Product library, directories, subsystem, job queue, job description, and output queues
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.
Product library and directories
In a default installation, all editions of WebSphere Application Server for IBM i use the following library and directories:
- QWAS85 library
- Product library
- /QIBM/UserData/WebSphere/AppServer/V85 directory
- Root directory for user data that is common to all editions of the product.
- /QIBM/ProdData/WebSphere/AppServer/V85/ND directory
- Root directory containing product data that is shared by all WebSphere Application Server WebSphere Application Server, Network Deployment profiles. Additionally, the master copies of the files that make up a profile are stored here. Do not modify files under this directory structure.
- /QIBM/UserData/WebSphere/AppServer/V85/ND directory
- Root directory for WebSphere Application Server WebSphere Application Server, Network Deployment profile information. All profiles of WebSphere Application Server, Network Deployment are created under this directory structure.
Subsystem
All editions of the product for IBM i use the QWAS85 subsystem. The subsystem description for QWAS85 is located in the QWAS85 product library. The application server, node agent and deployment manager processes run in this subsystem.
Job queue
All editions of the product for IBM i use the QWASJOBQ job queue. The job queue is in the QWAS85 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 QWAS85 subsystem.
Job description
All editions of the product for IBM i use the QWASJOBD job description. The job description is in the QWAS85 product library. The application server, node agent, and deployment manager processes use this job description when submitted to run in the QWAS85 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 QWAS85 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 QWAS85 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.
Output queues
All editions of the product for IBM i use the QWASOUTQ output queue. The output queue is in the QWAS85 product library. By default, this output queue stores job logs for these processes:
- The application server process
- The node agent process
- The deployment manager process
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.
