Compaq Reliable Transaction Router manual RTR Runtime Environment

	The RTR System Management Environment
Partition	Partitions are subdivisions of a routing key range of values used
Management	with a partitioned data model and RTR data-content routing.
	Partitions exist for each range of values in the routing key for
	which a server is available to process transactions. Redundant
	instances of partitions can be started in a distributed network,
	to which RTR automatically manages the state and flow of
	transactions. Partitions and their characterisitcs can be defined
	by the system manager or operator, as well as within application
	programs.
	RTR management functions enable the operation to manage
	many partition-based attributes and functions including:
	• Creation/deletion of a partition with a user-specified name
	• Defining/changing a key-range definition
	• Selecting a preferred primary node
	• Selecting failover precedence between local and cross-site
	shadows
	• Suspending/resuming operations to synchronize database
	backup with transaction flow
	• Overriding the automatic recovery procedures of RTR with
	manual recovery procedures, for added flexibility
	• Specifying retry limits for problem transactions
	The operator can selectively inspect transactions, modify states,
	or remove transactions from the journal or the running RTR
	system. This allows for greater operational control and enhanced
	management of a system where RTR is running.
	For more details on managing partitions and their use in
	applications, see the RTR System Manager's Manual chapter
	``Partition Management.''
