<h1 class="topictitle1">Specify a relational database alias name</h1>
|
||
|
|
<div><p>The next example shows the addition of a directory entry that specifies
|
||
|
|
an RDB alias name. This allows networks that have relational databases of
|
||
|
|
the same name to uniquely identify each in a Distributed
|
||
|
|
Relational Database Architecture™ (DRDA<sup>®</sup>) environment. When an entry using
|
||
|
|
an alias has been added to the RDB directory, the entry is identified by its
|
||
|
|
alias name. To display or delete the entry, you must specify the alias name.</p>
|
||
|
|
<p>The following display has RDBALS specified as the relational database alias
|
||
|
|
name.</p>

<div class="section"><p>When you add an entry for an alias using <span class="cmdname">WRKRDBDIRE</span> and
|

option 1, you should first put the real RDB name in the <strong>Entry</strong> field,
|
||
|
|
and press Enter. Then, after filling in the other fields including the alias
|
||
|
|
name in the <strong>Relational database alias</strong> field, you will see the alias
|
||
|
|
name replace the real RDB name in the <strong>Entry</strong> field of the list of RDB
|

entries. Note that you must change <strong>Type</strong> for the remote location name

from *SNA to *IP.</p>

<div class="section"><p>When removing a relational database entry with the <span class="cmdname">Remove
|

|
Relational Database Directory Entry (RMVRDBDIRE)</span> command, the alias
|
||
|
|
name, rather than the real relational database name, is used
|
||
|
|
to specify which entry to remove.</p>
|
||
|
|
<p>If you identify a remote database
|
||
|
|
by an alias, you cannot also refer to it by its real name in the same directory.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>Note that instead of specifying MP311.spiffy.com for the <span class="cmdname">RMTLOCNAME</span>,
|
||
|
|
you could have specified the IP address (for example, '9.5.25.176'). For IP
|
||
|
|
connections to another <span class="keyword">iSeries™ server</span>,
|
||
|
|
leave the PORT parameter value set at the default, *DRDA, unless you need
|
||
|
|
to use port 447. For example, you might have port 447 configured for transmission
|
||
|
|
using IP Security Architecture (IPSec). For connections to an IBM<sup>®</sup> Universal
|
||
|
|
Database (UDB) server on some other platform, for example, you might need
|
||
|
|
to set the port to a number such as 50000. Refer to the product documentation
|
||
|
|
for the server you are using. If you have a valid service name defined for
|
||
|
|
a DRDA port
|
||
|
|
at a certain location, you can also use that instead of a number. However,
|
||
|
|
on iSeries,
|
||
|
|
*DRDA is preferred to the use of the 'drda' service name. </p>
