Preparing a PTF package for installation

Updates to the compiler are supplied as PTF packages. Before you use these PTF packages to update the compiler, you must download and decompress these packages, and then generate a .toc file.

Before you begin

You must log in as root or have superuser authority.

Procedure

Download the PTF package that you want (for example 13.1.3.1-IBM-xlccmp-AIX-FP001.tar.Z) into an empty directory.
Restore the compressed file and extract the PTF filesets from the downloaded package. To decompress and unpack the tar file, use the following command:
```
zcat package_name.tar.Z | tar -xvf - 
```
Use the command inutoc directory_name to generate a .toc file in the same directory as the unpacked filesets.

Example

The following example shows the steps to prepare the package, 13.1.3.1-IBM-xlccmp-AIX-FP001.tar.Z, located in the directory /compiler/update/, for installation.

cd /compiler/update
zcat 13.1.3.1-IBM-xlccmp-AIX-FP001.tar.Z | tar -xvf - 
inutoc .
