Notice that:

• You can install the GG on only one of the RAC nodes. But make sure that this node can read all the archive logs used for any instances.

Usually, other nodes' archive log directories are NFS-mounted to this node. NFS-mounting will cause some network delay.

• The TRANLOGOPTIONS ALTARCHIVELOGDEST: here you should write down the archive logs directories. Notice that the /archive2 is NFS-mounted to racnode1

Then, at the GGS command interface, you can add this extract by this method (notice the red words)
