An IBM® i platform uses different configurations than installations of WebSphere® Application Server on other platforms.
This topic describes the product library, directories, subsystem, job queue, job description, and output queues that WebSphere Application Server uses on the IBM i platform.
In a default installation, all editions of WebSphere Application Server for IBM i use the following library and directories:
All editions of the product for IBM i use the QWAS8 subsystem. The subsystem description for QWAS8 is located in the QWAS8 product library. The application server, node agent and deployment manager processes run in this subsystem.
All editions of the product for IBM i use the QWASJOBQ job queue. The job queue is in the QWAS8 product library. The application server, node agent, and deployment manager processes are all submitted to this job queue when you invoke the startServer, startNode, or startManager scripts. The QWASJOBQ job queue is associated with the QWAS8 subsystem.
All editions of the product for IBM i use the QWASJOBD job description. The job description is in the QWAS8 product library. The application server, node agent, and deployment manager processes use this job description when submitted to run in the QWAS8 subsystem.
The QWASJOBD job description has the following default settings:

Use the Request data parameter to specify information to start a WebSphere Application Server profile when the QWAS8 subsystem is started. For more information on how to start an application server when the subsystem starts see Starting the application server environment in the QWAS8 subsystem. You can modify the job description if the values do not meet your requirements. However, you must not change the Allow multiple threads value. Because the product processes contain a Java virtual machine that is multithreaded, this value must be *YES.
All editions of the product for IBM i use the QWASOUTQ output queue. The output queue is in the QWAS8 product library. By default, this output queue stores job logs for these processes:
This queue also stores other spooled files. The public authority to the output queue is *USE. This setting ensures that the user profile that is specified for the USER parameter (on the SBMJOB command) has the necessary authority to the output queue when it submits the WebSphere Application Server job to the job queue. The default user profile is QEJBSVR.
You might want to clear the output queue periodically if the number or size of the spooled files becomes large.
