Question

dear experts,
I have same problem as described in thread
CSALTER finished unsuccessfully in 11g
My csscan output has two tables, one with 22 and other with 4 rows show lossy data.
and csalter failed.
What is reasonable approach to take care of this situation.
delete that data?
Please provide some feedback. I deeply appreciate it.
log from csalter:

I think for application tables I can increase the size of a column should fix problem of 2 tables.
but how to fix problem of SYS tables. or since it says they are convertible so I should leave it alone.

Answer 1

As per Metalink Doc ID:335147.1
To use Csalter the Csscan output needs to be:
* changeless for all CHAR VARCHAR2, and LONG data (Data Dictionary and User)
* changeless for all USER CLOB
* convertible and changeless for all Data Dictionary CLOB
My Csscan output satisfied all the above said needs. The error reports of the CSScan are 'clean', there is no convertible (*except Data Dictionary CLOB data), truncation or lossy data in the database.
*Data Dictionary CLOB datas will be handled by Csalter.
But even then the execution of CSALTER finished unsuccessfully.
regards,
Nataraj
