Resolution

In order to solve this problem of installation not completed, reapply the CU7 locally (run the command
from a local directory in the target DM machine) following the steps below adding the INSTALLAGAIN option.

Option /INSTALLAGAIN should be added too to give the possibility to install again the patch if it has already been
installed.

1. Close DSM explorer if opened.
2. cfsystray stop
3. Change to directory where the CU7 patch is located:

cd \ITCA\ClientAutomation\Patches\CU7\EM_DM_99112083\99112083

4. Execute the ApplyPTF command below:

applyptf.exe /NODE=<DM_HOSTNAME> /PTF=99112083.jcl /INSTALLNEW /SILENT /INSTALLAGAIN /OUTPUTFILE=99112083.log /DEBUGFILE=99112083.dbg

* Replace <DM_HOSTNAME> by the DM hostname

5. Monitor the ApplyPTF.exe process in the Task Manager -> Detail tab and the 99112083.log with Notepad through the Monitoring icon
until it end showing the line 'Done.'. The ApplyPTF of CU7 may take > 20 mins to complete.

6. caf status

7. Review the logs and attach to the case:

99112083.log
99112083.dbg
postInstall.log
preinstall.log
C:\Program Files (x86)\CA\DSM\<DM_HOSTNAME>.his

C:\Program Files (x86)\CA\DSM\Web Console\webapps\pmengine (if using Patch Manager)
C:\Program Files (x86)\CA\DSM\Web Console\webapps\ams

5- Stop tomcat again
caf stop tomcat
