Which PLAN_HASH_VALUE Appears in V$SQLAREA?

28 03 2012

March 28, 2012

A recent question on the OTN forums asked which PLAN_HASH_VALUE appears in V$SQLAREA when there are multiple child cursors for a single SQL_ID value, when some child cursors have a different execution plan.  Certainly, this bit of information must be in the Oracle Database documentation.  Let’s check the V$SQLAREA documentation for Oracle Database 11.2:

“Numeric representation of the SQL plan for this cursor. Comparing one PLAN_HASH_VALUE to another easily identifies whether or not two plans are the same (rather than comparing the two plans line by line).”

Well, that was not helpful, but it does remind me of something that I saw when I went out for a drive in the countryside this past weekend (all within about a 50 meter radius – click a picture to see a larger view of the picture):

 

OK, now that the initial frustration of not obtaining an answer from the documentation has subsided, let’s put together a quick test case to see if we are able to help the OP find an answer to his question.  We will borrow a slightly modified version of a test script that generates skewed data which was used in another article

CREATE TABLE T1 AS
SELECT
  ROWNUM C1,
  DECODE(ROWNUM,1,1,0) C2,
  LPAD('A',255,'A') C3
FROM
  DUAL
CONNECT BY
  LEVEL<=10000;

CREATE UNIQUE INDEX IND_T1_C1 ON T1(C1);
CREATE INDEX IND_T1_C2 ON T1(C2);

ALTER TABLE T1 MODIFY (C1 NOT NULL, C2 NOT NULL);

EXEC DBMS_STATS.GATHER_TABLE_STATS(OWNNAME=>USER,TABNAME=>'T1',CASCADE=>TRUE,ESTIMATE_PERCENT=>100,METHOD_OPT=>'FOR ALL INDEXED COLUMNS SIZE 254') 

For the initial test (in Oracle Database 11.2.0.2), I will use the BIND_AWARE hint to save Oracle from having to determine that the execution plan could (should) depend on the bind variable value, rather than having to rely on adaptive cursor sharing to eventually obtain the same effect:

SET LINESIZE 120
SET PAGESIZE 1000

VARIABLE V1 NUMBER
EXEC :V1:=1

SELECT /*+ BIND_AWARE */
  C1,
  C2,
  C3
FROM
  T1
WHERE
  C2=:V1;

SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY_CURSOR(NULL,NULL,'TYPICAL'));

SQL_ID  7p4yxrzwwuybt, child number 0
-------------------------------------
SELECT /*+ BIND_AWARE */   C1,   C2,   C3 FROM   T1 WHERE   C2=:V1

Plan hash value: 236868917

SELECT
  PLAN_HASH_VALUE
FROM
  V$SQLAREA
WHERE
  SQL_ID='7p4yxrzwwuybt';

PLAN_HASH_VALUE
---------------
      236868917 

As shown above, the PLAN_HASH_VALUE has a value of 236868917 in V$SQLAREA, which is the same value (shown in the execution plan) of the most recently executed child number.

Let’s repeat the previous SQL statements, this time with a different bind variable value:

EXEC :V1:=0

SELECT /*+ BIND_AWARE */
  C1,
  C2,
  C3
FROM
  T1
WHERE
  C2=:V1;

SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY_CURSOR(NULL,NULL,'TYPICAL'));

SQL_ID  7p4yxrzwwuybt, child number 1
-------------------------------------
SELECT /*+ BIND_AWARE */   C1,   C2,   C3 FROM   T1 WHERE   C2=:V1

Plan hash value: 3617692013

--------------------------------------------------------------------------
| Id  | Operation         | Name | Rows  | Bytes | Cost (%CPU)| Time     |
--------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |      |       |       |    33 (100)|          |
|*  1 |  TABLE ACCESS FULL| T1   |  9999 |  1327K|    33   (0)| 00:00:01 |
--------------------------------------------------------------------------

Predicate Information (identified by operation id):
---------------------------------------------------
   1 - filter("C2"=:V1)

SELECT
  PLAN_HASH_VALUE
FROM
  V$SQLAREA
WHERE
  SQL_ID='7p4yxrzwwuybt';

PLAN_HASH_VALUE
---------------
     3617692013 

As shown above, the execution plan changed, thus the Plan hash value in the execution plan changed to 3617692013, and that change corresponded with the PLAN_HASH_VALUE for the SQL_ID in V$SQLAREA changing to the value 3617692013 – the same value shown in the execution plan for the most recently executed child number.

Let’s trying again without changing the bind variable value to see what happens:

SELECT /*+ BIND_AWARE */
  C1,
  C2,
  C3
FROM
  T1
WHERE
  C2=:V1;

SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY_CURSOR(NULL,NULL,'TYPICAL'));

SQL_ID  7p4yxrzwwuybt, child number 1
-------------------------------------
SELECT /*+ BIND_AWARE */   C1,   C2,   C3 FROM   T1 WHERE   C2=:V1

Plan hash value: 3617692013

--------------------------------------------------------------------------
| Id  | Operation         | Name | Rows  | Bytes | Cost (%CPU)| Time     |
--------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |      |       |       |    33 (100)|          |
|*  1 |  TABLE ACCESS FULL| T1   |  9999 |  1327K|    33   (0)| 00:00:01 |
--------------------------------------------------------------------------

Predicate Information (identified by operation id):
---------------------------------------------------
   1 - filter("C2"=:V1)

SELECT
  PLAN_HASH_VALUE
FROM
  V$SQLAREA
WHERE
  SQL_ID='7p4yxrzwwuybt';

PLAN_HASH_VALUE
---------------
     3617692013 

As shown above, the PLAN_HASH_VALUE in V$SQLAREA remained at the value 3617692013, which is the PLAN_HASH_VALUE of the most recently executed child number.

Let’s switch back to the original bind variable value to see what happens in V$SQLAREA:

EXEC :V1:=1

SELECT /*+ BIND_AWARE */
  C1,
  C2,
  C3
FROM
  T1
WHERE
  C2=:V1;

SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY_CURSOR(NULL,NULL,'TYPICAL'));

SQL_ID  7p4yxrzwwuybt, child number 0
-------------------------------------
SELECT /*+ BIND_AWARE */   C1,   C2,   C3 FROM   T1 WHERE   C2=:V1

Plan hash value: 236868917

-----------------------------------------------------------------------------------------
| Id  | Operation                   | Name      | Rows  | Bytes | Cost (%CPU)| Time     |
-----------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT            |           |       |       |     2 (100)|          |
|   1 |  TABLE ACCESS BY INDEX ROWID| T1        |     1 |   136 |     2   (0)| 00:00:01 |
|*  2 |   INDEX RANGE SCAN          | IND_T1_C2 |     1 |       |     1   (0)| 00:00:01 |
-----------------------------------------------------------------------------------------

Predicate Information (identified by operation id):
---------------------------------------------------
   2 - access("C2"=:V1)

SELECT
  PLAN_HASH_VALUE
FROM
  V$SQLAREA
WHERE
  SQL_ID='7p4yxrzwwuybt';

PLAN_HASH_VALUE
---------------
      236868917 

As shown above, the PLAN_HASH_VALUE for the SQL_ID found in V$SQLAREA switched back to the original value – it is again showing the PLAN_HASH_VALUE of the most recently executed child cursor.

But wait, there’s more information.  Pete Finnigan recently reminded me of a problem that I had several years ago when I tried to untangle the string of synonyms and views to see the definition of various Oracle Database performance views.  He not only reminded me of the problem that I had years ago, but showed me the process of untangling the (evoke suitable picture from above) that I learned and forgot several times over the subsequent years.

Let’s get started by determining what the V$SQLAREA synonym points at:

SET LONG 9000
COLUMN TABLE_OWNER FORMAT A11

SELECT
  TABLE_OWNER,
  TABLE_NAME
FROM
  DBA_SYNONYMS
WHERE
  SYNONYM_NAME='V$SQLAREA';

TABLE_OWNER TABLE_NAME
----------- ----------
SYS         V_$SQLAREA 

A viewed named V_$SQLAREA – now what?  Let’s see the definition of that view:

SELECT
  TEXT
FROM
  DBA_VIEWS
WHERE
  VIEW_NAME='V_$SQLAREA';

select "SQL_TEXT","SQL_FULLTEXT","SQL_ID","SHARABLE_MEM","PERSISTENT_MEM","RUNTI
...
D_TOTAL","PINNED_TOTAL","IO_CELL_UNCOMPRESSED_BYTES","IO_CELL_OFFLOAD_RETURNED_B
YTES" from v$sqlarea 

So, the synonym V$SQLAREA points to the view V_$SQLAREA which selects from V$SQLAREA … that name seems oddly familiar.

SELECT
  VIEW_DEFINITION
FROM
  V$FIXED_VIEW_DEFINITION
WHERE
  VIEW_NAME='V$SQLAREA';

select    SQL_TEXT,           SQL_FULLTEXT,           SQL_ID,           SHARABLE
_MEM,           PERSISTENT_MEM,           RUNTIME_MEM,           SORTS,
...
SICAL_WRITE_BYTES,            OPTIMIZED_PHY_READ_REQUESTS,            LOCKED_TOT
AL,             PINNED_TOTAL,            IO_CELL_UNCOMPRESSED_BYTES,
IO_CELL_OFFLOAD_RETURNED_BYTES from GV$SQLAREA where inst_id = USERENV('Instance
') 

So, the view V_$SQLAREA selects from V$SQLAREA which selects from GV$SQLAREA.

SELECT
  VIEW_DEFINITION
FROM
  V$FIXED_VIEW_DEFINITION
WHERE
  VIEW_NAME='GV$SQLAREA';

select inst_id,kglnaobj,kglfnobj,kglobt03,kglobhs0+kglobhs1+kglobhs2+kglobhs3+kg
lobhs4+kglobhs5+kglobhs6,kglobt08+kglobt11,kglobt10,kglobt01,kglobccc,kglobclc,k
...
t58,kglobt23,kglobt24,kglobt59,kglobt53 - ((kglobt55+kglobt57) - kglobt52)from
x$kglcursor_child_sqlid where kglobt02 != 0

So, the view V_$SQLAREA selects from V$SQLAREA which selects from GV$SQLAREA which selects from X$KGLCURSOR_CHILD_SQLID where KGLOBT02 != 0 (COMMAND_TYPE column in V$SQLAREA). (Note, must be logged in as the SYS user for the following SQL statement.)

SELECT
  KQFDTNAM,
  KQFDTEQU
FROM
  X$KQFDT
ORDER BY
  KQFDTNAM;

KQFDTNAM                       KQFDTEQU
----------------------------- -------------
...
X$KGLBODY                      X$KGLOB
X$KGLCLUSTER                   X$KGLOB
X$KGLCURSOR                    X$KGLOB
X$KGLCURSOR_CHILD              X$KGLOB
X$KGLCURSOR_CHILD_SQLID        X$KGLOB
X$KGLCURSOR_CHILD_SQLIDPH      X$KGLOB
X$KGLINDEX                     X$KGLOB
X$KGLTABLE                     X$KGLOB
X$KGLTRIGGER                   X$KGLOB 
...

So, in summary the synonym V$SQLAREA points to the view V_$SQLAREA which selects from V$SQLAREA which selects from GV$SQLAREA which selects from X$KGLCURSOR_CHILD_SQLID where KGLOBT02 != 0, which has as a base table of X$KGLOB just like 8 other fixed tables.  If you repeat the above steps for V$SQL, you will find that it is based on X$KGLCURSOR_CHILD, which also has X$KGLOB as its base table.

Here is a piece of SQL that joins the underlying fixed table for V$SQLAREA with V$SQL to hopefully determine if the PLAN_HASH_VALUE for the most recently executed child cursor for each SQL_ID is always what appears in V$SQLAREA (I do not suggest running this SQL statement in a production environment – the test database instance in my case was bounced a couple of hours ago).  The word DIFFERENT is output if the LAST_ACTIVE_TIME from V$SQLAREA does NOT match the LAST_ACTIVE_TIME for a specific child in V$SQL (Note, must be logged in as the SYS user for the following SQL statement.):

SELECT
  X.KGLOBT03 SQL_ID,
  X.KGLOBT30 PLAN_HASH_VALUE,
  TO_CHAR(X.KGLOBCLA,'HH24:MI:SS') LAST_ACTIVE_TIME,
  S.CHILD_NUMBER,
  S.PLAN_HASH_VALUE S_PLAN_HASH_VALUE,
  TO_CHAR(S.LAST_ACTIVE_TIME,'HH24:MI:SS') S_LAST_ACTIVE_TIME,
  DECODE(X.KGLOBCLA,S.LAST_ACTIVE_TIME,NULL,'DIFFERENT') TIMESTAMP_DIFFERS
FROM
  X$KGLCURSOR_CHILD_SQLID X,
  V$SQL S
WHERE
  X.KGLOBT02 != 0
  AND X.KGLOBT03=S.SQL_ID
ORDER BY
  S.SQL_ID,
  S.CHILD_NUMBER;
