<div><p>Original program model (OPM) programs are not threadsafe.</p>
|
|
<div class="section"><p>You should migrate OPM programs to Integrated
|
|
Language Environment<sup>®</sup> (ILE) and make them threadsafe before a multithreaded
|
|
application calls them. User-written Java™ methods should not call OPM programs.
|
|
When it is necessary to call an OPM program in a multithreaded application,
|
|
you should start another process to run the OPM program.</p>
