SugarDaddy blogs Welcome to BIT320: Databases and Information | MySmartChannels in which he analyzes the database access architecture we are using in class. Tom Campion provides comments.
It's a nice analysis, and I encourage you to read it. He raises the point that if linux4 (where you initially ssh to) goes down, we lose access to linux2 (where the database is).
Based on what the class has experienced, this is true. However, it is possible to connect directly to the Oracle database from your PC if you have the Oracle client access software. I've chosen not to use this route because it would force us to properly configure each PC, a daunting task. With the linux4-as-intermediary solution, we only have to configure linux4 to connect to Oracle.
