Restrictions
Fast Path Online Restructure/EP is designed to handle database changes with a minimum outage time; it is not designed to handle application program changes. As a result, the following restrictions apply:
You cannot insert a segment within the hierarchical path of an existing segment.
You cannot remove an existing segment.
You cannot add or remove a key sequence field on a segment.
You cannot change a direct dependent segment to an SDEP or an SDEP to a direct dependent segment.
SDEP marker segments are not supported.
Note
If you are using expressions to modify the affected segment, you can make the following changes:
You can modify the length of a key sequence field.
You can modify a segment from fixed length to variable length or from variable length to fixed length.
You can modify the length of a fixed length segment.
For variable-length segments, you can increase the minimum length or decrease the maximum length.
