The JCmon is a native monitoring program, part of the startup and control framework, which can be used to:
• Display a list of the processes
• Enable, disable, and restart the specified processes
• Shutdown a specified J2EE instance
• Enable/disable debugging for a specified process
• Dump stack trace
• Display a list of the ports used by the J2EE Engine
• Activate/deactivate debug sessions
• Increment/decrement the trace level
1. To start the JCmon, log on to the system using <SID>adm and execute the monitor.
# su - <SID>adm <SID>adm> jcmon pf=/usr/sap/<SID>/sys/profile/<SAPSID>_<INSTANCE_ID>_<HOST>.
2. From the main menu, there are 4 menu choices which 0 is to exit the Main Menu. 10 is Cluster Administration Menu which can administer for the whole Java system. 20 is Local Administration Menu which can administer the node that currently connected. 30 is Shared Memory Menu which can perform refresh shared memory and etc.
