CUBRID 11.3 has been released.

Connectivity : Improved connectivity by improving database links

Performance Enhancement : Improved performance by improving query optimizer and aggregation functions

Convenience Enhancement : Improved management convenience through utility improvements

1. Improvement and Fix

* Database Link

  - Provides table extension format (object@server) for remote objects for user convenience

  - Provides the ability to Insert, Update, and Delete as well as query data for remote objects

  - Additional support for heterogeneous DBMS: MariaDB

* Improvements in Performance

  - Improved query optimization, including predicate pushdown, view transformations, and removing unnecessary Join tables

  - Improved performance by improving aggregation functions (MIN, MAX GROUP_CONCAT)

  - Improved performance issues caused by skewed indexes by providing a Deduplication option when creating an Index (or Foreign key)

* Improvements in Manageability

  - Provides an alternative if /etc/hosts is not available for security reasons ($CUBRID/conf/cubrid_hosts.conf)

  - Provides Vacuumdb with the ability to display information on which indexes OVFP reads occurred while performing an index VACUUM

  - Provides new commands to the CSQL utility

      * Connect : Commands to switch to another user (including another DB) while in use

      * Edit [format|fmt] : Commands to auto-edit SQL with a set formatter

      * Formatter_cmd : Commands to register a formatter

      * Singleline : Commands to set line-by-line execution for incoming queries

  - Provides the Unloaddb utility an option to unload separated by object (--split-schema-files)

  - Provides the Loaddb utility with the option to load files separated by objects at once (--schema-file-list)

* Compatibility

  - Provides compatibility of numeric operations and output through the setting, oracle_compat_number_behavior

* HA

  - Provide an alternative method when ping command is not available in HA environment (See configuration value ha_tcp_ping_hosts)

  - Improved SQL logging behavior in HA environment

  - Fixed intermittent replication error when entering data using Loaddb -C in HA environment

* Feature enhancements and Bug fixes

For more details, please refer to the CUBRID 11.3 change logs(https://github.com/CUBRID/cubrid/releases/tag/v11.3) and online manuals (https://www.cubrid.org/manual/ko/11.3/release_note/index.html)

2. Precautions

  - Query optimizer statistics are not automatically updated when DDL statements are executed, and users must manually run the UPDATE STATISTICS statement to update the statistics

  - When changing the type of a column with the AUTO_INCREMENT attribute or a column with the default value in the ALTER TABLE statement, an error occurred when changing the AUTO_INCREMENT attribute to an unavailable type or changing the existing default value to an unconvertible type

  - Unable to get Connection object via cubrid.jdbc.driver.CUBRIDDriver.getDefaultConnection() in server-side JDBC. 

Instead, DriverManager.getConnection("jdbc:default:connection:"); should be used

  - If you specify an invalid index name or a table name in the USE INDEX syntax, it will be ignored without raising an error (if you want to write it to the log file, you can set the error_log_warning setting to yes)

  - When creating a CREATE INDEX, the position of the COMMENT clause is changed to the last position of the syntax after the WITH clause or INVISIBLE clause

  - The driver version compatible with CUBRID 11.3 is 11.2

3. Environmental Requirements

  - Linux: 64bit, kernel 2.4 or higher, Windows: Windows7 or higher (Windows 7 requires the latest security updates)

  - JRE 1.8 or higher is required when using JSP or CUBRID Admin/CUBRID Manager
