PowerProtect Data Manager automatically creates two configuration files on the SAP HANA server 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.
PowerProtect Data Manager automatically creates the two configuration files on the SAP HANA server 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 descriptions and valid values
Parameter: CLIENT
Specifies the name of the client directory to store the backup save sets on the
protection storage 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:
0 (default) = The software does not generate debug messages.
1-9 = The software writes the specified level of debug messages in the debug log. The level of detail in the messages increases with a higher debug level setting.
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:
FALSE (default) = The software does not generate debug messages.
TRUE = The software writes debug messages in the debug log. The
DEBUG_LEVEL setting determines the level of the debug messages.
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 application agent uses to write the backup data to
protection storage.
