    CRS opens and maintains as many connections as are configured in the Database Subsystem page. CRS does polling is done by executing an invalid SQL statementn the enterprise database by checking out a connection from the data source. 
    I could not find which is the exact sql statement used to test connectivity to external DBs. Does anyone know?
