Windows: –

- Stop Tomcat by the stop icon
- Navigate to Default Tomcat cache Directory: <Default BI Install Directory>\Tomcat\work\Catalina
- Delete the Localhost directory
- Start Tomcat
- Launch the CMC or BI Launch Pad from the browser, this step will take a while because the localhost folder will be re-created, and all content repopulated.
- As soon as the content has been fully populated – the login page will display.

- Navigate to the following folder location: Install Path/sap_bobj
- Execute the following script to stop the running tomcat process: ./tomcatshutdown.sh
- Navigate to the following folder location: Install Path /sap_bobj/tomcat/work/
- Delete the localhost directory
- Navigate to the following folder location: Install Path /sap_bobj directory.
