<div class="block">Thrown when attempting to use a Database handle that was forcibly closed by
|
|
replication. This exception only occurs in a replicated environment and
|
|
normally only occurs on a Replica node. In the case of a DPL schema upgrade
|
|
where an entity class or secondary key is renamed, it may also occur on a
|
|
Master node, as described below.
|
|
|
|
<p>This exception occurs when accessing a database or store and one of the
|
|
following methods was recently executed on the master node and then replayed
|
|
on a replica node:
|
|
<a href="../../../../com/sleepycat/je/Environment.html#truncateDatabase-com.sleepycat.je.Transaction-java.lang.String-boolean-"><code>truncateDatabase</code></a>,
|
|
<a href="../../../../com/sleepycat/je/Environment.html#removeDatabase-com.sleepycat.je.Transaction-java.lang.String-"><code>removeDatabase</code></a> and
|
|
<a href="../../../../com/sleepycat/je/Environment.html#renameDatabase-com.sleepycat.je.Transaction-java.lang.String-java.lang.String-"><code>renameDatabase</code></a>.</p>
|
|
|
|
<p>When using the <a href="../../../../com/sleepycat/persist/package-summary.html"><code>DPL</code></a>, this occurs only in two
|
|
circumstances:</p>
|
|
<ol>
|
|
<li>This exception is thrown on a Replica node when the <a href="../../../../com/sleepycat/persist/EntityStore.html#truncateClass-java.lang.Class-"><code>truncateClass</code></a> method has
|
|
been called on the Master node.</li>
|
|
<li>This exception is thrown on a Replica or Master node when an entity
|
|
class or secondary key has been renamed and the application has been
|
|
upgraded. See
|
|
<a href="../../persist/evolve/package-summary.html#repUpgrade">Upgrading
|
|
a Replication Group</a>.</li>
|
|
</ol>
|
|
|
|
<p>When this exception occurs, the application must close any open cursors
|
|
and abort any open transactions that are using the database or store, and
|
|
then close the database or store handle. If the application wishes, it may
|
|
then reopen the database (if it still exists) or store.</p>
|
|
|
|
<p>Some applications may wish to coordinate the Master and Replica sites to
|
|
prevent a Replica from accessing a database that is being truncated, removed
|
|
or renamed, and thereby prevent this exception. Such coordination is not
|
|
directly supported by JE. The DatabasePreemptedException is provided to
|
|
allow an application to handle database truncation, removal and renaming
|
|
without such coordination between nodes.</p>
