Parallel Servers in Oracle Database
Many think that processing a activity or work parallely will be more effective then performing it sequentially(serially),Even we do apply for most of the cases.Since, in parallel processing , the work is divided among the multiple resources and each resource will take care of their allocated work and finally results from all of them are merged as one final result. Oracle has also introduced Parallel processing technique which is called as Parallel servers or Parallel query servers, where work is divided among multiples resources , resources here mean threads which are capable of doing working dependently. But when it comes to implementing parallel processing techniques in machines , it is not as easy as what we can do as human, Since the machines need to be guided so that each parallel thread should coordinate with other whenever required. Lets discuss in depth about Parallel processing technique i.e Parallel servers implemented in Oracle Database...
