Log in to a compute node as the Oracle software owner, launch SQL*Plus, connect as SYSDBA , and execute the
following create pfile command. Repeat for each database on our Exadata Database Machine:
[oracle@cm01dbm01 ~]$ sqlplus / as sysdba

Stop Your Oracle Databases, ClusterWare Resources, and Drop ASM Disk Groups
Next, stop each of your Exadata databases using srvctl stop database . Log in as the Oracle software owner and run
the following command:
[oracle@cm01dbm01 ~]$ srvctl stop database -d visy
[oracle@cm01dbm01 ~]$ srvctl stop database -d visx
[oracle@cm01dbm01 ~]$ srvctl stop database -d dwprd
[oracle@cm01dbm01 ~]$
When complete, log in to a compute node as the Grid Infrastructure owner and drop your ASM disk groups:
SQL> select name from v$asm_diskgroup;
NAME
------------------------------
DATA_CM01
DBFS_DG
RECO_CM01
SDATA_CM01
SRECO_CM01
