At the time you import LOB data specifying the LOBSINFILE file type modifier, the server code page should be the same as the page of database code else, SQL3525N error is returned: the CODEPAGE option is incompatible with the LOBSINFILE option.
So in order to solve out this very situation
Use the DB2 load utility.
If your IMPORT command is:
import from myfile.ixf of ixf replace into mytable
then you can try using the following command:
load from myfile.ixf of ixf modified by codepage=1208 replace into mytable
