Answer

The Java class RootAdmin has a public interface that allows you to provide command options to get certain information about each service type and to perform specific activities that are associated with each service.

Besides the administration of the services, the following useful information can be captured by using the public interface of the RootAdmin class.

• memory usage (service and connection pool)
• connection pool status (size of connection pool, current connection usage)
• database pool status (connections in use, maximum connections possible)
• thread names and count per service / process
• session cache information

Running the RootAdmin class without options, shows the 'Usage Information':

$JAVA_RT com.ibm.ccd.admin.common.RootAdmin

Usage: RootAdmin -cmd=<cmd> [-host=<host>] [-svc=<svc name>] [-type=<type>]
See config file: <WPC INSTALL DIR>/etc/default/admin_properties.xml
1/ to start a service: -cmd=start -host=<host> -svc=<svc name> -type=<svc type>
where <svc type> is:
-admin
-appsvr
-eventprocessor
-queuemanager
-scheduler
-workflowengine
and <host> is:
-jonas1
2/ to stop a service: -cmd=stop -svc=<svc name>
3/ to stop a thread: -cmd=stop_thread -svc=<svc name> -thread=<thread number>
4/ to abort a service: -cmd=abort -svc=<svc name>
5/ to check a service: -cmd=check -svc=<svc name>
6/ to get the status of a service: -cmd=status -svc=<svc name>
7/ to get the list of services: -cmd=rmi_status
8/ to unbind a service: -cmd=unbind -svc=<svc name>
9/ to stop all local services: -cmd=stop_local

The service name for the option "-svc" can be found by going to $TOP/logs/
here you will see the directory names for the respective service types that include also the host name.

example:

The directory for the appserver process under $TOP/logs has the name "appsvr_Jonas1", then this name needs to be supplied to the option "-svc"

$JAVA_RT com.ibm.ccd.admin.common.RootAdmin -cmd=status -svc=appsvr_Jonas1

The resulting HTML Output from this command can be put into a file and is readable by an Internet Browser.
