The below screen shots will show you the steps to install remotely the oracle idatagent via commcell console on a windows machine by pushing the agent from a commserve.
Before pushing the agent from commserve, make sure there is no firewall blocking between the commserve and windows client machine.
Please to note, as we do a snapshot based backup, mandatory we have to select MediaAgent, Filesystem agent/core and VSS Provider while installing along with the SnapProtect IDataAgents
Once you have clicked on finish, commserve will start to push the agent and will complete the installation remotely but sometime it will be failed due to reboot required on the client machine. For the same you can select “reboot if required” option while pushing the agent but i will suggest, dont select the same option if you pushing the agent to live client. So better take a downtime for your live machine and do the reboot manually and again push the agent from commserve and it should get completed without any issues.
