ALTER SYNCFILESET
The security of the newly created destination catalog is set to the syncuser's
default Guardian security.
If the catalog already exists, the option is ignored.
To register the object in a different catalog, use the CATALOG option in
addition to AUTOCREATECATALOG.
BACKUP backup-program | NO BACKUP
the name of the BACKUP object program to use on the source system when a
file set is synchronized.
This option overrides the BACKUP option specified in the ADD SYNCUSER or
ALTER SYNCUSER command.
If BACKUP is omitted, $SYSTEM.SYSnn.BACKUP is used.
CATALOG SQL-catalog | NO CATALOG
where to register SQL objects that are synchronized. If CATALOG is omitted,
the source catalog name is used.
If the needed catalog does not exist and AUTOCREATECATALOG is not
specified, SQL table synchronization fails.
COMPRESS | NO COMPRESS
enables or disables compression of the file set prior to being sent to the
destination system.
This option overrides the global parameter [AUTO]SYNCCOMPRESS.
KEEPNOPURGEUNTIL | NO KEEPNOPURGEUNTIL
specifies that the NOPURGEUNTIL attribute of a source SQL table or
alternate index is preserved (or not preserved) on the destination. If
KEEPNOPURGEUNTIL is specified, no further synchronization will be
successful until the NOPURGEUNTIL period has elapsed.
The default is NO KEEPNOPURGEUNTIL. Unless KEEPNOPURGEUNTIL is
specified, AutoSYNC does not propagate the NOPURGEUNTIL attribute to
the destination table, to insure that future synchronizations will be possible.
KEEPNOPURGEUNTIL is not supported for Enscribe files, consistent with
FUP and RESTORE behavior.
MAPNAMES mapnames-file | NO MAPNAMES
specifies the mapping of a source file set to a destination file set and catalog
name mapping.
Note. Compression is CPU-intensive and can reduce total throughput unless the
connection between source and destination systems is slow.
