Warning: ifx_pconnect : E [SQLSTATE=IX 000 SQLCODE=-439]
--------------------------------------------------------
I don't use [ifx_pconnect] function in my scripts.

The reasons of -439 error code are as follows.(finderr -439)
(I can't understand the means of thr descriptions.)
--------------------------------------------------------
You attempted to call an SQL routine or attempted to execute an SQL
statement within a signal handling function/routine or a callback
function/procedure. Use only the sqldone() and sqlbreak() library
functions inside your INFORMIX-ESQL/C callback function. Use only the
ECO-SQD and ECO-SQB library routines inside your ESQL/COBOL callback
procedure. In addition, if you want to unregister your callback
function in INFORMIX-ESQL/C, you can invoke the sqlbreakcallback()
callback registration function within your callback procedure. If you
want to unregister your callback procedure in ESQL/COBOL, you can
invoke the ECO-SQBCB callback registration routine within your callback
procedure.
