Tape File Management Utilities
The following diagram illustrates the synchronization process:
Before catalog synchronization is performed, it is highly recommended that the
Catalogs on both systems be backed up using the product specific utilities
provided by each system.
Avoid updating the Catalogs between EXTRACT and APPLY functions. The
APPLY uses the status information in effect at the time when the EXTRACT was
performed; any intermediate updates followed by an APPLY can cause serious
errors.
TDYNSYNC Control Statements
Each TDYNSYNC control statement starts with one of the commands shown
below in logical processing order:
CATNAME=
EXTRACT
SYNC
APPLY
Optional. Can be specified with other TDYNSYNC commands. It defines the
source catalog for the EXTRACT, and the target catalog for the APPLY and
REMOVE commands.
Produces a file (dtfname=CAT1OUT) and a report that represent all entries in
the Catalog.
Takes as input the files produced by the EXTRACTs of the two catalogs
(dtfnames of CAT1IN and CAT2IN), synchronizes the information, then
produces two output files, one for each Catalog (dtfnames CAT1OUT and
CAT2OUT). A report of catalog entries is also produced.
Takes as input one of the output files (dtfname=CAT1IN) from the SYNC
command and updates the catalog.
