How to get SID, Service Name and Port for Oracle database?

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

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.

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.

Is there a way to access this info somewhere?

Thanks

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.

[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_ADMIN is defined, it will override $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

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


[oracle@krw-ssps-db-02 ~]$ ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:50:56:8F:78:59
          inet addr:10.*.*.244  Bcast:10.*.*.255  Mask:255.255.255.192
          ...
