What is SQL profiling in Oracle
A SQL profile is a collection of auxiliary data that is specific to a SQL statement; conceptually, it is to a SQL statement what statistics are to a table or index, and the database can use the data to enhance execution plans.
What is Oracle performance tuning
In other words, performance tuning makes it easier to access and modify the data stored in the database with the goal of enhancing query response times and application operations. Performance tuning is the process of optimizing Oracle performance by streamlining the execution of SQL statements.
What is Tkprof in Oracle with example
TKPROF takes longer to process a large trace file if the EXPLAIN option is used. RECORD. TKPROF determines execution plans by issuing the EXPLAIN PLAN statement after connecting to Oracle with the user and password specified in this parameter. The specified user must have CREATE SESSION system privileges.

- Utilize the Oracle explain plan to keep track of query performance.
- Look for database bottlenecks and assess the effect on performance.
- database management loads have increased.
How do you perform a performance tune in SQL query
It's vital you optimize your queries for minimum impact on database performance.
- Identify the needs of the business first.
- SELECT fields as opposed to SELECT *
- Do not use SELECT DISTINCT.
- Make joins using INNER JOIN rather than WHERE.
- Instead of using HAVING to define filters, use WHERE.
- Wildcards should only be used at the end of phrases.
What is the difference between SQL profile and SPM baseline
SQL plan baselines, on the other hand, limit the optimizer to only choosing from a set of accepted plans, whereas SQL profiles allow the optimizer to choose the best plan with the aid of additional information; this is why they can be shared.
What is Dbms_sqltune Accept_sql_profile
The function returns the name of the SQL Profile as a VARCHAR2 and the procedure accept_sql_profile creates the SQL Profile suggested by the SQL Tuning Advisor using the SQL Text provided by a SQL Tuning Task object.
How do I create a SQL baseline in Oracle
There are several ways to create a SQL plan baseline, including automatically for each statement, using a SQL Tuning Set (STS), using the cursor cache, and exporting from one database and importing into another.
