Resource Group Name Standards

The concept of Resource Group is used here in a larger scope than it is used in HACMP. In CGE's environment, a resource group is any logical collection of resources, this may include disk, I/O, users, applications, etc. A resource group should be viewed as being independent from any machine or data center. The resource group name is used as the basis of all other naming structures for all entities whether or not they are controlled by HACMP. The resource group name shall be an enterprise wide unique value in order to eliminate conflicts during manual, automated, or disaster recovery failovers.

When designing any new system, the first step is to determine the resource group name(s). The names of volume groups, logical volumes, mount points, major numbers, WLM classes, etc, are all derived from the resource group name(s).

The resource group name shall consist of exactly 8 characters with the following structure:

ApplicationCode + Environment + Function + Company + Sequence ID
     3 char     +    1 char   +  1 char  +  2 char +   1 char

The detailed information for each component of the resource group name is described below:

RG Name Component	Number of Characters	Values
Application Code	3	atl = Atlas ega = EGATE nim = NIM ora = Oracle tps = Maximo vio = Virtual I/O
Environment	1	a = acceptance a = pre-production d = test/development p = production t = test x = disaster recovery x = pre-production
Function	1	a = application c = combination/multi-purpose d = database m = management u = utility
Company	2	cg = Capgemini ce = Capgemini Energy tu = TXU tw = Time Warner
Sequence ID	1	0-9,A-Z,a-z
