Inspection service

Supports inspection of clock source settings for OBServer nodes within the same cluster, preventing abnormal major compactions caused by inconsistent clock source settings.

Binlog management

• Supports setting the number of instance replicas when enabling the Binlog service. The Binlog service automatically distributes instance replicas based on the number of Binlog servers in the cluster.
• Supports adding new instance replicas for Binlog instances. A single business tenant can have a maximum of five instance replicas.
• Supports managing standby Binlog instances, including starting, stopping, throttling, restarting, deleting, and switchover operations.
• Supports deleting the primary Binlog instance.
• Prevents accidental operations on the MetaDB of the Binlog service, avoiding service disruptions.

Backup and restore

• Supports setting backup attributes for zones, regions, and IDCs, reducing cross-region network traffic in multi-region or multi-IDC deployment scenarios and improving backup speed.
• Supports setting zone priority to Random when restoring tenants.

Platform features

• AI Assistant: Provides intelligent Q&A services for OceanBase and its related products based on Large Language Models (LLMs), PowerRAG, and an integrated OceanBase knowledge base.
• O&M Management: Supports creating and downloading resource information reports for OceanBase clusters, tenants, OBProxy clusters, hosts, Binlog services, and arbitration services in the Report Center. Supports modifying the report retention period using the ocp.report.center.report.retention.days parameter.
• Parameter Templates: Supports importing and exporting parameter templates in YAML format for OceanBase clusters, tenants, OBProxy clusters, and Binlog services.
• Cluster Management > O&M Configuration: Adds five new collection metric switches to control whether to collect information such as wait event, cache hit rate, and partition count.

Feature enhancements

Cluster management

• Only clusters in the Stopped, Unavailable, Deprecated, or Migrated state can be directly deleted.
• In scenarios where units are to be migrated, you can precheck the CPU, memory, log disk, and data disk resources to avoid migration issues due to insufficient resources.
• You can enable or disable Cgroups without restarting the cluster. Supported OceanBase versions: [V4.2.5 BP2, V4.3.0) and [V4.3.5, +∞).

Tenant management

Feature changes

Clusters and hosts managed by the host management feature no longer support container-type hosts.

Key features

AI assistant (Experimental)

OceanBase AI assistant leverages large language models (LLMs) and PowerRAG, while integrating OceanBase's built-in knowledge base and native vector and full-text indexing capabilities, to create a core intelligent Q&A engine. Based on PowerRAG's multi-round retrieval mechanism, LLMs can accurately access technical documents, best practices, and failure cases from the knowledge base, providing systematic and specialized solutions for key database operations such as system configuration optimization, failure diagnostics, and performance bottleneck analysis.

For large model configuration, OCP allows users to flexibly integrate third-party large models such as Tongyi Qianwen, JiuLong, and DeepSeek, or deploy a self-built large model through the System Management > External Integration > AI Models module. Users can configure LLMs, embedding models, and optional reranking models to quickly activate AI assistant capabilities. Additionally, OCP supports importing enterprise-specific best practices and standard operating procedures (SOPs) to continuously expand the knowledge base's industry adaptability.

Secure Sockets Layer (SSL) encryption

In the era of accelerated digital transformation, data transmission security has become a core requirement. OBProxy and OceanBase support SSL encryption, establishing an encrypted communication channel at the transport layer to provide end-to-end protection for network connections, effectively mitigating risks of data theft and tampering, ensuring the confidentiality and integrity of communication processes, and reinforcing the security of data transmission from the ground up.

As the central hub for full-chain operations and maintenance, OCP provides comprehensive management capabilities for the entire certificate lifecycle:

• Convenient certificate operations: Supports one-click certificate upload and deletion, simplifying certificate management.
• Deep security configuration: Integrates SSL encryption configuration for OBProxy and OceanBase, supporting custom certificate update strategies to ensure the continuous validity of encrypted connections.
• Multi-format certificate support: Provides standard format certificates such as p7b/PEM/JKS for business application access, meeting diverse technical stack security requirements.

Through OCP's unified management, users can easily implement secure communication across business applications > OBProxy > OBServer nodes, as well as secure RPC communication between OBServer nodes, ensuring secure data transmission in key areas such as business access, proxy forwarding, and node interactions, building a comprehensive security barrier for stable database operation.

Bug fixes

OCP V4.3.6 mainly fixes the following issues:

• Fixed the issue where transaction data collection by OAS is incomplete when there are many concurrent transactions.
• Fixed the issue where OBServer replacement fails when an OBServer fails.
• Fixed the issue where disaster recovery switching cannot be immediately performed in multi-cluster mode.
• Optimized the issue of UI input box lag.
