Version information

• Release date: October 18, 2022

• Version: V2.4.0

Overview

OceanBase Connector/J V2.4.0 introduces support for the OB2.0 protocol and provides end-to-end tracing capabilities in collaboration with OceanBase Database and ODP. This version is recommended for regular business use and is suggested to be used with OceanBase Database V4.0.0.

Feature enhancements

• Added support for the OB2.0 protocol, controlled by the useOceanBaseProtocolV20 parameter, which is enabled by default.

• Added support for end-to-end tracing in collaboration with OceanBase Database and ODP, controlled by the enableFullLinkTrace parameter, which is disabled by default. When enableFullLinkTrace is set to true, useOceanBaseProtocolV20 will also be forcibly changed to true.

Bug fixes

• Fixed an issue where LoadBalance in daemon thread mode would report the No active connection found for master exception during network fluctuations.

• Fixed an issue where the Server returned an exception due to the ArrayBinding setNull API.

• Fixed an issue under the PS combined protocol (useServerPrepStmts=true&useOraclePrepareExecute=true) where Procedures were called in a loop, but only the first one closed the PS.
