How do I move or copy the Plato Middle Tier?
Last Updated 4 years ago

APPLICABLE TARGET: V8.6 and prior, PLATO Application Administration, United Kingdom and Australasia.

V8.6 is Deprecated: Current V10 does not have a middle tier!

  1. Advise your users of the outage.
  2. Close any running Extractors (Extract.exe) - including any that are configured to run as Windows Services.
  3. Close the Reporting Engine (ReportingEngine.exe).
  4. Open the PLATOAtlas Admin.asp page in your browser.
  5. Click the Show and Manage ISAPI settings link.
  6. Click the Switch link to the left of the "Hold Requests: Servers Running" message.

Now you are able to move the PLATO Middle Tier folder to a new location.

Note: check and replicate file access rights from the existing to the new location. Generally, the Platoatlas DCOM impersonating user needs read/write access to its middle tier. One of the most common causes of errors and problems during this process, is the restarted Platoatlas being unable to read/write files in its middle tier.

Once you have moved the PLATO Middle Tier folder to a new location you need to adjust the following:

  1. Edit the SHARE.INI file in your new Middle Tier location and adjust any INI file settings referencing the old Middle Tier location to reference the new Middle Tier location.
  2. Edit the PLATOATLAS.INI file in your platoatlas\bin folder (on your PLATOAtlas server) and adjust any INI file settings referencing the old Middle Tier location to reference the new Middle Tier location.
  3. If you have any machines using the PLATO 32-bit client, you should reinstall them from the new Middle Tier location by running the PLATOSetup.exe from the new Middle Tier location on the machine requiring the PLATO 32-bit client.
  4. Any services running the Extract.exe or ReportingEngine.exe will need to be adjusted to run these applications from the New Middle Tier location.
  5. On your PLATOAtlas intranet server, modifiy the IIS virtual directory called Reports (which is a sub virtual directory of your main PLATOAtlas virtual directory) to reference the Reports folder in your New Middle Tier folder location.

Once the move to the new Middle Tier is complete you will need to bring the system back on line:

  1. Start the Extractors (Extract.exe) - including any that are configured to run as Window Services.
  2. Start the Reporting Engine (ReportingEngine.exe).
  3. Open the PLATOAtlas Admin.asp page in your browser.
  4. Click the Show and Manage ISAPI settings link.
  5. Click the Switch link to the left of the "Hold Requests: Servers ON HOLD" message.
