Ensuring that your database meets the service level agreements (SLAs) and expectations of your users and customers.
Detecting and resolving any performance problems or bottlenecks that may affect the database response time, throughput, or availability.
Identifying and eliminating any resource wastage or inefficiency that may increase the operational costs or risks of your database.
Planning and forecasting the future capacity and growth needs of your database.
To monitor and tune Oracle Database 11g effectively, you need to collect and analyze various types of information about the database state, workload, and behavior. This information can be obtained from different sources, such as:
The database itself, which provides many built-in tools and views to monitor its own performance and health.
The operating system, which provides information about the CPU, memory, disk, and network utilization of the database server.
The application, which provides information about the user transactions, queries, and sessions that interact with the database.
The network, which provides information about the latency, bandwidth, and reliability of the communication between the database server and the clients.
What are Oracle 11g Monitoring And Tuning Scripts?
Oracle 11g Monitoring And Tuning Scripts are a collection of SQL scripts that can help you query and analyze the information from the sources mentioned above. These scripts can help you perform various tasks related to monitoring and tuning Oracle Database 11g, such as:
Checking the general database state and workload.
Monitoring the database performance metrics and alerts.
Diagnosing the performance problems using Automatic Database Diagnostic Monitor (ADDM).
Using advisors to optimize database performance.
Monitoring and managing the memory, storage, undo, redo, temp, cache, latch, lock, session, cursor, wait, event, job, object, index, tablespace, datafile, controlfile, logfile, directory, pipe, synonym, privilege, role, user, profile, parameter, option components of the database.
Comparing the performance of different time periods or databases.
Generating reports and charts for performance analysis.
The scripts are organized into categories based on their functionality and purpose. Each script has a descriptive name that indicates what it does. For example:
access.sql: Shows who is accessing what in the database.
active_sessions.sql: Shows active sessions in the database.
cache_hit_ratio.sql: Shows the cache hit ratio for buffer cache and library cache.
db_info.sql: Shows general information about the database.
index_usage.sql: Shows index usage statistics for tables.
parameters.sql: Shows all parameters for the database or a session.
rbs_stats.sql: Shows rollback segment statistics.
table_stats.sql: Shows table statistics such as number of rows, blocks, extents etc.
How to Use Oracle 11g Monitoring And Tuning Scripts?
To use Oracle 11g Monitoring And Tuning Scripts, you need to have access to a SQL*Plus session connected to the target database as a user with sufficient privileges. You can then run any script by typing its name followed by a semicolon (;) at the SQL prompt. For example:
SQL> access.sql;
Some scripts may require you to enter some input parameters, such as a table name, a session ID, a time interval, etc. You can enter these parameters when prompted by the script. For example:
SQL> index_usage.sql; Enter table name: EMP
The output of the scripts will be displayed on the screen or written to a file, depending on the settings of SQL*Plus. You can also use the SPOOL command to save the output to a file. For example:
SQL> SPOOL db_info.txt SQL> db_info.sql;
SQL> SPOOL OFF
You can also customize the scripts by modifying the SQL queries or adding new features according to your needs. However, you should always test the modified scripts before using them in production.
