Using the Object Manager

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. [cautionend]

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