You can run Prerequisite Scanner manually
from the command line and enter the relevant input parameters for
the script.
Before you begin
Prerequisite Scanner uses
a multicharacter code,
Product_Code,
to identify the integration services for which to run the scan. The
JazzSM_Image_Home/PrereqScanner/codename.cfg file
contains the name value pairs to represent the product code for the
integration service. This table outlines the product codes for the
integration services.
Table 1. Product
codes for integration services
| Integration service |
Product code |
| Dashboard Application Services Hub |
DSH |
| Tivoli® Common
Reporting |
TCR |
| Common Jazz® for
Service Management requirements,
for example, temp directory disk space or libraries for Installation
Manager. Remember: Specify the product code for the common requirements
in addition to one or more product codes for the integration services.

About this task
Prerequisite Scanner uses
environment variables to indicate which set of prerequisite properties
to check for based on the integration service’s component being installed
the target system, or whether it is a fresh installation or an update
to an existing environment.
Table 2. Prerequisite Scanner environment
variables for Jazz for
Service Management
| Integration service |
Scenario |
Environment variable |
| All integration services in Jazz for
Service Management Version
1.1.0.2 |
Fresh installation or update existing installation |
JazzSM_FreshInstall |
Procedure
-
On each target machine, open the command window and change
to the JazzSM_Image_Home/PrereqScanner directory.
-
Set the value for the
JazzSM_FreshInstall environment
variable; for example to scan an existing Jazz for
Service Management before
applying Fix Pack 2:



export JazzSM_FreshInstall=False

set JazzSM_FreshInstall=False
-
Run the Prerequisite Scanner script
file, prereq_checker, as follows:
prereq_checker.bat|sh
"Product_Code [Product_Version][,Product_CodeN [Product_VerN]]..."
[detail] [xmlResult] [outputDir="ips_output_dir"]
- "Product_Code [Product_Version][,Product_CodeN] Product_VersionN]]"
- Specify at least one required Product_Code parameter
to identify the integration service for which to run the scan and
the associated configuration file, as specified in Table 1.
- Only specify the Product_Version parameter, which is
associated with the Product_Code parameter, when you want to scan
the target environment for an earlier version of the integration service. The Product_Version parameter is the 8-digit code to represent the version,
release, modification, and level, with two digits for each part of the code; for example, 3.1.3.0 is
03010300.
- When you want to scan the environment for multiple integration
services, specify the associated Product_Code parameters
each separated by a comma.
Important: When you set more
than one Product_Code parameter
with the optional Product_Version parameter,
enclose the parameters in quotation marks. If you do not, the scan
fails.
- detail
- Specify this optional parameter to display detailed results of
the scan in the command window.
Important: Do not enclose
this parameter in quotation marks.
- Prerequisite Scanner also
saves these results to the ips_output_dir/result.txt file.
It saves the results to the text file regardless of whether you set
the detail parameter.
- outputDir="ips_output_dir"
- Specify this optional parameter when you want to specify the output
directory for the result.txt, result.xml,
and precheck.log files. If you do not set this
parameter, the default output location is JazzSM_Image_Home/PrereqScanner directory.
- You must use the parameter to specify a location, if you choose
to run Prerequisite Scanner from
a CD, DVD, or read-only network drive. You must have write permissions
to write to the ips_output_dir directory; otherwise, Prerequisite Scanner fails.
Important: If the output directory does not exist, or Prerequisite Scanner creates
the directory. You must have write permissions to create or write
to the output directory in which or Prerequisite Scanner saves
the files.
- xmlResult
- Specify this optional parameter when you want to output the results
to the ips_output_dir/result.XML file.
Results
Possible results from running Prerequisite Scanner in
the target environment are as follows:
- Fail
If the target environment does not meet any of the prerequisite
checks, Prerequisite Scanner returns
an overall FAIL result for the environment. The tool
displays the scan results for the individual prerequisite properties
in the command window.
If Prerequisite Scanner returns
this result, take the appropriate actions; for example, install the
missing operating system packages, increase disk space for the file
systems, or modify the configuration settings of the target environment
to match the expected values in the scan results.
- Pass
If the target environment meets all prerequisite checks, Prerequisite Scanner returns
an overall PASS result for the environment.
If Prerequisite Scanner returns
this result, you can install Jazz for Service
Management.
