Hello Steemians, today i will show you how to install a PTF in the z/OS, mainframe Operating System:

What’s a PTF?

Program Temporary Fix

Source: https://searchdomino.techtarget.com

Steps to install it

You must have basic knowledge of: SMP, JCL, ISPF and FTP use, i invite you to read a little about it, i will write about all these topics soon.

• Access SMP

In the option

• OS System Support Options
• SM SMP/E

Type in SMPCSI DATA SET : specify the name of the CSI that contains the global zone:

Check the PTF

To know if the pre-requisites are applied or if the PTF is applied.

In the option:

• 3 QUERY - Display SMPCSI information
• 2 CROSS-ZONE QUERY - Display status of an entry in all zones

Type the PTF.

The status observed in the query are:

• REC = Received , ready to apply
• APP = Applied, can be removed and reapplied
• ACP= they' re already permanent in the z/OS?

If the pre-requisites are applied, the installation continues.

2.- Use an FTP program to transmit the file to the Zos. I'll use FileZilla

1.- Download the PTF to your PC, in binary format.
2.- Transfer to z/OS in the same format.

Then in z/OS, it prepares JOBs, for Receive and Applied in the mainframe, are the two important steps:

JOB

The product suppliers always send you the JOB's or JCL's ready, you just have to customize them and run them.

A- Receive

B- Applied

To verify if the correct installation of the PTF, repeat the process of Verify the PTF and run the test JOBs you have.
