DB2 Connect Managed Access

DB2 Connect-managed access to database servers that implement Distributed Relational Database Architecture (DRDA) provides the following enhancements for Version 7.

Improved Support for Microsoft Transaction Server (MTS) and COM+ Technologies

DB2 Connect Version 7.2 implements enhancements to the distributed transaction processing. This improved support greatly reduces the possibility of deadlocks that can occur when multiple COM+ components, participating in the same global transaction, attempt to access the same DB2 for OS/390 data. The support is implemented in conjunction with the lock space sharing support for DB2 for OS/3900 version 6.1 database servers delivered through the following PTFs:

As a result of these enhancements, DB2 for OS/390 V6.1 database servers are now able to recognize multiple COM+ components participating in a transaction and to share the lock space between these COM+ objects. These enhancements ensure that resource requirements of one object do not prevent another object from acquiring the resources it needs. A limitation still exists where lock space cannot be shared between multiple members in a data sharing group in a Sysplex environment.

Multisite Update Improvements

The test connection feature of the Configure Multisite Update wizard has been expanded to permit testing of remote instances. In addition, you can associate a different user and password with each database entry in the test list. See the DB2 Connect User's Guide for more information.
