<div><p>You can use iSeries™ Navigator to compare data sets in two different
|

|
|
monitors. </p>
|

|
|
<div class="section"><p>To compare data sets in different monitors, go to <span class="menucascade"><span class="uicontrol">iSeries Navigator</span> > <span class="uicontrol"><var class="varname">system name</var></span> > <span class="uicontrol">SQL performance monitors</span></span>. Right-click
|
||
|
|
a monitor in the right pane and select <span class="uicontrol">Compare</span>.</p>
|
||
|
|
<p>On
|
||
|
|
the Compare dialog, you can specify information about the data sets that you
|
||
|
|
want to compare.</p>
|
||
|
|
<dl><dt class="dlterm">Name</dt>
|
||
|
|
<dd>The name of the monitors that you want to compare.</dd>
|
||
|
|
<dt class="dlterm">Schema mask</dt>
|
||
|
|
<dd>Select any names that you want the compare to ignore. For example, consider
|
||
|
|
the following scenario: You have an application running in a test schema
|
||
|
|
and have it optimized. Now you move it to the production schema and you want
|
||
|
|
to compare how it executes there. The statements in the compare are identical
|
||
|
|
except that the statements in the test schema use "TEST" and the statements
|
||
|
|
in the production schema use "PROD". You can use the schema mask to ignore
|
||
|
|
"TEST" in the first monitor and to ignore "PROD" in the second monitor so
|
||
|
|
that the statements in the two monitors appear identical.</dd>
|
||
|
|
<dt class="dlterm">Compare statements that ran longer than</dt>
|
||
|
|
<dd>The minimum runtime for statements to be compared.</dd>
|
||
|
|
<dt class="dlterm">Minimum percent difference</dt>
|
||
|
|
<dd>The minimum difference in key attributes of the two statements being compared
|
||
|
|
that determines if the statements are considered equal or not. For example,
|
||
|
|
if you select 25% as the minimum percent different, only matching statements
|
||
|
|
whose key attributes differ by 25% or more are returned.</dd>
|
||
|
|
</dl>
|
||
|
|
<p>When you click <span class="uicontrol">Compare</span>,
|
||
|
|
both monitors are scanned for matching statements. Any matches found will
|
||
|
|
be displayed side-by-side for comparison of key attributes of each implementation.</p>
|
||
|
|
<p>On
|
||
|
|
the Comparison output dialog, you view statements that are included in the
|
||
|
|
monitor by clicking <span class="uicontrol">Show Statements</span>. You can also run
|
||
|
|
Visual Explain by selecting a statement and clicking <span class="uicontrol">Visual Explain</span>.</p>
