This section explains how to install and deinstall DA-RMAN.

DA-RMAN is an add-on module for backup3G, and is installed through the COSmanager configuration menu.

You will need:

a distribution containing the DA-RMAN module
COSmanager 4.2.5 (or newer) and backup3G 3.2.6 (or newer) must already be installed and licensed on each target host
the name of the Oracle user
the RMAN connect strings and Media Catalog (if used) connect strings
the location of the ORACLE_HOME directory
you must be a COSmanager user with the Manager or Config role.

The installation procedure copies the DA-RMAN files to a target directory you specify, then adds the module to the COSmanager application table.

See Installing COSmanager Applications in the COSmanager User Guide for full details of how to install COSmanager add-on modules.

The DA-Oracle software must be installed on the backup3G master host, and every host that has Oracle 9i/10g databases that you wish to back up.

If you will be installing from a file, copy the cpio archive to the /tmp directory on the local host.

Launch COSmanager, then select Config from the COSmanager button bar.
From the Product configuration menu, select COSmanager configuration > COSmanager applications.
Select Application > Install.
Enter the full path to the file name to install from, or choose from the pull-down list of files.
Press Accept.
DA-RMAN must be installed under an existing copy of backup3G. If more than one version of backup3G is installed you must choose which version to use.

The install procedure now:

adds an entry for DA-RMAN 1.1 to the COSmanager applications table
copies the DA-RMAN files from the distribution file to the target directory
updates the backup method, recovery method and backup format tables with new entries.

This completes the installation phase. The next step is to configure the Oracle Instances you wish to backup.

DA-RMAN needs to know the name of the Oracle user, and/or the connect string, the values of $ORACLE_HOME and $ORACLE_BASE on each host.

Configuring DA-RMAN only needs to be performed on the backup3G master host.

Launch COSmanager, then select Config from the COSmanager button bar.
From the Product configuration menu, select backup3G configuration > Maintain backup jobs.
Select Databases > Oracle instances.
Select Instance > Add.
Fill in the following fields:
SID
The Oracle instance name to backup.
Database host
The host that the instance lives on.
Home
Enter the value of the $ORACLE_HOME. DA-Oracle uses this to find certain files of each SID to back up.
Base
Enter the value of the $ORACLE_BASE. DA-Oracle uses this to find certain files of each SID to back up.
OS user
Choose the user account that owns the Oracle files on this host.
Connect string
The instance connect string in the format /, <user>/<password> or <user>/<password>@<service>.
Catalog string
If a separate media catalog database is used, then enter the catalog connect string in the format /, <user>/<password> or <user>/<password>@<service>.
Test connection(s)
This will check that the SID is running. If so, then check that it can connect to the SID, and if used, check it can connect to the catalog database as well. Finally, it checks that the SID has archive log mode switched on.
Press Accept.
Perform the steps above for each Oracle Instance you plan to backup using backup3G.

From the COSmanager configuration menu, select COSmanager applications.
Select DA-RMAN.
Select Application > Deinstall.
Press Accept to remove the software from disk and to remove the backup and recovery methods and other table entries inserted during installation, and its entry in the application table. Press Exit to leave the application as is.

 #;Test connection(s): This will check that the SID is running.  If so, then check that it can connect to the SID, and if used, check it can connect to the catalog database as well.  Finally, it checks that the SID has ''archive log mode'' switched on.
 #Press Accept.
+#Perform the steps above for each Oracle Instance you plan to backup using [[backup3G]].
