Possible Hardware Setups for Upgrading
Possible hardware setups are from one to four machines.
A four-machine setup can be used, with each installation on its own machine. More commonly, however, the two development installations share a machine. Because there is usually some traffic between these two installations during preparation, sharing a machine is convenient.
Note: If you are using Windows, you need a separate machine for each installation. Versions prior to Ingres 2.6 do not support multiple installations on one Windows machine.
A three-machine setup is the recommended minimum, as follows:
• Development (both old and new versions)
• Test
• Production
A two-machine setup is possible, as follows:
• Development (possibly including a test installation)
• Production
The two-machine setup is not recommended because the test installation shares a machine with development, so it will not mimic your production installation as closely. In addition, the more installations on a machine, the more chance for error.
A single machine setup is possible, but not recommended, since you may accidentally work in the wrong installation and damage production.
Note: There is no remote installation procedure for Ingres. The machine must have local media support (CD-ROM or tape); otherwise, you will have to copy the distribution files from wherever the CD-ROM or tape drive is situated.
