What are the types of oracle databases?
Oracle database types offer different capabilities including: Multi-Mode (MM), RAC, NoSQL, Autonomous Database, Exadata, Appliance, and Vault. Choosing the appropriate type depends on application and workload requirements, including data type, batch size, scalability, performance, and cost.
Oracle database types
Introduction
Oracle database provides many database types to meet the needs of different applications and workloads. These types mainly include:
Multi-Mode (MM)
- Standard Oracle database types that provide a wide range of functionality and flexibility.
- Suitable for most applications, including transaction processing, data warehousing and analytics.
Real Application Clusters (RAC)
- A group of fault-tolerant servers sharing the same database.
- Provides high availability, scalability and performance.
Oracle NoSQL Database
- A schema-less database based on key-value storage.
- Designed for handling large amounts of unstructured data.
Oracle Autonomous Database
- A fully managed cloud database service.
- Automatically handle management, maintenance and tuning tasks.
Oracle Exadata Database Machine
- A highly optimized integrated server and storage system.
- Designed for handling data warehousing and analytical workloads.
Oracle Database Appliance
- A preconfigured database server and storage device.
- Optimized for specific workloads, such as business intelligence and data warehousing.
Oracle Database Vault
- A secure database used to protect sensitive data from insider threats.
- Provides fine-grained access control and auditing.
Specific differences
- Function: MM provides the most comprehensive functions, while NoSQL is suitable for unstructured data processing .
- Availability: RAC provides the highest level of availability, while other types provide varying levels of redundancy.
- Scalability: RAC and Exadata are highly scalable, while other types may be limited.
- Performance: Exadata is optimized for specific workloads, while other types provide more general performance.
- Cost: Autonomous Database is a managed service, while other types require deployment and maintenance costs.
Choose a database type
Choosing the appropriate database type depends on the specific requirements of your application and workload. Consider the following factors:
- Data types and batching
- Availability requirements
- Scalability requirements
- Performance requirements
- Cost Budget

To query the Oracle tablespace size, follow the following steps: Determine the tablespace name by running the query: SELECT tablespace_name FROM dba_tablespaces; Query the tablespace size by running the query: SELECT sum(bytes) AS total_size, sum(bytes_free) AS available_space, sum(bytes) - sum(bytes_free) AS used_space FROM dba_data_files WHERE tablespace_

Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.

Uninstall method for Oracle installation failure: Close Oracle service, delete Oracle program files and registry keys, uninstall Oracle environment variables, and restart the computer. If the uninstall fails, you can uninstall manually using the Oracle Universal Uninstall Tool.

There are three ways to view instance names in Oracle: use the "sqlplus" and "select instance_name from v$instance;" commands on the command line. Use the "show instance_name;" command in SQL*Plus. Check environment variables (ORACLE_SID on Linux) through the operating system's Task Manager, Oracle Enterprise Manager, or through the operating system.

An AWR report is a report that displays database performance and activity snapshots. The interpretation steps include: identifying the date and time of the activity snapshot. View an overview of activities and resource consumption. Analyze session activities to find session types, resource consumption, and waiting events. Find potential performance bottlenecks such as slow SQL statements, resource contention, and I/O issues. View waiting events, identify and resolve them for performance. Analyze latch and memory usage patterns to identify memory issues that are causing performance issues.

SQL statements can be created and executed based on runtime input by using Oracle's dynamic SQL. The steps include: preparing an empty string variable to store dynamically generated SQL statements. Use the EXECUTE IMMEDIATE or PREPARE statement to compile and execute dynamic SQL statements. Use bind variable to pass user input or other dynamic values to dynamic SQL. Use EXECUTE IMMEDIATE or EXECUTE to execute dynamic SQL statements.

Triggers in Oracle are stored procedures used to automatically perform operations after a specific event (insert, update, or delete). They are used in a variety of scenarios, including data verification, auditing, and data maintenance. When creating a trigger, you need to specify the trigger name, association table, trigger event, and trigger time. There are two types of triggers: the BEFORE trigger is fired before the operation, and the AFTER trigger is fired after the operation. For example, the BEFORE INSERT trigger ensures that the age column of the inserted row is not negative.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.
