IBM VERSION 9 manual Package requirements for SUSE Linux, Package requirements for Red Hat

By default, DB2 uses rsh when executing commands on remote DB2 nodes, for example, when starting a remote DB2 database partition. To use the DB2 default, the rsh-server package must be installed (see table below). For a comparison between rsh and ssh, see the “Security issues when installing DB2” section of the Administration Guide: Implementation.

If you choose to use the rsh remote shell utility, inetd (or xinetd) must be installed and running as well. If you choose to use the ssh remote shell utility, you need to set the DB2RSHCMD registry variable immediately after the DB2 installation is complete. If this registry variable is not set, rsh is used. For more information on the DB2RSHCMD registry variable, see the Performance Guide book.

vThe nfs-utils Network File System support package is required for partitioned database systems.

All required packages should be installed and configured before continuing with the DB2 setup. For general Linux information, see your Linux distribution documentation.
