Db.remove

import com.sleepycat.db.*;
public void remove(String name, String subname, int flags)
throws DbException;
Description
The Db.remove interface removes the database (or subdatabase)
represented by the name and subname combination.
If no subdatabase is specified, the physical file represented by
name is removed, incidentally removing all subdatabases
that it contained.
No reference count of database use is maintained by Berkeley DB. Applications
should not remove databases that are currently in use.
The flags parameter is currently unused, and must be set to 0.
The Db.remove
method throws an exception that encapsulates a non-zero error value on
failure.
Environment Variables
- DB_HOME
- If the dbenv argument to db_create was initialized using
DbEnv.open the environment variable DB_HOME may be used
as the path of the database home for the interpretation of the dir.
Specifically, Db.remove is affected by the configuration string value of
DB_DATA_DIR.
Errors
If a fatal error occurs in Berkeley DB, the Db.remove method will fail and throw a
DbRunRecoveryException, at which point all subsequent database
calls will fail in the same way.
In addition, the Db.remove method may fail and
throw an exception
for errors specified for other Berkeley DB and C library or system methods.
