Build Structure





Migration Guidelines

The following guidelines will make it easier for you to replace   this level of system software with new levels built the same way.

Only IBM-supplied system software should reside on   C4xxxx volumes   except for C4SYS1.   C4CFG1 contains RACF, IPL, and catalog   datasets that are user dependent.

The ADCD does not contain a generalized migration utility or process.   Each user has unique requirements. It is recommended that you build   a migration plan based on your unique needs.  The ADCD does have   some assistance. The ADCD uses a system of concatenated libraries   (see below) The highest level of concatenation is   USER.Z24C.xxxxxx   The ADCD distributes these libraries empty. It is recommended that   the user place changes or overrides in these libraries. It is further   recommended that the   USER.Z24C.xxxxxx   libraries be backed up regularily.   When a new ADCD release is installed the   USER.Z24C.xxxxxx   libraries can   be copied from backups to the new   USER.Z24C.xxxxxx   libraries to provide   assistance in migration of programs and parameters.

The ADCD is distributed with a standard library   concatenation for the following:


The configured order of concatenation is user,   ADCD developers, and z/OS system   datasets.   For example, the LINKLST concatenation would be as   follows:


USER.Z24C.xxxxxx   libraries have all been built on   C4CFG1   which is the only volume that should contain user data.

USER.Z24C.xxxxxx   will not be changed by ADCD or System processes; thus,   user updates in USER.Z24C.xxxxxx   will be retained between release levels.   ADCD.Z24C.xxxxxx libraries are allocated on   C4SYS1 and are the libraries that are used   by ADCD developers. No RACF rules exist on these libraries; however,   changes to these libraries could destroy customization necessary to   bring up many products. SYS1.xxxxxxx libraries should NEVER be   updated by users or ADCD development.  System libraries should ONLY   be updated through SMP/E install, maintenance processes, or like   processes.

NOTE:   Changes to System libraries or ADCD pre-customization may corrupt   your system and prevent or delay IBM support activites.

The correct procedure for a user update to system data is to:


Removing a user update would be the reverse of the above procedure.

LOADPARMS Options

NOTE:   JES2 should be COLD started the FIRST time you bring up the   system.

Maintenance Service Levels

All the products on the ADCD consist of maintenance that is in a   closed status. A PTF that is still in open status or has other than a   document hold at the time the ADCD was built would not be added to   the ADCD. The following PUT levels may be minus PTFs that were open   at build time. Also some functions may be better than the PUT level   due to the addition of RSUs and individual PTFs. In general the   following is valid.
