Following instruction can be used to clone Oracle GI Restart from working Oracle Linux Server to another new server. This method can save a lot of time in installing the GI Software, oracle database software and then applying PSU patch to every new server.
Assumption: You already have the OS template or server with Oracle Linux 6.4, Oracle Grid Infrastructure(GI) and Database software 11gR2 installed. Also, the binaries are already been copied to target server.
Assumption: You already have the OS template or server with Oracle Linux 6.4, Oracle Grid Infrastructure(GI) and Database software 11gR2 installed. Also, the binaries are already been copied to target server.
These instructions can also be used for environments created using VDI or OVM template with Oracle software already installed.
