Today, the customer visited (Japanese) and asked me the difference between DB2 and Oracle. Because it's not a DBA, I haven't really summed it up. But my first feeling: One is instance, one is database. Building Ora libraries and DB2 libraries is not the same. It's really はずかしい. System Architecture Overview First, we need to understand the architecture used by Oracle and understand how it differs from

The following articles mainly describe the commands of the DB2 database in the linux operating system, if you are interested in the commands of the DB2 database in the linux operating system, you can click the following article to view the instructions.

This time, our DB2 is deployed on Windows. Windows has a client that is called a graphical interface. But it does not seem to work well, we have some problems, let's solve it. First, add a database instance: Instances of DB2 are independent of each other, and instances can be considered as containers for databases. When the default DB2 is installed, it builds an

Brief introduction UNIX and Linux users typically check the processes running on their servers to perform problem analysis and to check the resources consumed in the server. This information is useful not only for administrators who perform issues and resource analysis, but also for those who develop high availability and failover scripts that monitor the DB2 process to determine when operations such as database restarts or server failover are require
