Question

How can I find out the URL and port for an Oracle database?

Example:

“jdbc:oracle:thin:@host:port:dbName”,”userName”, “password”);

Is there an SQL command or log/configuration file I can look at?

Answer 1

With oracle, there is a tnsnames.ora file which defines database addresses. This file is normally found in $ORACLE_HOME/network/admin and is used by oracle clients like sqlplus or Toad. Here is a sample tns entry:

ORA11 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ORA11)
    )
  )

From this entry you can work out that your jdbc connection string would be:

jdbc:oracle:thin:@hostname:1521:ORA11
