Synchronization tracing for Java programs is based on events generated when a thread attempts to acquire a Java Monitor. Both machine call stacks and Java call stacks are collected for these events, but no synchronization tracing data is collected for internal locks used within the JVM software. ...
To collect this data, specify on. collector synctrace threshold milliseconds Specify threshold in microseconds. The default value is 1000. collector synctrace threshold calibrate Threshold value will be calculated automatically.where:microseconds is the threshold below which synchronization wait events ...
A CountDownLatch is a versatile synchronization tool and can be used for a number of purposes. A CountDownLatch initialized with a count of one serves as a simple on/off latch, or gate: all threads invoking await wait at the gate until it is opened by a thread invoking countDown(). ...
having ThreadLocal in Java API makes it a lot more easy and standard. Think about ThreadLocal variable while designing concurrency in your application. Don't misunderstood thatThreadLocal is alternative of Synchronization, it all depends upon design. If design allows each thread to have there own...
Either the value pointed to by the third parameter (I/O AREA LEN) of the XRST CALL or the value of this parameter will be used, depending on which value is larger. MAXQn Is the maximum number of database calls with Qx command codes that can be issued between synchronization points. Th...
