<H2>Configuring hosts</H2>
<P>
By performing right mouse click on the host selection table and selecting
'Configure...' menu item, you can reach the host configuration window. Here you
can modify host specific values for the selected/all hosts have been added to the table.
<UL>
<LI><P><B>Local execd spool directory</B> — The pathname of the local spool directory
for the execution host. If differs from the global spool directory this value will be used.
The specified admin user must have the right to create this directory and
to write into it.</P>
<LI><P><B>JVM library path</B> — Path to the JVM library on the qmaster and/or shadow host(s).
Be sure to enter a correct path! If you are on a 64-bit system you may
have executed the GUI installer in default Java<SUP>TM</SUP> 32-bit mode.
In that case the detected path to the library will be for a 32-bit Java<SUP>TM</SUP>
and thread will fail to start later in 64-bit mode. Leave it empty for auto detection.</P>
<LI><P><B>Additional JVM args</B> — Additional arguments to be used when starting
the JVM on qmaster and/or shadow host(s). Default is <I>-Xmx256m</I></P>
<LI><P><B>Connect user</B> — The user name that will be used to connect to the remote host.</P>
<LI><P><B>Resolve timeout</B> — A timeout value for any operation in a resolve_pool
(resolving hosts, refreshing host states, copying an installation script to remote host).
Increase the default value if you see hosts with <FONT COLOR="#ff0000">Unreachable</FONT>
state and you are sure that password-less access is working correctly for the connect user.</P>
<LI><P><B>Install timeout</B> — A timeout value for any installation task.
Increase the default value if you see that the installation tasks are
failing with a <FONT COLOR="#ff0000">Timeout</FONT> state.</P>
</UL>
<H2>Explanation of Host and Install Task States</H2>
<P>Complete lists and description of all possible states one may
encounter in this screen can be found below. The states can be
divided in to 3 categories:</P>
<H3><B>Host resolving</B></H3>
<P STYLE="margin-top: 0in">When a new host is added in the host selection screen it get
immediately state of a <FONT COLOR="#ff0000">New unknown host</FONT>
and resolving process is started. The host is marked as <FONT COLOR="#008000">Reachable</FONT>
only if we can retrieve it's architecture. All other states specify
an error. The GUI installer won't be able to perform any installation
on such host. Following table lists all possible states:</P>
