Enable Flow Control
The flow_control parameter in tibemsd.conf enables and disables flow control globally for the EMS server.
When flow_control is disabled (the default setting), the server does not enforce any flow control on destinations. When flow_control is enabled, the server enforces any flow control settings specified for each destination. See Configuration Files for more information about working with configuration parameters.
When you wish to control the flow of messages on a destination, set the flowControl property on that destination. The flowControl property specifies the target maximum size of stored pending messages for the destination. The size specified is in bytes, unless you specify the units for the size. You can specify KB, MB, or GB for the units. For example, flowControl = 60MB specifies the target maximum storage for pending messages for a destination is 60 Megabytes.
