#include <db_cxx.h>
int DbEnv::set_verbose(u_int32_t which, int onoff);
Description
The DbEnv::set_verbose method turns additional informational and
debugging messages in the Berkeley DB message output on and off. If
onoff is set to
non-zero,
the additional messages are output.
The which parameter must be set to one of the following values:
- DB_VERB_CHKPOINT
- Display checkpoint location information when searching the log for
checkpoints.
- DB_VERB_DEADLOCK
- Display additional information when doing deadlock detection.
- DB_VERB_RECOVERY
- Display additional information when performing recovery.
- DB_VERB_WAITSFOR
- Display the waits-for table when doing deadlock detection.
The DbEnv::set_verbose interface may be used to configure Berkeley DB at any time
during the life of the application.
The DbEnv::set_verbose
method either returns a non-zero error value or throws an exception that
encapsulates a non-zero error value on failure, and returns 0 on success.
Errors
- EINVAL
- An invalid flag value or parameter was specified.
