Before you begin working on the Oracle database, you must comprehend all of the key terms covered in this section. Nearly all of the terminology and parameters that are regularly used in Oracle databases are covered in this section.
This is often known as Random-Access Memory (RAM), is a type of memory that is used by several applications at once. In Oracle Database Administration, there are two different kinds of memory management strategies. These two shared memory types are
- Manual Memory Control
- AUTOMATION OF MEMORY
Infrastructure for System Support: This consists of both foreground and background operations that make it easier for applications to communicate with databases. Once an Oracle instance is started, one system support procedure immediately begins. In controlling the connection between an application and the data, each step is crucial.
Operating System Files: These are a group of files that each have a crucial function as soon as the database starts up.
For instance: The background process for retrieving data from the database can be considered as this crucial component of memory structure.
Process: In the administration of an Oracle database, a process is a running instance that may also be referred to as a job or task. These can either be classified as Oracle Processes or User Processes.
Buffer Cache: This is a little repository for customized or frequently used data. This cache is well-liked for enhancing memory’s overall performance, and it connects to the database for quick access.
Shared pool: Data that must be shared with the users is contained.
Massive Pool: As its name implies, this is the best location to keep large processes with reliable features like backups and data recovery.
Redo Log Buffer: This is a backup repository that holds the modified data and aids in instances or processes being recovered. This crucial element of the Oracle database 12C architecture performs fantastically in the event of a system loss.
Locks: Locks are necessary to limit the simultaneous
