TransactionMode

HKLM\SOFTWARE\Microsoft\MSMQ\Parameters

Data type Range Default value
REG_SZ DefaultCommit | (blank) DefaultCommit

Description

Uses the default-abort mode to process transactions.

For performance reasons, the mode has been changed to default-commit in Message Queuing. When the value of this entry is blank, the service uses the previous default-abort mode. When the value of this entry contains DefaultCommit, the service uses the new default-commit mode. The normal upgrade from Windows NT 4.0 sets the value of this entry to DefaultCommit.
