It's quite simple. It's an easy job that almost doesn't require any technical foundation, just repeating some meaningless routine tasks every day.
I've been working like this for more than half a year, until recently, a client company originally handled by Miyasato proposed to transfer the entire mainframe system to their company for internal maintenance.
After losing this part of the workload, Miyasato, of course, quickly got assigned to other business——
Responsible for the system of a small appliance company operating on a large computer.
After taking on this business, the real headache for Miyasato Takeru began.
The company producing small appliances often has system issues, frequent crashes.
Generally speaking, the system of commercial large computers is usually quite stable.
According to the systems previously managed by Miyasato, running a job leading to a crash might happen just a few times a year, or not at all.
