B.9 Server States - Compaq AA-Q88CE-TE System Manager's Manual

Server Shadowing and Recovery
B.8 Application Considerations
• Any physical reference to the transaction which is unique to the executing
server, e.g. Channel Id, system time, DB-key, etc., should not be passed back
to the client for future references within its subsequent messages, as this
could lead to inconsistent handling when a different server is involved in
shadow operations.
This consideration is also valid for recovery of non-shadowed servers.
