Step 5: Preliminary CMS Installation Steps

This step describes the procedures for performing preliminary CMS installation steps. CA ACF2 for z/VM security for CMS has several optional parts. You select these parts in CA‑ACTIVATOR, but ACF2TASK implements them.

Basic CMS security consists of:

• Source mods to CMS text files (assembled in ACF2TASK Step 6). These files are:

  DMSBOP

  DMSCIT

  DMSEXD

  DMSEXI

  DMSNXD

  DMSSOP

  DMSSVT

• CMS nucleus generation with CAXABLD (ACF2TASK Step 7). This adds dynamic hooks and picks up the CA ACF2 for z/VM modified versions of:

  DMSCIT

  DMSEXI

  DMSSOP

  DMSSVT

• CMS MODULE files generation to include CA ACF2 for z/VM code (ACF2TASK Step 8). These modules are:

  EXECDROP

  FORMAT

  GLOBAL

  NUCXDROP

  RESERVE

  This process adds a CA ACF2 for z/VM frontend to the module for FORMAT, GLOBAL, and RESERVE, or picks up the CA ACF2 for z/VM modified version of DMSEXD for EXECDROP and DMSNXD for NUCXDROP.

VSAM security (also included with CMS/DOS security, described below). This protects VSAM files, whether they belong to VM, or VSE. They consist of:

• Basic CMS security as defined in point 1 above.
• CMSDOS segments generation to include our modified code. This picks up the modified version of DMSBOP, which is called for VSAM open processing.

CMS/DOS security (including VSAM security mentioned above in point 2). This consists of:

• Basic CMS security as defined in point 1 above.
• Source mods to CMS text files (assembled in ACF2TASK Step 6). Text files include:

  DMSDLK

  DMSFCH

  DMSOPL

  DMSPRV

  DMSRRV

  DMSSRV

• CMS/DOS segments generation to include CA ACF2 for z/VM modified code. This process picks up the CA ACF2 for z/VM modified versions of the text files:

  DMSBOP

  DMSFCH

  DMSOPL

• CMS/DOS modules generation to include CA ACF2 for z/VM code (ACF2TASK Step 8). These modules are:

  DOSLKED

  PSERV

  RSERV

  SSERV

  This process picks up the CA ACF2 for z/VM modified versions of the text files:

  DMSDLK

  DMSPRV

  DMSRRV

  DMSSRV

  Step 5 is starting.
  Perform some CA ACF2 for z/VM preliminaries for CMS needed for later steps.
  Enter GO to continue or ? for more information.
  

If you respond to this question with ?, you see the following information:

Step 5 initiates actions necessary for later steps when
installing CA ACF2 for z/VM CMS file protection.
 
This step performs the following functions:
 
A. Copies the CAXALOAD file for your CMS release to the
  ACFCMS CAXALOAD file on your local options disk.
 
B. Copies the DMSAC0 TEXT file for your CMS release to the
  DMSAC0 TEXT file on your local options disk.
 
C. Updates the ACFCMS CAXALOAD file, depending on options
  that you selected in step 1 (Update CA ACF2 for z/VM OPTIONS 
  file).
 
D. Puts you in xedit to review and customize the ACFCMS  
   CAXALOAD file.
 
Refer to the CA ACF2 for z/VM Installation Guide for further details.
 
Valid replies and their meanings are:
 
 "GO" (or a null line) to continue with the installation.
 "COMPLETE" indicates you have completed all of the required
    functions this step performs. CA ACF2 for z/VM assumes that
    you have completed everything properly and continues to
    the next step.
 "HELP" displays information on using this exec and
    valid replies for all prompts.
 
Wait for a repeat of the prompt, then enter your reply.
 
Step 5 is starting.
Perform some CA ACF2 for z/VM preliminaries for CMS needed for later steps.
Enter "GO" to continue or "?" for more information.

If you respond to this question with GO, you see the following information:

Do you want to create your initial ACFCMS CAXALOAD and CMS
release‑dependent CA ACF2 for z/VM modules (DMSAC0)?
Reply YES or NO.
The default is YES.

The prompts that CA ACF2 for z/VM displays depend on your responses to previous questions.

Step 5 is complete.
