Governors setting is used to reduce system resource
requirements and improve performance. You set
governors before you create packages to ensure the metadata
in the package contains the specified
limits. All packages that are subsequently published will
use the new settings.
There are a number of governors that you can set. Governor
settings in the model can be
overridden by governor settings in Report Studio.
1.Report Table Limits
You can control the number of tables that a user can
retrieve in a query or report
2.Data Retrieval Limits
You can control the number of rows that are returned in a
query or report
3.Query Execution Time Limits
You can limit the time that a query can take
4.Large Text Items Limit
You can control the character length of BLOBS (binary large
objects) that a user can retrieve in a
query or report
5.Allow Enhanced Model Portability at Run Time
You can use a separate but structurally similar data source
at run time. The database schema must
be the same between the two data sources.
6.Allow Usage of Local Cache
Select this governor to specify that all reports based on
this model should use cached data.
7.Outer Joins
You can control whether outer joins can be used in your
query or report.
8.Cross-Product Joins
You can control whether cross-product joins can be used in
your query or report.
9.Use With Clause When Generating SQL
You can choose to use the With clause with Cognos SQL if
your data source supports the With
clause.
10.Suppress Null Values for Dimensional Data Sources
This governor is supported for SAP BW data sources only. It
does not work with relational or
OLAP data sources.
Some queries can be very large because null values are not
filtered out. Because null suppression is
performed by the underlying data provider, in this case SAP
BW, this reduces the amount of data
transferred to the various Cognos 8 client products, thus
improving performance and returning
only relevant data in the report.

Governor setting is basically used in Frame work Manager to
improve the performance of the reports in the way like
retrieving the number of tables or number of rows to be
displayed.These setting are done before creating the
packages to ensure the data or the information that is to
be retrieved is restricted.As well you have different types
of governor setting depending upon the data you want to
retrieve.
