Chapter 4. Installing DB2 database servers using the DB2 Setup wizard (Windows)
This task describes how to start the DB2 Setup wizard on Windows. Use the DB2 Setup wizard to define your installation and install your DB2 database product on your system. Before you begin
Before you start the DB2 Setup wizard: v Ensure that your system meets installation, memory, and disk requirements. v If you are planning to use LDAP to register the DB2 server in Windows operating systems Active Directory, extend the directory schema before you install, otherwise you must manually register the node and catalog the databases. For more information, see the “Extending the Active Directory Schema for LDAP directory services (Windows)” topic. v You must have a local Administrator user account with the recommended user rights to perform the installation. In DB2 database servers where LocalSystem can be used as the DAS and DB2 instance user and you are not using the database partitioning feature, a non-administrator user with elevated privileges can perform the installation.
Note: If a non-Administrator user account is going to do the product installation, then the VS2010 runtime library must be installed before attempting to install a DB2 database product. The VS2010 runtime library is needed on the operating system before the DB2 database product can be installed. The VS2010 runtime library is available from the Microsoft runtime library download website. There are two choices: choose vcredist_x86.exe for 32-bit systems or vcredist_x64.exe for 64-bit systems. v Although not mandatory, it is recommended that you close all programs so that the installation program can update any files on the computer without requiring a reboot. v Installing DB2 products from a virtual drive or an unmapped network drive (such as \hostnamesharename in Windows Explorer) is not supported. Before attempting to install DB2 products, you must map the network drive to a Windows drive letter (for example, Z:).
Restrictions v You cannot have more than one instance of the DB2 Setup wizard running in any user account. v The DB2 copy name and the instance name cannot start with a numeric value.The DB2 copy name is limited to 64 English characters consisting of the characters A-Z, a-z and 0-9. v The DB2 copy name and the instance name must be unique among all DB2 copies. v The use of XML features is restricted to a database that has only one database partition. v No other DB2 database product can be installed in the same path if one of the following is already installed: – IBM Data Server Runtime Client
