Oracle Backup & Recovery: Ensuring Data Integrity & AvailabilityApr 10, 2025 am 09:40 AMThe core purpose of Oracle backup and recovery is to quickly restore the database to a consistent state when data is lost or corrupted. 1. Backup phase: Copy the database file to the backup media through RMAN or other tools. 2. Recovery phase: When a database fails, first restore the backup data, and then restore to the pre-failed state by applying the redo log file.
Oracle Real Application Clusters (RAC): Scalability & High AvailabilityApr 09, 2025 am 12:16 AMOracleRAC achieves high availability and scalability through multi-node shared database storage. Its working principle includes load balancing, failover and dynamic node expansion to ensure efficient operation of the system and data consistency.
Oracle Cloud Infrastructure (OCI): Deploying & Managing Oracle Databases in the CloudApr 08, 2025 am 12:09 AMDeploying and managing Oracle databases in OCI can be achieved through the following steps: 1. Create a database instance and set configuration parameters using OCIPythonSDK; 2. Configure network and storage resources; 3. Connect to the database and execute SQL queries; 4. Perform database backup and recovery operations; 5. Optimize database performance by adjusting resource configuration, network optimization and backup policies. This is a highly automated process where users only need to provide the necessary configuration parameters and the OCI will handle the remaining work.

Understand the Oracle database schema, including the relationship between instances and databases. 2. Master performance tuning methods, such as SQL tuning and index optimization. 3. Familiar with backup and recovery strategies and use RMAN and data pump tools. Through these preparations, you can demonstrate your professional skills in the interview and successfully pass the interview.
Advanced Oracle SQL Tuning: Optimizing Query Performance for ExpertsApr 06, 2025 am 12:06 AMOracleSQL tuning can improve query performance through the following steps: 1. Create an appropriate index, such as creating an index for the department column; 2. Analyze the execution plan, use the EXPLAINPLAN command to view and optimize; 3. Perform SQL rewrite, such as using subqueries to avoid unnecessary connection operations. Through these methods, the query efficiency of Oracle database can be significantly improved.
Oracle Database Security: Hardening & Protecting Your DataApr 05, 2025 am 12:17 AMThe security of Oracle databases can be achieved through a variety of measures, including authentication, authorization, encryption and auditing. 1) Use password files for user authentication and authorization; 2) Protect sensitive data through transparent data encryption (TDE); 3) Use virtual private databases (VPDs) to achieve fine-grained access control; these methods ensure the confidentiality, integrity and availability of data.
Oracle GoldenGate: Real-Time Data Replication & IntegrationApr 04, 2025 am 12:12 AMOracleGoldenGate enables real-time data replication and integration by capturing the transaction logs of the source database and applying changes to the target database. 1) Capture changes: Read the transaction log of the source database and convert it to a Trail file. 2) Transmission changes: Transmission to the target system over the network, and transmission is managed using a data pump process. 3) Application changes: On the target system, the copy process reads the Trail file and applies changes to ensure data consistency.
