For Client setup, it will interact for the hostname or ip address
of the DB2 Server as known by the Service Node, unless the
XCATDB2SERVER environement variable is set.
See man db2setup for more information and the xCAT2SetupDB2.pdf
documentation.
See man db2setup for more information
The script will assume the default install paths of /opt/IBM/db2 for AIX and
/opt/ibm/db2 for Linux, unless overridden with the XCATDB2INSPATH
environment variable.
The script will assume /var/lib/db2 for the xcat db2 database directory
unless the
DATABASELOC environment variable is set or the site.databaseloc attribute is
set. The environment variable should match the
databaseloc attribute in the site table, but the DATABASELOC environment
variable will take precedence. DATABASELOC points to the directory that
contains the db2 database directory, so if DATABASELOC=/db2database then
the actual location for the db2 database is /db2database/db2.
-r flag will help you to remove DB2 from xCAT and uninstall DB2 from either
management node or service node. The flag -r and -S used together for
