ServiceNow Recommendations for Modifying Max Length of name and domain_path fields in Domain table - Support and Troubleshooting

ServiceNow Recommendations for Modifying Max Length of name and domain_path fields in Domain table Description  ServiceNow Recommendations for Modifying Max Length of name and domain_path fields in Domain table | Domain Separation

Description This article explains why it is NOT recommended to modify the Max Length for domain.name or domain.domain_path fields on the Domain table from the out of box values

Procedure The system constantly calculates and maintains the domain_path values based on the domain.name values and domain hierarchy within the domain structure A domain path is a series of 3 character codes separated by a slash delimiter which uniquely identifies the domain. In out of box instances, domain.name has a max limit of 40 characters and domain Path has a 255 character max length The domain tree supports 216,000 child domains with 63 levels within each domain Domain Path max length of 255 characters is just enough to support the maximum number of domains records and levels permitted within the instance As a result, if the underlying MaxLength values for domain.name or domain.domain_path fields are modified to either increase or truncate (truncating is never recommended anyways), there is no telling if the domain_paths can be calculated accurately by the system. Conclusion: ServiceNow does NOT recommend making any changes to the Max Length of domain.name and domain.domain_path fields
