OAT V4.3.2

Overview

This version enhances the user experience in operating OceanBase products by fully supporting IPv6 networks and officially supporting Ubuntu V22.04 and V24.04, thereby enabling users to build a more flexible and reliable O&M system.

Release highlights

• Release date: 2025.06.06

• Previous version: V4.3.1

• Version: V4.3.2

New features

• This version achieves full support for IPv6, covering: host initialization; deployment with MetaDB (OceanBase 4.3.5-BP2) and OCP clusters using IPv6 addresses; and OAT deployment on hosts with IPv6 addresses, providing solid support for building a fully IPv6-compatible system environment.

• 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 during server initialization

• Changed container reconstruction to an asynchronous task, supporting image copying and loading for container reconstruction

• Added system parameters:

  • oat.server.ignore_deps: specifies the installation dependency tasks to be skipped for the initialization server

  • oat.product.backup_meta_timeout: controls the timeout for the backup product metadata SQL

  • oat.server.warning_when_intel_numa_off: controls the NUMA check for Intel CPUs

Bug fixes

• Fixed the issue where /etc/rc.local fails to execute when an Ubuntu 22.04 server is added.

• Fixed the issue where an error occurs during the precheck step when an Ubuntu 22.04.3 server is added in OAT V4.3.1.

• Fixed the issue of remote file write errors.

• Fixed the incorrect settings and judgments for ip_local_port_range and ip_forward in OAT V4.3.1.

• Fixed the issue where the logic for setting vm.min_free_kbytes is inconsistent with the logic for checking this parameter during precheck, causing precheck to fail.

• Fixed the issue where the backup task fails when upgrading OCP with Meta and Monitor using different clusters.

• Fixed the error: Unknown column 'is_default_cm' in 'where clause' when refreshing data for OMS.

• Added a check to verify the existence of the target container for installation or resource changes of a product/component/tool, ensuring the task is only added if the container exists.

• Added backend complexity verification for the initial OAT password.

Considerations

OAT 4.x versions support in-place upgrade from OAT 3.2.0 or later. Users can use the "Takeover Component" and "Takeover Product" features to upgrade from OAT of earlier versions or Antman deployments.
