OracleデータベースのSID、サービス名、ポートを取得する方法は？

Question

アドレスxx.xx.xx.xxでOracleデータベースを実行しています。ログイン、パスワード、および初期カタログを知っています。

このデータベースにアクセスして確認できるように、Oracle SQL Developerで新しい接続を設定しようとしています。そのためには、SIDまたはサービス名を知る必要があります。

昔は、TNSPing.exeを実行してサービス名を取得していましたが、このプログラムはもう利用できません。 Oracleは配布していません。

この情報にどこかにアクセスする方法はありますか？

ありがとう

サーバーにアクセスできる場合は、リスナーが実行しているプロセスの数、リスナーがリッスンしているIPアドレスとポートを確認できます。 Linuxの例。

[Oracle@krw-ssps-db-02 ~]$ ps -ef|grep tnslsnr Oracle 6090 1 0 2015 ? 01:11:39 /home/Oracle/app/Oracle/product/11.2.0/dbhome_1/bin/tnslsnr LISTENER -inherit Oracle 6712 6653 0 05:59 pts/1 00:00:00 grep tnslsnr Oracle 17064 1 0 2017 ? 00:19:15 /home/Oracle/app/Oracle/product/11.2.0/dbhome_1/bin/tnslsnr LISTENER_SSPS -inherit

変数$TNS_ADMINが定義されている場合、$Oracle_HOME/network/admin

[Oracle@krw-ssps-db-02 ~]$ env |grep ORA Oracle_UNQNAME=ssps_db2 Oracle_SID=ssps Oracle_BASE=/home/Oracle/database Oracle_HOME=/home/Oracle/app/Oracle/product/11.2.0/dbhome_1 [Oracle@krw-ssps-db-02 ~]$ env |grep TNS TNS_ADMIN=/home/Oracle/app/Oracle/product/11.2.0/dbhome_1/network/admin [Oracle@krw-ssps-db-02 ~]$

はじめに、SQLクエリを作成できます

Connor McDonald · Answer

データベースサーバーへのOSログインがある場合は、次を実行できます。

lsnrctl status

リスナーが提供しているものの詳細を取得します。または、ローカルにログオンできる場合は、データベース自体を照会できます

SQL> select name from dba_services; NAME --------------------------------------- SYS$BACKGROUND SYS$USERS db122XDB db122

ただし、IPアドレス以外にアクセスできない場合は、誰か（DBA）にサービス名を尋ねる必要があります。アレックスが言ったように、tnspingは何も「明らかに」せず、単にあなたがすでに知っているサービス名に接続しようとします。
