<div><p>The Verify Connection function that is located under Management
|
||
|
|
Central is different from the Verify Connection function that is located under
|
||
|
|
My Connection. This topic discuss the purpose of each function and how they
|
||
|
|
differ from each other.</p>

<div class="section"><h4 class="sectiontitle">Verify Connection from My Connection</h4><p> <span class="menucascade"><span class="uicontrol">My Connections</span> > <span class="uicontrol">Right-click a server</span> > <span class="uicontrol">Diagnostics</span> > <span class="uicontrol">Verify Connection</span></span></p>
|
||
|
|
<p>This Verify Connection function pings the different host
|
||
|
|
servers to see if they are up and running correctly and can be reached from
|
||
|
|
the PC. Since it is restricted to single system Navigator functions, it is
|
||
|
|
one of the first things you should rule out when you are troubleshooting a
|
||
|
|
Management Central connection failure. (Many Management Central functions
|
||
|
|
build on the single system functions.) After you have confirmed that the connection
|
||
|
|
to the endpoint systems, under My Connections is successful, then you can
|
||
|
|
proceed to verify the connection from Management Central.</p>

||

|
||
|
|
<p>The Verify Connection function from the Management Central
|
||
|
|
container is a diagnostic tool that checks the most common factors that can
|
||
|
|
cause a failed connection. It then displays the status of these tests. If
|
||
|
|
it reports any failures, you can obtain specific information about the failure
|
||
|
|
as well as recovery information by clicking <span class="uicontrol">Details</span>.
|
||
|
|
The following is a list of what Management Central verifies.</p>
|
||
|
|
<ul><li>The Java™ setup is correct on the Central System (This includes
|
||
|
|
verifying that certain .jar files are present, and that certain integrated
|
||
|
|
file system file and folder authorities have not been changed </li>
|
||
|
|
<li>The required files that were shipped with the operating system have not
|
||
|
|
been deleted from the Central System, are not damaged, and are being journaled</li>
|
||
|
|
<li>The TCP/IP configuration on the Central System is valid (This includes
|
||
|
|
verifying that the host name of both the Central System and the PC are in
|
||
|
|
the host tables or in the DNS as appropriate</li>
|
||
|
|
<li>That a simple Navigator connection can be made to the Central System </li>
|
||
|
|
<li>The VRM, host name, the IP address of the Central system, and the VRM
|
||
|
|
of iSeries™ Navigator </li>
|
||
|
|
<li>That the ports that Management Central uses are not in use by another
|
||
|
|
application on the central system </li>
|
||
|
|
<li>That on the central system, the user profiles that are needed to run Management
|
||
|
|
Central have not been deleted, or disabled and that they have valid, unexpired
|
||
|
|
passwords. </li>
|
||
|
|
<li>That if SSL is being used on the central system, it is configured correctly
|
||
|
|
and that both the PC and central system are using SSL. </li>
|
||
|
|
<li>That the central system isn't marked as a "secondary system" in an Management
|
||
|
|
Central High Availability environment (Secondary systems cannot be used as
|
||
|
|
central systems.)</li>
|
||
|
|
<li>That the Management Central servers are up and running on the central
|
||
|
|
system </li>
|
||
|
|
<li>It reports what types of authentication are supported on the central system</li>
|
||
|
|
</ul>

<div class="note"><span class="notetitle">Note:</span> <p>iSeries Navigator
|
||
|
|
uses the Java toolbox code on the client side (PC) to start the
|
||
|
|
Management Central Verify Connection function. If the toolbox code is not
|
||
|
|
working correctly then the Verify Connection function will not start. If the Java Virtual
|
||
|
|
Machine (JVM) or the toolbox code on the server side is not working correctly,
|
||
|
|
the Verify Connection function will work until the last few checks. The JVM
|
||
|
|
must start before these last few checks can be performed.</p>
