What happens if I enable auto DOP?
With Auto DOP since the optimizer is deciding when to use parallel execution and the DOP to use, depending on how you configure Auto DOP, the number of parallel statements and their DOPs may change when you enable it. Some serial statements may start running in parallel, some parallel statements may start running serially.
What is auto DOP vs manual DOP?
As opposed to manual DOP it does not require table/index decorations or hints. Here is the basic decision flow for a SQL statement with Auto DOP. The optimizer first generates a serial plan for the SQL statement and estimates the execution time. If the estimated execution time is less than the specified threshold the statement runs serially.
How does auto DOP work with parallel statement queuing & database resource manager?
Auto DOP relieves the burden of deciding on a DOP for each statement and enables you to focus on optimizing the whole workload together with Parallel Statement Queuing and Database Resource Manager. We will talk about how these work together in later posts.
What is automatic DOP in Oracle?
Automatic DOP whichis – as the name says – a way of having Oracle determine the degree of parallelism depending on the nature of the operations to be performed and the sizes of the objects involved. The decision is made based on various initialization parameter settings. 1. PARALLEL_DEGREE_POLICY. It can have 3 values : MANUAL, LIMITED and AUTO.
Does DBRM initialization parameter affect auto DOP?
This parameter has no effect on statements not using Auto DOP. So, for any SQL statement that the optimizer decides to run in parallel with Auto DOP, it takes into account the initialization parameters, DBRM settings, system and object statistics, and HW characteristics to compute the DOP.
What is a limited DOP parameter?
When you set this parameter to LIMITED, Auto DOP is applied to statements accessing tables/indexes decorated with the default DOP unless those statements set a specific DOP using hints. For all other statements manual DOP will be used.
