dealing with support

It is quite a long time I did shot the pianist in my blog… probably patience and perseverance are better than aggressive behavior, but today I have been transfixed by an answer from metalink.

Sometimes the issues I submit are a bit exotic but there it was a join with one view using one function and dual returning wrong results. Reproducible at will on any db and below.

After 2 weeks the helpful engineer told me it is fixed with patch 6471020 and in 11g. I asked if he tried it but he said no. As the patch is not available on my platform I asked if could try it but then he came back with an amazing workaround he became from an ARE (advanced resolution engineer) :

Remove the function from the view.


.plz dump file

What are those .plz dump files in my user dump directory ?

-rw-r--r--   1 oracle   dba        15168 Oct  6 14:34 _anon__3ca8c5e38__AB.plz
-rw-r-----   1 oracle   dba        15883 Oct  6 14:45 db01_ora_10061.trc

-rw-r--r--   1 oracle   dba        15168 Oct  6 14:47 _anon__3c8651198__AB.plz

let’s check one, briefly :

*** ASSERT at file pdw4.c, line 2080; Type 0xffffffff7d79fb40 has no MAP method.
Source Location = _anon__3d2474b28__AB[1, 7]

  CG            = 0

It is a kind of dump file, apparently. I could not find details on metalink. I generate the one above in sparc with the following code

create or replace type t1 as object (x number)
create or replace type t2 as table of t1
exec if t1(1)member of t2()then null;end if

BEGIN if t1(1)member of t2()then null;end if; END;
Error at line 10
ORA-06550: line 1, column 7:
