JPing
The JPing class is a command line utility that allows you to query your servers to see which services are running and which ports are in service. To query your servers from within a Java™ application, use the AS400JPing class.
See the JPing Javadoc for more information about using JPing from within your Java application.
Call JPing from the command line by using the following syntax:
java utilities.JPing System [options]where:
- System = the system that you want to query
- [options] = one or more of the available options
Options
You can use one or more of the following options. For options that have abbreviations, the abbreviation is listed in parenthesis.
- -help (-h or -?)

- -service i_Service (-s i_Service)
- Specifies one specific service to ping. The default action is to ping all services. You can use this option to specify one of the following services: as-file, as-netprt, as-rmtcmd, as-dtaq, as-database, as-ddm, as-central, and as-signon.
- -ssl
- Specifies whether or not to ping the ssl ports. The default action is not to ping the ssl ports.

For example, use the following command to ping the as-dtaq service, including ssl ports, with a timeout of 5 seconds:
java utilities.JPing myServer -s as-dtaq -ssl -t 5000
