OCITypeByName problem

I am using Oracle 8.0.6 on HP-UX, in my application next statemrnt invoke about 100 times in different places for different type names and next give the error: "OCI-22303: type "T_RIGHT" not found", although this type exists and earlier invorke for this type name was successfully. Why this maybe ?

status = OCITypeByName(env, err,

          svc, (text *) 0,


          (ub4) 0, (text *)typeName.c_str(),

          (ub4)typeName.length(),

          (CONST text *) 0, (ub4) 0,

          OCI_DURATION_SESSION, OCI_TYPEGET_ALL,
          &tdo);
