mysql 事务只读: Could not retrieve transation read-only status server

 

现场日志:

Resolved [org.springframework.jdbc.UncategorizedSQLException:
### Error updating database. Cause: java.sql.SQLException: Multi-statement transaction required more than 'max_binlog_cache_size' bytes of storage; increase this mysqld variable and try again

 

java.sql.SQLException: Could not retrieve transation read-only status server

 

解决过程: 

       1. 查看mysql的事物隔离级别 SHOW VARIABLES LIKE '%iso%';

        返回结果: REPEATABLE-READ

        把这个改成:READ-COMMITTED 就好了: SET GLOBAL tx_isolation='READ-COMMITTED'; 

      (记得java重启应用,要永久生效的就改my.ini配置文件)

操作后无效

     2.  将max_binlog_cache_size  原来的8M 调到512M   解决
