gateway process
gateway process. In heterogeneous transaction processing, an individual process that
executes a resource manager routine to export a transaction branch from TMF to a
foreign transaction management system, import a transaction branch from a foreign
transaction management system to TMF, and participate in the closing agreement
protocol between the two transaction management systems.
generation. A file or group of files in an online dump that are dumped at a certain time.
Each generation provides a starting point for the file recovery process. Earlier
generations of online dumps provide earlier starting points. Each generation of a file on
tape has a different serial number; each file in an online dump generation has the
same serial number.
group commit. A mechanism for writing audit records for many transactions with one
physical access.
H
heterogeneous transaction. A transaction that is processed by different types of
transaction managers operating on multiple platforms. In heterogeneous transaction
processing TMF can start a transaction and then subcontract parts of it to one or more
foreign transaction management systems operating on platforms other than the
NonStop system. Alternatively, a foreign transaction management system can begin a
transaction and then subcontract parts of it to TMF.
home node. The system (node) where a BEGINTRANSACTION statement for a distributed
transaction is executed. Contrast with remote node.
homogeneous transaction. A distributed transaction that is processed by the same type of
transaction manager operating on the same platform.
hung transaction. A transaction that cannot be successfully aborted. The backout process
has attempted, but failed, to abort it.
I
incomplete transaction. A transaction that was active when the system failed; ultimately,
TMF backs the transaction out of the database.
independent product (IP). A licensed software product, independent of the standard
operating system release version update (RVU) and delivery process, that is generally
delivered on separate media from the NonStop Kernel operating system release
software. Independent products ship when ready with no dependency on the standard
operating system release and delivery process. An IP can be independently applied to
the current product release (CPR) or new feature production release (NFPR)
environments by the customer, depending on the availability of the IP’s requisites.
in-doubt transaction. See unresolved transaction.
