export NLS_LANG=american_america.utf8
insert into my_test_table (column_1) values ('UNNT0505 UNOO0605 USTR0636 
USSS0710 US`ù^]úM??PP0737 USKK0801 ULWW0828') 
ERROR at line 1: 
ORA-00600: internal error code, arguments: [17147], [0xB728FF8C], [], [], 
[], [], [], [] 
ORA-06512: at "TC.MY_TEST_TABLE_IBR", line 3 
ORA-04088: error during execution of trigger 'TC.MY_TEST_TABLE_IBR' 
  • The trigger code uses COMPOSE function.

create or replace trigger my_test_table_ibr
before insert on my_test_table
for each row
  if COMPOSE(:new.column_1) != :new.column_1 then
  end if;
  • The issue would not occur if specifying a character set other then UTF8 in NLS_LANG (eg. WE8MSWIN1252). Usually the NLS_LANG character set should reflect the setting of the operating system character set of the client (eg. WE8MSWIN1252). Nevertheless ORA-600 [17147] should not occur here, hence this is a bug.
