Urgent Help Req.: Exception=ORABPEL-11162 Error while reading native data

Question

Hi All,
I am getting below error: Exception=ORABPEL-11162
Error while reading native data.
[Line=6, Col=7|http://forums.oracle.com/forums/] Not enough data available in the input, when trying to read data of length "22" for "element with name PurOrderNum" from the specified position, using "style" as "fixedLength" and "length" as "22".
Ensure that there is enough data from the specified position in the input.
Let me also give you the brief scenario of what I am trying to achieve.
INTERFACE FUNCTIONING:_
I have an interface which reads the records in a file in a chunk through ChunkRead adapter and and after one successful reading if chunk it calls the DB adapter to insert the records in the table.
Now these records are committed and next chunk is read and the process goes on till all the records are read.
After this the API is called which does the processing of these records.
Inserting records in the DB is a XA transaction which means if anything goes wrong while inserting the data, the records which are added earlier are rolled back.
ISSUE:_
Now the issue comes when I do the negative testing. Since my file is based on fixed length schema., I change the length of last record from 15 to 13. (say total are 10 records)
Now what happens is when chunkread tries to read the record of 15 length it gets only 13 characters and hence ignores the records.
But the chunkread reads all other 9 records correctly and sends this to DB adapter which now inserts them correctly in the DB.
But being a global transaction I want that if any record is missing from DB in comparison to those in file then whole transaction should roll back.
So I am unable to make this whole process as global transaction. This is because the ChunkRead adapter inspite of detecting the error doesn’t throw it back.
Moreover if this problem occurs in say next chunk then also I am unable to find out how to rollback the whole transaction. Because the first chunk was correct.
So basically two concerns are there:+
How to detect that chunkread adapter has missed one record?+
Secondly, If it’s detected then how should I rollback the transaction that caused earlier records to enter into database?+
Please let me know if anyone has faced this issue earlyer and how it got resolved. Any pointers regarding this would be of great help.
Also attached is the chunkread log for reference.

Answer 1

Just a thought, you could set the terminator for the last field as {eol} instead of length, this means that it should read the last field regardless of the length.
Depending on the logic of Db adapter the error could be traped due to incorrect length.
If the file starts each row with a constant(s), e.g. 01 then you can terminate the previous line on that, this is the better option but relys on the file format.
The other option is a little thing call compensation, ouch. Basically this allows you to back out commited rows but you have to provide all the logic, it is generally something people avoid because of the complexity.
cheers
