Re-installing IOF Release 8G
A new spin level of IOF 8G can be installed by executing the new MPI file and specifying a new IOF level. The default initial IOF level is level 0. We suggest using level 1 or the next higher level when re-installing a new MPI.
Allocate the Mainframe MPI fileIf IOF is currently running on your system, then the old MPI file may already be allocated. You can download and re-use the old MPI file.
Allocate the MPI file on your OS/390 or z/OS system. Any dataset name can be used, but we recommend that you use a three level dataset name. The DSNAME prefix (top level) should be the same prefix that will be used for the IOF/TSO distribution datasets. The second level should be "IOFT8G0". The bottom level should be "MPI".
All of the new distribution libraries loaded from the MPI file will use the same media placement values as the new MPI file allocated below (volume serial, SMS values, etc.). A blank volser requests allocation on any available volume mounted with the USE=STORAGE attribute.
Use ISPF Option 3.2 to allocate the MPI dataset. The example below allocates the IOF/TSO dataset for release 8G using a prefix of "SYSIOF".
Download the MPI FileThe MPI file can be FTP-ed directly into the pre-allocated MPI mainframe file if you have mainframe FTP capability. You can alternately download the MPI file to a PC and upload from the PC to the mainframe. Whatever upload method you use, the transfer type must be BINARY.
The JCL below downloads the MPI file using the MVS batch FTP command.
The password will be supplied in response to your 8G order. Both username and password are case sensitive, and must be entered exactly as supplied.
Interactive FTP commands are shown below. . The password will be provided in response to your 8G order. Both username and password are case sensitive, and must be entered exactly as supplied.
If you prefer, you can download the MPI file to your PC using your browser and then upload it from your PC to the mainframe. Be sure to specify binary format when uploading to the mainframe.
The username is: ioft8g
The password is provided by email in response to your 8G order. Both username and password are case sensitive, and must be entered exactly as supplied.
After entering the correct username and password, click on the browser's "SAVE..." option to download the MPI file.
The dialog is self documenting. It prompts you for a few required parameters. It extracts the IOF distribution datasets and saves them in MVS datasets you control. When installing from a previous version of IOF, it copies your old IOF options to the new options dataset. Less than five minutes is normally needed to run the MPI dialog.
The dialog builds a TO DO list in member $$TODO of the new INSTALL dataset. This list describes all the tasks required to complete installation of the new release. It references the IOF Installation Guide for additional information. $$TODO is only a page or two long and is specifically tailored to your site. Allowances are made for your previous release of IOF and for many of the options you specified.
Generate and Test the New ReleaseFollow the instructions in the $$TODO member of the new INSTALL dataset to complete generating the new release. It is a good idea to print $$TODO and use a highlighter to check off each paragraph when it has been successfully done.
Release 8G has several new functions as described in the November 2020 Newsletter. Support for z/OS V2R4 is described in the September 2019 Newsletter. The new options will not appear on the IOF Option Menu unless users are authorized to them. $$TODO provides information about how to authorize the new functions. Virtual Help Desk problem number PC09 provides specific information about how to cause IOF options to be shown on the IOF Option Menu.
The new release can be tested in parallel with an existing version of IOF. The same SVC or ESR can be used. The $$TODO member describes testing techniques.
