<h4 class="subsubsection">8.1.6.1 Overview of Pragma Shared_Passive</h4>
<p>The entities declared in such a categorized library unit are intended to
be mapped on a virtual shared address space (file, memory,
database). When two partitions use such a library unit, they can
communicate by reading or writing the same variable in the shared
unit. This supports the conventional shared variables paradigm.
Entryless protected objects can be declared in these units, to provide
an atomic access to shared data, thus implementing a simple transaction
mechanism. When the address space is a file or a database, the user can
take advantage of the persistency features provided by these storage
nodes.
