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

handle
The partition descriptor returned by class_open(). 

dbase_name
An optional pathname 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. Administrative 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

[CLASS_SUCCESS]
The operation completed successfully.

[CLASS_INVAL_PARTITION]
An invalid partition handle was specified.

[CLASS_NAME_TOO_LONG]
The dbase_name size limit is exceeded. 

[CLASS_FILE_FAILURE]
Error in writing the file, indicated by ERRNO
