Preinstallation Checklist for the Oracle Agent on UNIX

The Oracle Agent backs up and restores Oracle databases in your enterprise. You can also configure the agent to incorporate archiving and snapshot management solutions. For more information, see the Oracle Backup Administrator Guide.

Use this preinstallation checklist to prepare the computer where the Oracle Agent will be installed and to gather all of the information you will need during the installation.

Determine the Installation Location

Based on your environment, install the Oracle Agent on an appropriate computer.

Environment

Where to install the software

Non-Clustered

On the computer on which the Oracle server resides.

For Oracle Solaris computers, install the Oracle Agent on one of the following setups:

  • The computer hosting the global zone on which the Oracle server resides.
  • A computer in a non-global zone on which the Oracle server resides.

Clustered

On the physical nodes of the cluster where the Oracle server resides.

If you want to protect the Oracle Real Application Clusters (RAC), install the Oracle Agent on all the nodes of the Oracle RAC.

Cluster installations are not supported on FreeBSD and Macintosh computers.

Verify System Requirements

Verify that the computer where you plan to install the Oracle Agent satisfies the minimum requirements. For more information, see System Requirements.

Verify License Requirements

Based on the licensing mechanism used in your CommCell environment, verify that the CommCell has the required licenses to use the Oracle Agent. For more information, see License Requirements.

Gather Installation Data

Refer to the items in this section to gather the information that you will need during the installation. Record the information before you begin installing the software, so you can refer to it during the installation.

You can install the Oracle Agent using either the CommCell Console or the installation package created by the Download Manager. Any item that applies to only one of these installation methods is noted.

Commvault package to install

  • For installations using the CommCell Console, install the Oracle package, which is listed under the Database category.
  • For installations using the installation package, install the Oracle package.

Note: If the File System Agent is not installed on the computer, the File System Core and File System packages are automatically installed with the package you selected. The File System Agent will not consume a license.
For more information on the package options and to gather the required information for the File System Agent, refer to the Gather Installation Data section in the Preinstallation Checklist for the UNIX, Linux, and Macintosh File System Agent.

Client computer details

If the File System Agent or another package is already installed on the computer, you are not required to gather all the computer details again. The level of detail depends on how the package you selected is installed, as follows:

  • For installations using the CommCell Console, the installation program requests only the name of the client computer.
  • For installations using the installation package, the installation program reads the details from the previous installation.

UNIX Group and access permissions

If you did not assign a UNIX group during the installation of the File System agent, make sure to do the following during the installation:

  • Assign the UNIX group that is used by the database application
  • Include the database users into the group

You will be able to set the access permissions for the group. By default, read/write/execute permissions are granted to the UNIX group.

Auto Discovering Oracle Instances

By default, the Commvault software creates CommCell instances for Oracle databases under the following conditions:

  • Discovery is initiated every 24 hours.
  • When the Communications Service (GxCVD) is restarted (for example after a computer reboot).
  • Instances that are defined in the Oracle oratab file, which is created by Oracle at installation and acts as a database registry file. On Solaris systems, this file is normally located in the /var/opt/oracle directory and on Linux/UNIX systems, it is located in the /etc directory.
  • Instances that are in the NOMOUNT, MOUNT or OPEN state. The software does not discover instances that are shut down.

If you do not want the software to discover the databases, then you can set the nDisableAutoDiscoverInstancePostInstall additional setting on the CommServe computer and set the value to 1 before you install the Oracle Agent on your clients. When you set the additional setting to 1, the software makes the auto discovery feature unavailable on any client that you install the Oracle Agent software.
