Migrating the configuration of Infrastructure Management cells

This section details how to migrate your existing KB to the latest standard 11.3.01 KB.

Note

You must migrate and merge your KB only if the KB and the mcell.conf file located in the MCELL_HOME\etc\cellName directory contain any customizations.


Your existing KB might contain customizations, such as class definitions and rules that are unique to your environment, so you must migrate and merge these customizations with the new 11.3.01 standard KB. After you merge your KB, it contains the following components:

  • Definitions from your existing KB
  • New definitions from the latest KB

You must do this merger before you start the server upgrade because the upgrade process requires the KB to be current. You must migrate every KB in your TrueSight Infrastructure Management implementation. The migration process is a combination of several configuration steps.

Validating the KB

If the compilation of the TrueSight Infrastructure Management presentation cell's KB fails, resolve the compilation errors, and recompile the cell by using the following steps:

  1. Check for conflicts. 
    The mmigrate utility displays the conflicts in the Command-Line Interface output. The conflicts are also marked clearly in the merged source files.
  2. Ensure that the KB compiles.
  3. Run your own functional test scenarios.

If the TrueSight Infrastructure Management presentation cell fails to start, check the output messages, correct any errors, and then start the TrueSight Infrastructure Management presentation cell.

Adding the clone cell KB directory to the unique file path for merged KBs

On the TrueSight Infrastructure Management Server host, create a unique file path for the cell that will be upgraded. The file path must follow the following hierarchy:

topLevelDirectory\mergedKB\server\etc\cellName

where,

  • topLevelDirectory can be any directory
  • mergedKB is a required sub-directory, but you can give it any name
  • the specific directory path server\etc\cellName is required
  • cellName is the name of the cell to be upgraded

Note

Your system might already have this file path defined if you had upgraded to TrueSight Infrastructure Management 10.0 from an earlier version.

Copy or move the KB directory of the clone cell to the corresponding topLevelDirectory\mergedKB\server\etc\cellName file path. The server upgrade routine asks for the file path when you upgrade to TrueSight Infrastructure Management.

Migrate KBs using the mmigrate utility
