The AGG_SERVICE_ACCOUNT is an i2b2 user account used to run aggregate-counting queries in i2b2. These parameters should reflect the account name and password. We recommend changing the password. 


It is also possible to change this password manually:

  1. Login using the AGG_SERVICE_ACCOUNT account on the webclient and in the top right select change password
  2. Update the hive_cell_param on using the following, where {password} is the password from step 1
update hive_cell_params set value='{password}' where param_name_cd='';

3. Restart i2b2

Cell URLs


If your cells are installed on different servers (e.g., Project Management is on a different server than the Ontology cell), you will need to make this change because the hostnames cannot be autodetected.
