How onunload and onload Work

The onunload utility unloads data from a database. The onunload utility writes a database or table into a file on tape or disk. The onunload utility unloads the data in binary form in disk-page units, making this utility more efficient than dbexport. You can use the onunload utility to move data between computers that have the same version of the database server.

Note:
You cannot use onunload and onload to move data between different versions of Dynamic Server.

The onload utility loads data that was created with the onunload command into the database server. The onload utility creates a database or table in a specified dbspace. The onload utility then loads it with data from an input tape or disk file that the onunload utility creates.

During the load, you can move simple large objects that are stored in a blobspace to another blobspace.
