Hi,

We are in the planning phase of migrating IBM messagesight to Eclipse Amlen. I have been going through the documentation in the upgrade link provided in eclipse amlen.

The steps provided it is mentioned "Uninstall IBM Watson IoT Platform Message Gateway" as step 3 , as it is not mentioned any specific command is it works with "rpm -e nodeps [package name]" ? .

Also after following these steps, do we need to any configuration to make this work in cluster setup for ex: https://www.eclipse.org/amlen/docs/Administering/ad00361_.html ?

Our current setup has 2 ETM nodes, 1 Haproxy, 1 IBM messagesight.

++ Also one more query,

In prerequisites for Upgrading from IBM Watson IoT Platform Message Gateway to Eclipse Amlen "Hardware requirements for the Eclipse Amlen server". it is mentioned as ,

Disk 1 size : 25 GB
Disk 2 (store) size : 64 GB

Ref: - https://www.eclipse.org/amlen/docs/Planning/pl00040.html
Can anyone please let me know what is "Disk 2 (store) " ?

The uninstall should use what ever method was used to install Message Gateway. If you installed Watson Iot using rpm, then uninstall it the same way

This question probably refers to install ETM clustered which requires Amlen. In that situation you should follow the documentation for ETM. Probably this link will the best:
https://www.ibm.com/docs/en/elms/elm/7.0.3?topic=guides-interactive-installation-upgrade-setup. Look at section III. Configuring Eclipse Amlen

Disk 1 is referring to the install/logging location and Disk 2) is for any data storage.

Krzysztof Kazmierczyk >> ""Disk 1 is referring to the install/logging location and Disk 2) is for any data storage.

So in this case disk 1 space is for ""/usr/share and DIsk 2 for /var, is that correct ?

As per the new and old directory path mentioned in Amlen upgrade doc,

Old Location New Location Description
/opt/ibm/imaserver /usr/share/amlen-server Server install path
/var/messagesight /var/lib/amlen-server Data/config/diagnostics for the server
/opt/ibm/imawebui /usr/share/amlen-webui WebUI install path
/var/messagesight/webui /var/lib/amlen-webui Data/config/diagnostics path for the WebUI

Where as for install it is mentioned as below command.

Please clarify how you installed MessageSite (what command you used) .

Naveen >>
We installed message sight with below commands

$ sudo rpm -ivh /opt/IBM/imaserver/IBMIoTMessageSightServer-2.0.0.2-20190222.1951.x86_64.rpm
$ sudo yum install -y openldap-servers

In that situation you should unistall MEssageSight using rpm command.
Probably you should use 
rpm -e IBMIoTMessageSightServer
rpm -e IBMIoTMessageSightWebUI

Hi Krzysztof,

I have upgrade our message sight application to Eclipse Amlen.
After installation, service are running and I am able to see the WEBUI.
But application status shows in Maintenance mode, I am unable to stop maintenance to restart it in production mode.
Can you please suggest here.

Hi Naveen,
Please have a look at this document: https://eclipse.dev/amlen/docs/Troubleshooting/tr00006_.html. Here is what it states:

There are several reasons that the Eclipse Amlen server state changes to maintenance mode:
There is a configuration error. For example:
High Availability might be configured with the wrong IP address for the local replication NIC.
The LDAP Bind DN password might be changed on the LDAP server, and therefore the Eclipse Amlen server cannot connect.
A certificate might be invalid or corrupted.
The system administrator sets the server state to Maintenance by using REST Administration APIs, or by using the Amlen WebUI. For more information changing the server state, see Changing the server state.
The store is corrupted and unrecoverable, or there are insufficient system resources to start the store. When any of these issues occur, the Eclipse Amlen server automatically changes the server state to Maintenance.
A pair of Eclipse Amlen servers in a high availability (HA) pair is incorrectly configured for cluster membership. One server in the HA pair might be configured for cluster membership but the other server in the HA pair might not be configured for cluster membership. For more information about configuring HA on cluster members, see Configuring HA.
To diagnose why the server is in maintenance mode, check the status of the server, and check the log files for possible causes. After you resolve the issue, you can change the server state from Maintenance. For more information about checking the status of the server and changing the server state, see Changing the server state.

If the store is corrupted and unrecoverable, or if there are insufficient system resources to start the store, you might need to clean the store. Cleaning the store deletes all persistent data, including messages, subscriptions, and client states. Do not clean the store unless you want to delete all persistent data on the system. For more information about cleaning the store, see Cleaning the store.

Please let us know if that helps.
