In this next series of videos, we're going to examine the various methods a vendor can use to ship products and service and explain the philosophies for each method. There are several sources of SYSMOD as you may remember from the last video, some SYSMODs are distributed to you, from IBM when you order products or service, or when services are automatically sent to you. Other SYSMODs may be provided to you from IBM on an emergency basis, as is typical with an APAR SYSMOD that fixes the problem that you're experiencing. Still, other SYSMOD may be generated locally or provided to you by vendors other than IBM. Now, this class looks in detail, are the installation of a new level of z/OS system. However, that is not the only software that must be considered. Four categories of software exist. The z/OS product contains multiple software components divided into base elements and optional software features. These are totally replaced by the next z/OS installation. Then there's the IBM products which execute on top of z/OS and which are usually managed in the z/OS SMP/E zone. Optionally, these products may also be updated during z/OS installation. Third, we have IBM products which execute on z/OS but are not in the z/OS SMP/E zone. This includes things like CICS, IMS, DB2, and NCP family of associated products. These are not updated by z/OS installation. Then finally we have ISV or Independent software vendor products, that are maintained separately from IBM products and use various installation methods. There are two z/OS installation offerings entitled by z/OS license, ServerPac, which replaces older system libraries, and custom-built productive delivery option or CBPDO, which updates system libraries. IBM also supplies the SystemPac offering, for which a customer pays a fee. The content and method of the application are very similar to ServerPac, but extra tailoring of the new system is done by IBM to simplify the skills and reduce the time needed to perform an installation. z/OS software components are packaged as base elements or as optional features as we've said. What are they? Well, Base Elements deliver essential z/OS operating system functions. These are components that are automatically included in all z/OS ServerPac orders. They are always shipped in a ServerPac package. Non-Priced features are optional free components that must be explicitly ordered to be included with the ServerPac. Unlike Base Elements and Non-Priced features, Priced features support dynamic enablement. All priced features are always shipped with a ServerPac order. Those price features ordered will be automatically enabled during ServerPac installation while the others remain disabled. The exclusive attributes may affect which components are included in a z/OS order. Exclusive means this product is only available when ordered as a z/OS component, whereas non-exclusive is a standalone product, identical in function to the z/OS component and it can be ordered and installed as an alternative. Now, NLS, or national language support is provided for selected products and it's provided in 14 languages. There are two standard delivery options for z/OS. Those of ServerPac and CBPDO. ServerPac is a software delivery package consisting of products and services for which IBM has performed the SMP installation steps and some of the post SMP/E installation steps. To install it, you use the custom pack installation dialogue. This is usually done using software upgrade where system control files from previous systems are used. Alternatively, full system replace ensures everything is installed independent of the old system. It requires some customization work after installation. CBPDO is a software delivery package consisting of uninstalled products and unintegrated service. You must use SMP/E to install the individual z/OS elements and features and their service before you can IPL. Now let's take a look at the contents of a ServerPac. ServerPacs, when installed, replaces a complete z/OS system or subsystem. ServerPac is provided by system or subsystem type. That is, you get a separate ServerPac for each z/OS or subsystem. You select the products you want included in your ServerPac system or subsystem from the product catalog. If you choose tape delivery, when you ordered your ServerPac, you'll receive a box containing the ServerPac system tapes, the ServerPac documentation, and any publications or client code CDs for the products installed in your order. The ServerPac installation Dialog is used to install the ServerPac order. The first step is to unload the Dialog from tape. Then you receive the order into the Dialog and use the Dialog to tailor the ServerPac configuration to match your own system environment. The Dialog will use the Tailored Configuration to generate a Customized Installation Job stream that will create a new target system, from the system tapes. You must place your order using ShopzSeries to choose internet delivery. When your order is ready for download, you'll receive an email from IBM. When you log on to ShopzSeries to access your order, the download pages are dynamically built. You can either download your order directly to host your ServerPac Dialog or download to your workstation first using download director in ShopzSeries and then upload it to the host. The Dialog server option will generate a receive job that uses the SMP/E GIMGTPKG utility to retrieve your order directly from the IBM server. The GIMGTPKG will replace the data in your Downloaded Filesystem. The Download Filesystem option will generate a RECEIVE job that will retrieve your order from a Download Filesystem after you've uploaded it from your workstation. If you chose to download it to your workstation in the first place. Later, the Download RESTORE job will use the SMP/E GIMUNZIP program to load your new target systems volumes from the download file system. In the next video, we'll then move on, to take a look at the custom pack family.
