You've
got a problem. The number of
datasets you have is growing steadily, but your naming conventions are
outmoded and have to be adapted to today's needs. Or you want to integrate
another data center into your system and its naming conventions don't
match yours.
But changing a dataset name is a lot
of work: The dataset has to be renamed in the catalog, the DD statements
in the JCL have to be modified, symbolic parms have to be resolved, IMS
dynallocs and utilities have to be adapted – and on and on.
DSN/Change searches JCL libraries, data cards,
CLIST and REXX programs, CA-1 tape management definitions, RACF
profiles, IMS dynallocs and more for all references to the files you
want to rename. These references are then written to the internal
database of DSN/Change. A typical example of a reference is the DSN
parameter of a DD statement: DSN=FILENAME.
DSN/Change creates new file names according to
pre-defined rules. These rules are set and maintained by the user in
an ISPF dialog. Extensive utilities such as variables, tables and
string functions are available.
DSN/Change simulates all changes. In the so-called
TRY mode, old and new file names are listed next to each other and the
result you will get after conversion is displayed.
DSN/Change can reformat DD statements: BLKSIZE,
UNIT, VOLUME, MGMTCLAS, DATACLAS, STORCLAS and so forth can be
changed, added or removed automatically according to pre-defined
rules.
DSN/Change considers symbolic parameters in the JCL
and in procedures.
DSN/Change compares access
rights to old and new dataset names with each other. If they don't
match, the differences are displayed.
DSN/Change
renames the physical files (non-VSAM, VSAM, GDGs, IMS databases,
tapes) as well as all references to these files while production is
running.
DSN/Change
recalls migrated datasets. After renaming, these datasets are returned
to the media they were recalled from.
DSN /Change tracks all modifications: Complete and error-free, no revision is necessary. Such seamless tracking makes it possible to undo all changes at any time.
