Oracleリスナーとデータベース・サービスが実行されない理由

Question

私は、Red Hat Linux 7.2とOracle 12cで足元を濡らし始めています。先週末、RHEL 7.2でOracle 12cをサポートできるかどうか試してみました。結局のところ、私はRHEL 7.2 VM上でOracleを立ち上げることができましたが、問題はありませんでした。しかし、私は を一度に1つずつ解決しました。私はVMを吹き飛ばし、最初からすべてを開始しました。

今私は&を実行するかなり良いセットアップがあると思います。私が理解できない唯一のことは、Linuxボックスを再起動するときです.Oracle listnerとデータベースサービスは、Windows Server 2012 R2システムと同様に自動的に起動しません。これらのサービスが実行されていない場合、当然私は をOracle DBに接続できません。リスナーが何のサービス をサポートしていません：ファイル名を指定して実行

を開始LSNRCTL

私のようなメッセージに何かが表示されますoracleユーザーとして

1. ログオン：それを修正するために、私はこれらの2つのコマンドを実行する必要がありますこれは問題ありません。その後

接続データベースへ

と

SQLを実行>スタートアップが、すべてが通常通り実行されています。どのOracleクライアントからでもOracleデータベースに接続できます。私の質問は次のとおりです：これはLinuxボックスでの通常の動作ですか？ Oracleのインストール中に何かが見逃されましたか？これらのサービスが自動的に開始されるはずですが、これを修正するには何が必要ですか？

ありがとうございます。

Answer 1

詳細については、リスナーログを確認する必要があります。

検索リスナーのログの場所：

$ lsnrctl stat 

LSNRCTL for Linux: Version . . . 
. . . 
Listener Log File  /home/app/oracle/product/10.2/network/log/listener.log 

Answer 2

このエラーソリューションは、まず、このエラーが発生する理由のは理解してみましょう、非常に簡単です。 ）ホスト名/ IPアドレスがある、それはパラメータが

-ORACLE_SID in oracle environment. 
-SID_NAME in tnsnames.ora file. 
-SERVICE_NAME in listener.ora file. 

2値の下にチェックし、どこでも同じである必要がありますあなたのデータベースおよびサービス名が正しくOracle環境に設定されていない

1）：それは基本的に二つの理由があります紛失、間違い、綴り間違いなどがありますので、下記をご確認ください。

-Check the IP ADDRESS in /etc/hosts file. 
-It should be same in listener.ora and tnsnames.ora file 
-And it should be able to ping from the local and remote server. 

今私も同じ問題に直面し、解決した参照：
