Unresolved units of work

An unresolved unit of work, also known as an "in-doubt thread", is one that is in the second pass of the two-phase commit operation. Resources are held in WebSphere MQ on its behalf. To display unresolved units of work, use

DISPLAY CONN(*) WHERE(UOWSTATE EQ UNRESOLVED)

External intervention is needed to resolve the status of unresolved units of work. This might only involve starting the recovery coordinator (CICS, IMS, or RRS) or might involve more, as described in the following sections.
