two-phase commit การใช้

• How to configure a two - phase commit transaction in websphere
• To support two - phase commit , you ll need the following software
• For database two - phase commit
• Two - phase commit
• Applications that require two - phase commit service under a transaction manager should use
• First , find out if your environment meets the prerequisites to support two - phase commit
• For more information about in - doubt transactions , see the " two - phase commit " section in
• The transaction must be escalated to dtc , as a full distributed two - phase commit transaction
• The data modifications are then immediately propagated to the publisher using two - phase commit protocol
• When the application commits the transaction , the transaction manager initiates the two - phase commit protocol
• The data modifications are then immediately propagated to the publisher using the two - phase commit protocol
• Interfaces deal with managing distributed transactions across various back ends that support a two - phase commit protocol
• In this article , gang focuses on xa distributed transactions and on the inner workings of the two - phase commit protocol
• In summary , the two - phase commit protocol and the resource managers combine to make transactions atomic and durable . the transaction
• Using the websphere global transaction , where two - phase commit protocol is in place , will significantly decrease the overall performance
• If another resource becomes involved in the transaction , you have forced an unnecessary two - phase commit , causing an additional prepare flow
• This is achieved by managing the commit process in two phases the prepare phase and the commit phase , which is known as a two - phase commit
• In addition , you should only reenlist unresolved transactions logged by a resource manager during the initial prepare phase of a two - phase commit
• Sql server 2005 requires ms dtc in the cluster for distributed queries and two - phase commit transactions , as well as for some replication functionality
• If it detects that all the resources involved in the transaction are the same , it can skip the two - phase commit and let the resource manager handle the transaction by itself
