PowerProtect Data Manager 19.11 SAP HANA User Guide

PDF

Decommission the SAP HANA agent version pre-19.8

Learn how to manually decommission the client with SAP HANA agent version earlier than 19.8.

Steps

  1. To identify the SAP HANA instances, run the following command: 
    /usr/sap/hostctrl/exe/saphostctrl -function ListInstances
  2. Locate the ppdmconfig directory for each instance. The directory pathname includes the instance name. For example, instances I1 and I2 have the following ppdmconfig directories:

    /usr/sap/I1/SYS/global/ppdmconfig/

    /usr/sap/I2/SYS/global/ppdmconfig/

  3. In the ppdmconfig directory for each instance, search for the UTL files with names ending in _data_user.utl and _data_auto.utl. For example:

    1. In the /usr/sap/I1/SYS/global/ppdmconfig/ directory, run the following commands to search for the UTL files: 

      ls *_data_user.utl
ls *_data_auto.utl

    2. In the /usr/sap/I2/SYS/global/ppdmconfig/ directory, run the following commands to search for the UTL files: 

      ls *_data_user.utl
ls *_data_auto.utl
  4. Open each UTL file in an editor, add the following comment, and save the file:
    #<hostname> is no longer using this file <current_date_and_time>
    NOTE This comment is added because the UTL files are located on a shared drive and used by multiple nodes.
  5. Delete the following files on the local drive:

    /opt/dpsapps/dbappagent/saphana/.ppdmintegrated

    /opt/dpsapps/dbappagent/saphana/sqlite/*

Next steps

After the client is decommissioned, PowerProtect Data Manager deletes the remaining backup copies from the DD system according to the schedule. However, the SAP HANA catalog might still have entries for the deleted backup copies. You must clean up these catalog entries manually by using the SAP HANA Studio or hdbsql command.

After you decommission the SAP HANA client from PowerProtect Data Manager, the agent software binary remains on the client host. You can configure the client host as a stand-alone agent by following the instructions in the PowerProtect Database Application Agent Installation and Administration Guide. The previous .utl files are located under the directory /usr/sap/<SID>/SYS/global/ppdmconfig. Use the configuration files with the auto.utl file name suffix to perform the configuration with SAP HANA Studio.
