Question

I have installed Oracle 19 c server in system A. i can access Oracle Pluggable Database using Sql Developer with local host. but want to access that Database from System B,in System B only installed Sql Develper.

1)what need to Change in System A for Remote access? 2)Do need any another files or Software other than sql developer to Connect Remote Oracle Database in System B? if need which have to install ?

Answer 1

You need to set up a listener, by default Oracle will use your host name and port 1521. You need network connectivity from your client (system B) to your server (system A). You would generally set up a tnsnames.ora file on the client so that you can refer to your database using a tns alias, this isn't necessary but can be very handy. In SQL Developer in the client, when you create the connection for the database you would chose your new tnsnames entry or use the basic option and fill out the host etc.

Answer 2

System B should have a way to connect to database on system A. It is the network .

As SQL Developer doesn't require Oracle Client, you should be able to connect fairly easy. Though, you have to know certain details about the database itself.

• create new database connection
• enter username and password
• use "Basic" connection type and provide
  • host name (name of the database server; if you don't know it, use its IP address)
  • port (usually 1521)
  • SID or Service name

That should be all.
