Upgrading from Version 8 to Version 9

The following information details the steps that you must take in order to upgrade from Version 8 to Version 9 of Application Dispatcher.

Note: If you are upgrading from a release prior to Version 8, read the documentation for Release 8.2 of Application Dispatcher (at support.sas.com/rnd/web/intrnet), which describes upgrading from prior releases.

1. You must install the SAS 9 CGI Tools package on your Web server to access the SAS 9 Application Server. Note that the SAS 9 Application Broker and Load Manager will work with existing Version 8 Application Dispatcher services, so you can upgrade one or more services to SAS 9 while keeping other services at previous versions.

2. Upgrade socket services by editing the server start script and changing the path to the SAS executable from your Version 8 installation to the new SAS 9 executable. The following table lists the server start script for each operating environment.

   Operating Environment	Server Start Script
   Windows	appstart.bat
   UNIX	start.pl
   z/OS	APSTRTn JCL
   OpenVMS	start.com

   No changes are required for the appstart SAS program or other support files.

3. Upgrade pool and launch services by editing the Application Broker configuration file and changing the path of the SAS executable. No changes are required to the appstart SAS program or other support files.

4. If you are using Load Manager, modify your procedure for starting Load Manager to use the SAS 9 executable. On Windows, use the "Create a New IntrNet Service" utility to set up a SAS 9 Load Manager. Uninstall any existing Window Load Manager services from the Version 8 SAS System Start Menu. On UNIX you may need to edit the loadmgr script created by the inetcfg.pl utility.

5. If you are using Spawner for pool services, modify your procedure for starting the Spawner to use the SAS 9 executable.

6. Existing programs from earlier versions will run on the SAS 9 Application Server without modifications in most cases.
