Setting Priority of Processes Related To Oracle - Should Improve The Performance Of The Oracle?

March 29, 2011 - PRLog -- Explain specific terms to start the operating system: planning and prevention. Suppose that the region we are talking about having a single processor. Any process that starts is to execute to a specific time, usually immediately. However, this system ultimately depends on the level of priority. High priority is greater attention to the process of the CPU. If two processes are designed to operate simultaneously, it would be a higher priority and once complete, or reaches a wait state (in the processor must wait a few resources are available for this ongoing process) goes to the second processor process. Although the second process is when the process is still scheduled for another kick and this third method has a higher priority than the second, the second process is interrupted while waiting and the processor executes the process of others. Therefore, the CPU time will be devoted primarily to the process of care with the same priority level until the some cases:
For instance, the process used to reach a wait state, another method with a higher priority level statistics upward and the service method complete.

When a process reaches a wait state or completed the process to the attention of the highest priority. The planning of the act of creating a process at some point it has, and focus is the usurpation of a timetable for the procedure by another process with higher priority.

As you can see, establishing priorities for the process and the right of first refusal. For example, the system processes the power saving mode and processor to start the process at the system level, user-level process, CPU, and the dream is to live without it. The process is available at the system level, user level to start the CPU. In general, the fact that the processes to perform basic tasks such as criticism, should be, in fact rather the system continues to operate normally.

But if the user deals with different levels, a higher priority to provide a clear advantage and should be used as a tool, if only there are many processes in experimental and control groups, select a handful of priority. In other words, each user-level process and give a priority and urgency of functionality. Benefit may be negative in cases of multiple processes of users are always up to compete against each other in different priorities, such as the passage of time the CPU to provide a process and a key to others. In addition, users can change the priority of the processor is planning to spend most of their time on specific processes, to the point that virtually ignores the rest, that is the frustration for users associated with these processes. As such, the first level is clearly to win only in some cases.

Each Oracle process should be left alone. Their priority should not be touched. Oracle server is a complex program of integrated planning functions. This means that the master on the same operating system, all user processes and Oracle processes behave according to their integrated functions. Make Oracle processes to create more or less harmful to the proper functioning of the Oracle server.

Unix provides a convenient control for setting priority levels for user processes. This command sets the kindness of the method. The lower part of the kindness, the more aggressive approach is in terms of monopolizing the processor. If your users do not oracle, CPU-intensive functions on your server database, and thus inadvertently slow database, you can increase the kindness of these processes so that all processes related to Oracle for maximum CPU specific. So many flavors of Unix command renice support, which lets you change the priority levels of processes already running. So if you find that the database performance is poor because of a method using all the CPU high, you can renice to make it more passive.
