and how it must be installed. A repository can reside on a local directory or on a remote,

reachable server.

Installation Manager installs, uninstalls, modifies, and maintains the software using a

software repository. In doing this, it uses three software locations:

–

Binary location: The directory where Installation Manager is installed.

–

Agent data location (also known as appDataLocation): The directory where

Installation Manager stores data associated with an application, including the

application state and operations history.

–

Object Cache location: Used by Installation Manager to reduce the time when an

operation is performed, which avoids spending time going online to use objects.

Figure 4-2 shows the components of Installation Manager.

4.2 Installing Installation Manager

You must run Installation Manager only on systems on which you install or update product

code. Typically, you need only one Installation Manager on a system because one Installation

Manager can track any number of product installations.

You install Installation Manager through SMP/E, and then use the z/OS Profile Management

Tool (zPMT) to configure your environment, as shown in Figure 4-3 on page 104.

hardware and software prerequisites at the following website:

http://www-01.ibm.com/support/docview.wss?uid=swg27024798

4.2.2 Obtaining an Installation Manager installation kit

The installation kit for Installation Manager has function modification identifier (FMID)

HGIN140, provided within WebSphere Application Server for z/OS Version 8.5. You can also

obtain the stand-alone installation kit in one of the following ways:

 Through a ServerPac or IBM SystemPac® in a ready-to-use format.

Under this method, PTFs must be installed to bring the kit up to Installation Manager

Version 1.5.2, which is the minimum that is required to install WebSphere Application

Server for z/OS V8.5.

 Through a Custom-Built Product Delivery Offering (CBPDO).

In this scenario, you must use the following jobs to install CBPDO:

– GINRECEV to receive the deliverables

– GINALLOC to allocate target and distribution data sets

– GINDDEF to create SMP/E DDDEFs

– GINISMKD to mount the installation file system and create directories

– GINAPPLY to apply the installation kit FMID

– GINACCEPT to accept the installation kit FMID
