|

|
|
the query processing time limit that is compared to the estimated number of

elapsed seconds that a query must run. The time limit determines if the database
|
||
|
|
query can start.</p>
|

<p>The following are possible options:</p>
|

|

<ul><li><span class="uicontrol">No maximum (*NOMAX)</span> <p>There is no maximum number

are required to run a query. If the number of estimated elapsed seconds is
