There are some limitations of the non-root installation of which you should be
aware. For DB2 server products, some limitations of a non-root installation are as
follows:
DB2 Administration Server and related commands are not available:
dascrt
,
dasdrop
,
daslist
,
dasmigr
, and
dasupdt
.
DB2 Control Center and DB2 Configuration Assistant are not available.
The agent priority set with Work Load Manager (WLM) in a DB2 service class
in a non-root DB2 instance is ignored and no SQLCODE is returned.
Automatic startup of the non-root DB2 instance is provided, because the
system reboot is not supported.
Partitioned database is not supported.
For a complete list of limitations, refer to the following URL:

By default, non-root installation does not support operating system-based
authentication. You have to manually set authentication parameter in the
Database Manager Configuration after the installation. However, by running the
command
db2rfe
, you can enable the supported root features according to the
configuration file after the non-root installation. In addition to the operating
system-based authentication, there are other limitations that can also be restored
by running
db2rfe
:
High Availability (HA) feature
Adding new service entries in /etc/services
Increasing user data limits (
ulimit
); this ability applies to AIX only
Elevated privileges installation on Windows
Just like the non-root installation for UNIX/Linux platforms, DB2 9.5 for Windows
has a counterpart feature called elevated privileges installation, also known as
non-Administrator installation.
To perform the elevated privileges installation, prior to the installation you have to
identify a non-Administrator account used to perform the installation task. A
member of the Administrators group is required to configure the Windows
elevated privileges settings to allow the non-Administrator to perform an
installation.
