How to Change a Database Link Password

How to Change a Database Link Password

A database link allows you to access another database from the Oracle database. The remote database does not have to be an Oracle database. The link can be used to access the tables and views of the remote database using the Select, Insert, Update or Delete statements. The database link can be created with a static password. However, once this password is created, it cannot be altered. Instead, you must drop the original database link and create a second one with the new password.

Difficulty: Moderately Easy

Instructions

1.      Step 1

Open the SQL*Plus application by typing "sqlplus" at the command line.

2.      Step 2

Drop the current database link with the "DROP DATABASE LINK name;" statement.

3.      Step 3

Re-create the database link and change the password by typing the following statement at the "SQL>" prompt:

CREATE DATABASE LINK name CONNECT TO schema IDENTIFIED BY user USING "newpass";

Change "name," "schema," "user," and "newpass" to reflect the information for your database link.

4.      Step 4

Test the link by typing the following statement at the "SQL>" prompt:

SELECT * FROM table@name;

Change "table" and "name" to reflect the information for your database link.

5.      Step 5

Type "exit" to close the SQL*Plus application.
