VMSES/E considerations

This section describes items that should be considered before you install High Level Assembler

VMSES/E is required to install and service this product.
The VMSES/E system-level software inventory and other dependent files reside on the MAINT 51D disk. If multiple users install and maintain licensed products on your system there might be a problem getting the necessary write access to MAINT's 51D disk. If you find that there is contention for write access to the 51D disk, you can eliminate it by converting the software inventory from minidisk to the Shared File System (SFS). See z/VM: VMSES/E Introduction and Reference for information about how to make this change.
You no longer install and service High Level Assembler strictly using the MAINT user ID, but using a new user ID P696234J. IBM recommends that you use this userid, however, you can change the userid name if you wish. If you change this name, you must create a PPF override. Generally, this section of this installation and customization guide assumes that you have used the IBM-recommended userid, P696234J.
If you plan to change the userid, it might be easier to do so during Step 1, substep 6, while you are installing the product.
If you plan to install to minidisks, you should be aware that the saved segment must be built from the installation user ID P696234J. If you want to build the segment from a common user ID, install High Level Assembler using the SFS system, so that the common user ID can access High Level Assembler code when building segments.
