使用 DBCA 創建數據庫時出錯

我在 Elementary OS 5.0 上使用 Oracle Database 12c R2。安裝完成，沒有任何錯誤。然後我創建了監聽器，它開始就好了。 當我使用 dbca 創建數據庫時，它顯示警告

ORA-12547: TNS: 失去聯繫

（當我執行 tnsping 127.0.0.1 它返回 OK (0 ms) ）點擊忽略後，它顯示此錯誤

dbca 關閉了。我還是 Oracle DB 的新手並且是自學成才的，那麼我該如何解決這個問題？

不支持基本作業系統，找到支持的作業系統。

我建議直接使用虛擬機而不是您的機器，這應該有助於嘗試不同的配置，這些配置可能無法直接從您的機器上進行。

對於失去的聯繫，請檢查 Listener 中配置的主機名。

然後，您可以檢查該主機名解析到哪個 IP。

對於試用版，只需修改您的主機文件並將 localhost、系統名稱和 FQDN 映射到 127.0.0.1。
