Prerequisites for changing a Windows database server to a Linux Database Server

Prerequisites for changing a Windows database server to a Linux Database Server

The prerequisite is:

Please contact the application software developer and O & M personnel for confirmation:

First, whether the Window database server has an application software that obtains data (or extracts data. If yes, you need to check whether the application software that obtains data (or extracts data) has a corresponding version in linux.

2. Whether the hardware interface (USB, parallel port, etc.) of the Window database server is connected to a dongle. If so, you need to ask the app developer if there is any driver in linux. This dongle is generally used to prevent unauthorized use of the application software. Generally, application software has a technical authorization mechanism (dongle, serial number, and so on) to prevent you from using it illegally and use it out of date.

Oracle database software does not have a technical authorization mechanism. That is to say, there is no mechanism limit. "You can only use three months, and the fourth month will not be available ". Oracle database Software authorization is legally authorized. The IBM DB2 database software has a technical authorization mechanism. After expiration, the DB2 service cannot be started without entering the authorization file.
