Comparing Source and Destination File Sets
Comparing Source and Destination File Sets
A source file or directory is synchronized if the source file or directory was modified
after the destination file or directory was last modified. Timestamp comparisons
account for differences in time zones and system clocks. Files that have the same
modification timestamp are never synchronized.
Exceptions:

If the TIMEEXACT option is specified, a source and destination file that do not
have the same modification timestamp are synchronized, even if the destination
file was modified after the source file.
As mentioned above in Modification Timestamp of Symbolic Links , TIMEEXACT is
ignored for symbolic links.

The RENAMEOPEN option is not supported for OSS files. If a destination file is
open at the time of the synchronization, it will not be synchronized but a warning is
written to the log file and synchronization continues with the next file or directory.
The BACKUP[INFILE] for OSS file sets is an entry-sequenced file that contains the
names of the files and directories to be synchronized in addition to internal file
information. Specify the
KEEPB[ACKUPINFILE] option to preserve this file for
debugging purposes.
Ownership and Security
Ownership of OSS Files
AutoSYNC propagates the standard file and directory security.
Unlike Guardian, OSS does not allow a syncuser to "give" ownership of files to another
user, or to set the group ID to another group, unless the syncuser is SUPER.SUPER. If
a syncuser has read permissions on a source file set and write permissions on the
destination file set, the files can be synchronized but the syncuser performing the
synchronization becomes the owner of the file set on the destination.
To preserve the ownership of an OSS file set on the destination:

The syncuser must be the owner of the source file set or SUPER.SUPER, and

if the syncuser is SUPER.SUPER and the destination is on a remote system, the
remote destination synchronization process must be licensed to allow it to run as a
local process, as described in
Licensing Synchronization Processes on page 2-11
Security of OSS Files
The security of the destination file or directory is the same as the source file or
directory, except for WRITE access. WRITE access on the destination files is set to
allow subsequent synchronizations, much like PURGE security for Guardian files.
