Updating an advanced installation using xlfndi

If the XL Fortran compiler has been installed to a non-default directory, you must use xlfndi to install PTFs.

About this task

Note: The xlfndi tool enforces that you install the PTF xlfcmp.15.1.0.ndi fileset before using the tool to install the PTF to a non-default location.

To update a non-default installation, take the following steps:

Procedure

Begin by installing the xlfcmp.15.1.0.ndi fileset included in the PTF. This fileset must be installed first, so that the xlfndi script inside it can be used to correctly install the remaining filesets.
To determine the version number of the xlfcmp.15.1.0.ndi fileset currently installed on your system, run the command:
```
lslpp -l xlfcmp.15.1.0.ndi
```
To install a new version of the xlfcmp.15.1.0.ndi fileset, run the command:
```
installp -aXgd ptf_images_location -e logfile xlfcmp.15.1.0.ndi
```
Create a text file listing the PTF filesets you want to install. This text file must contain the name of a single PTF file on each line. You can use the ls command to do this: ls source_path > ptf_names_file.
For example:
```
ls /compiler/update/*.bff > /home/user/update.list
```
update.list contains all the updated fileset names, one for each line. For example:
```
xlfcmp.15.1.0.1.bff
```
Use the perl command to run the xlfndi script:
```
>>-perl--/opt/IBM/xlf/15.1.0/bin/xlfndi-- -d--source_path-- -u--ptf_names_file-->

>--+--------------+--+-----------------+--+-------+------------->
   '- -e--logfile-'  '- -b--target_dir-'  '- -rte-'   

>--+-----------+-----------------------------------------------><
   '- -version-'   
```
```
perl /opt/IBM/xlf/15.1.0/bin/xlfndi -d source_path -u ptf_names_file [-e logfile] 
-b [target_dir]
```
where:
-d source_path

Specifies the directory where the filesets are located. This path might also be a mounted CD-ROM drive.

-u ptf_names_file

Specifies the text file containing the names of PTF filesets you want to install.

-e logfile

Specifies the name and location of the installation log file. By default, the installation log file xlfndi.log will be stored in your working directory.

-b target_dir

Specifies the directory where the compiler you are updating is installed.

-rte

Specifies that only the runtime component is installed.

-version

Displays the version of the non-default installation tool.
Note: The installation script creates a compressed TAR backup of the compiler files that exist before the PTF update. If a problem is encountered with the installation of the PTF update or with the PTF update itself, you can restore from this backup file target_dir.tar.Z to uninstall the PTF update.

The following example uses the xlfndi Perl script to install all available PTF filesets in the /compiler/update/ source directory to the non-default location, /compiler/xlf/ and writes the installation log file to /tmp/xlf.ndi.inst.log.

Example:
```
perl /opt/IBM/xlf/15.1.0/bin/xlfndi -d /compiler/update/ -u /compiler/update/ptflist
-b /compiler/xlf/ -e /tmp/xlf.ndi.inst.log
```
