NAME
class_save_database - write the in-memory class database to disk
SYNOPSIS
#include <apar_types.h> #include <sys/class.h>
class_save_database(
class_apar_handle_t handle,
char *dbase_name );
LIBRARY
Class Scheduling Library (libclass.a)
This library is not available as a shared library.
PARAMETERS
The partition descriptor returned by class_open(). An optional path‐
name in which the database will be saved.
DESCRIPTION
The class scheduler database is shared in memory by the class_admin
command, the class scheduler daemon, and the runclass command. Adminis‐
trative changes (such as adding a gid to a class) need to be saved to
disk so that the changes are available at the next reboot. Note that
class scheduler administrative changes take effect immediately whether
they are written to disk or not.
If the dbase_name argument is supplied, the database will be written to
the specified pathname. The current database name will be used by
default if dbase_name is null.
Note that the calling process must have root access privileges.
RETURN VALUES
The operation completed successfully. An invalid partition handle was
specified. The dbase_name size limit is exceeded. Error in writing
the file, indicated by ERRNO
