Understanding the Install System
The BMC Software Install System is an ISPF application that helps you
generate a set of batch jobs in job control language (JCL). You use the
installation batch jobs to unload and install products from a distribution tape.
The Install System guides you through the installation process, allowing you
to accept or change defaults along the way. You can readily access Help from
each panel by pressing
F1.
You can install multiple BMC Software products on one DB2 system at a
time. You can request different product installation paths as you go through
the installation panels. For example, you can request a Full installation of one
product and a Maintenance installation of another.
Merging Data Sets from Multiple Tapes
You can install products from various BMC Software tapes (such as SIS,
UIS, TIS, DIS, and EDP) during a single Install System session. You
accomplish this by using the COPY REPLACE option in the JCL that you
use to unload the tape.
When you use a merged data set with the Install System, the installation
panels list all of the tape volume serial numbers (VOLSERs) and products
that are available in the merged data set. For more information about merging
distribution tapes, see “Unloading the Install System” on page 2-6.
Understanding Checkpoints
The amount of time that is required to install BMC Software products
depends on several factors, including the number of products that you install,
the installation path that you choose for each product, and the complexity of
each product. By taking checkpoints at predetermined points, the Install
System enables you to interrupt the installation at any time.
When you resume the installation process, the Install System displays a list
of the checkpoints that were taken before the interruption. The Install System
also saves the options that you specified before the interruption to an ISPF
profile. (For more information about the ISPF profile data set, see
“Installation User Profile” on page 1-19.) If the Install System is unable to
perform the save, no checkpoints will exist. You can return to any checkpoint
or begin the installation again, which removes all checkpoints that were taken
in the previous session.
