The Xpress Insight server accesses the database through a standard data source named com.fico.xpress.insight.db.  By default it will connect using the username insight and password insight , but you may want to change this password as an additional security measure. 
 
 -   To change the password for the Xpress Insight user, start the PostgreSQL database console by opening a command window and entering the following: %XPRESSDIR%\insight\db\pgsql\bin\psql insightdb insight   
-  Enter the command ALTER ROLE to change the password. For example, to set the password to ficoxpress enter: ALTER ROLE insight WITH PASSWORD ficoxpress;  
-  Exit the PostgreSQL database console by entering: \q  
-  Update the data source with the new password. Open the file <installdir>\insight\server\wildfly-9.0.1.Final\standalone\configuration\standalone.xml in a text editor and locate the definition of the insightdb data source, which should look similar to the following:  
   
   <xa-datasource jndi-name="java:/com.fico.xpress.insight.db" 
   pool-name="com.fico.xpress.insight.db" enabled="true" 
   use-ccm="false">
  <xa-datasource-property name="ServerName">
   localhost
  </xa-datasource-property>
  <xa-datasource-property name="PortNumber">
    5432
  </xa-datasource-property>
  <xa-datasource-property name="DatabaseName">
    insightdb
  </xa-datasource-property>
  <driver>postgresql</driver>
  <security>
     <user-name>insight</user-name>
     <password>insight</password>
  </security>
</xa-datasource>
 
-  Change the security section of the data-source definition to include the new password. For example:  
   
         <security>
         <user-name>insight</user-name>
         <password>ficoxpress</password>
      </security>
 
-   Save this file and restart the Xpress Insight Server to apply the new configuration.
