Clone GI and RDBMS homes in Oracle RAC 11.2.0.3 with clone.pl

Clone GI and RDBMS homes in Oracle RAC 11.2.0.3 with clone.pl

In this article you will look at how to use clone.pl script to clone GI and RDBMS home of an existing Oracle RAC database installation to add a new node and extend the existing cluster. For additional approaches to add or delete a node to an Oracle RAC click here. The clone.pl can also be used to clone existing GI and RDBMS homes of one cluster to create a new Oracle clusters on another set of servers. You will have a look at how to manually add a RDBMS instance to the new node without using the dbca. The article refers to an existing Oracle cluster consisting of nodes raclinux1 and raclinux2 as described here and later upgraded to 11.2.0.3 as described here.

You will look at the following topics related to extending a node using clone.pl

  1. Clone GI home to the new node
  2. Clone RDBMS home to the new node
  3. Manually add an instance to the new node

Cloning existing home to either extend a cluster to a new node or to create a new cluster has an advantage of considerably reducing deployment time as cloning copies an original source GI and DRBMS home along with all patches and creates an identical image on the target node(s). Apart from distributing all patches from source to target location the cloning mechanism maintains the oracle inventory on the target location resulting in having cloned Oracle GI and RDBMS homes that can be maintained and patched as any standard Oracle home installation using opatch, OUI or OEM.

Adding and Deleting a Node from Oracle RAC 11.2.0.3

In the article you will have a look at the steps related to extending an existing Oracle cluster by adding a node to the cluster and the opposite steps to remove a node from the cluster. Oracle 11.2.0.3 is used for verifying the reconfiguration steps in the article. Two nodes Oracle cluster consisting of nodes (raclinux1, raclinux2) with specifications described here and third node raclinux3 are used as a basis for the reconfiguration test described in the article. GI is installed using non-GNS setup and the database is admin policy managed. You can find information related to the upgrade to 11.2.0.3 here. The article will cover the following topics:

  • Add a node
    • Add GI home to the new node
    • Add RDBMS home to the new node
    • Add instance to the new node
  • Remove a node
    • Remove an instance from the node to be removed
    • Remove RDBMS home from the node to be removed
    • Remove GI home from the node to be removed
