Maintenance Configuration

Restarting Servers

After you install a maintenance release, you need to restart your SAS servers and spawners. If your SAS installation is a planned deployment, then you must restart the servers in a specific order. For information about how to start these servers, see Overview of Server Operation in the SAS Intelligence Platform: System Administration Guide.

Note: If you installed the maintenance release in a z/OS environment, see Starting and Stopping SAS Servers on z/OS in the SAS Intelligence Platform: System Administration Guide for instructions on how to restart SAS servers in that operating environment. [cautionend]

Restarting the SAS Metadata Server and Supporting SAS Servers

If your SAS installation is a planned deployment, then you must restart the servers in the following order:

SAS Metadata Server.
other SAS servers, such as the object spawner, the SAS/CONNECT spawner, the SAS OLAP Server, and the SAS Table Server. (Next, you will restart SAS Remote Services and the SAS Analytics Platform. For more information, see Restarting SAS Remote Services and Restarting the SAS Analytics Platform Server.)

Note: The SAS servers for your site depend on the SAS products that you have licensed. You might not have all of these servers at your site. If your site licenses products that depend on a particular server, you should apply any product updates to that server before restarting the server. If you do not apply these product updates now, then you will have to restart the server again after installing the product updates. For more information, see Product-Specific Updates and Post-Configuration Requirements.

Restarting SAS Remote Services

Restarting in a Windows Environment

If you are in a Windows operating environment and you configured SAS Remote Services to run as a Windows service, then do not use the Windows services manager or reboot to start SAS Remote Services. When you restart SAS Remote Services for the first time after installing the maintenance release, you must restart it by entering the following command at a DOS prompt: SAS-configuration-directory\Lev1\Web\Applications\RemoteServices\RemoteServices.bat restart.

Note: If you do not use this command to restart SAS Remote Services, then you will see errors when you start your Web application server, and the SAS Web applications will not start successfully. [cautionend]

Restarting in a UNIX Environment

If you are in a UNIX operating environment, then SAS Remote Services automatically restarts when you run the sas.servers script. For more information, see Use the sas.servers Script to Start, Stop, or Restart All Servers or to Display the Status of Servers in the SAS Intelligence Platform: System Administration Guide.

Restarting the SAS Analytics Platform Server

Why You Must Restart This Server

After installing a maintenance release, you must restart the SAS Analytics Platform server so that any SAS products that use this server (such as SAS Enterprise Miner, SAS Forecast Server, and SAS Model Manager) incorporate the changes from the maintenance release.

Restarting in a Windows Environment

To restart the SAS Analytics Platform server in a Window environment, use one of these methods:

From the Start menu, select Programs SAS SAS Configuration Config-Lev<num> Analytics Platform Server - Start.
At a command prompt, navigate to the SAS-configuration-directory\Lev1\AnalyticsPlatform directory and type AnalyticsPlatform.bat start.

Note: When you initially installed SAS, you might have selected Windows options: run as managed scripts or services in the SAS Deployment Wizard. If you selected this option, then the SAS Analytics Platform is run as a Windows Service. Generally, you can start the service by using the Services window. However, the first time that you restart the server after installing a maintenance release, you must use either the Start menu or a command prompt. If you restart the server from the Services window, then the SAS Analytics Platform does not pick up the updates in the maintenance release. After you have restarted the server from either the Start menu or at a command prompt once, the next time that you restart the server you can again use the Services window. [cautionend]

Restarting in a UNIX Environment

To restart the SAS Analytics Platform server:

Verify that your X server is running and is available.
At the UNIX prompt, navigate to the directory where the SAS Analytics Platform server is configured. Usually, this directory is SAS-configuration-directory/Lev1/AnalyticsPlatform.
If the SAS Analytics Platform server is currently running, type ./AnalyticsPlatform.sh stop.
To start the SAS Analytics Platform server, type ./AnalyticsPlatform.sh start.

Restarting Web Application Servers

Before you restart the Web application servers, you must complete the following tasks:
