NCPView

NCPView enables you to view the configuration of IBM 3745 and 3746-900 communications controllers that are running Network Control Programs (NCPs), and any problems with them. NCPView gives you greater network and NCP availability by allowing you to monitor NCP versions 4, 5, 6, and 7.

NCPView is of value to you as a network operator as it provides increased visibility of your NCPs, including supported non-SNA protocols and physical interfaces. By using the data provided by NCPView, you have the potential to both solve problems and prevent problems from occurring in your network (for example, slow response times and inability to access the system).

NCPView Features

NCPView provides the following features to assist you in monitoring your NCPs:

Lists and summary information of NCPs
Formatted dumps of NCP control blocks and storage displays
View of an NCP unformatted dump as a real NCP
Display of adapter and token-ring information
Display of frame relay physical links and subports
Display of buffer and pool information
Display of networks attached using SNI
Display of IP router statistics
Display of transmission group information
Display of NCP utilization
Display of virtual route information
History of monitored attributes (utilization, buffer use, and pool usage)

NCP Resources That Can Be Monitored

By using the data provided through NCPView’s interactive panels and diagnostic aids, you can solve problems and prevent them from occurring (for example, slow response times and inability to access the system).

The NCP resources that can be monitored by NCPView and the information provided for each are as follows:

NCP Configuration: Provides the NCP release, generation date and time, subarea address, and usage tier.
Communication Controller Configuration: Provides the controller model, storage size, operating mode, and maintenance and operator subsystem (MOSS) engineering change (EC) and FIX levels.
Processing and Storage: Provides the use of central control unit (CCU) cycles and NCP buffers, and the display of NCP storage in dump format.
NCP Control Blocks: Provides the size and use of NCP control block pools.
Virtual Routes: Provides window sizes, traffic rates, and congestion.
Transmission Groups: Provides the type, status, and queue sizes.
SNA Network Interconnection (SNI) Resources: Provides the network names table, Half-session Control Blocks (HSCBs), and Gateway Network Addressable Units (GWNAUs).
IBM 3745 Channel and Line Adapters: Provides the type, address, and status.
Token-ring Resources: Provides Token-ring Interface Couplers (TICs), physical and logical lines, stations, and routes.
Internet Protocol (IP) Resources: Provides IP router statistics.
3746-900 CSS (Connectivity SubSystem) Adapters: Provides adapters that are on the 3746-900 expansion frame.
