The following information
details the steps that you must take to upgrade from Version 8 to
Version 9 of the Application Dispatcher.
Note: If you are upgrading from
a release earlier than Version 8, read the documentation for Release
8.2 of Application Dispatcher (at
support.sas.com/rnd/web/intrnet), which describes upgrading from previous releases.
-
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 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.
-
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:
No changes are required
for the
appstart SAS program or other support
files.
-
Upgrade the 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.
-
If you are using Load
Manager, modify your procedure for starting Load Manager to use the
SAS 9 executable. On Windows, use the
SAS/IntrNet Service Tasks in
the SAS Deployment Manager to set up a SAS 9 Load Manager. Uninstall
any existing Windows Load Manager services from the Version 8 SAS
system start menu. On UNIX, you might need to edit the
loadmgr script created by the Configure Load Manager
task in the SAS Deployment Manager.
-
If you are using Spawner
for pool services, modify your procedure for starting the Spawner
to use the SAS 9 executable.
-
Existing programs from
earlier versions can run on the SAS 9 Application Server without modification
in most cases.
