如何获取 Oracle 数据库的 SID、服务名称和端口？

Question

提问by bobetko

I have oracle database running on address xx.xx.xx.xx I know login, password and initial catalog

我在地址 xx.xx.xx.xx 上运行 oracle 数据库我知道登录名、密码和初始目录

I am trying to set up new connection in Oracle SQL Developer so I can access this database to take a look at it. In order to do that, I need to know SID or Service Name.

我正在尝试在 Oracle SQL Developer 中设置新连接，以便我可以访问该数据库以查看它。为此，我需要知道 SID 或服务名称。

Long time ago I would run TNSPing.exe to get service name, but this program is not available any more. Oracle is not distributing it.

很久以前，我会运行 TNSPing.exe 来获取服务名称，但该程序不再可用。Oracle 不会分发它。

Is there a way to access this info somewhere?

有没有办法在某处访问这些信息？

Thanks

谢谢

If you have an OS login to the database server you can run:

如果您有操作系统登录到数据库服务器，您可以运行：

lsnrctl status

lsnrctl 状态

to get details of what the listener is offering out. Or you can query the database itself if you can logon locally

获取听众提供的内容的详细信息。或者如果可以本地登录也可以查询数据库本身

SQL> select name from dba_services;

NAME
---------------------------------------
SYS$BACKGROUND
SYS$USERS
db122XDB
db122

But if you have no access other than the IP address, then you'll need to ask someone (DBA) for the service name. As Alex said, tnsping doesnt "reveal" anything, it simply tries to connect to a service name that you already have knowledge of.

但是，如果您除了 IP 地址之外没有其他访问权限，那么您需要向某人 (DBA) 询问服务名称。正如亚历克斯所说，tnsping 不会“显示”任何东西，它只是尝试连接到您已经知道的服务名称。

'Cause you've said that you have "I know login, password and initial catalog". Then I said:

因为你说过你有“我知道登录名、密码和初始目录”。然后我说：

Get Oracle SID: $ ps -ef | grep pmon; (or $ cat /etc/oratab- format: ORACLE_SID:ORACLE_HOME)

获取 Oracle SID: $ ps -ef | grep pmon; （或$ cat /etc/oratab-格式：ORACLE_SID:ORACLE_HOME）

Get Service Name: $ cat $ORACLE_HOME/network/admin/tnsnames.ora. With tnsnames.ora format, you can cat SERVICE_NAME

获取服务名称：$ cat $ORACLE_HOME/network/admin/tnsnames.ora. 用tnsnames.ora格式，可以cat SERVICE_NAME

net_service_name= 
 (DESCRIPTION= 
   (ADDRESS=(protocol_address_information))
   (CONNECT_DATA= 
     (SERVICE_NAME=service_name)))

In order to execute tnsping, you can install Oracle Client appropriate to your machine.

为了执行 tnsping，您可以安装适合您机器的 Oracle 客户端。

If you have access to the server, then you can determine how many processes the listener is running, what IP addresses and ports it is listening to. An example for Linux.

如果您有权访问服务器，则可以确定侦听器正在运行的进程数、侦听的 IP 地址和端口。Linux 的一个例子。

[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

If the variable $TNS_ADMINis defined, it will override $ORACLE_HOME/network/admin

如果$TNS_ADMIN定义了变量，它将覆盖$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 ~]$

For a start you can make a SQL query

首先，您可以进行 SQL 查询

select * from v$listener_network;

LOCAL LISTENER  (ADDRESS=(PROTOCOL=TCP)(HOST=krw-ssps-db-02)(PORT=1521))
SERVICE NAME    ssps_db2
SERVICE NAME    ssps_db2
