<div><p>The application requester can implicitly connect to an application
|
|
server. Implicit SQL connection occurs when the application requester detects
|
|
that the first SQL statement issued for the activation group is not a CONNECT
|
|
statement with parameters.</p>
|
|
<div class="section"><p>For a distributed program, the implicit SQL connection is made
|
|
to the relational database specified on the RDB parameter. For a nondistributed
|
|
program, the implicit SQL connection is made to the local relational database.</p>
|
|
</div>
|
|
<div class="section"><p>Implicit disconnect can occur at the following times in a process:</p>
|
|
<ul><li>When the activation group ends, if commitment control is not active, activation
|
|
group level commitment control is active, or the job level commitment definition
|
|
is at a unit of work boundary. <p>If the job level commitment definition
|
|
is active and not at a unit of work boundary, SQL is placed in the exited
|
|
state.</p>
|
|
</li>
|
|
<li>If SQL is in the exited state, when the job level commitment definition
|
|
is committed or rolled back.</li>
|

<li>At the end of a job.</li>
