Question

我的oracle数据库存在问题，我已经搜索/尝试加载以修复以下错误，但我无法将PLSExtProc的状态更改为READY：

 stream.foreachRDD { rdd =>
    rdd.foreachPartition { iter =>
    // make sure connection pool is set up on the executor before writing
    SetupJdbc(jdbcDriver, jdbcUrl, jdbcUser, jdbcPassword)

    iter.foreach { case (key, msg) =>
      DB.autoCommit { implicit session =>
        // the unique key for idempotency is just the text of the message itself, for example purposes
        sql"insert into idem_data(msg) values (${msg})".update.apply
      }
    }
  }
}

以下是一些可以提供帮助的信息：

这是完全正常和预期的。 listener.ora的SID_LIST部分中的每个条目都将显示为UNKNOWN状态。这只是意味着听众正在接受你的话，因为你列出了它。与那些显示READY状态的对比。这些来自数据库实例本身向监听器注册。把听众想象成酒店的前台服务员。 listener.ora的SID_LIST部分是夜班经理，将职员列入酒店客人名单。职员无法知道清单的准确性，所以状态是未知的。但是，如果一位客人走过来说“我的名字是鲍勃。如果有人要求我，我将在201室”，那就是数据库向听众注册。

实例＆＃34; PLSExtProc＆＃34;，状态未知
