CA Dynam for VSE User Guide

DYNCAT Commands
NEXTGEN=
Optional parameter. Modifies the next disk generation ID number that is to be
used for CA Dynam/D-controlled disk generation datasets. Valid entry is:
a 1- to 2-digit number in the range 1-99.
CA Dynam/D creates a disk GDG by appending G#nn as the last 4 characters
of the 44-byte file ID. Normally, each successive generation receives the next
sequential number, from 1 through 99.
If it is necessary to reset this number to a lower value, the VTOC entries for
the already existing files above this number should be removed from the
DASD devices upon which they reside (with DYNUTIL DELETE). In addition,
remove their associated version records from the Catalog (with DYNCAT
DELETE) before the generation ID is updated with NEXTGEN.
NGEN=
Optional parameter. Changes the number of generations to be saved for this
dataset. Valid entries are a 1- to 3-digit number in range 0-999, for TAPE
datasets or DISK datasets.
See the DEFINE command for further discussion of the implications of NGEN
for TAPE and DISK datasets.
NOACC=
Optional parameter. Specifies the number of days this dataset version is to be
retained after last access, before it becomes eligible for scratch.
1- to 4-digit number in the range 0-9999.
OIMSG=
OOMSG=
OPEN=
See CIMSG operand description.
See CIMSG operand description.
Optional parameter that changes the DTF rewind option set by CA Dynam/T or
CA Dynam/FI for OPEN.
NORWD
RWD
NO
not to rewind the tape.
forces the rewind.
removes the OPEN options.
OVRfl=
OVRfl=(volser,unit,q1,q2,SYSnnn)
Optional parameter which defines the allocation characteristics of the
independent overflow to be generated for the (ISAM) disk dataset if it is to be
allocated by the CA Dynam/D component. Valid entries are the same as for the
PRIME data allocation (except for the sequence option).
