This chapter describes the procedure for upgrading a managed Oracle HTTP Server from to a latest 12c release from a previous 12c release. The valid starting point for this upgrade are 12c releases 12.1.2 and above.
This procedure assumes that you have the 12.1.2 Fusion Middleware Infrastructure (JRF plus the WebLogic Server) installed and configured on your system.
Before installing the 12c software, shut down all the 12.1.2 server instances except the RDBMS.
Before you upgrade your existing Managed Oracle HTTP Server components, you must first install the Oracle HTTP Server Release 12.2.1.
You need to upgrade the 12c (12.1.2 or 12.1.3) OPSS and IAU (Audit Services) schema using the 12c Upgrade Assistant.
If you are running the Upgrade Assistant from an Oracle home that contains managed domain components, then the WebLogic Component Configuration upgrade option is available.
The post-upgrade tasks include starting the Node Manager, starting the Administration Server, starting the Oracle HTTP Server, and verifying whether the upgrade from 12.1.2 to 12.2.1 is successful.
opmnctl
command to start, stop, and restart Oracle HTTP Server.Server instances in a WebLogic Server production environment are often distributed across multiple domains, machines, and geographic locations. Node Manager is a WebLogic Server utility that enables you to start, shut down, and restart Administration Server and Managed Server instances from a remote location.
On Windows operating systems, it is recommended that you configure Node Manager to run as a startup service. This allows Node Manager to start up automatically each time the system is restarted. For more information, see Running Node Manager as a Startup Service in Administering Node Manager for Oracle WebLogic Server.
Note:
On UNIX platform, do not run Node Manager as the root user.One instance of WebLogic Server in each domain acts as an Administration Server. The Administration Server provides a central point for managing a WebLogic Server domain. All other WebLogic Server instances in a domain are called Managed Servers. In a domain with only a single WebLogic Server instance, that server functions both as Administration Server and Managed Server.
In a development environment, it is usually sufficient to start an Administration Server and deploy your applications directly onto the Administration Server. However, in a production environment, it is recommended that you create Managed Servers to run your applications.
You can use Enterprise Manager Fusion Middleware Control or the opmnctl
command to start, stop, and restart Oracle HTTP Server.
