Exadata Cell - How to extract all hidden parameters? -> _cell_print_all_params=TRUE - compare 12.1.2.1.1_LINUX.X64_150316.2 vs 11.2.3.2.1_LINUX.X64_130109
‚Äč
You need to edit cellinit.ora and add following parameter _cell_print_all_params=TRUE

e.g.

echo "_cell_print_all_params=TRUE" >> /opt/oracle/cell12.1.2.1.1_LINUX.X64_150316.2/cellsrv/deploy/config/cellinit.ora
echo "_cell_print_all_params=TRUE" >> /opt/oracle/cell11.2.3.2.1_LINUX.X64_130109/cellsrv/deploy/config/cellinit.ora

* All parameters with different values was marked with bold
