Oracle Streams error logs not showing timestamp values

Question

When outputting a log of streaming errors on Oracle 10g, the log does not show values for timestamp fields; instead it simply shows "timestamp is SYS.TIMESTAMP" as the old and new value. Is there any way to configure Oracle streams to show the actual timestamp value? We need this information to properly debug the root cause of these streaming errors.

For example, executing the following:

exec strmadmin.print_errors;

Gives us this (truncated) error log:

Answer 1

In case anyone is interested, I found the solution to this problem. Simply replace the "print_any" stored procedure with the following version which outputs the value for timestamp data types:

CREATE OR REPLACE PROCEDURE print_any(data IN ANYDATA) IS
  tn  VARCHAR2(61);
  str VARCHAR2(4000);
  chr VARCHAR2(1000);
  num NUMBER;
  dat DATE;
  rw  RAW(4000);
  res NUMBER;
BEGIN
  IF data IS NULL THEN
    DBMS_OUTPUT.PUT_LINE('NULL value');
    RETURN;
  END IF;
  tn := data.GETTYPENAME();
  IF tn = 'SYS.VARCHAR2' THEN
    res := data.GETVARCHAR2(str);
    DBMS_OUTPUT.PUT_LINE(SUBSTR(str,0,253));
  ELSIF tn = 'SYS.CHAR' then
    res := data.GETCHAR(chr);
    DBMS_OUTPUT.PUT_LINE(SUBSTR(chr,0,253));
  ELSIF tn = 'SYS.VARCHAR' THEN
    res := data.GETVARCHAR(chr);
    DBMS_OUTPUT.PUT_LINE(chr);
  ELSIF tn = 'SYS.NUMBER' THEN
    res := data.GETNUMBER(num);
    DBMS_OUTPUT.PUT_LINE(num);
  ELSIF tn = 'SYS.DATE' THEN
    res := data.GETDATE(dat);
    DBMS_OUTPUT.PUT_LINE(dat);
  ELSIF tn = 'SYS.TIMESTAMP' THEN
    res := data.GETTIMESTAMP(dat);
    DBMS_OUTPUT.PUT_LINE(tn || ':' || to_char(dat,'DD-MON-YYYY HH24:MI:SS.FF'));
  ELSIF tn = 'SYS.RAW' THEN
    -- res := data.GETRAW(rw);
    -- DBMS_OUTPUT.PUT_LINE(SUBSTR(DBMS_LOB.SUBSTR(rw),0,253));
    DBMS_OUTPUT.PUT_LINE(tn || ":RAW");
  ELSIF tn = 'SYS.BLOB' THEN
    DBMS_OUTPUT.PUT_LINE(tn || ":BLOB");
  ELSE
    DBMS_OUTPUT.PUT_LINE('typename is ' || tn);
  END IF;
END print_any;
