OceanBase Connector/J V2.4.3

Version information

• Release date: April 06, 2023

• Version: V2.4.3

Overview

OceanBase Connector/J V2.4.3 supports the Show Trace feature based on the Full-link Trace feature and supports the parsing of LOB Locator v2. We recommend that you use this version for general business.

Enhanced features

• The Show Trace feature based on the Full-link Trace feature is provided. You can run the Show Trace command to obtain the full-link tracing record of the last task in the session. For more information, see Show Trace.
• Parsing of LOB Locator v2 is supported in Oracle mode to adapt to the LOB optimization of the database kernel.
• The following three XA transaction-related flags are supported: ORATMSERIALIZABLE, ORATRANSLOOSE, and ORATMREADONLY, to enhance the compatibility with Oracle. For more information, see XA components.

Fixed issues

• In Oracle mode, the setCharacterStream and setClob APIs cannot distinguish between empty strings and empty LOBs, so that the query results are inconsistent with those in the Oracle database.
• When the JDBC LoadBalance feature is enabled, network issues cause data inconsistencies.
• When the JDBC LoadBalance feature is enabled, and the OBLB_STRATEGY parameter is not specified for a load balancing group, the global OBLB_STRATEGY setting does not take effect for the group either.
