards.

Included as part of the installation software is the Cluster Verification Utility (CVU). This utility can be used to verify the cluster before and after installation. Before the cluster software has been installed, this utility is available in the $STAGING_DIR\10210_win64_x64_clusterware\clusterware\cluvfy directory.

Execute the following from a command prompt:> runcluvfy.bat stage -pre crsinst -n rac1,rac2 -verbose

The tool should generate the following output:

System requirement passed for 'crs'

Pre-check for cluster services setup was unsuccessful on all the nodes.

Note, the tool will fail with the error "Could not find a suitable set of interfaces for VIPs.". This is normal as we have used a private subnet (10.1.1.0) for the VIP interfaces.

If no other errors have occurred, now run the setup.exe found in $STAGING_DIR\10210_win64_x64_clusterware\clusterware.

Click Next.

Enter the name and path for the cluster home and click Next.

The installer will now run prerequisite checks. Click Next.

Enter a name for the cluster. We also need to add our second node. Click Add and enter in the information for rac2.

Click Next.

The interface type needs to be changed to "Public" for our public interface. Click Edit.

Click Next when done.

Now we need to select partitions that will be used as the Oracle Cluster Registry (OCR) and the Voting disk. Highlight the partition to be used for the OCR disk, click Edit and mark it.

Now, highlight the second partition and mark it as the Voting disk.

Click Next when done.

A warning dialog will pop up recommending that an OCR mirror disk be created for redundancy. Click OK.

A warning dialog will pop up recommending that an Voting mirror disk be created for redundancy. Click OK.

For the purposes of this example, we do not need any redundancy as the install is in a virtual machine. Click Next to continue.

The summary screen should now be displayed.

Click Install to begin the installation.

Once the installation has completed, the configuration assistants will run.

The Virtual Private IP Configuration Assistant will fail for the same reason that the CVU utility failed due to the private subnet being used. Click OK to continue

Another warning dialog will pop up. Click OK to close it.

Click Exit to close the installer.

We now need to the run VIP Configuration Assistant manually since it failed during the install. From the $CLUSTER_HOME\bin directory, run vipca.bat and click Next.

Select the public interface and click Next.

Now enter in the hostnames for the VIP interfaces for each node. If your hosts file or DNS is setup correctly, the IP Address column should fill in automatically. Click Next when done.

A summary screen should now be shown. Click Finish.

The assistant should now run. Click OK when it is finished.

A dialog will now be display showing the configuration results. Click Exit to close the assistant.

Clusterware should now be installed and running on both nodes. To verify the installation, run the CVU utility from $CLUSTER_HOME\bin

Post-check for cluster services setup was successful.

Clusterware Upgrade from 10.2.0.1 to 10.2.0.3Before we install anymore software, the Clusterware install should be upgraded from 10.2.0.1 to 10.2.0.3.

The first thing to do is to download the patch 5337014 from Metalink.

Unzip the patch to a temporary directory on any of the two nodes and run setup.exe and click Next.

Select the Clusterware home and click Next.

Cluster installation should already be selected at this point. Click Next to continue.

The summary screen should be displayed at this point. Click Next to continue.

At this point the patch software will be deployed to all the nodes in the cluster.

The patch software should be now be deployed to each node. Click Exit to close the installer.

At this point, the patch has not been installed. It has only be staged to each node in the cluster. We now need to apply the patch on a rolling basis to each node. NOTE: the following steps need to be repeated for each node in the cluster.

The first thing we need to do is to stop all the Oracle services. From a command prompt, execute the following commands:

> net stop OracleCRService> net stop OracleEVMService> net stop OracleCSService> net stop "Oracle Object Service"> net stop OracleClusterVolumeService

To verify that all Oracle services have stopped, there should be no output from the following command:

> net start | findstr Oracle

It is also a good idea to stop the Microsoft Distributed Transaction Coordinator, as it may have loaded some Oracle libraries that need to be patched.

> net stop MSDTC

Now, go to the $CLUSTER_HOME\install directory and run the patch installer:

> patch102.bat

The command may fail with the following error message:

Failed to patch all the files in the ORA_CRS_HOME C:\oracle\product\10.2.0\crsPlease ensure that all processes running from the home have beenstopped.

If the MSDTC has already been stopped, this is most likely due to two ons.exe processes that are still running. Using the Windows Task Manager to kill these two processes.

Now execute the command again and if successful it should display the following message:

Successful upgrade of this node to Oracle Cluster Ready Services 10203

Automatic Storage Management (ASM)Oracle Automatic Storage Management (ASM) Installation

Automatic Storage Management (ASM) InstallationOracle ASM is a new feature of Oracle 10g used for storage management which is consistent across all server and storage platforms. ASM provides many advantages, including:

adding additional disks requires no downtime I/O distribution filesystem is not buffered allowing for direct I/O kernelized asynchronous I/O

Run the cluster verification cluvfy to verify the cluster is ready for a database installation by executing the following command:

Re-installing Oracle RAC After Failed Installation

I encountered a situation where I needed to re-install an Oracle RAC installation.

The two nodes in my cluster were fresh installs of Win2003 R2 Enterprise x64 Edition. In this case I needed to reuse the shared disk between the two nodes.

Running the cluster verification utility (runcluvfy.bat), my two machines passed cluster pre-install check:

> runcluvfy.bat stage -pre crsinst -n rac1,rac2 -verbose.

The problem happened during the actual install itself during Storage Configuration stage. The two partitions that I had previously selected as my OCR and Voting disks were not listed.

Checking the installer logs (these are normally found in C:\Program Files\Oracle\Inventory\logs and will be called installActionsYYYY-MM-DD_hh-mm-ssAMPM.log), I found the following:

nodeList = rac1,rac2INFO: Query Returned: B:,E:,F:,G:,H:,I:,J:,K:,L:,M:,N:,O:,P:,Q:,R:,S:,T:,U:,V:,W:,X:,Y:,Z:INFO: Setting variable 'sl_Drives' to 'B:,E:,F:,G:,H:,I:,J:,K:,L:,M:,N:,O:,P:,Q:,R:,S:,T:,U:,V:,W:,X:,Y:,Z:'.

The important line the above mess is:

INFO: Query Returned: ocrcfg,1,1,10229,votedsk1,2,1,10229,,3,1,35001,,3,2,5946

Apparently, the Oracle Installer is smart enough to recognize that 2 of my 4 partitions have labels "ocrcfg" and "votedsk1" and is not listing them because as far as it knows, theses partitions are in use by another cluster.

I tried deleting my partitions, re-sizing them, re-formatting with full NTFS and then restarting the Oracle Installer. Once again, the same problem occurred, the disks still had these labels.

It turns out Oracle includes two utilities that are part of the Clusterware install for removal of disk labels and low-level formatting of partitions

guioracleobjmanager.exe logpartformat.exe

The catch here is that you need to retrieve the files from CLUSTER_HOME\bin directory. If you do not have Clusterware installed on another machine, you will not be able to get access to these files and may need to call Oracle support to get copies of them.

In my case, I was able to copy these executables and the appropriate DLLs to my install machines.

Run the guioracleobjmanager.exe tool.

As we can see above, this utility lists any labels that Oracle has applied to the shared storage. We can see the same names we saw in the install log: ocrcfg and votedsk1.

From a command prompt, we now need to format this partitions using the logpartformat.exe utility:

> logpartformat /q \\.\ocrcfg> logpartformat /q \\.\votedsk1

Once both partitions have been formatted, we need to remove the labels from the disks using the Oracle Object Manager.

Check the checkbox on each line with the disk labels that we just formatted and select the Commit menu item from the Options menu.

The partitions should now appear in Oracle Universal Installer during the Clusterware installation.
