DB2 is IBM's relational database management system introduced. Mainly used in banks, hospitals and other large institutions. DB2 now mainly consists of the following three series: DB2 for Linux, UNIX and Windows (LUW).
DB2 Installation depends compat-libstdc ++ libraries under Linux, the library needs to be installed first before installing DB2. Attaching the library run db2setup start the graphical interface DB2 installation program after the completion of the installation:
DB2 creates during installation db2inst1, db2fenc1 and dasusr1 three users, this three users will be added to the system to become users of the system can also be created prior to installation:
After switching to the db2inst1 user installation, operation db2cc start the graphical control center (DB2 V10.1 release from the start no longer contains graphical control center, using a command line or provided in IBM Data Studio management tools);
DB2 installation under Windows:
Run the installation program setup.exe program to start the installation, the installation process creates db2admin user and add this user to the Administrators group
After installation is complete db2cc launch control center:
DB2 service names and the port can be viewed using the following method:
Linux：
/ Etc / services file
Windows：
C: \ Windows \ System32 \ drivers \ etc \ services file
DB2 default port 50000 listens for connections
DB2 users
All users are operating system DB2 user, and the user password is also bundled with the operating system the user's password.
Under Linux, installing DB2 creates db2inst1, db2fenc1 and dasusr1 three users. Under Windows, the user db2admin created and added to the Administrators group.
Local operating system user is not all DB2 users, we need to add operating system user database in DB2 user management function.
In the Windows operating system, which is the command CLP-enabled command line window; in this case, you must start the DB2 command line environment (from the general command window) run db2cmd command.
Windows command line:
Under Linux users need to create db2: Enter su -db2admin to switch.
