A MultiSite license is required for any access to an object in a replica—by a MultiSite command or GUI, by a ClearCase command or GUI, or by a standard operating system command. You can calculate the number of MultiSite licenses you need by determining how many developers will access replicated VOBs. If all developers will access these VOBs, you need the same number of MultiSite licenses as ClearCase licenses. If some developers will not access replicated VOBs, you can purchase fewer MultiSite licenses.
For example, a company has two sites, with 20 developers at site A and 5 developers at site B. The company has three VOBs at site A; two will be replicated to site B and one will not be replicated. Five developers at site A will access only the unreplicated VOB, and the other 15 will work in all VOBs. Therefore, the company needs to purchase the following numbers of licenses:
Note: This example assumes that you purchase one ClearCase license for each developer. If you have fewer ClearCase licenses than developers, you can purchase a proportionate number of MultiSite licenses. For example, if the company purchased three ClearCase licenses for site B, it would also purchase three MultiSite licenses for site B.
