Log in as the "oracle" user and perform the following tasks on each node. To enable SSH user equivalency on the cluster member nodes issue the following commands on each node. Before installing the clusterware, check the prerequisites have been met using the "runcluvfy.
It's a good idea to take a snapshot of the virtual machines, so you can repeat the following stages if you run into any problems. To do this, shutdown both virtual machines and issue the following commands. Wait while the prerequisite checks are done. If you have any failures correct them and retry the tests before clicking the "Next" button. You can choose to ignore the warnings from the prerequisite checks and click the "Next" button. If you do, you will also need to ignore the subsequent warning message by clicking the "Yes" button.
Click the "Add" button to continue. The "Specific Network Interface Usage" screen defines how each network interface will be used. Highlight the "eth0" interface and click the "Edit" button. To have greater redundancy we would need to define another shared disk for an alternate location. Once the install is complete, run the orainstRoot. The output of the root. The following text is the output from the RAC1 node. Ignore the directory ownership warnings.
We should really use a separate directory structure for the clusterware so it can be owned by the root user, but it has little effect on the finished results. Here you can see that some of the configuration steps are omitted as they were done by the first node. This is because my public IP addresses are actually within the " Enter the vitual IP alias and address for each node.
Once you enter the first alias, the remaining values should default automatically. Click the "Next" button to continue. Select the "External" redundancy option no mirroring , select all three raw disks raw3, raw4 and raw5 , then click the "Next" button. Execute the "root. Enter the values "RAC. Accept the management options by clicking the "Next" button. If you are attempting the installation on a server with limited memory, you may prefer not to configure Enterprise Manager at this time.
If you are attempting the installation on a server with limited memory, you may prefer not to install the JVM at this time. Select the "Custom" memory management option and accept the default settings by clicking the "Next" button. Once the database creation is complete you are presented with the following screen. Make a note of the information on the screen and click the "Exit" button.
This configuration allows direct connections to specific instance, or using a load balanced connection to the main service. There are several ways to check the status of the RAC. Database: Oracle Database 10g R2. I got to create a DR server and ftp archlog files to the DR machine regularly. The Current oracle user frequently breaks the FTP connection.
I thought this would be nice idea to create another oracle account on DR machine and use this to FTP logfile from live. Are you using Dataguard or just are you sending the logs and applying the manually? If you are sending logs using ftp and applying them manually, you can create a shell script to ftp the files across and then later matching the checksum, if the checksum fails then reinitiate the ftp of that file.

We assign IP address for each node to serve as the private Interconnect. Important: Must be separate from the public network Must be accessible on the same network interface on each node Must have a unique address on each node One Network Ethernet Card for public connection.
Any existing ASM instance on any node in the cluster is shut down. If you do not have a storage option that provides external file redundancy, then you must configure at least three voting disk areas to provide voting disk redundancy. Note: This step is intended for educational purposes only. Step 5: Check Patches Refer to your operating system or software documentation for information about installing packages Step 6: Check Kernels parameter We Will discuss Separately Step 7: Configuring the Network Requirements Follow these steps on each node: If necessary, install the network adapters for the public and private networks and configure them with either public or private IP addresses.
Step 1 Start run installer. Please use bellow command. Step 6 Specify network interface usage. At least one interface should be public. You may like these posts. This is an excellent article.
