Improved administering of shared resources in a computer system. In a preferred embodiment, transaction throughput is improved and potential starvation eliminated by a ticket mechanism. The ticket mechanism provides a wait counter and a service counter. When a requested transaction fails, a wait counter is incremented and a wait value is sent to the requesting transaction source. As transactions are completed at the resource, the service counter is incremented and its value broadcast to transaction sources sharing that resource. When a source holds a wait count value that equals the service count value, the source can retry the transaction successfully.
