It is my understanding that you can keep the old workspace when upgrading to the new CICS Explorer v5.1. Is that correct? We have users on v18.104.22.168 who are upgrading to v5.1 and appear to then have issues with the connections. When keeping the existing connections file, we have experienced either an IZE0106E Connect failed with error "Unexpected end of file from server (SYSH)" or an IZE0106E Connect failed with Service unavailable (SYSH) error message.
We have found, so far, that by deleting the workspace, and starting with a new connections file, there are no issues. Does anyone have any direction regarding the workspace with the upgrade? Or any experience with these errors?

Sorry you are experiencing these issues. It's related to updates we made in version 5.1 of the explorer which has tightened security up. The Unexpected end of file exception is symptomatic of accessing a port which is either not enabled or is an SSL port. If you access an SSL port without your client indicating that it is SSL, the server doesn't actually give you the clue that it is SSL and behaves like the port is not enabled. This is because you don't want to give clues back if someone is trying to hack into your system. The old Explorer used trial and error to work out if the port was SSL which is something we have now stopped. The net effect is that some of your old connections in your client workspace may now show themselves as being non-SSL when they should be SSL. Your users should be able to edit the connection information and change the SSL setting.
The other exception you describe. "Connect failed with Service unavailable" is one I am not familiar with but would recommend editing the connection details and swapping the SSL setting.
Hopefully with this in mind both keeping the old workspace and using a new workspace with new connections file will be options available to you and your users.
If you would like further details, we have published a technote (1619304) which describes this and also covers some other security areas we have upgraded.
Hope this helps

Thank you, that helps. We'll be able to work with that, updating the connections file.
Regarding the technote, where can I find that?
