<h1 class="topictitle1">Variable-length portion of the journal entry</h1>
|
||
|
|
<div><p>Provides the layouts of the variable-length portion of the journal
|
||
|
|
entries.</p>
|
||
|
|
<p>For output formats *TYPE1 and *TYPE2, the variable length portion of the
|
||
|
|
journal entry includes just the <span class="uicontrol">Entry-specific data</span> field.
|
||
|
|
The contents of the Entry-specific data field depends on the journal entry
|
||
|
|
code and entry type. For the layout of the output format *TYPEPTR or *JRNENTFMT,
|
||
|
|
see the QjoRetrieveJournalEntries API. For all other output formats, the variable-length
|
||
|
|
portion of the converted journal entry potentially has two fields:</p>
|
||
|
|
<ul><li>Null value indicators</li>
|
||
|
|
<li>Entry-specific data</li>
|
||
|
|
</ul>
|
||
|
|
<p>The Null Value Indicators field, contains relevant information only for
|
||
|
|
entries with journal code R. Null value indicators are present in journal
|
||
|
|
entries for record level operations as follows:</p>
|
||
|
|
<ul><li>The corresponding physical file has null capable fields.</li>
|
||
|
|
<li>The record image has been minimized in the entry specific data.</li>
|
||
|
|
</ul>
|
||
|
|
<p>Otherwise, it contains blanks. If the record image has not been minimized
|
||
|
|
in the entry specific data, the Null Value Indicators field is a character
|
||
|
|
string with one character for each field in the physical file that has record
|
||
|
|
images appearing in the journal. Each character has the following interpretation:</p>
|
||
|
|
<ul><li>0 = corresponding field in the record is not NULL.</li>
|
||
|
|
<li>1 = corresponding field in the record is NULL.</li>
|
||
|
|
</ul>
|
||
|
|
<p>If the record image was minimized on field boundaries (MINENTDTA(*FLDBDY),
|
||
|
|
and it has been formatted when reading (FMTMINDTA(*YES)) then each character
|
||
|
|
has the following interpretation:</p>
|
||
|
|
<ul><li>0 = The corresponding field was recorded and is not NULL.</li>
|
||
|
|
<li>1 = The corresponding field was recorded and is NULL.</li>
|
||
|
|
<li>9 = The corresponding field was not recorded and it's default value was
|
||
|
|
returned. </li>
|
||
|
|
</ul>
|
||
|
|
<div class="section"><h4 class="sectiontitle">System-supplied output files</h4><p>The following system-supplied
|
||
|
|
output files define the Null Value Indicators and Entry-Specific Data fields
|
||
|
|
as variable-length character fields:</p>
|
||
|
|
<ul><li>QSYS/QADSPJR3</li>
|
||
|
|
<li>QSYS/QADSPJR4</li>
|
||
|
|
<li>QSYS/QADSPJR5</li>
|
||
|
|
</ul>
|
||
|
|
<p>For additional details regarding the *TYPE3, *TYPE4, and *TYPE5 formats
|
||
|
|
and the exact layout of these two fields, see the following commands:</p>
|
||
|
|
<ul><li>Display Journal (DSPJRN)</li>
|
||
|
|
<li>Receive Journal Entry (RCVJRNE)</li>
|
||
|
|
<li>Retrieve journal entry (RTVJRNE)</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Layouts for journal entry types</h4><p>Use the Journal
|
||
|
|
entry information finder to find the layout for the variable-length portion
|
||
|
|
of the journal entry. Some one journal entry types are described in other
|
||
|
|
places than this topic. The Journal entry information finder indicates those
|
||
|
|
journal entries.</p>
|
||
|
|
<p>Some journal entry types are documented in QSYSINC
|
||
|
|
library includes, as indicated in the Journal code finder. Some entry types
|
||
|
|
do not have entry-specific data.</p>
|
||
|
|
<p>These layouts include specific values
|
||
|
|
for fields in the fixed-length portion of the entry and the fields in the
|
||
|
|
entry-specific portion of the entry. The offsets show the relative offset
|
||
|
|
within the Entry-specific data field. The beginning position of the Entry-specific
|
||
|
|
data field depends on the format type that you specify. You can also use the
|
||
|
|
Journal entry information finder to see these layouts.</p>
