 Application name must match folder name
What about Old Applications?
 Create a folder under /System/Applications
 Set isGridCapable keyword
 If name is different, set name on isGridCapable keyword
 isGridCapable:SAS Enterprise Miner Mid-Tier
 isGridCapable:*SAS Enterprise Miner
 isGridCapable:SAS Enterprise Miner*
 isGridCapable:*SAS Enterprise Miner*
Keywords
Helping the match-making process
 Make sure application sends APPNAME to spawner
 Make sure APPNAME matches
 Folder name
 isGridCapable pattern
 Make sure a mapping exists for app server and user
