<h1 class="topictitle1">The *LOCAL directory entry</h1>
|
||
|
|
<div><p>The directory entry containing *LOCAL is unique in that there is only one
|
||
|
|
such entry in the directory, and it specifies the name of the local system
|
||
|
|
database. The associated RDB name can be used in the SQL statement CONNECT
|
||
|
|
TO x (where x is the local server name) to connect to the local database.
|
||
|
|
The effect of CONNECT TO x (where x is the local server name) is equivalent
|
||
|
|
to using the SQL statement CONNECT RESET.</p>
|
||
|
|
<p>If you want to make a DRDA<sup>®</sup> connection to the local server database, such as
|
||
|
|
for program testing, there are two special RDB names that can be used for
|
||
|
|
that purpose: ME and MYSELF. An example usage would be a programmer adding
|
||
|
|
a directory entry with an RDB name of ME, with type of *IP, and with Remote
|
||
|
|
Location name of LOOPBACK. He could then, in a program, do an SQL CONNECT
|
||
|
|
TO ME and establish a sockets DRDA connection to the local system. However,
|
||
|
|
general use of these RDB names is discouraged and they are documented only
|
||
|
|
to warn that unexpected behavior can result from their use in some situations.</p>
|
||
|
|
<p> However, if you must change the name of the local RDB entry, the procedure
|
||
|
|
includes doing the remove and add operation. But there are special considerations
|
||
|
|
for removing the local entry, because that entry contains some system-wide DRDA attribute
|
||
|
|
information. If you try to remove the entry, you will get message CPA3E01
|
||
|
|
(Removing or changing *LOCAL directory entry might cause loss of configuration
|
||
|
|
data (C G)), and you will be given the opportunity to cancel (C) the operation
|
||
|
|
or continue (G). The message text goes on to tell you that the entry is used
|
||
|
|
to store configuration data entered with the <span class="cmdname">Change DDM TCP/IP Attributes
|
||
|
|
(CHGDDMTCPA)</span> command. If the *LOCAL entry is removed, configuration
|
||
|
|
data might be destroyed, and the default configuration values will be in effect.
|
||
|
|
If the default values are not satisfactory, configuration data will have to
|
||
|
|
be re-entered with the CHGDDMTCPA command. Before removing the entry, you
|
||
|
|
might want to record the values specified in the CHGDDMTCPA command so that
|
||
|
|
they can be restored after the *LOCAL entry is deleted and added with the
|
||
|
|
correct local RDB name.</p>
