当执行utplsql-cli命令时，我已成功连接到数据库，并且所有测试均已执行。不幸的是，当之前执行任何sqlplus命令时，utplsql-cli会引发错误：

当我将utplsql-cli工具中的maxLifeTime参数更改为'0'时，
HikariPool-1 - Exception during pool initialization.
11:12:44 java.sql.SQLRecoverableException: IO Error: The Network Adapter could not establish the connection
您知道如何解决该问题吗？我在考虑sqlplus命令进行的长期会话，但是我已经使用V $ SESSION视图进行了验证。所有连接均已关闭。
预先感谢， 普热梅克
