z/OS: Where to perform WAS operations

(ZOS) Where to perform WAS operations

Administer WebSphere Application Server involves the use of both the MVS™ console and the WAS administrative console.

For example:

Use MVS commands issued from the MVS console to start the base Application Server control region, the network deployment node agent, and the deployment manager.
In a base Application Server configuration, start the first server with an MVS operator command.
In a network deployment configuration, after the deployment manager and node agent are active, we can use the administrative console to start and stop application servers.
Workload management starts all servants using Address Space Create (ASCRE).

The following table lists the main Application Server operations tasks and directs you to information that helps you to perform these tasks. The Application Server activities and operations can be performed from:

A z/OS MVS console (most operations)
The Application Server administrative console (some operations)
Telnet client, such as TeraTerm, Putty, or the Microsoft Windows telnet client

TSO/ISPF resource recovery services (RRS) panels can be used to display units of work for RRS, and units of work for CICS . See z/OS MVS Programming: Resource Recovery at http://www.elink.ibmlink.ibm.com/public/applications/publications/cgibin/pbi.cgi for more information about using RRS panels.
