Summary :
This SAP Note guides users wishing to manually update to SAP JVM 4.1. The method outlined is restricted to NetWeaver 6.40 systems. For newer versions, such as NetWeaver 7.0x, updating should be managed via the Software Update Manager. Users need to cautiously follow a series of steps that begin with creating a directory specific to the new SAP JVM version and moving through verifying the version via a manifest file, setting environment variables, and modifying instance profiles. Special instructions for IBM i users are included. The note underscores specific compatibility checks and security upgrades, like installing new JCE Policy files if needed.
