Therefore, it might be necessary to consider remote database connectivity/ catalog during the DB2 server deployment planning if you have the following configurations:

￿The applications running on the same machine as the DB2 server has to access a remote database.

￿Database federation is enabled and other databases have to be accessed by the local server through a nickname.

￿High Availability Disaster Recovery (HADR) is set up.

DB2 provides useful utilities to copy the configuration from a test environment to a production system easily. In the following sections, we introduce DB2 configuration assistant, db2cfexp, db2cfimp, db2look, and db2rspgn.

DB2 Configuration Assistant

DB2 Configuration Assistant is a GUI tool that provides assistance with cataloging remote DB2 servers as well as certain administrative tasks. The DB2 Configuration Assistant can perform administrative tasks such as export or import configuration profiles, binding files, adding new databases, and configuring CLI settings.

Note: Beginning with DB2 9.1, GUI tools are only available for Windows x86, Windows x64 (AMD64 and Intel EM64T), 32-bit Linux x86, Linux for AMD64, and Intel EM64T. That means you cannot directly use GUI tools on other platforms such as AIX, HP-UX, and Solaris.

However, you can continue using the GUI tools on the supported platforms and remotely administer DB2 servers running on AIX, Solaris, or HP-UX where no GUI tools are installed. In general, these GUI tools do not differentiate remote DB2 servers from local ones.

Some administrative tasks require an administration server to be created. Make sure that you have DAS created and started on the same machines where the DB2 servers are to be administered by the GUI tools.

The command for starting DB2 Configuration Assistant is db2ca. On Windows, besides the command line, you can also open it from Start Programs IBM DB2 DB2COPY1(default) Set-up Tools Configuration Assistant. The configured connectivity entries, both local and remote, are presented as shown in Figure 2-1.
