Upload

An upload updates the model in the CSE. If the upload is without check in, the upload usually runs faster because the object status is not being changed. For an upload with check in, the following occurs:

• All of the transactions in the transaction file are processed.
• A commit occurs.
• The DCKOID row is deleted.
• All objects in the subset are checked in or deleted from DSUBEX with periodic commits taken.

If the upload abends during the process of checking in the objects, the next download of the model or any subset of that model cleans up the partial checkout.

Since upload is an update process, the encyclopedia only allows limited access to the model while the model is being updated. An upload cannot run while a download or code generation is occurring in that model. The only activities that can run simultaneously with an upload in the same model are other uploads or overriding, renaming, deleting or copying another subset. Locks occur as objects are inserted and deleted, properties are modified, and associations are added and deleted.

If the upload fails, you cannot continue to work on the subset until the upload is completed. This may be important when you plan for an upload.
