This function was previously completed by the System Modification Program Extended (SMPE). This paper will provide a “cookbook” approach to the customization for use of Installation Manager for z/OS, and the use of it to complete the installation of WebSphere on z/OS Version 8 and its associated products. It is worth noting, that the procedures described in this document apply to WebSphere on z/OS V8.5 and other related products, as well as Websphere on z/OS V8. In short, this will involve the following steps: 1. Creation of the Installation Manager using the Installation Manager Install kit. 2. Creation of the WebSphere on z/OS V8 filesystem components on a /Service mountpoint. 3. Using the Installation Manager to populate the filesystem. 4. A discussion of a suggested method for properly handling the installation of maintenance. Since the configuration of WebSphere on z/OS using the zPMT component of the WebSphere Customization Toolbox is essentially unchanged from the previous version, this will NOT be covered by this paper. Assumptions Since the use of SMPE should hold no mysteries for the person(s) performing this work, we will assume that the Installation Manager for z/OS Install kit and the WebSphere on z/OS Installation Manager Repository have already been successfully installed using SMPE. We will also assume that enough resources are available for this work to be performed. Some of these jobs require large region sizes and installation specific restrictions on those region sizes, usually implemented via an IEFUSI exit can impair the correct functioning of these jobs. The successful circumvention of these restrictions is left to the installation. The format of this paper is to serve as an aid to getting WebSphere on z/OS properly installed in a maintainable fashion. We will not be discussing the intricacies of either WebSphere on z/OS or the Installation Manager on z/OS. For that information the reader is directed to the appropriate InfoCenter articles for each product.

Creation of the Installation Manager using the Installation Manager Install kit involves relatively few tasks. 1. You must decide which “mode” you wish to use for the install. 2. You should perform some setup on the security system. 3. Creation of the filesystem for the Installation Manager. 4. Creation of the Installation Manager. 5. Verification of the install. Installation Manager mode selection. The Installation Manager may be created in any of three possible modes: admin, user, or group. Admin mode: You must be in uid=0 to run in admin mode. A file in /etc/.ibm/registry points to the Installation Manager binaries, so there can only be one admin mode Installation Manager per system. Any user ID with uid=0 can invoke this Installation Manager. User mode: The userid used when creating the Installation Manager is the only userid that may ever use it. A file in the $HOME/.ibm/registry points to the binaries, so there can only be one user mode Installation Manager per user. Group mode: A group mode Installation Manager may be invoked by any userid connected to the USS group that owns the Installation Manager files. There can be any number of group mode Installation Managers and there can be any number of userids connected to the group. Since many (most) installations restrict the assignment of uid=0 to actual z/OS users, admin mode is probably not the mode of choice for most installations. The restriction to only one user using a user mode Installation Manager makes that mode undesirable for most z/OS installations. That leaves us with group mode as the probable choice. Since this is what the majority of installations will find to be the most usable mode, this is the mode that this paper will use. The use of the other modes involve very simple and few changes, other than who has the ability to use the Installation Manager. When using the Installation Manager in group mode, you need to either: A. If it is a batch job, you can: I. Specify the GROUP= parameter on the JOB card. II. Specify the Installation Manager's USERID and PASSWORD on the JOB card. III. Specify the Installation Manager's USERID on the JOB card without the PASSWORD parameter if you have SURROGAT authority for the USERID. B. If you are using OMVS: I. Use the su command to switch to the Installation Manager's USERID and respond to the password prompt. II. Use the su -s command to switch to the Installation Manager's
