Environment

Client Automation 14.5

Cause

In preinstall.log there are these lines :

"Deleting wac folder ... "
[Operation] Folder delete
[Path] D:\CA\DSM\\Web Console\\webapps\\wac
remove_readonly() takes 2 positional arguments but 3 were given
Folder delete status: False
"wac folder deleted succesfully "

"Deleting AMS folder ... "
[Operation] Folder delete
[Path] D:\CA\DSM\\Web Console\\webapps\\AMS
remove_readonly() takes 2 positional arguments but 3 were given
Folder delete status: False
"AMS folder deleted succesfully "

 

Deletion of folders D:\CA\DSM\Web Console\webapps\wac and D:\CA\DSM\Web Console\webapps\AMS were not successfull.

Maybe a running process are still locking some files inside these directories.

Resolution

1- Stop caf

caf stop

caf kill all

 

2- Make sure with Windows Task Manager there is no more running process java.exe with command line like :

 

"C:\Program Files (x86)\CA\SC\JRE\1.8.0_212\bin\java.exe" -Xrs -Dfile.encoding=utf8 -Xms128m -Xmx256m -XX:MaxPermSize=256m -classpath "C:\Program Files (x86)\CA\SC\Tomcat\8.5.56\bin\bootstrap.jar";"C:\Program Files (x86)\CA\SC\Tomcat\8.5.56\bin\tomcat-juli.jar" -Dcatalina.base="C:\Program Files (x86)\CA\DSM\Web Console" -Dcatalina.home="C:\Program Files (x86)\CA\SC\Tomcat\8.5.56" -Djava.io.tmpdir="C:\Program Files (x86)\CA\DSM\Web Console\temp"  -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager  -Djava.util.logging.config.file="C:\Program Files (x86)\CA\SC\Tomcat\8.5.56\conf\logging.properties"   org.apache.catalina.startup.Bootstrap start

 

 

 

 

Otherwise kill it.

 

 

3- Recyle IIS :

iisreset

 

4- Delete manually the 2 folders 

 

CA\DSM\Web Console\webapps\wac

CA\DSM\Web Console\webapps\AMS

 

5- Try again to apply the patch CU4
