Chapter 15 - RAC Migration Topics

Perform the Pre-Installation Steps

Next, perform the pre-installation steps as documented in "Software Installation, Database Creation and Configuration" (chapter 6 of this book). For example, on UNIX-based systems, this includes creating the oracle user account and the dba group on all nodes, setting up oracle user equivalence (rsh and rlogin using rhost and hosts.equiv files), set the DBCA_RAW_CONFIG environment variable, if raw files are used, and so on. Then set up shared storage by referring to the "Preparing Shared Storage" section in chapter 5.

You should use your vendor manuals to setup the shared disk array, RAID, and other shared disk requirements.

Setting up the Cluster

If you are using vendor supplied clusterware, use your vendor's documentation to form a cluster with the required number of nodes. Once you have configured all of the nodes in your cluster, either with or without vendor clusterware, you must install CRS by referring to the procedures in "Software Installation, Database Creation and Configuration", chapter 6 depending on your operating system.

Move the Preconfigured Database Image to the Install Target

This involves copying the database structure file and the database preconfigured image file that you created with the DBCA in the previous section, to a holding location on the node in the cluster from which you plan to run the DBCA to create the RAC database physical files.

Install the Oracle Database 10g RAC Software

1. Run the Oracle Universal Installer (OUI) to perform an Oracle installation for the Oracle 10g Database software with RAC. Note that if the CRS has not been installed, the RAC option will not be available
    

2. Select Cluster Installation Mode on the Specify Hardware Cluster Installation page of the Oracle Universal Installer (OUI) and select the nodes to utilize for your RAC database.
    

3. On the OUI Database Configuration Types page, select Advanced install.

After installation of the Oracle software, the OUI automatically runs the post installation configuration tools such as the Network Configuration Assistant (NetCA) and the DBCA.

4. From the DBCA Template Selection screen, select the template that was copied to the temporary location in the previous section. Utilize the browse option to select the temporary location where the template files are located.
