OceanBase Database V3.1.1 is a beta version. It is used for proof of concept (POC) in internal and external projects.

Enhanced features

• The synchronous write logic of clog files is optimized. The use of shared memory is disabled. The reliability of log data in case of database faults is improved.

• The queue size of the gv$sql_audit view is optimized to support the caching of 10 million records.

• The values of the execute_time and get_plan_time fields in the gv$sql_audit view are optimized.

• The ASIN() and ACOS() functions are supported in MySQL-compatible mode.

Fixed issues

• Garbled characters are generated at the client during the conversion of character sets of the LOB type columns when row records are returned.

• If the EXISTS subquery contains NULL or COUNT(*), the result set is incorrect.

• The SQL execution plan fails to hit the plan cache because of the sensitive matching of sorting rules.

• The execution of the SHOW VARIABLES LIKE '%%' statement takes a large portion of time.

• The 4179 error is returned when the upgrade_checker script is executed during the upgrade of both primary and standby clusters.
