Unable to Start WebLogic Admin Server: Changing Expired Password for Oracle 19c Database Profile
In this article, we will discuss the issue of being unable to start the WebLogic Admin Server due to an expired password for the Oracle 19c database profile. We will cover the key concepts, applications, and significance of this issue, and provide detailed solutions in the form of subtitles, paragraphs, and code blocks.
Key Concepts
WebLogic Server is a popular Java-based application server used for developing, deploying, and running enterprise-level applications. Oracle 19c is a relational database management system (RDBMS) that stores and manages data for WebLogic Server and other applications.
In order to connect to the Oracle 19c database, WebLogic Server uses a database profile, which contains the connection details such as the username, password, and database URL. If the password for the database profile expires, WebLogic Server will not be able to connect to the database and start the Admin Server.
Applications
This issue can affect any application that uses WebLogic Server and Oracle 19c database, such as Oracle Identity Management (OIM), Oracle SOA Suite, Oracle WebCenter, and custom-developed applications.
Significance
Being unable to start the WebLogic Admin Server can have serious consequences, such as:
- Inability to deploy and manage applications
- Inability to monitor and manage the WebLogic Server infrastructure
- Inability to perform backup and recovery operations
- Inability to meet service level agreements (SLAs) and business continuity requirements
Changing Expired Password for Oracle 19c Database Profile
To resolve this issue, you need to change the expired password for the Oracle 19c database profile used by WebLogic Server. The following steps will guide you through the process:
Step 1: Connect to the Oracle 19c Database
Connect to the Oracle 19c database using a client tool such as SQL Developer or SQL\*Plus. You will need the SYSDBA or SYSOPER privilege to change the password.
Step 2: Identify the Database Profile
Identify the database profile used by WebLogic Server. You can find the profile name in the WebLogic Server configuration files, such as setDomainEnv.sh or boot.properties.
Step 3: Change the Password
Change the password for the database profile using the ALTER PROFILE command. For example:
ALTER PROFILE DEV_OIM IDENTIFIED BY new_password;
Step 4: Update the WebLogic Server Configuration
Update the WebLogic Server configuration to use the new password. You can do this manually by editing the configuration files, or by using a script or a tool such as WLST (WebLogic Scripting Tool).
Step 5: Restart the WebLogic Server
Restart the WebLogic Server to apply the changes. You should now be able to start the Admin Server and connect to the Oracle 19c database.
