Controlling the SAS Embedded Process

The SAS Embedded Process starts when a query is submitted using the SAS_EP procedure. It continues to run until it is manually stopped or the database is shut down.

Note: Starting and stopping the SAS Embedded Process has implications for all scoring model publishers.

Note: Manually starting and stopping the SAS Embedded Process requires HANA database administrator user permissions.

When the SAS Embedded Process is installed, the ShutdownSASEP.sh and StartupSASEP.sh scripts are installed in the following directory. For more information about these files, see Installing the In-Database Deployment Package for SAP HANA.

/SASEPHOME/SAS/SASTKInDatabaseServerForSAPHANA/9.4/

Note: You can find the location of SASEPHome by using the following command:

ls -l /usr/local/bin

ShutdownSASEP.sh shuts down the SAS Embedded Process. It is designed to be used to shut down the SAS Embedded Process prior to a database upgrade or re-install. This script should not be used as part of the normal operation.

Use the following command to shut down the SAS Embedded Process.

/SASEPHOME/SAS/SASTKInDatabaseServerForSAPHANA/9.4/ShutdownSASEP.sh

Note: The -verbose option is on by default and provides a status of the shutdown operations as they occur. You can specify the -quiet option to suppress messages.

Tip

You do not have to manually restart the SAS Embedded Process. The SAS Embedded Process starts when a query is submitted using the SAS_EP procedure.

StartupSASEP.sh manually starts the SAS Embedded Process. It is designed to be used to manually start the SAS Embedded Process and only after consultation with SAS Technical Support. This script should not be used as part of the normal operation.

Use the following command to manually start the SAS Embedded Process.

/SASEPHOME/SAS/SASTKInDatabaseServerForSAPHANA/9.4/StartupSASEP.sh

Note: The -verbose option is on by default and provides a status of the start-up operations as they occur. You can specify the -quiet option to suppress messages.
