PowerProtect Data Manager 19.10 SAP HANA User Guide
Modify the configuration file parameter settings
PowerProtect Data Manager automatically creates two configuration files for each database when you add the assets to a protection policy and auto-configuration is triggered. If required, you can modify the settings of certain parameters in one of the configuration files.
Add a protection policy for SAP HANA database protection provides information about adding the assets to a protection policy.
PowerProtect Data Manager automatically creates the two configuration files as follows, where <SID> is the system ID of the SAP HANA system. These configuration file pathnames are predetermined and cannot be changed:
- User configuration file: /usr/sap/<SID>/SYS/global/ppdmconfig/<SID>_<database_name>_data_user.utl
- Auto configuration file: /usr/sap/<SID>/SYS/global/ppdmconfig/<SID>_<database_name>_data_auto.utl
In the user configuration file, <SID>_<database_name>_data_user.utl, you can optionally modify the parameter settings that are described in the following table.
NOTE The parameters in the auto configuration file
<SID>_<database_name>_data_auto.utl are set automatically and cannot be changed. The parameter settings in
<SID>_<database_name>_data_user.utl override the settings in
<SID>_<database_name>_data_auto.utl.
To enable debug logging during the SAP HANA backups, set the DEBUG_LEVEL and DPRINTF parameters as described in the following table. As required for centralized backups, ensure that you also select Troubleshooting under Advanced Option in the Add Primary Backup dialog box in the PowerProtect Data Manager UI, as described in Add a protection policy for SAP HANA database protection.
To specify a parallelism value for self-service backups, set the PARALLELISM parameter as described in the following table.
|
Parameter: CLIENT Specifies the name of the client directory to store the backup save sets on the DD system.The default name is <SID><database_name>, which is automatically set in the CLIENT parameter in the configuration file <SID>_<database_name>_data_auto.utl. NOTE To override the default
CLIENT parameter value, ensure that you set the
CLIENT parameter in the
<SID>_<database_name>_data_user.utl file.
Valid value: Name of the client directory where the backup save sets are stored. |
|
Parameter: DEBUG_LEVEL Specifies the level of debug messages that the PowerProtect Data Manager software writes in the debug log file with a .log file name extension in the /opt/dpsapps/dbappagent/logs directory.NOTE The
DEBUG_LEVEL parameter must be set in the
<SID>_<database_name>_data_user.utl file.
Valid values:

Parameter: DPRINTF Specifies whether the PowerProtect Data Manager software writes debug messages in the debug log file with a .log file name extension in the /opt/dpsapps/dbappagent/logs directory.NOTE The
DPRINTF parameter must be set in the
<SID>_<database_name>_data_user.utl file.
Valid values:
|
|
Parameter: PARALLELISM Specifies the parallelism value for self-service SAP HANA backups. The parallelism value controls the number of parallel streams that the SAP HANA agent uses to write the backup data to DD.NOTE For centralized backups, you must set the parallelism value in the
PowerProtect Data Manager UI as described in
Enable multi-stream backups for SAP HANA protection policy.
