Table of Contents

Configuring Multiple SAP HANA Instances

If your configuration has multiple database instances that are associated with the same host, you must manually create a link to the corresponding SID user's BACKINT interface before you create the pseudo-client.

  • On the command line, type the following:

ln -s /opt/commvault/iDataAgent/backint /usr/sap/<SID>/SYS/global/hdb/opt/hdbbackint

Creating the SAP HANA Parameter File

You must configure the SAP HANA parameter file so that the SAP HANA BACKINT interface can work with the Commvault software. For information on how to configure the file, see Creating the SAP HANA Parameter File.

Creating the Media Parameter File

Command line backups use the storage policy and the data path specified in the CommCell Console SAP HANA database instance by default. You can specify these parameters in a file. For information on how to create the file, see Specifying the Media Parameters for SAP HANA Command Line Operations.

Creating a Pseudo-Client

Create a pseudo-client and configure an instance to facilitate backups. Each instance references a HANA database.

Note: You must add all of the instance nodes to the pseudo-client so that you have data protection.

Before You Begin

  1. Decide how to connect to the database. If you want to use the SAP HANA user store, create a key.

    For information, go to the SAP website, hdbuserstore.

  2. Determine the location of the SAP HANA hdbsql tools.
    1. Log in to the SAP HANA server with the sid admin credentials.
    2. On the command line, type the following command to find the location.

      which hdbsql

      Use the location that the software returns in the hdbsql location directory box.

Procedure

  1. From the CommCell Browser, right-click the Client Computers, point to New Client > Application, and then click SAP HANA.

    • In the hdbsql location directory, enter directory that contains the SAP HANA hdbsql tools.
  3. On the Details tab, add the SAP HANA instances to the pseudo-client . You must add all of the instance nodes.

    The Primary Name Server must be the first one that you add in a multi-node coniguration.

    1. Click Add.

      The Create SAP Hana client dialog box appears.

    2. From the Hana physical client Name list, select the clients that hosts the SAP HANA instance.
