Organization of this subsection

(1) Checking the contents of system environment to be deleted
(2) Web Server to be deleted, stopping J2EE Server and performance tracer
(3) Deleting Web Server, J2EE Server, and Performance Tracer

(1) Checking the contents of system environment to be deleted

Check the name of the system environment to be deleted by executing cmx_list_model command with the command prompt.

Command execution example is as follows:

cmx_list_model -m localhost:28080 -u admin -modeltype SERVEREX -all

List of Web systems and logical servers set up on Application Server is output.

Check the following names:

Name of the Web system for allocating J2EE Server to be deleted.
Name of the Service unit for allocating J2EE Server to be deleted.
Logical Web Server name of the Web Server in the Web system to be deleted.
Name of the Logical J2EE Server of J2EE Server to be deleted

(Example of command execution result)

MyPerformanceTracer,PRF,<Host name>,combined-tier,unit1,MyWebSystem
MyJ2EEServer,J2EEServer,<Host name>,combined-tier,unit1,MyWebSystem
MyWebServer,Webserver,<Host name>,combined-tier,unit1,MyWebSystem
MyPerformanceTracer2,PRF,<Host name>,combined-tier,unit2,MyWebSystem
MyJ2EEServer2,J2EEServer,<Host name>,combined-tier,unit2,MyWebSystem
MyWebServer2,Webserver,<Host name>,combined-tier,unit2,MyWebSystem

In any instance where the logical J2EE server name of J2EE Server to be deleted is MyJ2EEServer2, the respective names to be used will be as follows:

Item	Name
Name of the Web system where J2EE Server to be deleted is allocated	`MyWebSystem`
Name of the Service unit where J2EE Server to be deleted is allocated	`unit2`
