Question
Do you have any idea about ROW-CHAINING ? How will you resolve the issue if there is row- chaining in a table ?
Answers
When a row NO LONGER FITS WITHIN THE DATABLOCK, it is stored in more than one database block, and that therefore have several row pieces.
Resolving: Use ANALYZE to identify chained rows and also provides statistics on the chained rows. Eg: ANALYZE ledger LIST CHAINED ROWS INTO CHAINED_ROWS:
(CHAINED_ROWS is a user defined table)
For creating chained_rows run the UTLCHAIN.SQL script.   Your Comment
