摘要: SOA is becoming prevalent in enterprise IT environments. As a result, component middleware are adding support for composite web services. Till recent past, most of these were employed tiered architectures. However, nature call graphs differs SOA. In this paper we revisit concurrency and deadlock issues that appear due to hosting applications on with thread allocation schemes. We propose novel scheme which performs an off-line analysis services equips containers essential information. At run-time, use information do not consult any central point or each other decisions. This makes our approach practical scalable. demonstrate, through simulations, can provide significant throughput improvements when compared traditional
