Oracle Grid Infrastructure Home is: /u01/app/18.0.0/grid
The following nodes are part of this cluster: racnode1

WARNING !
Deinstall utility has detected that Oracle Clusterware processes are not running on the local node, 
hence entries of Real Application Cluster Databases that are being deinstalled will not be removed from Oracle Cluster Registry (OCR). 
For complete deinstallation of Real Application Cluster Databases, it is recommended to run the deinstall utility with Oracle Clusterware running.

The cluster node(s) on which the Oracle home deinstallation will be performed are:racnode1
Oracle Home selected for deinstall is: /u01/app/oracle/product/12.1.0/dbhome_1
Inventory Location where the Oracle home registered is: /u01/app/oraInventory
The following databases were selected for de-configuration : RACTEST1,RACTEST
Database unique name : RACTEST1
Storage used : ASM
Database unique name : RACTEST
