Abstract
One aspect of the invention is a distributed object system comprising a plurality of resources and a plurality of transactions where at least some of the plurality of transactions make use of at least one of the plurality of resources. A transaction service runs on at least one computer and is operable to interact with the resources and transactions. The transaction service comprises a deadlock detector operable to determine whether deadlock will occur if one of the plurality of transactions waits to use a resource currently being used by another of the plurality of transactions. A roll back method is operable to roll back a particular transaction if the deadlock detector determines that deadlock will occur if that particular transaction waits to use a resource currently being used by another of the plurality of transactions.
