Rushing on the road, advancing to Shandong

After several months of efforts, the opportunity to come to Beijing, for a new work environment, and a new starting point. It is unclear when the unknown is with Oracle, but at this time has been "chopping constantly disorderly", become a part of life, devotion.

July 30 received the arrangement of the mission. Get ready to go. The main tasks are three:

(1), Weihai Part A data center system application adjustment;

(2), Zibo, part B data cloud Platform migration;

(3), Texas C cluster Database environment transformation.

August 1, 4:30, Blue, opened his eyes, and Beijing said "Good Morning", the road of the horn officially sounded.

A lot earlier than usual, because of the early morning road some worry, abandon the taxi ride plan, change to take the subway, because in Beijing, said bad when the traffic jam enough to delay the original arrangements and plans.

In the subway station, the sparse rare, a time to feel the space is so empty, there is a little bit of adaptation. After several transfers, all the way smoothly boarded the EMU first seat of the car, obviously more familiar than before the second-class seats more spacious (only feel that), the train has not been started, will seat back fine-tuning, closed the NAP, do not know how long, may be more than 10 minutes, feel the train has been started, the trip formally began. (said some funny, originally thought that Weihai did not have the airport, the colleague helps to book the train ticket, afterwards only then knew, actually flies the word will be much quicker, here sweats ... ）

Passing time along the journey, carrying a Zhang Xiaoming book, "Big Oracle Grid", the knowledge of the recent period of some unfamiliar, really two days do not see can forget the Cloud nine (the essence or their knowledge of the mastery of too shallow).
