<h1 class="topictitle1">Compare journal images</h1>
|
|||
|
|
<div><p>Use the Compare Journal Images (CMPJRNIMG) command to compare and
|
|||
|
|
list the differences between the before-image of a record and the after-image
|
|||
|
|
of that record, or the after-image of a record with the previous after-image
|
|||
|
|
of that record.</p>
|
|||
|
|
<div class="note"><span class="notetitle">Note:</span> If you are using maximum receiver-size option RCVSIZOPT(*MAXOPT3) and
|
|||
|
|
your entry sequence numbers exceed 9 999 999 999, specify the
|
|||
|
|
FROMENTLRG and TOENTLRG parameters when you use the CMPJRNIMG command.</div>
|
|||
|
|
<p><img src="./delta.gif" alt="Start of change" />You can only use the CMPJRNIMG command for journaled
|
|||
|
|
physical database files. You cannot use the CMPJRNIMG command for journal
|
|||
|
|
entries that have minimized entry-specific data. If you specified the minimized
|
|||
|
|
entry-specific data (MINENTDTA(*FILE) or MINENTDTA(*FLDBDY) parameter on the
|
|||
|
|
Create Journal (CRTJRN) or Change Journal (CHGJRN) commands, the journal entries
|
|||
|
|
might have minimized entry-specific data, preventing you from being able to
|
|||
|
|
compare journaled images.<img src="./deltaend.gif" alt="End of change" /></p>
|
|||
|
|
<p>If the journaled files have null-capable fields, the null value indicators
|
|||
|
|
corresponding to the fields in the before-image of the record are compared
|
|||
|
|
with the null value indicators corresponding to the fields in the after-image
|
|||
|
|
of the record. A field-by-field basis compare does this.</p>
|
|||
|
|
<p>The printed output from the CMPJRNIMG command shows the before-images and
|
|||
|
|
after-images of a record followed by a line that indicates (with asterisks)
|
|||
|
|
the specific change in the record on a character-by-character basis. If you
|
|||
|
|
compare the after-images, the output shows the previous after-image of the
|
|||
|
|
record and the current after-image of the record, followed by a line indicating
|
|||
|
|
the changes.</p>
|
|||
|
|
<p>If you use this command to compare journal images for a file that contains
|
|||
|
|
any fields of data type BLOB (binary large object), CLOB (character large
|
|||
|
|
object), or DBCLOB (double-byte character large object), these fields are
|
|||
|
|
not included in the comparison. All other fields in the file are compared.</p>
