How to fix this error?

The error may have been caused by the following:
- The connection could not be initialized because the
Gateway was not active. Please ask the person responsible
for the system to check the status of the gateway. If the
gateway is active, allocation has been unsucessful.
- The connection could not be allocated. Please execute
the function again. If you still have no success, you
should proceed as follows:
- The communication system in the subsystem is not active.
Please check the status of the communication system at
a terminal, and carry out a restart if necessary.
- If the communication system is active in the subsystem, then
all defined communication channels to the subystem are occupied
by other applications. Please deactivate any connections which
are not needed, and try again to set up a connection. Ask the person
responsible for the system to define additional channels if they are
a permanent requirement.
