ERROR [Thread-59] 2021-12-09 15:45:22 (AcquireAsyncJobsDueRunnable.java:85) exception during async job acquisition: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: Transactions not supported
`
原因：
数据库导入时，没有设置日志模式，所以不支持事务
解决方案：
执行如下命令
修改为unbuffer日志模式
ontape -s -L 0 -t /dev/null -U 数据库名
[gbasedbt@localhost bin]$ ontape -s -L 0 -t /dev/null -U test
Your evaluation license will expire on 2022-06-04 00:00:00
Archive to tape device '/dev/null' is complete.
