Oracle Performance Tuning Training FAQ'S

What is proactive tuning and reactive tuning?

Using Proactive Tuning, the application designers may then decide which Oracle features and system resources will best meet their goals during design and development. Reactive tuning uses the bottom-up approach to find and fix bottlenecks. As a result, Oracle ought to operate more swiftly.

Explain rule-based optimizer and cost-based optimizer?

Oracle decides how to retrieve the necessary data whenever a valid SQL training Hyderabad statement is processed. This decision can be made using one of two methods:

Rule-Based Optimizer: If the server has no internal statistics relating to the objects referenced by the statement, then the RBO method is used. This method will be deprecated in future releases of Oracle.

Cost-Based Optimizer: The CBO method is used if internal statistics are present. The CBO checks several possible execution plans and selects the one with the lowest cost based on the system resources.

Explain union and intersect with examples?

UNION: The UNION operator is used to combine the result-set of two or more SELECT statements Tables of both the select statement must have the same number of columns with similar data types. It eliminates duplicates.

Syntax: SELECT column_name(s) FROM table_name1 UNION SELECT column_name(s) FROM table_name2
Example: SELECT emp_Name FROM Employees_india UNION SELECT emp_Name FROM Employees_USA

INTERSECT allows combining results of two or more select queries. If a record exists in one query and not in the other, it will be omitted from the INTERSECT results.

What is the difference between open_form and call_form? What is new_form built-in in oracle form?

The specified form is opened by open_form. Call_form keeps the parent form active in addition to opening the specified form. When new_form is called, the old indicted form is closed by freeing memory while the new one is opened. The same Run form settings as the parent form are used to launch the new form.
