Oracle 23c AI RMAN New Features....

 Oracle 23c AI (also known as Oracle Database 23c: The Long-Term Release) introduces several cutting-edge features, enhancements, and optimizations to RMAN (Recovery Manager), ensuring even more robust backup and recovery capabilities. RMAN remains an essential tool for Oracle DBAs, and with 23c, it becomes even more powerful, particularly with AI-assisted capabilities. Below are 10 new features in RMAN in Oracle 23c:

1. AI-Assisted Backup and Recovery Optimization

  • Feature Overview: Oracle 23c introduces AI-driven algorithms that analyze system workload patterns, storage usage, and historical backup performance to optimize backup windows, schedules, and methods. The AI assistant learns from past recovery operations to suggest optimal backup strategies.
  • Benefit: More efficient backups with minimal impact on production, and faster, more predictable recovery times based on learned behavior.

2. Automatic Block Repair with AI

  • Feature Overview: This feature enhances RMAN’s block media recovery by using AI algorithms to predict and identify corruption patterns. When corrupt blocks are detected, RMAN automatically initiates a repair using AI-based predictions on where data might have been impacted.
  • Benefit: Minimizes downtime and allows proactive identification and repair of corrupt blocks before they impact business operations.

3. Intelligent Recovery Plan Suggestions

  • Feature Overview: RMAN in Oracle 23c can now offer intelligent suggestions for recovery plans. AI algorithms analyze the severity of data loss or corruption and suggest the most efficient recovery plan, considering the available backups, logs, and business priorities.
  • Benefit: Streamlines the decision-making process during recovery scenarios, saving DBAs time and reducing stress during critical recovery operations.

4. AI-Powered Compression for Backups

  • Feature Overview: RMAN's compression algorithms in Oracle 23c use AI techniques to dynamically adjust compression levels based on data types and workload. The AI monitors the data characteristics, storage performance, and CPU utilization to balance compression efficiency.
  • Benefit: Improved storage efficiency and reduced backup size without sacrificing performance or increasing resource usage unnecessarily.

5. Automated Data Tiering for Backup Storage

  • Feature Overview: Oracle 23c enhances RMAN with the ability to automatically tier backup data between different storage types (e.g., SSDs, HDDs, cloud object storage). RMAN uses AI-based rules to move less-frequently accessed backup data to slower, more cost-effective storage tiers.
  • Benefit: Reduces storage costs while ensuring frequently used backups remain accessible on high-performance storage.

6. Enhanced Integration with Oracle Cloud Storage (OCI)

  • Feature Overview: RMAN now offers deeper integration with Oracle Cloud Infrastructure (OCI), allowing easier management of backups to Oracle Cloud. The integration includes AI-based recommendations on which backups should be moved to the cloud and when.
  • Benefit: Simplifies cloud backup management and helps DBAs make cost-effective decisions regarding storage usage and data protection in OCI.

7. Real-Time Analytics for Backup Performance

  • Feature Overview: RMAN now incorporates real-time analytics that track and display detailed metrics for backup performance, such as throughput, compression ratios, and recovery time objectives (RTOs). The AI engine analyzes this data to recommend performance improvements.
  • Benefit: Provides greater visibility into backup operations and suggests actionable improvements, helping DBAs fine-tune their backup strategy.

8. Snapshot-Based Backup Integration

  • Feature Overview: RMAN in Oracle 23c supports integration with storage-level snapshots for databases stored on compatible storage systems. This includes managing and tracking these snapshots alongside RMAN backups.
  • Benefit: Enables faster, more frequent backups with near-instantaneous snapshot creation, while RMAN keeps track of all backup metadata for easy recovery.

9. Advanced Cloning Capabilities with AI Optimization

  • Feature Overview: RMAN in Oracle 23c improves the duplicate/cloning process by leveraging AI to optimize clone creation based on workload, storage type, and available resources. The AI engine decides the best approach for cloning databases, considering factors like performance impact and network bandwidth.
  • Benefit: Cloning databases is faster and more efficient, particularly in cloud and hybrid environments, where resources can fluctuate.

10. Unified Backup Catalog Across Multitenant Environments

  • Feature Overview: Oracle 23c enhances RMAN's cataloging and management of backups in multitenant environments (CDBs and PDBs) by unifying the catalog for easy management across all pluggable databases. AI-assisted reporting helps track backup status and recovery points across the container database (CDB) and its PDBs.
  • Benefit: Simplifies backup management in complex multitenant environments, ensuring that all pluggable databases are protected with the same level of visibility and control.

Summary of Benefits:

  • AI-Driven Automation: AI improves RMAN’s decision-making, automating many tasks such as backup optimization, corruption detection, and recovery plan creation.
  • Storage Optimization: Features like AI compression and data tiering reduce storage costs and make better use of available resources.
  • Cloud Readiness: Enhanced integration with Oracle Cloud (OCI) makes cloud backups seamless, scalable, and cost-effective.
  • Real-Time Monitoring: Advanced analytics and real-time performance metrics help DBAs monitor and improve backup efficiency.

With these features, RMAN in Oracle 23c empowers DBAs to manage backups more efficiently while leveraging AI to reduce complexity, optimize performance, and enhance disaster recovery capabilities.

How to Configure Logging for EM 12c Management Agent

The goal of this article is to provide instruction on how to enable logging for the Enterprise Manager 12c Management Agent.. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The logging properties for the agent are stored in $EMSTATE/sysman/config/emd.properties file, same as in 11.1. But the properties that control logging follow the log4j configuration syntax instead of the syntax supported by the 11.1 agent. To active changes to the logging parameters, you can use either of the emctl commands: emctl reload agent emctl setproperty agent Overview Agent logging entries look similar to the standard log4j logging, with the only significant difference being the prefix 'Logger.' that you will see on each line. For example: # logging properties Logger.log4j.appender.Rolling=org.apache.log4j.RollingFileAppender Logger.lo
