For the Oracle database, set the ORACLE_HOME variable to a directory, for example, /opt/oracle/OraHome1. By default, the Control Center and CPDB data files and control files for the Oracle database reside in the directory /oracle_data1/tsprdb/DATA.
The Postgres database is bundled with the N1 Provisioning Server software package and the default location of all the data and control files is POSTGRES_HOME/data.
Because the data file and control file locations are configurable, your precise file path may vary.
