Sybase recommends that you monitor the total JVM memory being used, after you have changes to default configuration values.
From the system administration Web page, click Memory Usage. The Memory Usage page displays the current memory usage by the JVM and other caches.
For example, the Memory Usage page may show that each document store's active stripe is using a lot of memory. If you have many document stores, you may want combine the data into fewer document stores. See “Document stores”.
