Hi,

you can set those Java VM parameter using config tool.

You maintain the VM Settings by selecting a dispatcher or server node of the instance in the window of the left of the Config Tool. The VM parameters with their settings

then appear in the window on the right. The runtime

parameters are on the General

tab page. See also the figure .VM Settings.. The Bootstrap tab

page contains the

settings for the start process. The parameter Java Home sets where in the file system

the SDK resides. You can also change the parameter Max heap size with the arrow

keys. Max heap size is referred to in SAP Notes or the Sun

documentation as .-Xmx..

The other Java parameters illustrated in the figure .VM Settings. are familiar from

the previous section. You can edit or delete them in the Config Tool. You can also

add additional parameters, such as .-XX:MaxPermSize=128m. here. After you

have completed your maintenance work, you must save the settings in the database

by choosing Apply changes. When the SAP Web AS Java instance is restarted, it

is started with the new values.
