EILSEQ_COMPAT_MODE configuration parameter

1 = Informix does not validate incoming character sequences.

takes effect
After you edit your onconfig file and restart the database server.

Usage

If you set the EILSEQ_COMPAT_MODE configuration parameter to 0, only valid byte sequences can be inserted to the database.

The EILSEQ_COMPAT_MODE configuration parameter prevents a 202 error in these conditions:

  • When data is being retrieved from the database.
  • When an invalid character is at the end of the string and is a partial character.
