<P>
This information describes the DbMemoryException class and how it
is used by the various Db* classes.</p> <p>
A DbMemoryException is thrown when there is insufficient memory to
complete an operation, and there is the possibility of recovering.
An example is during a <A HREF="../../../com/sleepycat/db/Db.html#get(com.sleepycat.db.DbTxn, com.sleepycat.db.Dbt, com.sleepycat.db.Dbt, int)"><CODE>Db.get</CODE></A> or
<A HREF="../../../com/sleepycat/db/Dbc.html#get(com.sleepycat.db.Dbt, com.sleepycat.db.Dbt, int)"><CODE>Dbc.get</CODE></A> operation with the <A HREF="../../../com/sleepycat/db/Dbt.html" title="class in com.sleepycat.db"><CODE>Dbt</CODE></A> flags set to <A HREF="../../../com/sleepycat/db/Db.html#DB_DBT_USERMEM"><CODE>Db.DB_DBT_USERMEM</CODE></A>.</p> <p>
In a Java Virtual Machine, there are usually separate heaps for
memory allocated by native code and for objects allocated in Java
code. If the Java heap is exhausted, the JVM will throw an
OutOfMemoryError, so you may see that exception rather than
DbMemoryException.</p>
