Retry considerations

If a link failure occurs during normal operation, a sender or server channel program will itself start another instance, provided that:

  1. Initial data negotiation and security exchanges are complete
  2. The retry count in the channel definition is greater than zero
Note:
For i5/OS, UNIX(R) systems, and Windows(R), to attempt a retry a channel initiator must be running. In platforms other than WebSphere MQ for iSeries, UNIX systems, and Windows systems, this channel initiator must be monitoring the initiation queue specified in the transmission queue that the channel is using.

Shared channel recovery on z/OS

See Shared channel recovery , which includes a table that shows the types of shared-channel failure and how each type is handled.
