In some logs like TRC_USD_SDAGENT*.log the following error messages appear:

110515-22:20:10.4629934L|018440|000026b4|SDAgent   |cafutils        |cafutils            |000000|ERROR  | caf_getRegValue: RegQueryValueEx: caf_service_name: (0) The operation completed successfully.

What does the error mean and how to remove them?



These errors appear because the registry value caf_service_name is not found under registry key HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\Unicenter ITRM\Agent (or HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ComputerAssociates\Unicenter ITRM\Agent on a 64 bits machine).


Registry OK


This registry value is created during installation of ITCM Agent (12.8, 12.9) when command "caf install" is executed.

But, during an upgrade of the Agent (example: 12.5 to 12.8), the command "caf install" is not executed as the caf service is already installed. So, the registry value is not created.


These error messages could be ignored. They do not indicate a problem with ITCM Agent.

In order to remove these error messages, the registry value could be created manually.


The following 2 methods can be used to create the registry value 'caf_service_name':


1- Execute the command "caf install" using the command prompt:

 caf install




2- Execute the following command in a command prompt:

reg ADD "HKLM\Software\ComputerAssociates\Unicenter ITRM\Agent" /v caf_service_name /t REG_SZ /d caf /reg:32 /f


reg add
