Issue/Introduction

During upgrade of ITCM Agent, some important Windows services (like DHCP client, Windows Event Log etc...) are stopped and restarted.

In log generated by Upgrade following lines appear :

 

Action start 18:46:51: InstallValidate. 

… 

MSI (s) (B4:40) [18:46:53:208]: RESTART MANAGER: Will attempt to shut down and restart applications in no UI modes. 

MSI (c) (C8:38) [18:46:53:208]: RESTART MANAGER: Session opened.

MSI (c) (C8:38) [18:46:59:042]: RESTART MANAGER: Successfully shut down all applications that held files in use. 

 

 

RESTART MANAGER has detected one or some locked files and has tried to restart some Windows services. 

 

                   

Environment

CA Client Automation - All Versions

Resolution

In order to minimize the risk of locked files during CA Client Automation, the following commands should be executed before upgrade in order to stop all ITCM process :

 

REM ---- stop CAF ----
caf stop 
tasklist | find /I "caf.exe" 
IF %ERRORLEVEL% EQU 0 caf kill all 

REM ---- stop cfsystray ----
start cfsystray stop 
ping 127.0.0.1 -n 5 > nul 
tasklist | find /I "cfsystray.exe" 
IF %ERRORLEVEL% EQU 0 taskkill /F /IM cfsystray.exe 

REM ---- stop CA Performance Lite Agent (present in previous release of ITCM) ----
net stop CASPLiteAgent 
tasklist | find /I "casplitegent.exe" 
IF %ERRORLEVEL% EQU 0 taskkill /F /IM casplitegent.exe 

REM ---- stop CAM and CA Connection Broker ----
camclose 
csampmux stop 

Moreover these 2 parameters could be added in the command line used for upgrade in order to avoid Windows component "RESTART MANAGER" to restart some Windows Services in case of detection of locked files : 

 

MSIRESTARTMANAGERCONTROL=Disable MSIRMSHUTDOWN=2

 

 For example these parameters could be added in a new procedure in the package :
