In Oracle, a listener is a background process that listens for incoming client connection requests and establishes connections between clients and database instances. Checking the status of the listener is important for ensuring that the database is accessible to clients and that the listener is functioning correctly.

There are several ways to check the status of the listener in Oracle. One way is to use the lsnrctl command-line utility. The lsnrctl command can be used to start, stop, and check the status of the listener. To check the status of the listener, use the following command:

Oracle Tablespaces: An In-Depth Guide on How to Check Their Usage

September 12, 2024March 18, 2023 by admin

Within an Oracle database, a tablespace is a logical storage unit composed of one or more data files. Different types of Oracle database objects, such as tables, indexes, and temporary segments, can reside in a tablespace. Checking the tablespace is crucial because it helps the database administrator (DBA) monitor the space usage, identify potential issues, and ensure optimal performance of the database.

There are several ways to check tablespace in Oracle, including using Oracle Enterprise Manager, SQL queries, and operating system commands. Oracle Enterprise Manager provides a graphical user interface (GUI) that allows DBAs to easily view and manage tablespaces, including their size, usage, and status. SQL queries can also be used to retrieve information about tablespaces, such as the following query that displays the size and usage of all tablespaces in the database:

SELECT tablespace_name, total_space, ROUND((used_space / total_space) * 100, 2) AS pct_used FROM dba_tablespaces;

Oracle trace files are detailed logs that provide a chronological record of all events that occur during a database operation. They can be used to troubleshoot performance issues, debug errors, and gain insights into the behavior of your database.

To check an Oracle trace file, you can use the TKPROF utility. TKPROF is a command-line tool that can be used to format and analyze trace files. To use TKPROF, you must first specify the trace file that you want to check. You can then use the TKPROF options to format the trace file in a variety of ways. For example, you can use the ‘-s’ option to sort the trace file by event, or the ‘-r’ option to reverse the order of the events.
