<p>When no RCI package is configured on a partition, such a partition can
be launched several times without any problem. When one or more RCI
packages are configured on a partition, such a partition cannot be
launched more than once. If this partition were to be launched
repeatedly, it would not be possible to decide which partition instance
should execute a remote procedure call.
</p>
<p>When a partition crashes or is stopped, one may want to restart this
partition and possibly restore its state - with Shared_Passive packages,
for instance. In such a situation, the partition is already known to
other partitions and possibly marked as a dead partition. Several
policies can be selected:
</p>

<div class="smallexample">
<pre class="smallexample">
RECONNECTION_LITERAL ::= Reject_On_Restart  |
                         Fail_Until_Restart |
                         Block_Until_Restart

REPRESENTATION_CLAUSE ::=
   <b>for</b> PARTITION_IDENTIFIER'Reconnection <b>use</b> RECONNECTION_LITERAL;

</pre></div>

<ul>
<li> When this partition is configured with the Reject_On_Restart
reconnection policy, the dead partition is kept dead and any attempt to
restart it fails. Any remote call to a subprogram located on this
partition results in a Communication_Error exception. The
Reject_On_Restart policy is the default policy.

</li><li> When this partition is configured with the Fail_Until_Restart
reconnection policy, the dead partition can be restarted. Any remote
call to a subprogram located on this partition results in an exception
Communication_Error as long as this partition has not been restarted. As
soon as the partition is restarted, remote calls to this partition are
executed normally.

</li><li> When this partition is configured with the Block_Until_Restart
reconnection policy, the dead partition partition can be restarted. Any
remote call to a subprogram located on this partition is suspended until
the partition is restarted. As soon as the partition is restarted,
remote calls to this partition are executed normally. The suspended
remote procedure calls to this partition are resumed.


</li></ul>
