The display qmstatus command can be used to determine if a queue manager is running or stopped. In this example, the queue manager named MANAGER01 is running.

echo "display qmstatus" | runmqsc MANAGER01
. . .
QMNAME(MANAGER01)                        STATUS(RUNNING)

In this example, the queue manager named MANAGER01 is running as standby.

echo "display qmstatus" | runmqsc MANAGER01
. . .
QMNAME(MANAGER01)                        STATUS(Running as standby)

In this example, the queue manager named MANAGER01 is running elsewhere.

echo "display qmstatus" | runmqsc MANAGER01
. . .
QMNAME(MANAGER01)                        STATUS(Running elsewhere)

In this example, the queue manager named MANAGER01 was ended normally.

echo "display qmstatus" | runmqsc MANAGER01
. . .
QMNAME(MANAGER01)                        STATUS(Ended normally)

The all option can be used to include additional fields in the output.

echo "display qmstatus all" | runmqsc MANAGER01
. . .
QMNAME(MANAGER01)                       STATUS(Running)
