EMS Event Management Subsystem (Event Journal) / NSK Nonstop Kernel (Tandem operating System). Bingtang Used to create the visual appearance in the SI Nonstop GUI interface.Cope = Has to do with Payments / Star = Has to do with messages / SIHA = SI Host Adapter (from Star -> SNL Server->Swift.Tacl = is the command language used to interface with HP Nonstop When in tacl, you can use the enter key.Peruse $(x=sys)sls=spool of all jobs on the system / MAR = Message Application ReferenceISN = Each message input from a bank to the system is given an input sequence number (ISN) and each output message from the system to a bank is given an output sequence number (ISN).Introduction to Banking - Page 287 (use link below)

A Memory Leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations[1] in such a way that memory which is no longer needed is not released. In object-oriented programming, a memory leak may happen when an object is stored in memory but cannot be accessed by the running code.[2] A memory leak has symptoms similar to a number of other problems (see below) and generally can only be diagnosed by a programmer with access to the program's source code.Because they can exhaust available system memory as an application runs, memory leaks are often the cause of or a contributing factor to software aging.

A COBOL Run Unit - is a set of one or more programs that function as a unit at run time to provide a problem solution. A COBOL run unit is an independent entity that can be executed without communicating with, or being coordinated with, any other run unit except that it can process data files and messages or set and test switches that are used by other run units. A run unit can also contain program objects and service programs created from module objects that are created from the compilation of programs written in languages other than ILE COBOL. In ILE, a COBOL run unit is composed of program objects and service programs that all run in a single ILE activation group.

Regional Processor (RP- Swift) - The node of the FIN system that communicates with a user's (LT) logical terminals. The Regional Processor is primarily responsible for input message validation and output message queues for multiple destinations in a particular country. Within the flow for a single message, the Input Regional Processor and the Output Regional Processor may be the same node, depending on the location of the sender and the receiver. For an individual user, the Input Regional Processor is always the same node as the Output Regional Processor.

(RDF) - Remote Database Facility - RDF monitors changes made to a production database on a local (primary) system andmaintains a copy of that database on one or more remote (backup) systems. Because it applies changes to the backup database as soon as they are detected on the primary system, RDF keeps the backup database continuously up to date with changes made by business applications on the primary system. You are able, therefore, to switch your business operations from the primary system to the backup system with minimal interruption and loss of data in the event of planned or unplanned outages of the primary system. With NonStop RDF/ZLT, the failover involves no loss of data. RDF also allows you to use backup databases as read-only resources to balance the overall workload and improve response times. Activities at a backup system can include querying the database, processing heavy batch-reporting loads, and consolidating data from multiple sites into one central site. Backup systems may be located far from the primary system for protection againstregional disasters, communicating with the primary system over an Expand network. System managers and operators control RDF through RDFCOM, a utility much like the TMFCOM command interpreter used to access TMF. RDF/IMP, IMPX, and ZLT generate fully-tokenized command, event, error, and warning messages in the Event Management System (EMS) log. System managers and operators can monitor those messages online using Viewpoint or whatever other tool they normally use for monitoring $0. In addition, they can use the supplied EMS filter RDFFLTO with an EMS printing distributor to isolate the RDF messages to an entry sequenced file which they then can peruse using the RDFSCAN utility.RDF works with the Transaction Management Facility (TMF) subsystem.

(TMF) - Transaction Management Facility - Handles the various aspects of fault tolerance on the system level, transparent to the application. TMF furnishes transaction protection, database consistency, and database recovery critical in high-volume transaction processing. It sustains high performance for online transaction processing (OLTP) applications, as well as online query processing (OLQP) activities, batch processing applications, and decision-support systems.
