Client Automation assigns each managed computer a CA Technologies-specific Universal Unique Identifier (UUID). It is stored on each computer at the following locations:

x32 Windows registry:      HKEY_LOCAL_MACHINE\Software\ComputerAssociates\HostUUID
x64 Windows registry:      HKEY_LOCAL_MACHINE\Software\Wow6432Node\ComputerAssociates\HostUUID
Linux/UNIX:               /etc/cadmuuid                                   

The Hostuuid can change if any of the following items changes:

Virtual machine :     System ID (a system BIOS attribute) is the only characteristic checked by the algorithm.

Physical computer: 

   ? MAC address compliance  -    If one of the MAC addresses does not match with one of the original MAC addresses of the target.

   ? Hard disk serial number compliance  - If one of the Hard Disk serial numbers does not match with one of the original hard disk serial numbers of the target.

   ? System ID compliance   -  If the System ID does not match with the original System ID of the target.



   How do I lock the Hostuuid for some or All agents.



  CA Client Automation R14                                       



In previous version you could lock the hostuuid by the following steps:

 Windows:        Create a string value LockHostUUID with value “1”, under the registry key HKLM\Software\ComputerAssociates\HostUUID.

 Linux/UNIX:   Create a file named /etc/calockuuid.


The new way to do it in  CA Client Automation R14:  

Once you have installed R14, there will be a new Configuration Policy created under : Default Computer Policy\DSM\Agent      

Lock the host UUID of agent                 Set to TRUE

You can either update the Default configuration Policy and then it will update all machines.


You can create a Custom Policy and only apply it to a single machine or Group.
