A distributed transaction submission method and device

Abstract

The embodiment of the present invention provides a method and device for submitting a distributed transaction, including: after receiving the request to submit the global transaction, all XA resources participating in the global transaction submit the modification related to the global transaction sequentially by means of one-stage transaction submission Go to the master node of the XA resource where it is located, and record the reverse operation in the transaction log of the read-write separation agent of the XA resource where it is located; after all XA resources participating in the global transaction successfully submit the global transaction, in each XA resource participating in the global transaction, Clear the reverse operation from the transaction log of the read-write separation agent of the XA resource, and notify the master node of the XA resource to synchronize the submission of the global transaction to the slave node of the XA resource. The distributed transaction submission method and device provided by the embodiments of the present invention reduce the number of interactions with each XA resource in the transaction submission process, reduce the locking time for each XA resource, and greatly improve the processing efficiency of global transactions.

Description

technical field [0001] The invention relates to the field of transaction processing, in particular to a distributed transaction submission method and device. Background technique [0002] The XA two-phase transaction commit protocol is a two-phase commit protocol defined by the X / OPEN organization and used in a distributed transaction environment to ensure data consistency and integrity among multiple resources participating in the transaction. At present, mainstream databases and message middleware servers all support the XA protocol. [0003] When the transaction needs to be committed, call XAResource.papare of each resource XAResource participating in the transaction to collect voting results. If all XAResources return XAResource.XA_COMMIT, the transaction can be committed, and XAResource.commit is called to commit the transaction. If in the first phase, the XAResource participating in the transaction has a disagreement commit, call XAResource.rollback to roll back the t...

Problems solved by technology

[0012] The embodiment of the present invention provides a distributed transaction submission method and device to solve the problem that in the current two-phase transaction submission protocol, each XA resource participating in the two-phase transaction needs to be locked for a long time, which affects the throughput of transaction processing Rate, leading to the defect of low execution efficiency of two-phase transactions
