NOW-DSC-DOMAIN_TABLE_BEST_PRACTICE_TOO_MANY_DOMAINS
Severity	Warning
Root Cause	There is a specific threshold below which a domain-separated environment can run with optimum performance. As domains are added past that threshold, memory usage on the instance becomes burdened, affecting performance. Lack of planning when the domain hierarchy was defined or lack of effective policy to retire domains that are no longer in use can lead to a large set of domains. This large set of domains may not be contributing to the proper use of domains in the instance and may be impeding performance of the instance as a whole, not just in the administration and use of domains.
Effect	A large number of domains that exceeds the recommended threshold will unnecessarily increase memory usage and affect performance.
Corrective Action	Remove any unnecessary domains from the domains table.
