What's New in Application Server Administration for the SAS 9.2 Intelligence Platform
| Overview |
The SAS Intelligence Platform: Application Server Administration Guide explains how to administer a SAS Application Server.
This document contains new material about the following enhancements and changes to the SAS Intelligence Platform:
-
documentation enhancements to the SAS Intelligence Platform: Application Server Administration Guide
| Server-based Pooling Mechanism |
The SAS Pooled Workspace Server is a new SAS server type that exploits server-based pooling.
| Change to OBJECTSERVERPARMS System Option |
You no longer need to specify the OBJECTSERVERPARMS option, METAAUTOINIT, because it is on by default in SAS 9.2. (You can turn this option off by using the NOMETAAUTOINIT option.)
| New Configuration Tools |
These are the new SAS configuration tools:
-
SAS Deployment Wizard that is used to add new software and configurations
-
SAS Deployment Manager that is used to remove configurations
| Security Enhancements |
SAS contains these security changes:
-
server access security in which (primarily) the object spawner and the stored process server use metadata to verify that a user has permission to use a particular server
-
Integrated Windows Authentication (IWA) for single sign-on functionality for Windows desktop users
-
fewer operating system accounts are required to run SAS 9.2
-
internal accounts that SAS uses by default for some of the required user accounts (such as sastrust and sasadm)
| Load-Balancing Changes |
SAS contains these changes to server load balancing:
-
The stored process server and new pooled workspace server have load balancing enabled by default.
-
The object spawner uses its operator connection for load balancing out-of-the-box. Administrators no longer have to create a separate load-balancing connection.
| Grid Algorithm for Load Balancing |
SAS has a new load-balancing algorithm that supports Workspace servers running in a grid.
| New SAS Logging Facility |
SAS has a new logging facility controlled by the LOGCONFIGLOC system option that replaces the functionality of LOG and LOGPARM. (These traditional SAS log options still work, but SAS does not configure these by default anymore.) For more information, see The SAS Logging Facility in SAS Logging: Configuration and Programming Reference.
| Automated SAS Server Tier Configuration |
SAS has eliminated most post-install manual configuration scripts for the SAS server tier initial configuration through its new deployment tool, the SAS Deployment Wizard.
| Port Changes |
The following SAS default ports have changed:
-
The object spawner's managed ports can now share the same port.
-
The new SAS Pooled Workspace Server uses port 8701.
-
The new SAS Object Spawner port banks use ports 8801, 8811, and 8821.
-
The object spawner load balancing port, 8571, is no longer used.
| Documentation Enhancements |
The SAS Intelligence Platform: Application Server Administration Guide has been reorganized to reflect the new SAS features.
