GOAL:
How can you tell which database is the coordinator when using two-phase commit?
FACT(s) (Environment):
All Supported Operating Systems
Progress/OpenEdge Product Family
FIX:
In two-phase commit, Progress assigns a coordinator for each transaction. If you use the -crd parameter, this will assign a higher priority to that database. This does not mean that it will always be the coordinator. It is only more likely to be the coordinator for a transaction.
The proper syntax is:
proutil db-name -C 2phase modify [ -crd | -tp nickname ]
db-name
Specifies the database you are using.
-crd
Switches whether or not the database can serve as a coordinator database. If you specify -crd against a database that is a candidate for coordinator database, it is no longer a candidate. If you specify -crd against a database that is not a candidate, it becomes a candidate.
-tp
Identifies a new nickname for the coordinator database.
