Notes on REORG Command
Label Records, Message Routing, and Tapes
• DYNUTIL dynamically constructs label records (DLBL/EXTENT) for each
extent selected from the input tape (except when Method 6 is used), and
invokes CA Dynam/D by performing an open.
• The CATALOG option causes the label records to be constructed without
EXTENT information, thereby placing the files being processed under
Catalog control. The target files must first be defined in the Catalog; if
they are not, no REORG occurs.
• If REORG is run from SYSIPT, many of the messages it issues appear only
on SYSLST. When it is run from the console, all messages appear on both
SYSLST and SYSLOG. All CA Dynam/D messages resulting from REORG
activity are issued in accordance with the options specified in the
DYNAM/D option record.
• You can use the DYNUTIL LISTTAPE command to produce a formatted
listing of the tape’s contents to verify the order of the files on the tape.
REORG Processing
• When using any of the options CATALOG, NEWDSN=, FILELBL or
CONVERT, only complete files are processed. Incomplete files are
bypassed with a diagnostic message.
• When files dumped from an FBA device are restored to a non-FBA device
using the REORG command, they must have the CISIZE in the original
Format-1 label. The files without the CISIZE are bypassed with a
diagnostic message.
• When an existing catalog-controlled file is restored using the REORG
command, the Catalog entry giving its location is updated to reflect the
new situation. This can only be relied upon, however, if the REORG
completes successfully and without error messages.
• Whenever a catalog-controlled file (or an extent of one) is restored using
the REORG command, the original file or extent is automatically deleted
from the volume where it resided. Where the file is being renamed by use
of NEWDSN= or NONAMECH, the original file is not deleted but the target
file is, if it is catalog-controlled. Noncatalog-controlled files (or extents) are
deleted only if they are restored to the original volume using the REORG
command.
• DYNUTIL searches the input tape in the forward direction only. If you issue
multiple REORG commands in one job, be sure the files you request in the
REORG command selection criteria are in the same order as they appear
on the tape. Otherwise, you must close and reopen the tape between
REORG commands.
