To get to the health state of a deployment, you can use the following code after connecting to the Adminserver over WLST

Node Manager can start a server without requiring you to specify startup options. However, if you have modified your environment; for example, if you have added classes to the WebLogic Server classpath, you must specify startup options before you use the Administration Console to start a server.

Weak JVM performance affects WebLogic domain performance directly. That’s why the host’s CPU and memory usage is very important in terms of improving WebLogic performance. Higher CPU consumption and Garbage Collection duration can cause applications to run slowly, even cause the WebLogic servers facing downtime. JVM instances in a WebLogic need to be monitored constantly and notification/alarm infrastructure must be installed as well.

Navigate as below for WebLogic active sessions monitoring.

Cron allows Linux and Unix users to run commands or scripts at a given date and time. You can schedule scripts to be executed periodically. The cron service runs in the background and constantly checks the /etc/crontab file, and /etc/cron.*/ directories. You can add new crontab defination using with “crontab -e” and list all jobs with “crontab -l”.

WL-OPC (WLSDM OPERATION CENTER) is the operation central and notification system which enables to manage application server infrastructure. You are going to able to manage, organize and visualize with WL-OPC; How to Create a Notification Actions ? WLSDM notifications can be managed from WL-OPC. Application, Datasource, JMS, Server and Domain’s health notifications can trigger the custom scripts. In this article about to restarting the server when the servers states are shutdown.

WebLogic is an Oracle product that performs the role of the application server. The software application is a middleware that connects between back-end applications like databases and related applications with browser-based thin clients. WebLogic is used to develop and deploy J2EE applications. J2EE is the standard platform for developing multitier enterprise applications based on the Java programming language. WebSphere is an IBM software that performs the role of the application server.

Oracle HTTP Server (OHS) is the Web server component for Oracle Fusion Middleware. It provides a listener for Oracle WebLogic Server and the framework for hosting static pages, dynamic pages, and applications over the Web. Oracle HTTP Server and Oracle WebLogic ServerOracle recommends associating Oracle HTTP Server with the WebLogic domain because it enables Oracle HTTP Server to be incorporated into the Administration Console for centralized management and monitoring.

Recently we have published an article about “New Release WLSDM 3.7.1 and WL-OPC 1.2.0 is common available!”. In this blog, we will examine the changes in OID 11g and 12c and how to track the component’s health through WLST and WLSDM. Please read complete blog post about the structure of Oracle Internet Directory and related OID component monitoring in WLSDM.

In this blog, we analyzed Oracle Service Bus and how to Oracle Service Bus Monitoring performance & Diagnostics in WLSDM. Let's start with the Oracle Service Bus structure.
