Summary

• SAP NW AS Java can be configured and administered using the configuration tool, Visual Administrator, or NetWeaver Administrator tool.

• The configuration tool is used to set up Java memory parameters. It directly connects to the database; therefore, the database needs to be up before you can use the tool.

• Visual Administrator is a graphical tool used for stopping the cluster elements and managing Java managers, services, and libraries.

• Visual Administrator connects to the Java engine; therefore, the system needs to be up before you can use the tool.

• NWA is the most current browser-centric tool delivered by SAP for configuring and administering the NW AS Java system, and it replaces Visual Administrator.
