Installation Instructions

All APARs and PTFs from the website consist of a package of files compacted into a single ZIP file.

Unpacking the downloaded file

To extract the contents, run the downloaded file on your PC (double-click it). The fixes themselves are binary files that need to be transferred as a binary file to your ALCS host. The supporting files are ascii files that can be read on the PC or transferred to the host as ascii files.

Files you may find in the downloaded package

Each APAR package contains a NOTES file (an ascii file with a file name of the APAR file and an extension name NTX) describing the problem and the APAR fix file. The APAR fix file (a binary file with extension name FIX) is a copy of the SMP format APAR fix. Some APAR fix packages contain additional files.

Each PTF package contains a PTF file (a binary file with a file name of the PTF and an extension name PTF) which is a copy of the SMP format PTF fix. They also to contain the NOTES file, which relates to the APAR that the PTF supersedes, so this file has the file name of the APAR, not the PTF. Some PTF fix packages contain additional files.

The possible files are :

.fix - The APAR binary file


.ptf - The PTF binary file
.ntx - The notes file
.rtx - An optional README file
.dtx - An optional documentation file
.itx - An optional installation file
