<div class="section"><h4 class="sectiontitle">Database physical file</h4><p>The following command removes

<p>The *CURRENT journal receiver is
|

|
|
the journal receiver that is attached to journal JRNA at the beginning of
|
||
|
|
the operation. The system starts removing the changes beginning with the latest
|

|
|
entry for that member in this receiver and continues to the earliest entry
|
||
|
|
for that member in this receiver.</p>
|

<p>The following command removes the

<p>The system starts removing the changes beginning with the last

to the first entry (the earliest entry) for that member on journal receiver

RCVA8.</p>
|
||
|
|
<p>Because OUTPUT(*OUTFILE) is specified, an output file with the
|
||

name MYFILE is created. The output file contains a record for each object
|
||
|
|
that the remove operation processes. See Use the apply and remove journaled

<p>If

by removing changes from the entry preceding the last E EW start of save entry.

If the last save operation was a normal save operation, the system starts
|
||
|
|
by removing changes from the entry that precedes the last E ES data area saved
|
||
|
|
entry. In the example, journaled changes are removed back to entry 1003.</p>
