# DbLockTab.close

    import com.sleepycat.db.*;

    public void close()
        throws DbException;

# Description

The DbLockTab.close method closes the lock table.

The DbLockTab.close method does not release any locks still held by the closing process, providing functionality for long-lived locks.

In addition, if the dir argument to DbLockTab.open was NULL and dbenv was not initialized using DbEnv.appinit, all files created for this shared region will be removed, as if the DbLockTab.unlink method were called.

In multi-threaded applications, only a single thread may call the DbLockTab.close method.

The DbLockTab.close method throws an exception that encapsulates an errno on failure.

# Errors

If a fatal error occurs in Berkeley DB, the DbLockTab.close method may fail and throw a DbRunRecoveryException, at which point all subsequent database calls will also fail in the same way.

The DbLockTab.close method may fail and throw an exception for any of the errors specified for the following Berkeley DB and C library functions: abort(3), close(3), fcntl(3), fflush(3), fprintf(3), free(3), getpid(3), memset(3), munmap(3), shmctl(3), shmdt(3), strlen(3), unlink(3), vfprintf(3), and vsnprintf(3).
