Problem summary
USERS AFFECTED: All PROBLEM DESCRIPTION: Inserting large amount of multi-byte character data into a CLOB column can result in data corruption. The result data in the CLOB column in such case would contain characters 0xFC. PROBLEM SUMMARY: The problem can occur when working with large lob data (>128kB). The lob data is processed in chunks as they are passed by the client. When an internal lob processing buffer containg the data chunks is full and there is still data to process, the lob data is translated by codepage conversion functions, moved into a temporary table and next chunk of data is processed. In this particular defect situation the buffer full condition occurs in the middle of the multi-byte character. The last byte in the buffer is not valid multi-byte character so it suppose to be remembered and used as the first character of the following chunk. Due to a defect this dangling character is dropped, causing all the next multi-byte characters in the following chunk to be byte shifted. Good data: 006A0061 00760061 002E006C 0061006E .j.a.v.a...l.a.
