Fields for the Pooled Logical Server and Puddle Definitions

You can only convert SAS Workspace Servers to pooled logical servers.

The pooled logical server definition contains information for an instance of a pooled logical server. The pooled logical server is defined using the fields listed in the following table. For each field, the table shows the following information:

  • the name that identifies the field in SAS Management Console. Under each field name, the table shows the location of the corresponding properties tab and field name in the SAS Management Console application.

  • "Required" or "Optional" to indicate whether the field is required.

  • a definition of the field.

For general information about the use of logical servers, refer to Overview of Pooling.
