I guess you mean Alfresco Process Services? If so have you looked at Multi-schema multi-tenancy (MS-MT) | Alfresco Documentation and the links at the bottom of that page?

GRANT ALL ON primary_db.* TO 'alfresco'@'localhost';
If you want to create two tenants, you need to create two secondary databases:
