Output Formats - IBM Prerequisite Scanner User Manual

v UNIX: shell with .sh extension
Note: You cannot run the UNIX scripts on Windows systems even if you have
installed a UNIX-like environment on the Windows machines, for example,
Cygwin.
You store evaluators in ips_root/OS, where OS is the name of the operating system,
for example, Windows or UNIX_Linux.
Evaluator files must adhere to the following rules:
v Naming convention for the file name:
[prefix_identifier.]property_name[.suffix_identifier]_compare.vbs|sh
where:
– prefix_identifier is an identifier for a predefined category of prerequisite
properties as outlined in Table 3 on page 4. This prefix identifier is required
by some of the predefined categories.
– property_name is the name of the prerequisite property.
– suffix_identifier is an optional identifier for a subtype of prerequisite properties
as outlined in Table 4 on page 6.
v Optionally pass two input parameters to the script for complex evaluations:
– expected_value, that is, the expected value for the prerequisite property that is
set in the configuration file.
– actual_value, that is, the actual value that the collector discovers for the
prerequisite property on the machine.
v Standard output is as follows:
– "PASS" when the expected value for the prerequisite property is equal to or
greater than the actual value for the prerequisite property.
– "FAIL" when the expected value for the prerequisite property does not equal
the actual value for the prerequisite property.

Output formats

IBM Prerequisite Scanner produces output for the following screen and
human-readable file formats: output to the command-line interface, debugging and
trace log files, and a simple text file for the results.
Prerequisite Scanner saves the scan results and log files to the ips_output_dir
directory. You can set this directory by using the outputDir input parameter when
you run the Scanner. If you do not set this parameter, the default output location is
ips_root.
Note: Prerequisite Scanner creates temporary files during its execution, but these
files are deleted before the Scanner completes its execution. These temporary files
are located in the ips_output_dir/temp subdirectory. The Scanner also deletes the
ips_output_dir/temp subdirectory, unless the subdirectory contains the debug and
trace files that are generated on UNIX systems only.
You can also use the parameter to specify a location, if you choose to run
Prerequisite Scanner from a CD, DVD, or a read-only network drive.
Important: If the output directory does not exist, Prerequisite Scanner creates the
directory. You must have write permissions to create or write to the output
directory in which Prerequisite Scanner saves the files.
