<h1 class="topictitle1">Consistency token</h1>
|
||
|
|
<div><p>The program and its associated SQL package contain a consistency
|
||
|
|
token that is checked when a call is made to the SQL package.</p>
|
||
|
|
<div class="section"><p>The consistency tokens must match or the package
|
||
|
|
cannot be used. It is possible for the program and SQL package to appear to
|
||
|
|
be uncoordinated. Assume the program is on the <span class="keyword">iSeries™</span> system
|
||
|
|
and the application server is another <span class="keyword">iSeries</span> system.
|
||
|
|
The program is running in session A and it is recreated in session B (where
|
||
|
|
the SQL package is also recreated). The next call to the program in session
|
||
|
|
A might result in a consistency token error. To avoid locating the SQL package
|
||
|
|
on each call, SQL maintains a list of addresses for SQL packages that are
|
||
|
|
used by each session. When session B re-creates the SQL package, the old SQL
|
||
|
|
package is moved to the QRPLOBJ library. The address to the SQL package in
|
||
|
|
session A is still valid. (This situation can be avoided by creating the program
|
||
|
|
and SQL package from the session that is running the program, or by submitting
|
||
|
|
a remote command to delete the old SQL package before creating the program.)</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>To use the new SQL package, you should end the connection with
|
||
|
|
the remote system. You can either sign off the session and then sign on again,
|
||
|
|
or you can use the interactive SQL (STRSQL) command to issue a DISCONNECT
|
||
|
|
for unprotected network connections or a RELEASE followed by a COMMIT for
|
||
|
|
protected connections. RCLDDMCNV should then be used to end the network connections.
|
||
|
|
Call the program again.</p>
