Regards,
MeeranIt appears that SQL_TYPE_MISMATCH is set to Y in V$SQL_SHARED_CURSOR to indicate that the SQLTYPE in V$SQL changed. For example (note that this SQL statement specifiies a specific SQL_ID):
SELECT
SS1.SQL_TEXT,
SS1.SQL_ID,
SS1.CHILD_NUMBER,
SS1.SQLTYPE,
SS2.CHILD_NUMBER,
SS2.SQLTYPE
FROM
V$SQL SS1,
V$SQL SS2
WHERE
SS1.SQL_ID=SS2.SQL_ID
AND SS1.SQLTYPE< SS2.SQLTYPE
AND SS1.SQL_ID='39tw34mramfdv'
ORDER BY
SS1.SQL_TEXT,
SS1.CHILD_NUMBER;
SQL_TEXT SQL_ID CHILD_NUMBER SQLTYPE CHILD_NUMBER SQLTYPE
SELECT BANNER FROM V$VERSION 39tw34mramfdv 0 2 1 6Now to check V$SQL_SHARED_CURSOR:
SELECT
FROM
V$SQL_SHARED_CURSOR
WHERE
SQL_ID='39tw34mramfdv'
ORDER BY
CHILD_NUMBER;
SQL_ID CHILD_NUMBER U S O O S L S E B P I S T A B D L T R I I R L I O S M U T N F A I T D L D B P C S R P T M B M R O P M F L
39tw34mramfdv 0 N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N
39tw34mramfdv 1 N Y N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N NThe documentation is not very clear regardiing the SQLTYPE column in V$SQL:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2113.htm
"SQLTYPE: Denotes the version of the SQL language used for this statement"
I have not been able to find additional clarity what the various SQLTYPE values indicate - the column was added in Oracle Database 9i R2 (edit: column exists in 9i R1 based on output that appears in the book "Optimizing Oracle Performance", it appears that I misread the "What's New Documentation"). I see values of 0, 2, and 6 for the SQLTYPE of the same query. I would be interested to know what causes the different values to appear (with and without ANSI support?).

Gather_Plan_Statistics + DBMS_XPLAN A-rows for parallel queries
Looks like gather_plan_statistics + dbms_xplan displays incorrect A-rows for parallel queries. Is there any way to get the correct A-rows for a parallel query?
Version details:
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi on HPUX
Create test tables:
-- Account table
create table test_tacprof
parallel (degree 2) as
select object_id ac_nr,
object_name ac_na
from all_objects;
alter table test_tacprof add constraint test_tacprof_pk primary key (ac_nr);
-- Account revenue table
create table test_taccrev
parallel (degree 2) as
select apf.ac_nr ac_nr,
fiv.r tm_prd,
apf.ac_nr * fiv.r ac_rev
from (select rownum r from all_objects where rownum <= 5) fiv,
test_tacprof apf;
alter table test_taccrev add constraint test_taccrev_pk primary key (ac_nr, tm_prd);
-- Table to hold query results
create table test_4accrev as
select apf.ac_nr, apf.ac_na, rev.tm_prd, rev.ac_rev
from test_taccrev rev,
test_tacprof apf
where 1=2;

INSERT INTO test_4accrev

A-rows are zero execpt for final step.I'm sorry for posting following long test case.
But it's the most convenient way to explain something. :-)
Here is my test case, which is quite similar to yours.
Note on the difference between "parallel select" and "parallel dml(insert here)".
(I know that Oracle implemented psc(parallel single cursor) model in 10g, but the details of the implementation is quite in mystery as Jonathan said... )

I am finding this bug 11930680 is affecting my APEX 4.1.1 install.. I am Running 11.2.0.1 on Redhat linux
eg
I get 21 versions of this SQL in APEX_040100 in v$sql_shared_cursor, with reasons AUTH_CHECK_MISMATCH LANGUAGE_MISMATCH
SELECT SHORTCUT_NAME, ID
FROM WWV_FLOW_SHORTCUTS
WHERE FLOW_ID = :B3 AND (BUILD_OPTION IS NULL OR (BUILD_OPTION > 0 AND (:B2 IS NULL OR INSTR(:B2 ,':'||BUILD_OPTION||':') = 0) ) OR (BUILD_OPTION < 0 AND (:B1 IS NOT NULL AND INSTR(:B1 ,':'||(0-BUILD_OPTION)||':') = 0) ) )
ORDER BY SHORTCUT_NAMEAny many, many other APEX_040100 SQLs having same issue, which I think is slowing down APEX
Should I
- Grant MERGE ANY VIEW to SYS (as per http://magnusjohanssontuning.wordpress.com/2012/08/01/cursor-not-shared-for-different-users/)
- set optimizer_secure_view_merging=false (as per oracle Workaround)
Anyone have similar problems?
