<h1 class="topictitle1">Apply program temporary fixes</h1>
|
|
<div><p>Beginning in i5/OS™ V5R4, you can use the Display Java™ Virtual
|
|
Machine Jobs (DSPJVMJOB) CL command to manage your JVM jobs and apply PTFs
|
|
while the system is active.</p>
|
|
<p>Many Java Program Temporary Fixes (PTFs) impact the JVM such
|
|
that, if the code is applied while a JVM job is running, applying the PTF
|
|
will cause unpredictable results. In the past, the application of some Java PTFs
|
|
has been delayed until an initial program load (IPL) could be performed on
|
|
the system to ensure that there would be no JVM jobs running on the system.
|
|
Many users, however, found this to be inconvenient. A JVM pre-condition was
|
|
added so that many of those delayed PTFs could be applied immediately, <em>if
|
|
no JVMs are active on the system</em>. The DSPJVMJOB command allows you to
|
|
see which jobs have JVMs running in them. With this information, you can end
|
|
the jobs containing active JVMs appropriately before applying PTFs, instead
|
|
of waiting for an IPL for the PTFs to be applied.</p>
|
|
<p>To learn more about the DSPJVMJOB command, see <a href="../cl/dspjvmjob.htm">Display Java Virtual
|
|
Machine Jobs</a> in the CL topic.</p>
