  2. Virtual Storage Access Method - Wikipedia

    en.wikipedia.org/wiki/Virtual_storage_access_method

    Custom programs can access VSAM datasets through Data Definition (DD) statements in Job Control Language (JCL), via dynamic allocation or in online regions such as in Customer Information Control System (CICS). Both IMS/DB [citation needed] and Db2 [2]: 41 [6] are implemented on top of VSAM and use its underlying data structures.

    IDCAMS ("Access Method Services") generates and modifies Virtual Storage Access Method (VSAM) and Non-VSAM datasets. IDCAMS was introduced along with VSAM in OS/VS; the "Access Method" reference derives from the initial "VSAM replaces all other access methods" mindset of OS/VS. IDCAMS probably has the most functionality of all the utility ...

    en.wikipedia.org/wiki/Job_Control_Language

    Job Control Language (JCL) is a scripting language used on IBM mainframe operating systems to instruct the system on how to run a batch job or start a subsystem. [1] The purpose of JCL is to say which programs to run, using which files or devices [2] for input or output, and at times to also indicate under what conditions to skip a step.

    JCL is used to define jobs to both JES2 and JES3, but small changes usually need to be made to the JCL to get a job written for one JES to run on the other. A common issue was that JES3 checked that all datasets listed in the JCL existed before execution or that there was a prior step where the dataset was defined as NEW,CATLG.

    Multiple Virtual Storage, more commonly called MVS, is the most commonly used operating system on the System/370, System/390 and IBM Z IBM mainframe computers.IBM developed MVS, along with OS/VS1 and SVS, as a successor to OS/360.

    Instead, the notion of maintaining all data in leaf nodes is repeatedly brought up as an interesting variant of the B-tree, which was introduced by R. Bayer and E. McCreight. [2] Douglas Comer notes in an early survey of B-trees (which also covers B+ trees) that the B+ tree was used in IBM's VSAM data access software, and refers to an IBM ...
