Required Installations for Upgrading
For a safe and orderly upgrade, at least four OpenROAD installations are needed:
• Original version of the production installation
• Original version of the development installation
• Installation for testing the upgrade
• New version of the development installation for preparing and testing applications
If possible, keep the installations away from the production machine. You may temporarily need additional hardware to accommodate the required installations during the upgrade.
Possible Hardware Setups for Upgrading
A four-machine setup can be used, with each installation on its own machine. More commonly, however, the two development installations will share a machine. Because there is usually some traffic between these two installations during preparation, sharing a machine is convenient.
The OpenROAD 5.1 and OpenROAD 6.0 Development and Runtime features can reside on the same machine when installed into separate Ingres instances.
It is possible to deploy an OpenROAD 5.1 and OpenROAD 6.0 eClient runtime on the same machine. Configure each eClient application to select which version of the eClient runtime to use.
The OpenROAD Server for OpenROAD 5.1 and OpenROAD 6.0 needs environment variables that are set at the Windows system level. This means that you may install only one instance of the OpenROAD Server per machine.
Note: There is no remote installation procedure for OpenROAD. The machine must have local media support; otherwise, you will need to copy the distribution files from wherever they were installed.
