Transaction Commands
Transactions are used in a manner similar to the other subsystems.
We create a handle to the transaction and then use it for a variety
of operations. Some of the transaction commands use the environment
instead. Those are presented first. The transaction command
handle returned is the handle used by the various commands that can be
transaction protected, such as cursors.
> <env> txn_checkpoint [-kbyte kb] [-min min]
This command causes a checkpoint of the transaction region. It
is a direct translation of the txn_checkpoint
function.
It returns either a 0 (for success), a DB error message or it throws a
Tcl error with a system message. The arguments are:
-
-kbyte causes the checkpoint to occur only if kb kilobytes
of log data has been written since the last checkpoint
-
-min causes the checkpoint to occur only if min minutes
have passed since the last checkpoint
> <env> txn_stat
This command returns transaction statistics. It is a direct translation
of the txn_stat function.
It will return a list of name/value pairs that correspond to the DB_TXN_STAT
structure.
> <txn> id
This command returns the transaction id. It is a direct call to
the txn_id function. The
typical use of this identifier is as the locker value for
the lock_get and lock_vec
calls.
> <txn> prepare
This command initiates a two-phase commit. It is a direct call
to the txn_prepare function.
It returns either a 0 (for success), a DB error message or it throws a
Tcl error with a system message.
