Using CIT deployed by LMT9 by other IBM products

Troubleshooting


Problem

IBM License metric Tool (ILMT) deploys Common Inventory Technology (CIT) scanner in so called 'single user mode' which may cause issues for other CIT exploiters. The technote provides workaround for this problem.

Symptom

CIT scans fail when run by other IBM products than ILMT in scenario when on one machine the scanner was installed or upgraded by using 'Install or Upgrade Scanner' fixlet from ILMT.

Cause

To increase security, LMT installs CIT scanner in so called 'single user mode'. In this mode permissions of CIT files and folders are more strict and CIT can be used only by the user who installed it. On Unixes this is root, on Windows SYSTEM user. If other IBM products run CIT scans as another user (even from administrators' group), the permissions may not be satisfactory for the scan to finish successfully.

Environment

Machine where CIT is used by both ILMT and other IBM product (for example TWS).

Diagnosing The Problem

When CIT scan is run by other product than IBM (typically hardware scan - wscanhw) - it fails. After such failure no standard CIT logs are generated.

Resolving The Problem

To change the CIT model of installation from 'single user' to standard one with wider permissions, run the following fixlet on Windows machines: Reinstall_scanner_without_single_user_mode_enabled.besReinstall_scanner_without_single_user_mode_enabled.bes

The fixlet works only on Windows. It performs the following operations:

    1. Backups the list of all registered CIT exploiters on the machine
    2. Removes CIT fully
    3. Installs the latest version of CIT used by LMT (gathered from BigFix FTP) in standard way (without 'single user mode' setting)
    4. Registers back all the exploiters
Please note that the fixlet is provided 'as is' and it is not an official part of ILMT product.
