Single Node Installations
Single-node installations provide the simplest installation and permit quick starts. For most development purposes single-node installations are acceptable and the best choice.
For single-node installations, all the required software is installed on one machine, port numbers are unchanged, and TIBCO MDM is started in seeder mode with no external server.
If you are going to perform a single-node installation, consider using the embedded PostgreSQL database so you can use the simplified installer without separate database installs.
The default setup works well for small datasets (for example, under 50K). The default setup also works for larger datasets if you import or export data in chunks of 50K. For larger datasets, database tuning may be required.
User testing (such as User Acceptance Testing) generally requires a separate environment.
