forSC19-6203-1 as Updated by SN24-5736
Missing Interrupt Handler
The missing interrupt detector has been extended so that CP not only detects
missing interrupt conditions, but also attempts to correct them. CP informs the
system operator whether or not the corrective action was successful.
To help give you optimum system availability, the missing interrupt handler
allows you to vary the time interval allowed forI/O completion for the sup
ported devices.
3880 Speed Matching Buffer (Feature #6560)
The3880 Speed Matching Buffer Feature for the IBM 3375 uses a 16K-byte
storage buffer to modify the direct access data transfer path between the 3375
and the mUltiplexer channel. The feature allows attachment of the 3375 Direct
Access Storage Device, with its 1.859 megabytes per second data rate, to block
multiplexer channels with data rates as low as 1.5 megabytes per second, as
well as to high speed multiplexer channels.
Miscellaneous
The Programmable Operator Facility section of this publication has been
rewritten to include minor technical and editorial changes.
Summary of Changes
forSCI 9-6203-1 for VM/SP Release 2
Programmable Operator Facility
This facility provides the capability to: log messages, suppress messages, redi
rect messages, execute messages, or preprogram message responses. The
capabilities are under control of an editable message routine table in a CMS
file.
Inter-User Communication Vehicle (IUCV) enhancements for message handl
ing are also included.
CMS Nucleus Restructure, and Removal of the CMS Tokenization Eight-Byte
Restriction
The restructured nucleus provides a CMS system that is more flexible and
extendable for development, serviceability, and maintenance purposes.
The eight-byte tokenizer restriction has been removed for parameter passing.
