Easier i2b2 Install

The i2b2 server can now be installed in three or four steps:

  1. (Optional) Build the war from source. Run in the edu.harvard.i2b2.server-common folder:
          ant clean dist war
  2. Copy the i2b2.war from the dist folder (or the binary release zip file) to /opt/wildfly-VERSION-Final/standalone/deployments/ folder.
  3. Run the data build for all the cell (PM, HIVE, ONT and CRC) . In the Hive there is a new table called HIVE_CELL_PARAM which contains all the previous XML and properties file.
  4. Modify the *-ds.xml in the deployment folder to point to the database

NOTE: If you are an existing user and have previously changed the properties files, you will need to modify the corresponding parameters in HIVE_CELL_PARAMusing a pre-built war file instead of having to build it from source, or the war file can be built from source much more easily. More information is in the updated Installation Guide. The properties files are now stored in the database.



1) Set Project Params (PM_PROJECT_PARAM)

REDCP_TOKEN REDCAP_TOKEN_PID_{pid}(7B42348B7C51123432048B51EAA)


  • Get the pid value from the Redcap project url. Set the pid parameter name to this value

  • Get the API Key from Redcap.  Logon to Redcap, and on the right side under applications click API. 
  •  Then, select Generate token, and use this token for the value for the
  • parameter.

Optional, Defaults to \REDCAP\
What This is the key for the root of the REDCap ontology is.


Optional, Defaults to tree
How This is how the ontology will be created

tree - All enumerated values, Yes/No will be children on the ontology

The only exception is items with checkbox, which will always be a popup

                                          SQL server:              
                                          exec RUNTOTALNUM

                                          select RUNTOTALNUM('observation_fact','public')
                                      -- (replace 'public' by the schema name for the fact table)
                                      -- I
f using a schema other than public for metadata, you might need to run "set search_path to 'i2b2metadata','public' " first as well
