The ADCD is built on a twice per year schedule typically coinciding with the release of new versions of z/OS. The ADCD is created to provide qualified Independent Software Vendors (ISVs) with the latest z/OS System along with associated middleware products at the latest available maintenance level. The z/OS ADCD can run under the IBM's z System Personal Development Tool (zPDT).

NOTE: There is an annual US $900 subscription fee for the use of the ADCD Software distributions. This annual fee covers the z/OS, z/VM, and z/VSE and Parallel System Starter System Software stacks and is regardless if one, two, or all four ADCD stacks are requested.

Important: Important information is found in this disclaimer so Please READ the Disclaimer!!

Db2 12 now supports encryption of Db2 data with z/OS DFSMS data set encryption, and function level 506 introduces new policy controls for managing of key labels. For more information go to URL: DB2 Administration Tool(DM) and DB2 V12 with V12R1M506

The option to use Secure SSL/TLS for TN3270 has been provided with this ADCD release. We know the newer versions of PCOMM, after V6.0, will not require any special action to use SSl/TLS and most third party emulators will work as well. We believe the most current version of PCOMM is V13 and it will only run on Windows 10 and above. If you still have the Windows 10 box you should try it out. If you are using a third party TN3270 emulator then you should check with owner of the third party TN3270 emulator for assistance with implementing SSl/TLS.

USER.** libaries changed to use the ADCD release level &SYSVER, USER.Z25A, to provide uniqueness based on ADCD release level.

Console member in PARMLIB updated to allow Health Checker messages to roll off.

License

The ADCD is a customized bundle of z/OS and related products. It is not an IBM program product and is not supported as a product. The intent of the ADCD is to allow a user a way to quickly implement a z/OS system in order to concentrate on application development. In general choice of parameters and customizations are default install options with some changes due to user experiences.

Approved ISVs with zPDT based systems will need to have agreed to the ADCD license agreement, and have a signed System z Developer Discount contract on file with IBM prior to receiving a copy of the z/OS ADCD. All license and agreements are done through the System z Developer Discount offering.

System Requirements

The currently supported ADCD environments is:

• z/OS V2R5 December Edition of 2021 under zPDT

For information on the zPDT Version 10.1 release, please see zPDT What is New

Customization Help and Location of Product PGMDIR's

A great deal of effort has gone into the ADCD to customize the products. However, you may find some products that are not fully customized or are customized with options that you need to change. Included in this release, are files in the format of p.SVSC.l where p=product HLQ and l=library name. The purpose of these files is to provide PGMDIR's, README, and INSTALL instructions. This ADCD is built from a driver system that uses different volume and library names. Thus, you will notice that the names referenced in the SVSC files are different than the ADCD. You may need to make translations on names to implement in the ADCD. Included on the RES1 volume are datasets with HLQ of MVS.ZOSRxx that document MVS. The MVS PGMDIR is contained in this grouping.

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 A5xxxx volumes except for A5SYS1. A5CFG1 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.Z25A.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.Z25A.xxxxxx libraries be backed up regularily. When a new ADCD release is installed the USER.Z25A.xxxxxx libraries can be copied from backups to the new USER.Z25A.xxxxxx libraries to provide assistance in migration of programs and parameters.

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

• LINKLST
• PROCLIB (including TSO procedures)
• CLIST
• ISPPLIB (TSO panels)
• LPALIB
• PARMLIB
• VTAMLST
• VTAMLIB
• VTAM source

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

• USER.Z25A.LINKLIB
• ADCD.Z25A.LINKLIB
• SYS1.LINKLIB

USER.Z25A.xxxxxx libraries have all been built on A5CFG1 which is the only volume that should contain user data.

USER.Z25A.xxxxxx will not be changed by ADCD or System processes; thus, user updates in USER.Z25A.xxxxxx will be retained between release levels. ADCD.Z25A.xxxxxx libraries are allocated on A5SYS1 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:

• Copy the system data from SYS1.xxxxx or ADCD.xxxx to USER.Z25A.xxxxxx
• Edit, compile, or run user program against the USER.Z25A.xxxxxx item
• Re-ipl, recycle system service, or re-logon to TSO

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

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

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.

• All functions of the base z/OS V2R5 December Edition of 2021 are at PUT2112 / RSU2112
• All functions of the CICS TS 5.6 are at PUT2112 / RSU2112.
• All functions of the CICS TS 5.5 are at PUT2112 / RSU2112.
• The functions of the DB2 12 base are at PUT2112 / RSU2112.
• All functions of the IMS 15.1.0 are at PUT2112 / RSU2112.
• IBM Z Monitoring Suite V1.2.0 is at PUT2112 / RSU2112.
