Question:  

Could you tell why there is two parmlib dataset concatenation functions 2.1.1 and 2.1.2?

 

Answer:  

The following describes in detail the CA Auditor - PARMLIB INFORMATION 2.1.1 

Map and 2.1.2 Status functions. This information comes from the CA Auditor

Online Help panels.

 

2.1.1: 1  MAP         -  Display IPL tree structure

The Parmlib IPL Map Display is designed to:                              

                                                                         

  *  show you explicit and implict Parmlib member references             

  *  identify unknown, unreferenced, and improper members                

  *  tell you the purpose of each recognizable member.                   

                                                                         

Except for certain members used for performance tuning, z/OS only reads  

Parmlib during Initial Program Load (IPL).  Parmlib contains a master    

general member named IEASYS00 and may have alternate general members     

named IEASYSxx, where xx is any two character suffix.  General members   

contain both parameters and references to specialized members.  The      

specialized members are used to name APF and Linklist libraries,         

SMF options, I/O appendages, etc.  The computer operators may be         

allowed to specify alternate general members during IPL, thus activating 

different specialized members and therefore different options.           

                                                                         

The Map function will clarify this complex structure for you as well as  

identifying improper, unreferenced, or unrecognized members of Parmlib.  

                                                                         

This display requires read access to Parmlib as well as to each of the   

libraries which comprise the logical Parmlib concatenation (if used).    

 

2.2.2: 2  STATUS      -  Identify library contents and detect changes  

The PARMLIB Member Status Display will:                                     

                                                                            

  *  explain the function of members in the z/OS Parameter Library          

  *  detect changes made to members of this critical library                

  *  allow you to display the contents of each Parameter library member.    

                                                                            

The z/OS system parameter library is used for APF authorized                

library specification, SMF options, system linklist specification,          

z/OS UNIX specifications, and a number of other critical functions.         

                                                                            

This display is designed to help you detect changes to this important       

system library by calculating a sophisticated type of hash total on the     

library's contents each time an CA Auditor user                             

requests the display.                                                       

                                                                            

Any changes found by you or other CA Auditor users will                     

be shown.                                                                   

                                                                            

This display requires read access to SYS1.PARMLIB as well as to each of the 

 

libraries which comprise the logical Parmlib concatenation (if used).
