What's New

This topic describes the features of OceanBase Admin Toolkit (OAT) V4.3.2.

New features

• This version implements full IPv6 support, covering: host initialization; deploying MetaDB with an IPv6 address (OceanBase Database V4.3.5-BP2) and OCP clusters; and deploying OAT on a host with an IPv6 address. These features provide a solid foundation for building a system environment compatible with the entire IPv6 protocol stack.
• Full adaptation to Ubuntu V22.04 and V24.04
• Adaptation to OMS V4.3.5 and OCP V4.3.6
• Added kernel boot parameter check for hosts during initialization
• Changed container rebuilding to an asynchronous task, supporting image copying/loading and container rebuilding
• Added system parameters:
  • oat.server.ignore_deps: specifies the installation dependency tasks to skip on the initialization server
  • oat.product.backup_meta_timeout: controls the timeout period for backing up product metadata SQL
  • oat.server.warning_when_intel_numa_off: controls the check for NUMA support in Intel CPUs

Optimized features

• Optimization of Product/Component Resource Change Logic:

  • Resource change tasks only copy and load images on servers with newly added nodes.
  • In scenarios where only container resource specifications change, the implementation method shifts from rebuilding the container to using Docker Update and Docker Restart.
  • Only allow the initiation of container rebuild tasks for containers that have stopped running. The container rebuild feature is now implemented through asynchronous tasks, and you can view the task progress and logs in the task center.

• Optimization of Server Initialization:

  • Supports Ubuntu V22.04 and V24.04 versions.

  • Supports the server restart feature. When the user initiates a server initialization task and enables the "Restart Server" feature switch, the system will automatically perform a restart if the kernel startup parameters are modified and require a restart for the modifications to take effect.
