Choosing SAS Integration Technologies or COM+ Pooling

The SAS Object Manager supports two different pooling mechanisms: SAS Integration Technologies and COM+ pooling. The main differences between the two pooling mechanisms are as follows:

• the way in which the pools are administered

• the way the programmer makes the call to get the pooled connection (workspace)

COM+ connection pooling has the following limitations:

• COM+ pooling cannot be used on Windows NT.

• COM+ does not allow multiple pooling configurations on the same machine (Windows 2000 only).

You might choose SAS Integration Technologies pooling instead of COM+ if any of the following are true:

• you use Windows NT

• you want to use multiple pools on the same machine

• you want to use the security mechanism that is available in SAS Integration Technologies pooling

• you want to use the same administration model for Java applications and COM applications

• you want to specify the pooling parameters in the source code

Note:    Java applications and COM applications cannot share the same pool; however, for SAS Integration Technologies pooling, they can share the administration model that is used for the pools.  

Note:    You cannot use SAS Integration Technologies and COM+ pooling configurations on the same machine.
