-918 THE SQL STATEMENT CANNOT BE EXECUTED BECAUSE A CONNECTION HAS BEEN LOST

Explanation
 Execution of the SQL statement failed because
a communications link between the local DB2® and
at least one remote server no longer exists. A previous failure  caused
this condition.

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

Programmer response
 In general, an application program should
issue a static ROLLBACK. Attempts by the application to issue SQL
statements other than static ROLLBACK might fail. Once the static
ROLLBACK is issued, the application can resume execution.
 SQLERRP
contains the name of the module that detected the previous failure
and placed the application in the must-abort state.
