17.2 Grid Configuration
17.2.1 Peer Configuration Overview
In the simplest case, establishing a peer-to-peer relationship can be accomplished with as few as two configuration lines: one line to indicate how to contact the peer and one line to indicate how to authenticate the server. However, data migration issues, credential mapping, and usage policies must often be addressed in order to make a peer-based grid effective.
To address these issues Moab provides facilities to control how peers inter-operate, enabling full autonomy over both client and server ends of the peer relationship.
17.2.2 Peer-to-Peer Initial Configuration
At a minimum, only two parameters must be specified to establish a peer relationship: RMCFG and CLIENTCFG. RMCFG allows a site to specify interface information directing Moab on how to contact and inter-operate with the peer. For peer interfaces, a few guidelines must be followed with the RMCFG parameter:
- the TYPE attribute must be set to moab
- the SERVER attribute must point to the host and user interface port of the remote Moab server
- the name of the resource manager should match the name of the remote peer cluster as specified with the SCHEDCFG parameter
Example
When specifying the CLIENTCFG parameter for peers, the following guidelines must be followed:
- the CLIENTCFG parameter must be specified in the moab-private.cfg file
- an RM: prefix is required before the peer's name
- if using default secret key based security, the value of the KEY attribute must match the KEY value set on the corresponding remote peer.
- the AUTH attribute must be set to admin1
