Maintenance Philosophy

CA ACF2 for z/VM supplies a special control file to simplify the CP and CMS maintenance of your system. The CAXALOAD control file has a filetype of CAXALOAD. We refer to it as a CAXALOAD control file. It contains input data for a CMS module name CAXALOAD that is a front‑end of HCPLDR. The control file does two things. It implements the base CA ACF2 for z/VM support in object‑code‑only form, but not entirely. Source code updates in entry points, instead of source code intercepts, implement a number of optional CA ACF2 for z/VM CMS updates. As a result, you do not need to reassemble CA ACF2 for z/VM intercepted modules. Secondly, the control file overrides CP and CMS LOADLIST execs without modifying them.

For details on these special control files and the CA ACF2 for z/VM modules that use them, see Generating a CP and CMS Nucleus Using CA ACF2 for z/VM.
