Export SQL Plan from One Database to Another
Overview
Transferring an SQL plan between databases is a critical task for database administrators and developers who seek to optimize query performance across different environments. Efficiently exporting and importing SQL execution plans can ensure consistency and aid in troubleshooting performance issues.
This process requires a clear understanding of the SQL plan's components and the steps involved in moving it securely from one database to another. By mastering this skill, professionals can save time and reduce errors in database management.
In the following sections, we will delve into the methods for exporting SQL plans and highlight how Sourcetable simplifies this process by allowing you to export your data directly into a spreadsheet-like interface in real-time.
Export SQL Plan from One Database to Another
Introduction to SQL Plan Baselines Transfer
Transport SQL PLAN Baselines efficiently between databases to maintain optimal query performance. This process is essential for leveraging successful execution plans across different environments.
Identify SQL Plan Baseline
For a SQL plan with the handle SYS_SQL_58d940ad7b3ac047, ensure all associated multiple plans are included for the transfer.
Utilize SQL Plan Management (SPM)
SPM is the tool of choice for creating and transferring execution plans. It preserves good execution plans, generated from historical data, for future use.
Transfer Using SPM's Baseline Feature
Transfer your execution plan to another database instance by employing SPM's baseline feature, which is specifically designed to handle such tasks.
Frequently Asked Questions
What privileges are required to export SQL plan from one database to another?
The user must have 'administer sql management object' privileges to execute these steps.
What are the steps involved in exporting SQL plan from one database to another?
The steps include creating a staging table, packing baselines in the source database, exporting the staging table, importing the staging table into the target database, and unpacking the baselines.
Can a staging table be created in the SYS schema?
No, a staging table cannot be created in the SYS schema.
Is it possible to directly use a query plan from one database's plan cache in another database?
No, it is not possible to re-use a query plan from the plan cache from one database in another database due to the potential for different data and the need for different plans.
Can SQL plan baselines be moved between databases of different platforms within Oracle Database?
Yes, moving SQL PLAN Baselines between databases works for any platform within Oracle Database.
