OSS File Synchronization

Displaying OSS Files and Directories
Another side effect of the source and destination timestamps inherent mismatch is that
the TIMEEXACT option is ignored for symbolic links.
Displaying OSS Files and Directories
For convenience, the AUTOSYNC command LS can be used to display information
and statistics on OSS files, directories, and directory trees. The AUTOSYNC command
LS is equivalent to the OSS shell command ls and has several options. For example:
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
AutoSYNC propagates the standard file and directory security.
Unlike Guardian, OSS does not allow AutoSYNC to "give" ownership of files to another
user, or to set the group ID to another group, unless the user is SUPER.SUPER. The
user always becomes the owner of the files on the destination file set, unless the user
is SUPER.SUPER. This means each user can only synchronize their own files unless:
AutoSYNC 9? ls -l /home/guser/sally;
/home/guser/sally:
