Messaging Server 5.0 setup program detects a previous server instance and fails, even though ear
During the installation of Messaging Server 5.0, the setup program displays
a message stating that a previous Messaging Server instance has been detected.
The program then prompts me to upgrade the existing server instance or create
a new server instance.
<P>
If I choose the option "Create New," the setup program will create the
following directory:
<P>
msg-<I>server-name</I>-1
<P>
Because I don't want this directory to be created, I choose the other option,
"Upgrade." However, with this option, the setup program eventually displays
the following error message:
<P>
A serious problem occurred while installing the iPlanet Messaging Server
Messaging Configuration and Services. It reported the following problem:
The application command /usr/iplanet/server5/msg-alien-1/start-msg
could not be run.
Due to a serious problem the iPlanet Messaging Server installer is unable
to continue. Please examine the log file
/usr/iplanet/server5/setup/msg/iplanet-msg-install.log for more
information.
Checking the log file reveals the following entries:
<P>
NOTICE: Running Init Config.
NOTICE: Creating messaging file attributes.
NOTICE: Running Removing old sessions database.
NOTICE: Starting Messaging Configuration and Services.
ERROR:
TYPE: Application
LOCATION: UApplicationTools::RunApplicationUNIX
DETAILS: The application command
/usr/iplanet/server5/msg-alien-1/start-msg could not be run.
Is there a way to work around this problem with the setup program detecting
a previous installation?
Use the following steps to correct this problem:
<P>
<OL>
<LI>Uninstall previously installed instance(s) of Messaging Server
<P>
<LI>Remove the
/etc/msgregistry.inf
file
<P>
<LI>Run the Messaging Server 5.0 installer again
</OL>
