MOTCLE ABBREVIATION DESCRIPTION
access method A technique for moving data between main storage and input/output devices
access method A technique for moving data between main storage and I/O devices
Access method An IBM-specific bit of jargon for software which moves data between main store and I/O devices. Access methods create channel programs and manage system buffers, and have implicit file structures. IBM access methods include TCAM, BTAM, VTAM, VSAM.
access method services AMS A multifunction utility named IDCAMS that is used to manage catalogs, devices, and both VSAM and non-VSAM data sets
access method services AMS langage de commande pour la gestion des fichiers VSAM (programme IDCAMS)
access method services AMS The utility that allocates and configures VSAM data sets. AMS is invoked through the AMSERV command in CMS
AM See Access Method.
AMS Access Method Services. z/OS and VSE subsystem for performing various data-related actions on VSAM and ICF catalogs, including defining VSAM datasets, and deleting and copying most dataset types. In short, a multi-purpose utility. Also known as IDCAMS because that is the program name you specify.

BSAM See basic sequential access method
BTAM See Basic Telecommunications Access Method
BTAM Basic Telecommunications Access Method. The first access method common to the predecessors of VSE/ESA and z/OS provides low-level services for reading from and writing to TP devices. Problems with the complexity of BTAM led to the evolution of TP monitors such as CICS. BTAM was largely superseded by access methods, such as VTAM, which implement the SNA procedures (BTAM does not support SNA devices). Withdrawn for VSE/ESA June 2000 and z/OS March 2000. Support ends March 2002 for both platforms.

queued sequential access method QSAM An extended version of the basic sequential access method (BSAM). When this method is used, a queue of data blocks is formed. Input data blocks await processing, and output data blocks await transfer to auxiliary storage or to an output device
queued sequential access method QSAM An extended version of BSAM. When this method is used, a queue is formed of input data blocks awaiting processing or processed output data blocks awaiting transfer to auxiliary storage or to an output device
Queued Sequential Access Method QSAM A replacement or an extended version of the basic sequential access method (BSAM). With this method a queue is formed of input data blocks that are awaiting processing or of output data blocks that have been processed and are awaiting transfer to auxiliary storage or to an output device. This typically provides better performance because the application is not waiting for the physical reads or writes to and from the Input or Output devices.

SAM See sequential access method
SAM-E Sequential Access Method?Extended. Souped-up version of the original SAM sequential access method. The main innovation is that it supports sequential data striping. Until 1983, SAM-E was a separate software product. After being incorporated into DFP (now DFSMSdfp), SAM-E lost its name and became simply SAM. See also SAM.

VSAM virtual storage access method
VSAM Virtual Storage Access Method (aka Very Slow And Mysterious). IBM mainframe proprietary software for direct (by key or by record number) or sequential processing of fixed and variable length records on DASD. According to IBM, VSAM gives device independence of data storage and eases migration of data to new devices. VSAM is a very powerful system if it had record locking it would almost be a database. However, according to the third-party vendors who make a living selling VSAM software, VSAM software (notably IDCAMS) is a pig to use, and users need all the help they can get. See also KSDS, RRDS, ESDS.
VSAM See Virtual Storage Access Method
VTAM Virtual Telecommunications Access Method
VTAM Virtual Telecommunication Access Method. The main SNA subsystem resident in the mainframe, which manages session establishment and data flow between terminals and application programs, or between application programs. VTAM also contains the SSCP logic, and supports the execution of concurrent multiple teleprocessing applications, giving each application a logically direct connection with terminals. ACF/VTAM and the defunct ACF/VTAME were extended versions of VTAM for multi-host networks. In March 1992, IBM announced APPN for VTAM (Version 4.1), effectively sealing the lid on the coffin of subarea SNA. Multiprotocol support ?la Networking Blueprint was announced in April 1993. Today, VTAM is a component of Communications Server (CS) for z/OS. VTAM for z/VM and VSE/ESA are still separate products.
