INCORRECT EXPORTED DATA LENGTH FOR THE EXPORT COMMAND SPECIFYING MODIFIED BY CODEPAGE=954 |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
The exported data length may be incorrect when "MODIFIED BY
codepage=954" is specified to the export command.
Note that the issue may happen when the system codepage is UTF-8
for Japanese language (ex. JA_JP.UTF-8 for AIX) but it does not
happen for Ja_JP (SJIS) or ja_JP (EUC JP).
The following is an example of reproduction scenarios on AIX.
Though the correct data length should be 15 bytes, the exported
data is expanded with trailing x'20' characters.
$ export LANG=JA_JP.UTF-8

| Local-Fix: |
Use DB2CODEPAGE instead of "MODIFIED BY".
export DB2CODEPAGE=954
It should be done before connecting to the database. |
