[DUG]: Midas 2 and Midas 3 on the same machine.

[Stacey Verner]

We had a system that was in Delphi 4 (Midas 2)

 

App1

App2    ->    Socket Server (D4)    ->     Appserver1

App3

 

We have now upgraded to Delphi 6 (Midas 3) so any new software we write is in Delphi 6, but until the next version of our main piece of software is finished we are still running some Delphi 4 Apps.

 

So what we now have is

 

App1

App2    ->                                        -> Appserver1 (D4)

                    Socket Server (D6)

App3    ->                                         -> AppServer2 (D6)

 

 

Current if only App1 and App2 (Midas 2) are used everything runs smoothly.

If App3 (Midas 3) is used then it worke well most of the time, but sometimes AppServer2 hangs so that new connections just sit there waiting. No timeout. Also, but less often AppServer1 hangs as well. In this case once we fix up AppServer2 (kill all App3's and then Kill AppServer2) AppServer1 works again.

 

AppServer1 and Appserver2 have different GUID's but that names of the RDM's, Methods and Providers are the same.

AppServer2 is essentially AppServer1 ported to Midas 3.

AppServer1 and 2 both use a TDatabase to connect to an informix database. They don't use an existing BDE alias but they do have the same DatabaseName.

 

Is it OK to have Midas 2 and Midas 3 App servers on the same machine?

Do I need to change more than the GUID's between versions of an AppServer?

Anything else I should know?

 

Thanks
