Bonjour ,

J' interviens chez un client sur oracle et j' ai un petit souci de temps de réponse suite à un changement de serveur de de base .
Je suis sur un serveur AIX avec un oracle 12 .

J' ai écrit une requête , le temps d 'affichage du résultat est de 4 secondes .
Je ré exécute la requête , le temps d'affichage est de 5 minutes 30 secondes .
Je re exécute à nouveau la requête , il est toujours de 5 minutes 30 secondes
Je modifie la requête , je rajoute un espace , je l' exécute , je reviens à 4 secondes.
Je re exécute la requête modifiée , je reviens à 5 min 30 secondes .

C'est une petite requête , il en existe de plus conséquentes .

Mes quelques connaissances oracle me laissait plutôt attendre un résultat inversé
Serait-ce un problème lié à la SGA , j' ai une SGA_TARGET =8G

Si quelqu'un peut m'éclairer sur cette difficulté.

Merci d 'avance

Dis comme ça, avec peu d'infos de ta part, je penserais plutôt au fait qu'il y a soit beaucoup d'activité sur ta base et que cela ralentit parfois un SELECT ou bien que ton SELECT porte sur une table dont le nombre de lignes change assez fortement à chaque lancement de ton ordre SQL.

Ce qui serait bien c'est de faire un autotrace à chaque fois.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
SQL> set autotrace on
SQL> SELECT ...

Attendre quelques secondes puis recommencer

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
SQL> SELECT ... 
...
SQL> set autotrace off

et poste nous les résultats.

Ça pourrait ressembler à un problème de cardinality feedback :

évidemment , je reproduis le cas à volonté .


Par rapport à la cardinalité , je vais analyser les plans d 'éxécution entre la première requête et la deuxième ou troisième

[pachot]

Bonjour,
La première chose à vérifier est le plan d'exécution.
Probablement auto-reoptimisation (cardinality feedback) qui essaie d'avoir de meilleures estimations mais tombe finalement sur un plan plus long. Ca peut se désactiver mais l'idéal est de comprendre pourquoi il y a des mauvaises estimations au départ.

[Ikebukuro]

Première exécution très rapide : 281857 consistent gets
Autres exécutions très lentes : 2053542 consistent gets soit près de 7 fois plus de blocs lus en mémoire...

Il nous faudrait effectivement les plans d'exécutions à chaque fois, qui sont normalement affichés avec l'autotrace.
Donne-nous aussi le texte de ta requête, à chaque fois car tu as parlé d'un espace ajouté au début de la discussion.

[j_m_j_]

bonjour ,

Ci dessous la requête et les plans d 'exécution , qui sont identiques , par contre les consistents gets sont multipliés par 10.
Quand je dis que je modifie la requête , je ne fais que rajouter un espace après un des "and" sur une des lignes que je n' ai pas encore déjà modifiée.
Précision complémentaire , il y a deux vues .

Ok. Autotrace fait un explain plan mais ce qu'il faut ici c'est voir chaque ligne du plan avec le nombre de consistent gets.
Est-ce que tu peux faire la même chose mais avec cette méthode pour avoir le plan d'exécution:
https://blog.dbi-services.com/best-p...xecution-plan/


En gros, avant la requête:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
set pagesize 10000 linesize 300 trimspool on serveroutput offalter session set statistics_level=all;

Et juste après la requête:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
spool plan.txtselect * from table(dbms_xplan.display_cursor(format=>'allstats last +advanced'));spool off

Et là on verra plus clairement quelle operation est responsable de 10x plus de consistent gets.

[j_m_j_]

la base ayant évoluée j' ai exécuté une requete légèrement différente mais le principe reste le même
une nouvelle requête rapide puis la ré execution de cette requete lente.
le plan d 'exécution est différent entre les deux requêtes pourtant je ne modifie aucunement la requête
je n' ai pas encore détaillé mais j' ai un full scan sur une table sans la deuxième requete non présent sur la première
il y a t-il une explication ?

Quand vous regardez le 1er plan vous pouvez constater que vous avez de grandes disparités entre les lignes estimées (E-rows) et les lignes réelles (A-rows)

Donc lors de la 2eme exécution vous avez un :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

- statistics feedback used for this statement

Regardez le lien que j'ai posté plus haut.

Vous avez dans le 2eme plan la ligne suivante qui est problématique :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

INDEX RANGE SCAN                | PK_BCCBC         |  76429 |      3 |   141 |     2   (0)| 00:00:01 |    131M|00:03:26.45 |    3318K|       |       |          |

Vérifier déjà le calcul des stats.

[j_m_j_]

en effectuant

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

alter session set "_OPTIMIZER_USE_FEEDBACK"=FALSE;

je n' ai plus le souci
et si

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

alter session set "_OPTIMIZER_USE_FEEDBACK"=TRUE;

le plan d 'execution choisi est le mauvais dans le cas des re execution

Si je comprends bien mes statistiques étant faussées ou sous estimés dans la première requête , il rectifie de lui même et choisit un autre plan d 'exécution .
J' ai déjà une solution , me reste plus qu' à comprendre pourquoi mes stats sont mauvaises dans la première requête


Merci à vous tous

[Ikebukuro]

ATTENTION : pourquoi parles-tu de mauvais plan d'exécution ? Dans les deux plans listés, on a le même plan hash value : 3605098231.
Donc, si ton copier/coller est correct, on n'a pas remplacé l'utilisation d'un index par un Full table scan ou l'inverse. On a le même plan d'exécution, ce qui est problématique pour expliquer le *7 du nombre de blocs lus en mémoire

Tu peux confirmer qu'on a bien le même plan d'exécution dans les deux cas : celui rapide et celui lent?

@ceux qui parlent de pb de feedback sur les stats : si c'était vrai, il n'y aurait pas une mention dans la note du plan d'exécution?

C'est bien mentionné dans le 2eme plan :
statistics feedback used for this statement

[pachot]

Oui, il faut toujours regarder les plans avec dbms_xplan.display_cursor()
Parce que autotrace fait un 'explain plan' qui n'a pas du tout le même context d'exécution.
