Berkeley DB: DbEnv::set_panicstate
DbEnv::set_panicstate
|
 
|
#include <db_cxx.h>
static int
DbEnv::set_panicstate(int panic);
Description
Toggle the Berkeley DB panic state. Setting panic to a non-zero value
causes Berkeley DB to refuse attempts to call Berkeley DB functions with the
DB_RUNRECOVERY error return.
The DbEnv::set_panicstate interface affects the entire application, not a single
database or database environment.
The DbEnv::set_pageyield interface may be used to configure Berkeley DB at any time
during the life of the application.
The DbEnv::set_panicstate 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
The DbEnv::set_panicstate method may fail and throw an exception or return a non-zero error for the following conditions:
- EINVAL
- An invalid flag value or parameter was specified.
The DbEnv::set_panicstate method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
If a catastrophic error has occurred, the DbEnv::set_panicstate method may fail and either
return DB_RUNRECOVERY or throw an exception encapsulating
DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail
in the same way.
