V4.1.0 BP2

Version information

  • Release date: June 28, 2023

  • Version: V4.1.0 BP2

  • RPM version: obproxy-4.1.0.0-20230628180544

Bug fixes

  • Fixed the issue of session information synchronization and the issue that the nodes to which the DELETE and UPDATE statements are routed are taken as coordinators during an upgrade.

  • Fixed the issue of session information synchronization in the case of error packets.

  • Fixed the issue where internal SQL statements are not routed based on the specified IP addresses.

  • Fixed the issue where disconnection occurs when an SQL statement is executed after xa_start hold.

  • Fixed the issue that the parsing module of ODP may cause memory leaks.

  • Fixed the issue where ODP is disconnected and does not try to connect to the IP addresses of other OBServer nodes if an invalid IP address 0.0.0.0:0 is specified for the target_db_server+IP address mode when both the mock and target_db_server+IP address routing modes are supported.

  • Fixed the issue that in IP address-based routing at the global level, if the first IP address belongs to a log replica, ODP does not retry to connect to an available IP address when a core dump occurs.

  • Fixed the issue that if the specified IP address belongs to ODP in IP address-based routing, the client is hung due to cyclical forwarding by ODP.

  • Fixed the issue that disconnection occurs when the specified IP address is 127.0.0.1 in IP address-based routing.

  • Fixed the issue where connection establishment fails if only last_insert_id is modified.

  • Fixed the issue where performance jitter occurs in business SQL statements when CPU resources are exhausted due to configuration changes.
