How to Manage and Check Health of Exadata Cloud Related Services - ExaCS and ExaCC

Solution

A) Please check passwordless ssh - working for the OPC / GRID / ORACLE OS Users

Login as OPC user and run following command to check passwordless ssh (Please change the GRID Home Path for the olsnodes in following command)

for node in `sudo /u01/app/19.0.0.0/grid/bin/olsnodes`; do ssh -t -t -i /home/opc/.ssh/id_rsa -o StrictHostKeyChecking=no opc@$node 'hostname -s;date'; done

Login as OPC user and Switch User to GRID user and run following command to check passwordless ssh

sudo su -
su - grid
for node in `/u01/app/19.0.0.0/grid/bin/olsnodes`; do ssh -t -t -i /home/grid/.ssh/id_rsa -o StrictHostKeyChecking=no grid@$node 'hostname -s;date'; done

Login as OPC user and Switch User to ORACLE user and run following command to check 

sudo su -
su - oracle
for node in `/u01/app/19.0.0.0/grid/bin/olsnodes`; do ssh -t -t -i /home/oracle/.ssh/id_rsa -o StrictHostKeyChecking=no oracle@$node 'hostname -s;date'; done
