The RTR System Management Environment

• 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, refer to the chapter on ‘‘Partition Management’’ in

the HP Reliable Transaction Router System Manager’s Manual.

RTR Runtime Environment

When all RTR and application components are running, the RTR

runtime environment contains:
• Client application
• Server application
• RTR shareable image, LIBRTR
• RTR control process, RTRACP
• RTR daemon, RTRD
• RTR command line interface, RTR CLI
• RTR command server, RTR COMSERV
Figure 5–2 shows these components and their placement on

frontend, router, and backend nodes. The frontend, router, and

backend can be on the same or different nodes. If these are all

on the same node, there is only one RTRACP process.
