Forms: Copy or Move Stream Data
From a
Stream Set List
it is possible to copy or move the
Stream Sets
to another
Stream
by dragging either the
icon (representing all data i.e. all
Stream Sets)
or a selection of
Stream Sets
onto another
Stream
or
Stream Set List.
After this drag/drop operation, the options form described here will appear to allow you
to specify whether data should be copied or moved.
Note that this operation can only be used to copy or move data to a Stream which had been originally been copied from the source Stream. CenterView currently matches the internal field names of the Stream Attributes in order to work out how to reattach the data to the target Stream.
CenterView will warn you if the copy or move operation is likely to result in data being removed e.g.
because an
Attribute
does not exist on the target
Stream.
To reduce the
possibility of losing data, we recommend always using the copy operation so that the original data
is preserved. This data can then be removed later if needed using the
rollback
option.
The move option is provided for cases when there is a very large set of data that
needs to be transferred to the target
Stream
and there is either limited space available on the CenterView database or the copy will take longer than
you are willing to wait. Note that moving data happens immediately however the time take to copy the
data is determined by the speed of your CenterView database server.
Form: Copy or Move Stream Data
The form gives a graphic view of what will happen when the
icon is pressed:
| Item | Description |
|---|---|
| Source Stream | The name of the Stream which contains the data.. |
| Arrow | Indicates the direction of the copy or move operation. |
| Target Stream | The name of the Stream to which the data will be moved or copied. |
| Action Button |
The action that will be carried out when the
icon is pressed.
|
| Stream Set List |
This form shows the list of
Stream Sets
which were dragged and dropped as a reminder of the
Stream Sets
that will be copied. If you decided to copy all data by dragging and dropping the
icon on the
Stream Set List
then the Stream Set List will not be shown here.
|
When the
icon is pressed, CenterView first checks that the operation is valid and if there are any issues that
you need to confirm before proceeding. E.g. after pressing
if the
Stream
configurations match completely, CenterView will carry out the requested operation. However
if there are any differences e.g. a missing attribute on the target
Stream
CenterView will request confirmation from you before proceeding.
CenterView will create log entries for the move or copy operation in the System Console.
