The information in this article applies to:
This article was previously published under Q290511 SYMPTOMS
When you use transactions from within a COM+ application that utilizes Microsoft Data Access Components (MDAC) pooling, you may receive the following error message:
-2147168246 'Failure enlisting in Resource Manager'
CAUSE
This error message occurs because new connections are opened and enlisted in an existing transaction. Databases such as Oracle and DB2 may experience problems when COM+ tries to use multiple connections on the same transaction.
In Microsoft Windows 2000 SP1 and earlier, the implementation of the COM+ Dispenser Manager requests a connection from the resource manager regardless of the transaction context. When a connection must be allocated, the Dispenser Manager iterates through the list of free database connections. The Dispenser Manager may enlist a new connection for the transactional method call despite the fact that there may be free connections that are already enlisted in that transaction.
