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 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.
