How to Control Database Updates in an Active-Active Cluster (Doc ID 1058516.1)

Last updated on OCTOBER 30, 2019

Applies to:

Oracle(R) BPEL Process Manager 10g - Version to [Release AS10gR3]
Information in this document applies to any platform.


You have implemented a BPEL process with a database adapter that runs a stored procedure in the database, and deployed it to your active-active cluster.  Since the target is an active-active cluster, instances of your process can be activated on both nodes resulting in a race condition.  So you need to control access to the stored procedure to ensure that it runs "single-thread."

(The approaches described below addresses the example of the stored procedure specifically, but clearly they can be used to accomplish the same thing in other situations which require single-thread execution in a clustered environment.)
