SCHEDULE_HEADER structure

The SCHEDULE_HEADER structure is used to contain the replication schedule data for a replication source. The SCHEDULE structure contains an array of SCHEDULE_HEADER structures.

Syntax


typedef struct _SCHEDULE_HEADER {
  ULONG Type;
  ULONG Offset;
} SCHEDULE_HEADER, *PSCHEDULE_HEADER;

Members

Type

Contains one of the following values that defines the type of schedule data that is contained in this structure.

SCHEDULE_INTERVAL

The schedule contains a set of intervals. The Offset member contains the offset to an array of bytes with SCHEDULE_DATA_ENTRIES elements. Each byte in the array represents an hour of the week. The first hour is 00:00 on Sunday morning GMT.

Each bit of the lower four bits of each byte represents a 15 minute block within the hour that the source is available for replication. The following table lists the binary values and describes each bit of the lower four bits of the hour value.

Binary valueDescription

1000

The source is available for replication from 0 to 14 minutes after the hour.

0100

The source is available for replication from 15 to 29 minutes after the hour.

0010

The source is available for replication from 30 to 44 minutes after the hour.

0001

The source is available for replication from 45 to 59 minutes after the hour.

 

These bits can be combined to create multiple 15 minute blocks that the source is available. For example, a binary value of 0111 indicates that the source is available from 0 to 44 minutes after the hour.

The upper fours bits of each byte are not used.

SCHEDULE_BANDWIDTH

Not supported.

SCHEDULE_PRIORITY

Not supported.

Offset

Contains the offset, in bytes, from the beginning of the SCHEDULE structure to the data for this schedule. The size and form of this data depends on the schedule type defined by the Type member.
