The DB2_LIMIT_FENCED_GROUP registry variable allows restricting the operating system privileges of the fenced mode process (db2fmp) to the privileges assigned to the DB2USERS group. This variable only has effect if extended security is enabled (DB2_EXTSEC) and the Db2 Service Account is not LocalSystem. This registry variable only applies to Db2 Servers running on Windows.


By default, the fenced mode process has access to both the DB2ADMNS and DB2USERS groups.

This control is used in the following benchmarks:


To deliberately skip this control (e.g. meaning don’t use Puppet to enforce this setting), we provide you with three ways:

1) Add db2_secured::controls::limit_os_privileges_of_fenced_mode_process: skip to your hiera data. This will skip this control for ALL databases.
2) Add db2_secured::controls::limit_os_privileges_of_fenced_mode_process::instance_name::dbname: skip to your hiera data. This will skip this control for specified database only.
3) Add an entry with the content limit_os_privileges_of_fenced_mode_process to the array value db2_secured::skip_list in your hiera data.


Attribute Name Short Description
title The database identifier to apply the control to.


The database identifier to apply the control to.

All controls need an database identifier to apply the control to. Here is a simple example:

db2_secured::controls::control_name { 'db2inst1/MYDB':}

In this example, the string dbinst1 is the instance, the string MYDB is the database to apply the control to.
