In IBM mainframe technology, a channel-to-channel adapter (CTCA)- Channel-to-channel adapter
9 related topics
High-performance input/output architecture that is implemented in various forms on a number of computer architectures, especially on mainframe computers.
Built-in channel-to-channel adapters were also offered, called CCAs in Amdahl-speak, but called CTCs or CTCAs in IBM-speak.
Feature of the VM/370 operating system introduced in Release 3 in 1976.
It provides a simpler interface and greater performance than the prior use of virtual channel-to-channel adapters for the same purpose.
Component of z/OS that manages communications between applications in a sysplex.
Dedicated channel-to-channel links (CTC links).
Procedure for sending requests for non-interactive data processing tasks to mainframe computers from remote workstations, and by extension the process of receiving the output from such jobs at a remote workstation.
The initial versions of NJE for JES2, JES3 and VM RSCS used BSC multileaving, but IBM quickly added support for Channel-to-channel adapters.
Member of the IBM System/360 family of computers.
The I/O options include one channel-to-channel adapter (CTCA) and up to three selector channels.
Discontinued line of mainframe computers, the first model of which, the IBM 3033 Processor, nicknamed "The Big One", was introduced March 25, 1977.
An optional channel-to-channel adapter (CTCA) is available.
Implementation of loosely coupled multiprocessing for IBM's OS/360 operating system.
ASP was introduced in March 1967, and initially allowed connection of two System/360 computers via a channel-to-channel adapter (CTCA).
Component within the IBM z/OS operating system responsible for enabling fair access to serially reusable computing resources, such as datasets and tape drives or virtual resources, such as lists, queues, and control blocks.
GRS Ring - each of the systems (LPARs) are connected with channel-to-channel adapters (CTCAs) in a ring configuration. The GRS software sends messages around the ring to ensure the integrity of the complex and to arbitrate correct succession of ownership.
Component of IBM's MVS mainframe operating systems that is responsible for managing batch workloads.
