Installation prerequisites

Before installing the Plug-in for SAP HANA, verify that the following software is installed and configured:

•
NetVault Backup Server or Client software: At a minimum, the Client version of NetVault Backup software must be installed on the machine hosting the SAP HANA database. For an example of a suitable environment, see Reviewing the recommended configuration.
•
SAP HANA software: This database software must be installed and properly configured on the machine serving as the SAP HANA Server.
•
Client added to the NetVault Backup Server for access: If the machine that hosts the targeted SAP HANA database is not the NetVault Backup Server, this machine must be added to the NetVault Backup Server as a NetVault Backup Client. For more information, see the Quest NetVault Backup Administrator’s Guide.

Reviewing the recommended configuration

While you can set up a single machine as both the NetVault Backup Server and the SAP HANA Server, that is, all software installation and configuration requirements are performed on a single machine, Quest recommends that these two entities exist on separate machines. The following table displays an ideal setup for use with the Plug-in for SAP HANA, including the software and configuration requirements to establish this type of environment.

Installing or upgrading the plug-in

1
Access the NetVault Configuration Wizard or Manage Clients page.
•
To access the NetVault Configuration Wizard page:
a
In the Navigation pane, click Guided Configuration.
b
On the NetVault Configuration Wizard page, click Install Plugins.
c
On the next page, select the applicable clients.
•
To access the Manage Clients page:
a
In the Navigation pane, click Manage Clients.
b
On the Manage Clients page, select the machine that contains the SAP Backint database, and click Manage.
c
On the View Client page, click the Install Plugin button ().
2
Click Choose Plug-in File, navigate to the location of the “.npk” installation file for the plug-in, for example on the installation CD or the directory to which the file was downloaded from the website.
Based on the OS in use, the path for this software may vary on the installation CD.
3
Select the file entitled “hana-x-x-x-x-x.npk,” where xxxxx represents the version number and platform, and click Open.
4
To begin installation, click Next.
After the plug-in is successfully installed, a message is displayed.
 
* 
IMPORTANT: The Plug-in for SAP HANA must exist on the NetVault Backup Server, regardless of the configuration in use. Therefore, if you are using a single machine configuration, installation is complete. If you are using the recommended Client/Server configuration, repeat the installation process, this time installing the plug-in on the NetVault Backup Server.

The plug-in installation file depends the OS in use. The same installation file cannot be used for different operating systems. Therefore, if you are using the recommended configuration and the NetVault Backup Server and SAP HANA Server are each running a different OS, the proper installation files must be obtained and used; that is, from the plug-in installation CD or from the Quest website.

5
Install the license for Plug-in for SAP HANA.
6
After the plug-in is installed, on the NetVault Backup Server, locate and open the “allowdupjobname.cfg” file in a text editor.
This file is located in the config directory of your NetVault Backup installation directory.
7
Locate the [plugins to allow duplicate job name] section, and add SapHana under this section.
8
Save and close the “allowdupjobname.cfg” file.
9
Create a symbolic link for hdbbackint.
To do so:
a
Open a PuTTY session to the SAP HANA Server, and log in using the <SID>adm user.
Do not use the root user to create a symbolic link.
b
Use the change directory — cd — command to go to the /usr/sap/<SID>/SYS/global/hdb/opt directory.
c
Run the following command to create the link:
ln -s <NetVaultBackupInstallDirectory>/bin/hdbbackint hdbbackint
10
Update the backup settings for backups of data, logs, and catalogs to use Backint.
You can use SAP HANA Studio or you can update the “global.ini” file to update these settings. For more information, see your SAP HANA Administration Guide.
11
If you are using a multiple-host SAP HANA environment, install the NetVault Backup Client software and the plug-in software on each additional host.
 
* 
IMPORTANT: Ensure that you use the same path for the NetVault Backup installation directory on each host so that creating a symbolic link from one host works for all other hosts in the environment.
12
Ensure that you use the same path for the NV installation directory on each host so that creating a symbolic link from one host works for all other hosts in the environment.
