You can change the connection behavior for TCPIPServer nodes by using the mqsichangeproperties command.
Any changes that you make affect current connections in the integration server, and are temporary. When the integration server is next started, all connections are active again.
TCP/IP connection behavior is managed by the server connection manager. To change the connection properties, you must run mqsichangeproperties and specify the integration node name, -o, and the -n or -v parameters.
-o TCPIP/<action>/Server
Where <action> can take one of the following values:
mqsichangeproperties IBNODE -e default -o TCPIP/start/Server -n port -v 1445
mqsichangeproperties IBNODE -e default -o TCPIP/stop/Server -n port -v 1445
mqsichangeproperties IBNODE -e default -o TCPIP/quiesce/Server -n port,quiesceTimeoutSec -v 1445,30
