The default is On, because certain job servers and third-party applications
cannot function without changing to client rights. To determine whether the
job server can function without client rights, refer to the documentation that
comes with the job server.
Using the Transaction Tracking System
NetWare includes a transaction-monitoring feature called the Transaction
Tracking System
TM
(TTS
TM
). If you flag a file as transactional, TTS can
prevent corruption of records in the file by backing out of incomplete
transactions and keeping a record of backed-out data.
NOTE: A file flagged as transactional cannot be deleted or renamed.
TTS can also back out file truncations or extensions and multiple changes to
the same data area during a single transaction. TTS can even back out
interrupted backouts if the NetWare server fails in the middle of backing out
transactions.
But TTS cannot protect against these types of failures for any type of
application that issues record-locking calls and stores information in records,
including traditional databases, some electronic mail applications, and some
workgroup appointment schedulers.
Files that aren’t organized into discrete records (such as word processing files)
aren’t protected by TTS.
Transactions on a network can be saved improperly in any of the following
situations:
 Power to a server or a workstation is interrupted during a transaction
 Server or workstation hardware fails during a transaction (for example, a
parity error on a network board)
 A server or workstation hangs (a software failure) during a transaction
 A network transmission component (such as a hub, a repeater, or a cable)
fails during a transaction
If the server fails and the file has been flagged transactional, TTS backs out
the transaction when the server comes up again. If a workstation or network
transmission component fails, TTS backs out the transaction immediately.
