Fault Tolerance and File Recovery
To configure a scheduled synchronization, a user must be added to the AutoSYNC
system. An AutoSYNC administrator enables users to schedule synchronizations and
can specify a maximum priority and select CPUs that the user should use. The
AutoSYNC administrator can also suspend and activate a user without changing the
user’s configuration.
Fault Tolerance and File Recovery
Scheduled synchronizations are managed by a fault-tolerant process pair. CPU and
media failures, as well as network outages, are dealt with gracefully; synchronization
proceeds whenever the required resources are available. The only operational
requirement is to start the AutoSYNC monitor process following a cold load.
If a process, CPU, media, or network failure interrupts a synchronization, AutoSYNC
will restore the previous version of any Enscribe file being replaced before terminating
the operation.
Synchronization Options
There are numerous options to allow you to perform special operations when
synchronizing files; these include:
•
Purge files in the destination file set that do not exist in the source file set.
•
Purge subvolumes in the destination volume that do not exist in the source volume.
•
Replace files that are currently in use, such as executing object files, through
automatic renaming.
•
Specify the owner and security of synchronized files.
•
Change file security to allow network access to synchronized files.
•
Specify the SQL catalog of tables that are synchronized.
•
Include or exclude ZZ (temporary) files.
•
Include or exclude audited files.
•
Specify files to be excluded from synchronization.
•
Include files opened for update.
•
Compress data to reduce network bandwidth usage.
•
Specify a TACL command or macro or an OSS shell command to execute after a
file has been synchronized. This feature is referred to as triggers.
•
Choose synchronization over an Expand link or over a TCP/IP link.
