Step 2: Set Database Properties for Metadata Tables

As stated earlier each i2b2 database schema has a corresponding directory that contains the data files for installing the data. Each of these directories has a file called db.properties and it needs to be updated with your environment variables.


Steps for setting database properties


Assumptions:

  • You are logged into the command line application for your environment. (Linux: Terminal or Shell and Windows: Command Prompt)
  • You have already changed your working directory to the one that is appropriate for this installation.


1. At the command prompt type the following:


Linux Command

      open db.properties


Windows Command

      db.properties



2. The db.properties file will open. Set the following properties for the DBMS at your site:


Important

When setting the database properties make sure you set the user to i2b2metadata and the project to demo.

ACT Ontology

As of 1.7.12, it is possible to load the ACT ontology instead of the demo ontology. In this case, change the project to ACT. More information can be found in the release notes.
