<div><p>When an external function associated with an ILE external program
|
|
or service program is created, an attempt is made to save the function's attributes
|
|
in the associated program or service program object.</p>
|
|
<div class="section"><p>If the *PGM or *SRVPGM object is saved and then restored to this
|
|
or another system, the catalogs are automatically updated with those attributes.
|
|
If the function's attribute cannot be saved, then the catalogs will not be
|
|
automatically updated and the user must create the external function on the
|
|
new system. The attributes can be saved for external functions subject to
|
|
the following restrictions:</p>
|
|
<ul><li>The external program library must not be QSYS or QSYS2.</li>
|
|
<li>The external program must exist when the CREATE FUNCTION statement is
|
|
issued.</li>
|
|
<li>The external program must be an ILE *PGM or *SRVPGM object.</li>
|
|
<li>The external program or service program must contain at least one SQL
|
|
statement.</li>
|
|
</ul>
|
|
<p>If the program object cannot be updated, the function will still be
|
|
created.</p>
