Creating a Schedule Object
Defines a schedule for replication.
schedule_create schedule=Schedule [ interval=IntervalSize ]
[ type=<manual|interval|max|time> ]
Parameters:
Name Type Description Mandatory Default
schedule Object name The name of the
schedule
Y N/A
interval N/A A value that
indicates the
interval for
asynchronous
mirroring. Format:
hh:mm [ :ss ].
N 00:10[:00]
type Enumeration A value that
indicates the
schedule type for
asynchronous
mirroring. Can be
Manual or Interval
N interval
This command creates a schedule definition. Schedules can be referenced to when
specifying asynchronous mirroring couplings.
Limitations:
v Schedule must be one of the following: 00:00:30, 00:01, 00:02, 00:05, 00:10, 00:15,
00:30, 01:00, 02:00, 03:00, 06:00, 08:00, 12:00.
v The system features a predefined schedule object with a non-user-configurable
interval of 20 seconds, named min_interval.
The Type parameter:
v Prior to the introduction of this parameter, each asynchronous mirror could be
configured with an automatic schedule whose interval specified how often a
replication point and a corresponding replication process (sync job) should be
automatically created. It was also possible to instruct the system to create a
manual replication point and a corresponding sync job for a mirror using a
dedicated XCLI command (mirror_create_snapshot). Finally, a single predefined
schedule named 'Never' with no interval settings was provided for mirrors that
only required manual sync job creation. Introducing this parameter, it is also
possible to define multiple custom, user-configurable manual schedules. The
creation of consistent, identical replication points for all mirrors set with such
schedule as well as corresponding sync jobs can be triggered using a dedicated
new XCLI command (schedule_create_tick) specifying the schedule name as an
argument. This facilitates external/scripted replication control for mirrors
sharing the same schedule, without requiring them to be interval-based.
v The type Interval specifies that synchronization jobs for a mirror assigned the
schedule will be triggered automatically based on the specified interval; the type
