We have seen that sql baseline can be created with AWR using sql tuning set. With 12c, Oracle provided a way to directly create sql baseline using AWR without creating the tuning set. It is through procedure  DBMS_SPM.LOAD_PLANS_FROM_AWR. In this post, we will check how to create sql baseline from the AWR repository without STS […]

Sql baseline can be created from cursor cache, AWR and Sql tuning set. In this post, we will check out how to create sql baseline from Sql tuning set in Oracle How to create the Sql tuning set This can be done using the DBMS_SQLTUNE.CREATE_SQLSET procedure. In the following example, we’re creating a SQL Tuning […]

SQL Plan Baselines in Oracle Database are a method for maintaining the consistency of SQL statements’ performance.SQL baseline can be created from cursor cache, AWR, Sql tuning set etc. In this post, We will be looking at How to create sql baseline from the cursor cache in Oracle If you want to create a SQL […]

What is sql baseline? SQL Plan Baselines in Oracle Database are a way to maintain the performance stability of SQL statements. When an SQL statement is executed, the Oracle optimizer determines the optimal execution plan for that statement based on various factors such as statistics, system settings, and bind variables. However, sometimes the optimizer might […]

SQL Plan Management (SPM) in Oracle is a preventative mechanism that provides a level of control over the execution plans used by the Oracle optimizer. It ensures that regression due to changes in execution plans doesn’t occur, even as the database undergoes changes such as database upgrades, a gathering of new statistics, or changes to […]

A SQL Tuning Set (STS) in Oracle is a database object that includes one or more SQL statements along with their execution statistics and context. It provides a means to store SQL statements for future use, such as input to the SQL Tuning Advisor or SQL Access Advisor, capturing workloads to move them from one […]
