-948 DISTRIBUTED OPERATION IS INVALID

Explanation
 The unit of work was initiated before DDF was
started, and the application attempted to perform a distributed operation.
The unit of work must be terminated by a rollback operation.

System action
 In the IMS™ and CICS® environments, all SQL statements
are rejected until a rollback occurs. In the other environments, all
SQL statements other than a static ROLLBACK are rejected until a static
ROLLBACK is executed.

Programmer response
 An application that performs local database
updates before DDF is started cannot perform distributed operations
within the same unit of work.  The current unit of work must be terminated
by a rollback operation and a new unit of work must be initiated before
any SQL operations can be performed.
 Restart the current unit
of work.
