This setting enables Auto DOP, parallel statement queuing, and in-memory parallel execution, similar to the AUTO value. In addition, performance feedback is enabled. The
Oracle 11g Release 2 (11.2) introduced some big changes associated with the control of parallel execution. This article gives an overview of Auto DOP and Parallel Statement Queuing, which can be used to give a degree of control

If you hit a bug, you can still use Auto DOP for users that will not be impacted by it. Resource manager can be used to limit DOP for a specific group of users. This can be a good idea with

- 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.
- 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.
- How do I set a DOP in Oracle Database?
- Tables and indexes that have a DOP specified use that explicit DOP setting. If you want Oracle Database to automatically decide the DOP only for a subset of SQL statements that touch a specific subset of objects, then set PARALLEL_DEGREE_POLICY to LIMITED and set the parallel property without specifying an explicit DOP on that subset of objects.
