Hi all,
We'll do a conversion from IMS to Oracle (817). The conversion team wants to move data on Oracle then processed it.
Off course, in the file format, the cobol redefine command is used on a filler field (20 times). There is also a redefine command in a redefine command.
For the younger ones, it means a zone (50 caracters) that can be defined in many ways depending on a key : 2 fields of 25 char or 5 fields of 10 char or ....
The programmers can always use substring to death to work this out but I was wandering if there was a more elegant and a less error prone solution, maybe using a record type or a function ...

Hi Stephane,
How are you loading the data into the Oracle database? Do you use SQL*Loader? Go to the manual and look at the examples, it is quite straightforward defining multiple record layouts, and have them loaded into defferent tables. This can be done based on the record-type indicator which will be in the record. You can handle your redefines and repeating groups with SQL*Loader.
Last year I've written a kind of replication mechanism which replicates a Cobol C-Isam system into an Oracle database on a daily basis. Different record layouts can be stored in differend tables, or in the same table in different columns. The latter I do not recommend. This will giive you a nice headstart converting the data into the ultimate datamodel.
