Oracle Database Objects and Naming rules

 

Oracle Database objects:

  1. Tables: Basic storage structures for data organized in rows and columns.
  2. Indexes: Improve the speed of data retrieval operations by providing quick access paths.
  3. Views: Virtual tables based on the result of a SELECT query, simplifying data access.
  4. Sequences: Objects used to generate unique numbers, often for creating primary key values.
  5. Synonyms: Aliases for database objects, providing alternative names for simplifying access.
  6. Stored Procedures: Sets of SQL statements stored for execution. They don’t return a value.
  7. Functions: Sets of SQL statements stored for execution, returning a value.
  8. Triggers: Sets of instructions executed automatically in response to specific events.
  9. Packages: Organize related procedures, functions, and PL/SQL constructs for modularization.
  10. Materialized Views: Views that store the result set physically, improving query performance.
  11. Constraints: Rules applied to tables to enforce data integrity, such as primary key and foreign key constraints.
  12. Partitions: Divide large tables and indexes into smaller, more manageable pieces.
  13. Database Links: Connections to remote databases, allowing communication between them.
  14. Roles: Named groups of privileges assigned to users, simplifying access control.
  15. Profiles: Set of resource limits and password policies for database users.
  16. Clusters: Physical storage structure that groups tables sharing common columns.
  17. Snapshots: Read-only copies of data from remote databases, updated periodically.
  18. LOBs (Large Objects): Data types for handling large amounts of data, like BLOBs (Binary LOBs) and CLOBs (Character LOBs).
  19. Directories: Logical aliases for physical file locations, used in database operations.

Oracle Object Naming Rules:

  1. Length: Keep names under 30 characters.
  2. Characters: Use letters, numbers, and underscores.
  3. Reserved Words: Avoid Oracle reserved words.
  4. Case: Stick to uppercase (default) unless using double quotes for case sensitivity.
  5. Special Characters: Use underscores instead of spaces or symbols.
  6. Global/Local Names: Ensure uniqueness within a schema.
  7. Quoted Identifiers: Use double quotes if needed, but be aware of case sensitivity.
  8. Prefixes/Suffixes: Consider using for clarity, e.g., “EMP_” for employee-related objects.

Example:

  • table_name
  • date_of_birth
  • firstname
  • "WELCOME & ALL!"

Oracle Database 19C Performance Tunning - PART 1

Advantages: 1. Improved Query Performance •    Optimized SQL execution plans lead to faster query response times. •    Reduces unnecessary full table scans and improves indexing strategies. •    Parallel execution tuning speeds up large data processing tasks. 2. Better Resource Utilization •    Efficient use of CPU, memory, disk I/O, and network resources. •    Reduces contention on Redo Logs, Undo Tablespaces, and Buffer Cache. •    Helps in load balancing across multiple instances in RAC (Real Application Clusters). 3. Increased System Scalability •    Ensures that the database can handle a growing number of users and transactions. •    Proper tuning allows scaling without degrading performance. •    Optimized parallel processing ensures better performance on multi-core servers. 4. Lower Infrastructure Costs •    Reduces the need for add...

Oracle RMAN Backup And Restore

RMAN: (Oracle 8) RMAN (Recovery Manager) is a utility provided by Oracle Database to perform backup, restore, and recovery operations. It is a command line tool. Features of RMAN in Oracle 19c Comprehensive Backup Capabilities: Full and incremental backups. Block-level backups for efficient data storage. Archived redo log backups. Fast Recovery Area (FRA) integration for centralized backup storage. Efficient Recovery Options: Point-in-time recovery (PITR). Complete and incomplete recovery. Flashback database capabilities for quick undo of changes. Multitenant Database Support: RMAN fully supports container databases (CDBs) and pluggable databases (PDBs). Provides flexibility to back up and recover individual PDBs or entire CDBs. Automatic Space Management: Manages disk space in the FRA. Automatically deletes obsolete backups and archived logs. Data Deduplication and Compression: Backup optimization through block-level deduplication. Built-in compression algorithms to reduce storage req...
