This article describes the WebSphere® Application Server for z/OS® product datasets and recommends a product dataset naming convention.
WebSphere Application Server for z/OS product code resides in MVS partitioned datasets, which contain the product datasets, and MVS Unix System Services file systems, which contain the product directory and its subdirectories. The default high-level qualifier for the product datasets is BBO for the base WebSphere Application Server product, IWO for the WebSphere Application Server optional materials, and DYZ for the Secure Proxy Server.
In this and other articles in the information center, was_hlq is used to represent the high-level dataset name qualifier for a particular set of WebSphere Application Server for z/OS product datasets.
ICH420I PROGRAM BBORSMCT FROM LIBRARY WAS.SBBOLD2 CAUSED THE ENVIRONMENT TO BECOME UNCONTROLLED. BPXP014I ENVIRONMENT MUST BE CONTROLLED FOR DAEMON (BPX.DAEMON) PROCESSING.Although program control is enabled on the z/OS system, the program control extended control bits for the application server's native modules will not be enabled. To prevent or resolve this problem enable the program control bits for all of the native load modules in the SMP/E HTTP Server file system (HFS).

The WebSphere Application Server for z/OS product datasets are divided into target datasets (used during product customization and execution) and distribution libraries (used to "back off" maintenance if necessary).
See WebSphere Application Server for z/OS: Program Directory (GI11-2825) for allocation information about each target library and distribution library. Updates to this information are included in the Preventive Service Planning (PSP) bucket for each release of WebSphere Application Server for z/OS.
In order to continue to run WebSphere Application Server for z/OS while applying maintenance, you must have at least two copies of the product datasets: one for the running application execution environment and one to which service is applied.
We recommend you choose a middle level qualifier for each separate release and maintenance level of WebSphere Application Server for z/OS. This middle level qualifier can reflect a very simple test/production distinction, such as with "BBO.V7PROD.*" or "BBO.V7TEST.*", or can include specific service level information, such as with "WAS.W700102.*" or "WAS.W700103.*".
There are many places where you must specify the product dataset names, so, to avoid undue confusion, use the simplest dataset naming scheme that accomplishes your maintenance goals.
