Follow the instructions described in the chapter Creating an SSH Tunnel to a Compute Node Port. You can connect to the compute node where the database instance is running through a SSH tunnel. Unlock the user "hr": alter user hr identified by hr account unlock Ĥ.Alter the session to use PDB: alter session set container=pdb1.
#UNIVERSAL DATABASE IDE PASSWORD#
Connect to the database as a system user: sqlplus sys as sysdba and enter the password chosen while creating the instance.Login as "oracle" into the compute node.SSH to the compute node of the database.So, unlock the HR user using these steps before using it to connect to the database. You will receive an error "account locked". TroubleShooting Tip: When the database instance is first created, HR user is locked for security reasons. For example., you may use the HR schema which is available by default.ĭB_URL = Compile and Run a Java application: Set the connection string according to your environment as illustrated below.
#UNIVERSAL DATABASE IDE DRIVER#
Download the 12.2.0.1 JDBC Thin driver ( ojdbc8.jar) and 12.2.0.1 UCP ( ucp.jar) or 12.1.0.2 JDBC Thin driver ( ojdbc7.jar) and 12.1.0.2 UCP ( ucp.jar) to a location and add that location to the classpath.Compile and Run Your Simple Java Application Unblock this port by choosing "Access Rules" as shown in Fig.1:Oracle Database Service Console and choose 1521 the port used by SQL*Net to enable.įig.1: Oracle Database Service Console 3. When a database instance is first created, the Oracle Net Listener port (1521) is blocked to ensure network security. Oracle Database Cloud Service support access to Oracle Database on the standard Oracle Net Listener port (1521).The format of the database service name is The SERVICE_NAME is also present in the detailed information section. The HOST or the IP address can be obtained by viewing detailed information of a database instance. For example., Click on "dev" as shown in Fig.1:Oracle Database Service Console Once the database instance is created, you can click on the new instance created to get the database details. Create a new instance by clicking on "Create Service" button. Check out the Fig.1: Oracle Database Service Console Click that button and follow the steps to create a database instance.Īnother way to create an instance is to choose Database from the Dashboard and use Open Service Console that lists all the database services. On the Dashboard, you will find Create Instance" button.

Otherwise, create a new database instance by following these steps.Īfter you sign up for Oracle Cloud, login to your account (). If you already have a database instance created then you can skip this step. Create a Database Instance on Oracle Cloud The following steps will allow a successful connection. Access the Oracle Database Cloud Service from Java SE applications, Java Web applications (i.e., Servlets) and Java EE containers using the Oracle JDBC and the Universal Connection Pool (UCP).
