IBM manual Requirements and limitations in Windows platforms, 24 DB2 Deployment Guide

￿Configuration Assistant and Control Center are not available on non-root installation.

￿Ability for the db2governor to increase priority is not supported.

￿Agent priority set by Work Load Manager (WLM) in a DB2 services class in a non-root DB2 instance will not respected.

￿Automatic starting of non-root DB2 instances at system reboot is not supported.

￿Sending alert notifications, running script or task action on alert occurrences in Health monitor are not supported in non-root installation.

￿Only single-partition databases are supported in non-root installation (no additional database partition can be added).

￿Non-root user can have only one copy of a DB2 product installed.

￿Non-root installation can have only one DB2 instance created during installation (for non-root user ID). No other instances can be created

￿Root installation and non-root installations can coexist on the same computer in different installation paths. However, DB2 instance action on non-root instance can be performed only by the instance owner of non-root instance.

￿DB2 instance commands such as db2icrt, db2iupdt, db2idrop, and db2imigr are not available in non-root installation.

￿Root installed instance cannot be migrated to a non-root instance.

￿Operating system-based authentication, High Availability (HA) feature, ability to reserve service name in the /etc/services file, ability to increase ulimit (in AIX) are not available in non-root installation. However, these limitations can be overcome by running the Enable root features for the non-root installation command (db2rfe).

Note: As operating system-based authentication is the default authentication type for DB2 products without running db2rfe, non-root user must manually set the authentication type in database manager configuration (dbm cfg) file.
