<div><p>This topic outlines the restrictions that apply to an established
|
||
|
|
and enabled referential constraint in check pending.</p>
|
||
|
|
<p>A dependent file in a constraint relationship that is marked as check pending
|
||
|
|
cannot have any file input/output (I/O) operations performed on it. You must
|
||
|
|
correct the file mismatches between the dependent and parent files. Also,
|
||
|
|
you must take the relationship out of check pending before the system allows
|
||
|
|
any I/O operations. The system does not allow records to be read from such
|
||
|
|
a file because the user or application might not be aware of the check pending
|
||
|
|
status and the constraint violation.</p>
|
||
|
|
<p>To perform I/O operations on a dependent file with an enabled referential
|
||
|
|
constraint in check pending, you can first disable the constraint and then
|
||
|
|
perform the I/O operations that you want.</p>
