You may need to perform the following configuration tasks, depending on the applications run in the grid.
Add another host to the grid thereby making it possible, for example, to use load balancing.
Modify Heap Size
In case the application has not defined the heap size to be used, or the default value of 2048 MB is not suitable, the heap size can be altered.
Modify Memory Threshold
When the heap usage reaches 85%, a warning is issued and the node will temporarily stop accepting requests. This is a transient state and the node will start accepting requests once memory has been recovered. If this is not a suitable threshold, it can be altered.
Enabling this setting will make the Grid forbid the embedding of HTTP content for all requesters except for those defined in a whitelist, thereby protecting against clickjacking attacks.
