Yesterday to Anhui Susong a customer there to maintain the experience and lessons
The client's database server would have been good, and I was able to demonstrate to others how to install Oracle clients, install Oracle clients on the server, and halfway through the installation I suddenly felt I had found a great error: Oracle server could no longer install Oracle clients,
I quit but it's too late: fee management system can not connect to the database, PB can not connect to the database, DBA Studio can not connect to the database.
Oh, my God!!! It's going to be a big problem. Data is not backed up. Customers can't surf the internet.
I had a cold sweat and wanted to call my manager right away. It happened that the manager called. I immediately told him the situation, he tried to stay calm and said (later he said he also had a cold sweat): I said how many times: Oracle server can no longer install Oracle client, if the customer's arrears data is lost, I Shang , you have to do a good job of the database again, Oracle's client installation process is modified by the contents of the registry, you need a control to change back. I was ordered to act at once.
Refer to the Oracle registry information on my machine, then modify it according to the customer's machine, and then lead the registry into the customer's registry. It is only by resignation that the service is valued. It works after the heavy lifting. Oh, my God.
This experience is really a lesson, this time is good luck and can recover. The big lesson is that, in the future, to the client, no matter what the job,
First of all, the database backup!!!!
Make sure you back up,!!!!!!!.
Here is the information I use the registry:
Windows Registry Editor Version 5.00
