Effortless Database Maintenance with Oracle Fleet Patching and Provisioning

 Oracle Fleet Patching and Provisioning (FPP), previously known as Rapid Home Provisioning (RHP), is a powerful feature introduced in Oracle 19c designed to streamline and automate the software lifecycle management process. FPP simplifies the mass deployment, patching, and upgrading of Oracle software, offering a centralized approach to managing Oracle Homes, databases, and clusters. Whether you're handling Oracle Grid Infrastructure (GI) or databases from version 11g onwards, FPP provides the tools to efficiently manage these environments.

Core Features of Oracle FPP

• Zero-Downtime Oracle GI Patching: For RAC databases with two or more nodes, FPP allows patching to be performed with zero downtime, ensuring continuous availability during maintenance operations.

• Automated PDB Relocation: This feature optimizes patching by enabling individual Pluggable Databases (PDBs) to be relocated and patched more efficiently, reducing the overall impact on the system.

• Support for Oracle Restart: Starting with Oracle 19c, FPP facilitates patching and upgrading operations for Oracle Restart configurations, enhancing its versatility across different Oracle setups.

• Direct Transfer Method: From version 19c onwards, FPP eliminates the need for temporary NFS mount points for software home transfers, making the process more straightforward and reducing setup complexity.

• Local Mode Automation: Introduced in Oracle 18c, FPP enables the automation of database and GI home updates in a local mode, removing the necessity for an FPP server or client within the architecture.

• Zero-Downtime Upgrades: By automating the entire upgrade process, FPP minimizes the effort, risk, and application downtime traditionally associated with database upgrades.

Modes of Operation

Oracle FPP operates in two primary modes:

• Central Server Mode: In this mode, the FPP server acts as a central repository for "gold images"—standardized and tested versions of Oracle software. These images can be deployed across multiple nodes in a data center to create new clusters and databases, or to patch, upgrade, and scale existing installations.

• FPP Client Mode: Built into Oracle GI (12c and later), FPP clients can retrieve and apply gold images from the FPP server. This mode supports the automated application of maintenance operations, ensuring that each client remains consistent with the centrally managed standards.

Comprehensive Provisioning Capabilities

Oracle FPP supports the provisioning of Oracle Database Homes for versions 11g and later. After provisioning, a single FPP command can initiate the creation of various database configurations:

Oracle RAC One Node or multi-node clusters

• Single instance databases with or without GI or Oracle Restart
• Multitenant container databases
• Admin or policy-managed databases

Patching and Upgrade Strategies

FPP promotes "out-of-place" patching as the best practice. This method involves creating a patched environment in a new directory, allowing the database home to be seamlessly switched to the updated version. In the event of any issues post-upgrade, rollback is simple since the old home remains intact and available.

Conclusion

Oracle Fleet Patching and Provisioning is an essential tool for any organization looking to simplify and automate the management of Oracle database environments. With features like zero-downtime patching, automated PDB relocation, and direct transfer methods, FPP significantly reduces the operational overhead and risks associated with database maintenance. Whether you're managing a single database or an entire fleet, FPP ensures your Oracle infrastructure remains secure, up-to-date, and highly available.

Oracle Autonomous Database: Streamline Your Performance with Automatic Indexing

 In the ever-evolving landscape of database management, Oracle's Autonomous Database stands out for its advanced automation capabilities. One of its standout features is Automatic Indexing, which streamlines index management, a traditionally complex and manual task. Here’s an in-depth look at how Automatic Indexing works and how you can harness its power.

What is Automatic Indexing?

Automatic Indexing is designed to automate the creation, maintenance, and management of database indexes. This feature is particularly valuable for optimizing performance without the need for manual intervention. Although Automatic Indexing is disabled by default, once activated, Oracle Autonomous Database continuously monitors your application workload, creating and managing indexes as needed to enhance query performance.

Enabling Automatic Indexing

To enable Automatic Indexing, you’ll use the DBMS_AUTO_INDEX.CONFIGURE procedure. This simple command sets up the system to create and manage indexes automatically:

EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','IMPLEMENT');

When Automatic Indexing is enabled, any new indexes created are visible, allowing them to be used in SQL statements. Additionally, index compression for these auto-generated indexes is enabled by default, optimizing storage and performance.

Disabling Automatic Indexing

If you need to disable Automatic Indexing, you can do so with the following command:

EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','OFF');

This command halts the creation of new auto indexes, but any existing indexes remain in place and operational.

Considerations and Restrictions

While Automatic Indexing offers significant benefits, there are some restrictions to be aware of:

• SODA Compatibility: Automatic Indexing does not support SQL/PL/SQL code that uses the SQL/JSON function json_exists.

• Query-by-Example (QBE): Automatic Indexing is also not supported for SODA query-by-example operations.

These constraints are essential to consider when planning your database indexing strategy, particularly if your applications rely on these specific features.

Benefits of Automatic Indexing

• Efficiency: Automates index management, reducing the need for manual intervention and freeing up administrative time.

• Performance: Continuously adapts to workload changes, ensuring that indexes are optimized for current query patterns.

• Cost-Effective: Reduces administrative overhead and minimizes the risk of performance bottlenecks due to manual index management.

In summary, Oracle’s Automatic Indexing in the Autonomous Database is a powerful tool that simplifies index management, enhances performance, and ensures that your database operates at peak efficiency with minimal manual intervention.
