IOA Access Method files that are allocated during IOA, Control‑D, Control‑V, Control‑M/Analyzer, and Control-M/Tape installation are listed in Files Supported by the IOA Access Method, and use the following naming convention:
prefix.dbname.Ennn
where
prefix is the IOA Access Method file name prefix. The prefix is specified during product installation by setting relevant installation variables (for example, DBPREFB for Control‑M/Analyzer, and DBPREFD for Control‑D and Control‑V). The prefix can contain more than one qualifier.
dbname is the IOA Access Method file identifier name. The identifier name is specified during product installation as part of the name assigned by parameter DSN in the IOA Access Method file’s definition statements. For example, identifier name ACT is assigned to the Control‑D Active User Report list data component while ACTI is assigned to the Control‑D Active User Report list index component. The identifier name of an IOA Access Method file is never modified.
Ennn is the extent sequence number suffix generated internally by IOA Access Method management routines whenever an IOA Access Method file component is allocated. The suffix consists of the letter E followed by nnn, a number from 000 to 255, indicating an IOA Access Method file’s extent sequence number. A maximum of 255 additional file extents can be associated with each IOA Access Method file.
