oracle streams - how to get last successfully applied scn for crashed apply?

Question

I have a downstream Streams replication set up between Oracle 9i (source) and Oracle 11g (destination). The process is still in developlment stage, so the whole setup is not stable yet.

Sometimes my apply procedure at destination database fails. Say, with a error like this:

APPLY_NAME                     STATUS   RULE_SET_NAME                  ERROR_MESSAGE
------------------------------ -------- ------------------------------ ----------------------------------------

                                                                       ORA-25455: evaluation error for rule set
                                                                       : STRMADMIN.RULESET_APPLY_LCR_SUN, evalu
                                                                       ation context: SYS.STREAMS$_EVALUATION_C
                                                                       ONTEXT
                                                                       ORA-00600: internal error code, argument
                                                                       s: [knlqany2lcr235], [22629], [ORA-22629
                                                                       : OCIAnyData is null
                                                                       ], [], [], [], [], [], [], [], [], []

I need to know the last source database SCN it was able to apply before failing.

DBA_APPLY.MAX_APPLIED_MESSAGE_NUMBER shows me something only in case apply process is stopped normally.

Any ideas?
