Without dictionary, AUL cannot recover rows to dmp format. But we could manually create them. We will talk about objects information stored in "AULOBJ.TXT" file, the file name must be in upper case under Linux/Unix. The text file should contains the following columns (split by ",") :
1, Object ID
2, User ID
3, Object Name
4, Sub-Object Name, partition or sub-partition name
5, Object Type ID
If you have system tablespace left, it could be generated by "unload table obj$;" command, for example:
9756,5,CUST_INFO,,2
9786,5,FILE$,,2
9776,25,TEST,,2
9787,5,DMPTEST,,2
For the object type column, you could check the SQL definition of view "DBA_OBJECTS", if you have AnySQL installed on your computer, just run "SOURCE DBA_OBJECTS" to get the view's SQL definition.
