<h1 class="topictitle1">Move data between <span class="keyword">iSeries server</span>s
|
|
using copy file commands</h1>
|
|
<div><p>Another way to move data from one <span class="keyword">iSeries™ server</span> to
|
|
another is to copy the data using the copy file commands with DDM.</p>
|
|
<div class="section"> <p>You can use the <span class="cmdname">Copy File (CPYF)</span>, <span class="cmdname">Copy
|
|
Source File (CPYSRCF)</span>, and <span class="cmdname">Copy From Query File (CPYFRMQRYF)</span> commands
|
|
to copy data between files on source and application servers (ASs). You can
|
|
copy local relational database or device files from (or to) remote database
|
|
files, and remote files can also be copied to remote files.</p>
|
|
<p>For example,
|
|
if a dealership closes, the distributed relational database administrator
|
|
can copy the client and inventory tables from the remote server to the local
|
|
regional server. The administrator needs a properly authorized user profile
|
|
on the application server (AS) to access and copy the tables and must create
|
|
a DDM file on the application requester (AR) for each table or file that is
|
|
copied. The following example shows the command the database administrator
|
|
would use to copy a table called INVENT in a collection called SPIFFY from
|
|
a server with a remote location name of KC105 to a regional center server
|
|
called KC000. A DDM file called INCOPY in a library called TEST on the application
|
|
requester (AR) KC000 is used for the file access. These commands are run on
|
|
the KC000 server: </p>
|
|
<pre>CRTDDMF FILE(TEST/INCOPY) RMTFILE(SPIFFY/INVENT)
|
|
RMTLOCNAME(KC105)
|
|
CPYF FROMFILE(TEST/INCOPY) TOFILE(TEST/INVENTDDM)
|
|
MBROPT(*ADD)</pre>
|
|
<p>In this example, the administrator runs the
|
|
commands on the KC000 server. If the administrator is not on the KC000 server,
|
|
then pass-through must be used to run these commands on the KC000 server.
|
|
The <span class="cmdname">Submit Remote Command (SBMRMTCMD)</span> command cannot be
|
|
used to run the above commands because the <span class="keyword">iSeries server</span> cannot
|
|
be an application requester (AR) and an application server (AS) for the same
|
|
job.</p>
|
|
<p>Consider the following items when using this command with DDM:
|
|
</p>
|
|
<ul><li>A DDM file can be specified on the FROMFILE and the TOFILE parameters
|
|
for the <span class="cmdname">Copy File (CPYF)</span> command and <span class="cmdname">Copy Source
|
|
File (CPYSRCF)</span> commands. <div class="note"><span class="notetitle">Note:</span> For the <span class="cmdname">Copy From Query
|
|
File (CPYFRMQRYF)</span> and <span class="cmdname">Copy from Tape (CPYFRMTAP)</span> commands,
|
|
a DDM file name can be specified only on the TOFILE parameter; for the <span class="cmdname">Copy
|
|
to Tape (CPYTOTAP)</span> command, a DDM file name can be specified only
|
|
on the FROMFILE parameter.</div>
|
|
</li>
|
|
<li>When a delete-capable file is copied to a non-delete capable file, you
|
|
must specify COMPRESS(*YES), or an error message is sent and the job ends.</li>
|
|
<li>If the remote file name on a DDM file specifies a member name, the member
|
|
name specified for that file on the <span class="cmdname">Copy File (CPYF)</span> command
|
|
must be the same as the member name on the remote file name on the DDM file.
|
|
In addition, the <span class="cmdname">Override with Database File (OVRDBF)</span> command
|
|
cannot specify a member name that is different from the member name on the
|
|
remote file name on the DDM file.</li>
|
|
<li>If a DDM file does not specify a member name and if the <span class="cmdname">Override
|
|
with Database File (OVRDBF)</span> command specifies a member name for
|
|
the file, the <span class="cmdname">Copy File (CPYF)</span> command uses the member
|
|
name specified on the <span class="cmdname">OVRDBF</span> command.</li>
|
|
<li>If the TOFILE parameter is a DDM file that refers to a file
|
|
that does not exist, <span class="cmdname">CPYF</span> creates the file. Keep the following
|
|
special considerations for remote files created with the <span class="cmdname">Copy File
|
|
(CPYF)</span> command in mind: <ul><li>The user profile for the target DDM job must be authorized to the <span class="cmdname">Create
|
|
Physical File (CRTPF)</span> command on the application server (AS).</li>
|
|
<li>For an <span class="keyword">iSeries</span> target,
|
|
the TOFILE parameter has all the attributes of the FROMFILE parameter except
|
|
those described in the <a href="../dm/rbal3kickoff.htm">File
|
|
management</a> topic.</li>
|
|
</ul>
|
|
</li>
|
|
<li>When using TCP/IP, the second element of the RMTLOCNAME parameter of the <span class="cmdname">Create
|
|
Distributed Data Management File (CRTDDMF)</span> command must be *IP.</li>
|
|
</ul>
