|
<div><p>This topic discusses the different connection states and ways to
|
|
change them.</p>
|
|
<div class="section"><div class="p">If an application processes a CONNECT statement and the server
|
|
name is known to the application requester and is not in the set of existing
|
|
connections of the activation group, then: <ul><li>The current connection is placed in the dormant state and held state.</li>
|
|
<li>The server name is added to the set of connections and the new connection
|
|
is placed in the current and held state.</li>
|
|
</ul>
|
|
</div>
|
|
<p> If the server name is already in the set of existing connections
|
|
of the activation group, an error occurs.</p>
|
|
</div>
|
|
<div class="section"><p>A connection in the dormant state is placed in the current state
|
|
using the SET CONNECTION statement. When a connection is placed in the current
|
|
state, the previous current connection, if any, is placed in the dormant state.
|
|
No more than one connection in the set of existing connections of an activation
|
|
group can be current at any time. Changing the state of a connection from
|
|
current to dormant or from dormant to current has no effect on its held or
|
|
released state.</p>
|
|
</div>
|
|
<div class="section"><p>A connection is placed in the released state by the RELEASE statement.
|
|
When an activation group executes a commit operation, every released connection
|
|
of the activation group is ended. Changing the state of a connection from
|
|
held to released has no effect on its current or dormant state. Thus, a connection
|
|
in the released state can still be used until the next commit operation. There
|
|
is no way to change the state of a connection from released to held.</p>
