Installing and Configuring the DPX Plugin for SAP HANA

Catalogic DPX can be used to protect SAP HANA databases. The plugin for SAP HANA must be installed and configured on the SAP HANA node.

Before you begin

Once the DPX client has been installed on the SAP HANA node, the installation and configuration script must be run to establish the DPX plugin. Backup and restore operations must be orchestrated through SAP HANA Studio and will use DPX.

About this task

The DPX Master Server software must be installed and configured in your enterprise.

Ensure that the DPX client software is already installed on the SAP HANA node. For more information, see Installing the DPX client for SAP HANA.

The installation and configuration script must be run using the superuser account (root) on the SAP HANA node.

During the installation portion of the script, a link from the SAP run directory is made to a DPX module in the /opt/DPX/bin directory. Additionally, several DPX files have their permissions modified which are listed during the execution of the script. The database’s current backup or restore behavior is not modified.

During the configuration portion of the script, a DPX parameter file (dpxhdb.utl) is created and the SAP configuration file (global.ini) is modified. The configuration step alters the database’s current backup or restore behavior in that subsequent backup or restore (recovery) of the database will utilize DPX plugin.

Before running the installation and configuration script, ensure that you have the following information available from your environment:

  • The hostname or IP of the DPX Master Server.

  • The username of the DPX administrator account (this will most likely be dpxadmin).

  • The password of the DPX administrator account (this will most likely be the password for dpxadmin).

  • The fully qualified path to the DPX root directory.

  • The logical hostname of the SAP HANA node.

  • The name of the DPX media pool that will be used.

  • The name of the DPX device cluster that will be used as a backup target.

  • The name of the DPX device that will be used as a backup target.

  • The System ID (SID) of the SAP HANA database being installed and configured.

Procedure

  1. Using the secure shell protocol (SSH), log in to the SAP HANA node host which is to be interfaced with DPX.

  2. At the command line, navigate to the misc directory: # cd /opt/DPX/misc

  3. Run the installation and configuration script to install the DPX plugin. Issue the following command: # ./dpxhdbinst

    The script may be terminated at any time by entering the word quit.

  4. Enter the DPX Master Server information. When prompted, enter the following:

    • The hostname or IP address of the DPX Master Server.

    • The DPX administrator account username.

    • The DPX administrator account password.

    • The DPX root directory (this will most likely be /opt/DPX/).

  5. Enter the System ID (SID) of the SAP HANA database. This will set the HDBbackint directory to /usr/sap/<xxx>/SYS/global/hdb/opt/, where <xxx> represents the SID of the SAP HANA database to be protected.

  6. Proceed with installation of the DPX plugin, press 1. Installation will create a link and change permissions of three files and one directory as indicated on the screen.

  7. Continue with configuration, press 2.

  8. Enter the configuration information. When prompted enter the following:

    • The logical name of the SAP HANA node.

    • The DPX tape pool to use with the SAP HANA database.

    • The DPX device pool to use with the SAP HANA database.

    • The DPX device to use with the SAP HANA database. During configuration, a template file is edited and copied to /opt/DPX/bin/dpxhdb.utl, a link is created, and the file /usr/sap//SYS/global/hdb/custom/config/global.ini is updated, where is the System ID.

  9. Installation and configuration is complete. Press 3 to exit the script.

Results

The script has installed and configured the DPX plugin for use with SAP HANA.

What to do next

Register a SAP HANA database system in SAP HANA Studio. For more information, see SAP HANA Studio best practices for DPX plugin.
