Error: Could not find or load main class com.ca.OpenSpaceOnPremises.TakeBackupOpenSpace

Environment

Release : 17.2

Component : CA UNIFIED SELF-SERVICE FOR SERVICE MGMT

Resolution

The script TakeBackup.bat needs to point at a valid JRE or JDK to execute. If the one in your USS Tomcat folder has been removed, then it will fail. 

The file reads (for example)

SET JAVA_HOME=C:\Program Files\CA\Self Service\OSOP\tomcat-7.0.40\jre

SET PATH=C:\Program Files\CA\Self Service\OSOP\tomcat-7.0.40\jre\bin;%PATH%

Amending this to a valid JRE path will solve the problem.
