Following the section, "PointBase's Role in a DTP Environment," this chapter briefly describes Sun's Java Transaction API (JTA), the Java mapping for X/Open's XA Specification, and also the JDBC API Extensions for distributed transactions. Output(Interpreted): Rinkel failed to withdraw money.This chapter summarizes distributed transaction processing (DTP) environments and how to use PointBase Embedded or Server in a DTP environment.

In synchronized multithreading, this overhead time can be used to do other productive work until the waiting thread gets the key from the thread scheduler to get inside the synchronized area. The amount of time one task spends waiting for another is considered as overhead. ![]() The object in turn will choose 1 thread and pass it through the sensitive area.ĭoes synchronized multithreaded execution slower than the normal execution without multithreading? The class will select 1 object at a time. Now the sensitive area will be accessed by 5 threads at a time! To handle this problem engineers came up with the idea of static synchronization. Say we have 5 thread classes with 1 object each. Why should we use static synchronization? As it is a random process the output is different for each interpretation. The thread scheduler chooses the order of execution of the threads. An object can have multiple threads but the sensitive area can only be accessed by 1 thread at a time. Synchronization provides a lock to the object and declares a sensitive area (withdraw & deposit methods). Method 3: Incorporating synchronization with multithreading
