<div><p>Connection pooling refers to the behavior where ODBC connections
|
||
|
|
are left open after the application has requested to disconnect them. Connections
|
||
|
|
that are in the pool can be reused by the same application avoiding the time
|
||
|
|
consuming operation of creating a brand new connection.</p>
|
||
|
|
<div class="section"><p>To get an application to use connection pooling support with the iSeries™ Access
|
||
|
|
ODBC driver two basic steps must be taken:</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"> <ol><li>Connection pooling support has to be enabled for the driver. To enable
|
||
|
|
this support, open ODBC Administrator, click on the Connection Pooling tab,
|
||
|
|
double-click on iSeries Access
|
||
|
|
ODBC Driver (32-bit), and switch the checkbox to indicate to pool connections
|
||
|
|
to this driver. There is also a spot on the window to fill in the amount
|
||
|
|
of time that unused connections remain in the pool. <div class="note"><span class="notetitle">Note:</span> Beginning with
|
||
|
|
the V5R3 iSeries Access
|
||
|
|
product, connection pooling support is automatically enabled for the driver.
|
||
|
|
No additional steps are needed unless you want to override the default time
|
||
|
|
(60 seconds) that unused connections remain in the pool.</div>
|
||
|
|
</li>
|
||
|
|
<li> Connection pooling support has to be enabled by the application. An
|
||
|
|
application does this by setting the SQL_ATTR_CONNECTION_POOLING environment
|
||
|
|
attribute as part of the connection process.</li>
|
||
|
|
