How the BrightStor Plug-In Works

The coexistence utility runs the BrightStor plug-in to scan the computer for CA BrightStor registry keys and executables at the end of a CA ControlMinder installation and whenever the utility runs, as follows:

1. Queries the following registry keys for existence:

   HKLM\SOFTWARE\ComputerAssociates\BrightStor ARCserve Backup\UniversalClientAgent\Common
   HKLM\SOFTWARE\ComputerAssociates\Cheetah\UniversalClientAgent\Common
   HKLM\SOFTWARE\ComputerAssociates\BrightStor Enterprise Backup\UniversalClientAgent\Common
   

   When the first registry key exists, the plug-in:

   • Reads the value of the Path entry
   • Returns the following executable pathname:

     FilePathFromRegistry\UnivAgent.exe
     

   • Creates a SPECIALPGM resource of type DCM

     This is the default action as defined in the response file.

2. If the plug-in cannot find any of the registry keys in Step 1, it queries the following registry keys for existence:

   HKLM\SOFTWARE\ComputerAssociates\BrightStor ARCserve Backup\Base\Path
   HKLM\SOFTWARE\ComputerAssociates\Cheetah\Base\Path
   HKLM\SOFTWARE\ComputerAssociates\BrightStor Enterprise Backup\Base\Path
   

   When the first registry key exists, the plug-in:

   • Reads the value of the HOME entry
   • Returns the following executable pathname:

     FilePathFromRegistry\carunjob.exe
     

   • Creates a SPECIALPGM resource of type DCM

     This is the default action as defined in the response file.

3. If the plug-in also cannot find any of the registry keys in Step 2, it queries the following registry key for existence:

   HKLM\SOFTWARE\ComputerAssociates\ARCserveIT\Base\Path
   

   If the registry key exists, the plug-in:

   • Reads the value of the HOME entry
   • Returns the following executable pathname:

     FilePathFromRegistry\ASRunJob.exe
     

   • Creates a SPECIALPGM resource of type DCM

     This is the default action as defined in the response file.

4. Queries the following registry keys for existence:

   HKLM\SOFTWARE\ComputerAssociates\CA BAOF\CurrentVersion
   HKLM\SOFTWARE\ComputerAssociates\BrightStor Backup Agent for Open Files\CurrentVersion
   

   When the first registry key exists, the plug-in:

   • Reads the value of the ServicePath entry
   • Creates a SPECIALPGM resource of type DCM for ServicePathFromRegistry

     This is the default action as defined in the response file.

Note: The response file determines the default action that the coexistence utility performs at prescribed stages (what to do before CA ControlMinder installation, after CA ControlMinder installation, and so on).
