B.2 DDSR Command

In this section we present examples of the IXFP DDSR command.

Remember: Before you can use the DDSR option against a volume, you must bring it offline by using the DVCDN VSE/ESA command.

Figure 28. Syntax of IXFP DDSR Command: Details

DDSR If specified without any additional operand, the operator can delete the VTOC entries and all physical space for all non secured files residing on VSE-managed RVA devices whose associated expiration date has been reached and which have been created by VSE. A request is sent to the RVA subsystem, causing the RVA subsystem to release the physical extents that VSE considers as free space. Once released, these extents are reclaimed for free space allocation.

If a unit parameter is used, without any additional operands, the data on the entire volume will be deleted (including the VTOC and the VOL1 label). Therefore the volume must be reinitialized (ICKDSF) before it is used as a regular data-pack again, assuming it is not going to be used as a SNAP target device, in which case such an initialization run would be obsolete. VSE requires the volume to be DOWN (DVCDN command) if the whole volume or a range of cylinders is to be deleted.

unit The device ID (cuu) or the VOL1 label of the device that should be either totally released or, if a data set name (DSN=) or a cylinder range has been specified, partially released. The VTOC on this device will remain unchanged unless a file was released, in which case the appropriate labels will be deleted from the VTOC. If you release the whole volume, or the cylinder range containing the VTOC, the VTOC will be deleted. dcyl-dcylSpecifies the decimal start cylinder and end cylinder

where deletion is to start and to end. Cylinder is the smallest entity that can be specified for any DDSR command function. The highest (end) cylinder number must not exceed 32767, and the start cylinder number must not be higher than the end cylinder number.

dcyl.ncyl Specifies the decimal start cylinder where deletion is to start and provides the number of cylinders (ncyl) that should be released. Cylinder is the smallest entity that can be specified for any DDSR command function. The highest resulting cylinder number must not exceed 32767 or the device′s number of primary cylinders.

D S N = The data set name identifying the file on the specified unit that the operator wants to be deleted. The file must be a non-VSAM file, If the specified unit is in the
