You might decide that
you need add another server in your logical server. The most common
scenario is that you want to establish a server cluster to achieve
load balancing. If you are adding one of the workspace servers or
a stored process server, then you must also add an object spawner
to manage it, unless there is already a spawner on the machine. Follow
these steps to add a new server and—if necessary—an
object spawner to an existing logical server:
-
The machine on which
you want to add the new server should have a network connection to
your site's SAS Software Depot. If it does not, then you must find
a way to get the depot to the machine on which you want to create
the new server.
-
Make sure that you have
first installed the new server on the new machine by referring to
Adding SAS Products in SAS Intelligence Platform: Installation and Configuration Guide. When installing the new server, follow these guidelines:
-
If you are installing
one of the workspace servers or a stored process server, then you
also need an object spawner to be on the new machine. Do one of the
following:
-
If you:
-
then when installing
the new server with the SAS Deployment Wizard, make sure that you
choose both
Install SAS Software and
Configure
SAS Software.
-
Do not need an object spawner:
then when installing
the new server with the SAS Deployment Wizard, make sure that you
choose
Install SAS Software and deselect
Configure
SAS Software.
-
When you see the wizard's
Specify
Configuration Information dialog box, make sure that
the configuration directory that you enter matches the SAS configuration
directory on the machine that contains the pre-existing SAS Application
Server. For example,
C:\SAS\Config
.
-
When you see the wizard's
Select
Products to Configure dialog box, check
SAS
Object Spawner only. Server configuration is described
in later steps in this topic.
-
Create a configuration
path on the new machine that matches the configuration path on the
pre-existing machine.
For example, if the
configuration path on machine 1 is
C:\SAS\Config\Lev1
,
then create the same path on machine 2.
-
Copy the configuration
directories of the pre-existing SAS Application Server to the new
machine.
For example, on Windows,
copy the following directory from machine 1 to machine 2:
C:\SAS\Config\Lev1\SASApp
-
Copy the configuration
directories of any pre-existing logical servers to which you are adding
additional servers, to the new machine.
For example, if you
are adding another workspace server, copy the following directory
from machine 1 to machine 2:
C:\SAS\Config\Lev1\SASApp\WorkspaceServer
-
Start SAS Management
Console and connect to a metadata repository.
-
In the SAS Management
Console navigation tree, select and expand the
Server
Manager, and locate the SAS Application Server under
which you want to add the new server.
-
Expand the SAS Application
Server and locate the logical server under which you want to add the
new server.
-
With the logical server
selected, choose
ActionsAdd Server from the menu bar.
The New Server Wizard
is displayed.
-
Enter a name (required)
and a description (optional) for the new server. The server name should
indicate the machine, server type, and unique port on the new machine
for the server. When you are finished, click
Next.
The name that you provide
will be the name of the server that is displayed in the SAS Management
Console Server Manager plug-in.
-
Specify whatever configuration
information is required for the type of server that you are adding.
The number of wizard pages that you see and the information that
you must supply, varies depending on the server type. Use the wizard
online Help if necessary. For information about object server parameters,
see
OBJECTSERVERPARMS System Option.
Note: To avoid a configuration
error and failed client connections, you must enter user credentials
when defining a pooled workspace and a stored process server.
-
When you see a wizard
page that states that you have successfully completed a new server
definition, review the information supplied and do one of the following:
-
click
Finish to
add the new server and close the New Server Wizard.
-
click
Back to
go to an earlier wizard page to change an input.
