ART CICS runtime will find VSAM configuration file through the environment variable $DD_VSAMFILE, which could be exported or defined in the envfile and used to indicate the location of VSAM configuration file.Table 5‑1 lists and defines VSAM file configuration parameters available to be referenced by the CICS application.The filename is desc.vsam.
Table 5‑1 VSAM Configuration Parameters Mandatory, if TYPE is Fixed Mandatory, if ORGANIZATION is Indexed Mandatory, if ORGANIZATION is Indexed ENABLED: Normal processing is allowed against this file.DISABLED. Any request against this file from a command-level application program causes the DISABLED condition to be passed to the program.UNENABLED: This prevents the file being opened by an implicit open from an application program. Any such attempt to access the file raises the NOTOPEN condition. By contrast, an explicit request to open the file (for example, EXEC CICS SET FILE OPEN command) changes the status to ENABLED before attempting to open the file. STARTUP: The file is opened immediately after CICS initialization, unless the status of the file is UNENABLED when the file is left closed.FIRSTREF: The file remains closed until a request is made to open it by using one of the following methods:
• An EXEC CICS SET FILE OPEN command in an application program
