DB2 Connect support for loosely coupled transactions

 

The support within DB2 Connect™ for loosely coupled transactions is intended for users who implement XA distributed applications that access DB2® for i5/OS Version 5 Release 4 or later; and DB2 Universal Database (UDB) for OS/390® and z/OS® Version 7 or later. This support allows different branches of the same global transaction to share lock space on DB2 for OS/390 and z/OS.

Support for loosely coupled transactions is intended for .NET and COM+ applications.

This feature reduces the window where one branch of a distributed transaction encounters lock timeout or deadlock as a result of another branch within the same global transaction.
