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 Access Control 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 Access Control installation, after CA Access Control installation, and so on).
