If you need centralized management and the number of managed systems does not exceed the recommended limits, as determined by the size of a domain manager, a single domain is recommended.
If you need centralized management and the number of managed systems exceeds the recommended limits, as determined by the size of a domain manager, an enterprise with multiple domains is recommended.
There may be other reasons for choosing an enterprise approach, even if a single domain is suitable for managing all managed systems. There may be requirements for administrators of individual sites to have full control over the managed systems within that site. In this case, a domain per site may be suitable. However, a degree of local autonomy may also be achieved using the security mechanisms in CA ITCM to split ownership of agents and other objects in the management database of a domain manager between multiple administrators.
In most scenarios, it is useful to install the enterprise manager when multiple domains are being used. Enterprise reporting is one benefit. Even if management of agents is performed strictly by the domain administrators, it may be valuable to produce enterprise-wide reporting on all agents and software in the enterprise. An additional advantage of the enterprise is the integration between CA ITCM and other CA Technologies software, such as CA Service Desk Manager and Unicenter Asset Portfolio Management. Many companies prefer to have a centralized help desk or procurement function even though administration of managed systems is distributed between site administrators using multiple domains. In such scenarios, we recommend that you use an enterprise solution to achieve maximal benefit from the inter-product integration. Note that if a single domain is deemed sufficient, inter-product integration is also available at domain level.
