query on v$asm_diskgroup:
GROUP_NAME      STATE         TYPE      total_gb     free_gb                           
DG_CRS        'MOUNTED'     'EXTERN'      50            50                               
DG_DATA       'CONNECTED'   'EXTERN'    500            365                            
DG_FRA        'CONNECTED'   'EXTERN'     500            498                              
DG_MGMT       'MOUNTED'     'EXTERN'    100            76     

Oracle Memory:
sga_target = 15G
pga_aggregate_target = 5G

Now I'd like to add 5 new instances to my RAC database.

Based on my current configuration of memory, CPU, storage, could you please tell me which better configuration I should use to add 5 new instances to my RAC database?

Thanks in advance!
