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”.
