<div><p>The primary strategy for capturing and reporting error information
|
||
|
|
for the distributed database function is called <dfn class="term">first failure
|
||
|
|
data capture (FFDC)</dfn>.</p>
|
||
|
|
<div class="section"><p>The purpose of FFDC support is to provide accurate information
|
||
|
|
about errors detected in the DDM components of the <span class="keyword">i5/OS™</span> system
|
||
|
|
from which an APAR (Authorized Program Analysis Report) can be created. By
|
||
|
|
means of this function, key structures and the DDM data stream are automatically
|
||
|
|
dumped to a spool file. The first 1024 bytes of the error information are
|
||
|
|
also logged in the system error log. This automatic dumping of error information
|
||
|
|
about the first occurrence of an error means that the failure must not need
|
||
|
|
to be recreated to be reported by the customer. FFDC is active in both the
|
||
|
|
application requester and application server functions of the <span class="keyword">i5/OS</span> DDM
|
||
|
|
component. However, for the FFDC data to be logged, the system value QSFWERRLOG
|
||
|
|
must be set to *LOG. </p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> Not all negative SQLCODEs are dumped; only

those that can be used to produce an APAR are dumped. For more information
