Description
Set the application's method to be called during transaction abort
and recovery.  This method must return 0 on success and either
errno or a value outside of the Berkeley DB error name space on
failure.  It takes four arguments:
- dbenv  
- A Berkeley DB environment.
- log_rec
- A log record.
- lsn
- A log sequence number.
- op
- One of the following values:
- Db.DB_TXN_BACKWARD_ROLL
- The log is being read backward to determine which transactions have been
committed and to abort those operations that were not, undo the operation
described by the log record.
- Db.DB_TXN_FORWARD_ROLL
- The log is being played forward, redo the operation described by the log
record.
- Db.DB_TXN_ABORT
- The log is being read backwards during a transaction abort, undo the
operation described by the log record.
 
The DbEnv.set_tx_recover interface may only be used to configure Berkeley DB before
the DbEnv.open interface is called.
The DbEnv.set_tx_recover method throws an exception that encapsulates a non-zero error value on
failure.
Errors
- EINVAL
- An invalid flag value or parameter was specified.
Called after DbEnv.open was called.
