Introduction to ISETUP

The ISETUP procedure simplifies the installation process by:

  • Requiring less interaction.
  • Automating most of the procedure.
  • Providing a log of all the activity that takes place, to allow for verification.

ISETUP asks you for the high-level qualifier for your FOCUS data sets. Based on this qualifier and a list of all of the standard data set names (low level qualifiers), ISETUP installs all the necessary FOCUS libraries. The list of low level qualifiers ISETUP uses is in member FOCSNAME in the F.HOME.DATA data set. Although it is not advisable, it is possible to modify the low-level qualifiers of the files. For more information, see Specifying Non-Standard Data Set Names.

About the ISETUP Procedure

The ISETUP procedure is an interactive process that uses ISPF panels.

Important! You must use the version of ISETUP that comes with your FOCUS release to install FOCUS.

Installing without the use of ISETUP is no longer supported. Additionally, you cannot use previous versions of your installation JCL to install FOCUS.

You must execute ISETUP from the ISPF command shell.

You should not use ISETUP to overwrite your current production FOCUS data sets with new versions.

Note: After running ISETUP, you will have to install the new FOCUS License key in order to verify your installation. For more information on requesting and installing your FOCUS license key, see ibi FOCUS License Keys.

Overview of the ISETUP Procedure

This topic provides a high-level overview of the installation procedure and the steps that may be needed after running the installation procedure.

  1. Execute the ISETUP procedure from the ISPF command shell.
    1. Fill in the information requested on the screens displayed by ISETUP.
    2. Submit the JCL created by ISETUP when ready to proceed.
    3. Verify that the ISETUP job was successful by examining the completion codes for each step.

    When this is complete, you have a basic test environment with the FOCUS installation or maintenance applied which is ready to be tested using the verification standards of your site.

  2. After successful testing of the FOCUS release or maintenance, move the test environment to production according to the standards of your site.

Overview of Manual Steps Following ISETUP

The following features are not installed by ISETUP. For these features, you must follow the instructions in the FOCUS Installation Guide for your current production version of FOCUS:

  • The number of cache pages.
  • FOCPARM member of ERRNLS.DATA data set.
  • FOCPROF member of ERRNLS.DATA data set.
  • IBITABLA member of FOCCTL.DATA data set.
  • The FOCUS Menu.
  • The FOCUS Toolkit.
  • Simultaneous Usage facility (SU).
  • User Exits.
  • IBI Subsystem (the Subsystem name, however, is preserved).
  • HiperBudget.
  • CA-ACF2 Interface.
  • SU Security Interface (SUSI).
  • NLS configuration.
  • Maximum number of data exceptions.
  • Data Adapters (Interfaces, for example, Db2 or ADABAS).

    Important: All data adapter files are included and allocated in FOCUS once you run ISETUP. However, using the instructions in the relevant Installation Guides for those data adapters, you must reinstall every data adapter to which you want to have access in the installed version of FOCUS.

If you run FOCUS out of LPA libraries, you must do the following:

  1. Copy all the reentrant modules back into FOCLIB.LOAD from FOCLPA.LOAD. (Use JOB JFSCPBCK.)
  2. Run ISETUP.
  3. Copy the reentrant modules from FOCLIB.LOAD back into FOCLPA.LOAD. (Repeat JOB JFSCPLPA.)
  4. Delete the reentrant modules FROM FOCLIB.LOAD. (Repeat JOB JFSDELPA.)
