If you have a persistent DB2 client connection created with
|
||
<span class="function"><a href="db2_pconnect.html" class="function">db2_pconnect()</a></span>, you may use this function to close the
|
||
connection. To avoid substantial connection performance penalties, this

function should only be used in rare cases when the persistent connection
|
||
has become unresponsive or the persistent connection will not be needed for
|

a long period of time.
