执行utplsql-cli命令时，我已经成功连接到数据库并且执行了所有测试。不幸的是，当之前执行任何sqlplus命令时，utplsql-cli会抛出错误：

当我在 utplsql-cli 工具中将 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
你知道怎么解决吗？我正在考虑由 sqlplus 命令创建的长寿命会话，但我已经使用 V$SESSION 视图验证了这一点。所有连接均已关闭。
提前感谢，普热梅克
HikariCP 在 3.1.7 版本中被完全删除(请参阅拉取请求和相关问题(。这也应该可以解决此问题。
