    <p>We are trying to setup Eclipse in a shared environment, i.e., it will be installed on a server and each user connects to it using VNC. There are different reasons for sharing Eclipse, one being proper integration with ClearCase.</p> <p>We identified that Eclipse is using large amounts of memory. We are wondering whether the Eclipse(JVM?) loads each class once per user/session or whether there is any sort of sharing of objects that are already loaded into memory?</p> <p>This makes me think about a basic question in general. How many copies of a program gets loaded into memory when two or more users are accessing the host at the same time. </p> <p>Is it one per user or a single copy is shared between users?</p> <p><strong>Two questions here:</strong></p> <blockquote> <p>1) How many copies of a program gets loaded into memory when two or more users are using it at the same time?</p> <p>2) How does the above holds in the world of Java/JVM?</p> </blockquote>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
