Purpose
The purpose of writing this blog is to provide screen by screen procedure of the sapjvm patch update using the SUM (Software Update Manager) tool.
SAP has now replaced all the deployment tools for java based systems with one standard tool which is SUM to update the patches.

E:\usr\sap\<SID>\SUM>STARTUP.BAT jvm6
3. Connect to the SUM tool for your respective system - java or dual by using the URLs in the above screenshot of startup.bat script execution. If ssl is not configured, use http with port 1128
