DSNJ316I SYSTEM QUIESCE ALREADY IN PROGRESS

Explanation
 An attempt was made to issue an -ARCHIVE LOG command
with the MODE(QUIESCE) option when a system quiesce was already in
progress. The system quiesce could be the result of processing by
another -ARCHIVE LOG MODE(QUIESCE) command, or by a -STOP DB2 MODE(QUIESCE) command.

System action
 Command processing will terminate.  The system
quiesce currently in progress will continue.
