ReceiveTimeout (MQLONG)

This specifies how long a TCP/IP channel waits to receive data, including heartbeats, from its partner before returning to the inactive state. It applies only to message channels and not to MQI channels.

The exact meaning of the ReceiveTimeout is altered by the value specified in ReceiveTimeoutType. ReceiveTimeoutType can be set to one of the following:
  • MQRCVTIME_EQUAL - this value is the number in seconds for the channel to wait. Specify a value in the range 0 - 999999.
  • MQRCVTIME_ADD - this value is the number in seconds to add to the negotiated HBINT, and it determines how long a channel waits. Specify a value in the range 1 - 999999.
  • MQRCVTIME_MULTIPLY - this value is a multiplier to apply to the negotiated HBINT. Specify a value of 0 or a value in the range 2 - 99.
The default value is 0.

Set ReceiveTimeoutType to MQRCVTIME_MULTIPLY or MQRCVTIME_EQUAL, and ReceiveTimeout to 0, to stop a channel from timing out its wait to receive data from its partner.

This attribute is supported on z/OS® only.

To determine the value of this attribute, use the MQIA_RECEIVE_TIMEOUT selector with the MQINQ call.
