Sequential Data set attributes

The server must KNOW the correct values for the following attributes. Please remember that values derived from SITE commands blindly override and replace values dervied from the view.

The following attributes (1 through 7) are always required (i.e., needed for both GET & PUT operations).

1) Real Data Set Name:                               to see how to pass the real data set name to the server..

2) TYPE:     Constant character string VSAM

3) DISP:      GET automatically forces Shr.
                   PUT, on the other hand requires you to specify either Mod or New:
                      a) Mod: extends (i.e., Appends) the file if it exists or creates a NEW one as per next item b.
                      b) New: Creates a new file. Disposition of New, or Mod for non-existing file, requires
                                    attributes 8 through 11 as well.

4) RECFM: F, FB, V, or VB to indicate Fixed, Fixed blocked, Variable, or Variable blocked, respectively.

5) RECL:     logical record length.

6) BLKSZ:   block size, if logical records are blocked.

7) Catalog DLBL: dlbl for the VSAM catalog pointing to the data set. Default is IJSYSUC.

    In addition, The following attributes (8 through 11) are required for new output files (i.e., client
    issues a PUT and specifies: DISP = NEW, or DISP = MOD for a non-existing file).
   GET, on the other hand, totally ignores these attributes.

8)   VOLSER: The application generates a DLBL with a VOLSER, if provided. Default is blanks.

9)   EXP: Expiration date YYYY/ddd, where ddd is julian day, or number of days. Default is 7 days.

10) Primary Space Quantity: Primary space quantity. The server provides a default, but do not depend on it.

11) Secondary Space Quantity: Secondary space quantity. Default is none.
