3.10. Summary
In this chapter we discussed four DB2 installation methods:
- Using the DB2 Setup Wizard
- Using a response file
- Using the db2_install script
- Using native operating system install tools
The first two methods are available on all supported platforms; the last two are only available on Linux/UNIX platforms. The recommended method to install DB2 is by using the DB2 Setup Wizard. If you use the DB2 Setup Wizard or the response file methods, you have the choice to create a DB2 instance and the DAS during installation. The instance owner user ID and the DAS user ID are also created. If you use the other two methods, you must manually create the user IDs and the instance after the installation is completed. If you use the native operating system install tool to perform the install, you must install the DB2 license manually.To install DB2 in a DPF environment with multiple machines, the recommended installation method is the Silent install. Copy the DB2 install image from the CD-ROM to a shared disk, then run the DB2 setup program from each machine to install DB2 locally.There are two different types of DB2 FixPaks: the regular DB2 FixPaks and the alternate DB2 FixPaks. Both types of FixPaks contain fixes to APARs. However, the alternate FixPak lets you maintain different FixPak levels of DB2 for the same version.
