Question : Open cusor

Bonjour à tous,

J'ai récemment eu une erreur "ora-01000 maximum open cursors exceeded", comme proposé dans les actions, j'ai augmenté le nombre "open cursor" afin de ne pas être bloqué. La version d'Oracle est une Expression Edition 10g.

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

-- Depuis une session SYS SQL> show parameters open   NAME TYPE VALUE ------------------------------------ ----------- ------- open_cursors integer 300   -- Depuis l'utilisateur SQL> delete int_utilisateur where id = 43; delete int_utilisateur where id = 43 * ERROR at line 1: ORA-01000: maximum open cursors exceeded     -- Depuis une session SYS SQL> alter system set open_cursors=500 scope=both;   System altered.   SQL> show parameters open   NAME TYPE VALUE ------------------------------------ ----------- ------- open_cursors integer 500   -- Depuis l'utilisateur (nouv. session) SQL> delete int_utilisateur where id = 43;   1 row deleted.

---

Par curiosité, j'ai essayé d'identifier approximativement combien d"open cursor" était ouver part Oracle pour la suppression d'une seule ligne. J'en ai eu env. 333.

Code:

---

1 2 3 4 5 6 7 8 9

-- Requête utilisé durant la suppression pour estimer le nombre de curseurs select sum(a.value) total_cur, avg(a.value) avg_cur, max(a.value) max_cur, s.username, s.machine from v$sesstat a, v$statname b, v$session s where a.statistic# = b.statistic# and s.sid=a.sid and b.name = 'opened cursors current' group by s.username, s.machine order by 1 desc;

---

Ma suppression n'étant lié qu'à une ligne je ne m'attends pas à voir autant de curseur ouvert. Il y a bien des tables (35 en tout) lié avec la règle "DELETE ON CASCADE" et aucunes de ces tables ne contiennent de valeur pour l'ID en question.

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14

-- Requete pour identifier les tables liés SELECT 'SELECT COUNT(*) FROM ' || CONS.TABLE_NAME || ' WHERE ' || CONS_COL.COLUMN_NAME || ' = 43;' FROM USER_CONSTRAINTS CONS, USER_CONSTRAINTS PAR, USER_CONS_COLUMNS CONS_COL WHERE CONS.R_CONSTRAINT_NAME = PAR.CONSTRAINT_NAME AND CONS.CONSTRAINT_NAME = CONS_COL.CONSTRAINT_NAME AND CONS.OWNER = 'ID_FILSEK_DEMO' AND CONS.OWNER = PAR.OWNER AND CONS.OWNER = CONS_COL.OWNER AND PAR.TABLE_NAME = 'INT_UTILISATEUR' AND CONS.DELETE_RULE = 'CASCADE' ORDER BY CONS.TABLE_NAME;

---

Ma question est comment Oracle gére les curseurs? Y a-t-il des informations à ce sujet ou doit-on simplement appliquer la régle d'augmenter la limite des "open cusors"?

D'avance merci de vos réponses avisées.

Meilleures salutations,

Cédric

On delete cascade ce n’est pas vraiment recommandée.
Avez-vous vérifié la présence des triggers sur cette table et autres tables liées ? Avez-vous aussi regardé si les éventuelles autre tables liées aux tables qui sont impactées via l’option delete cascade ne sont pas eux aussi référencées par des autres clé étangère avec la clause on delete cascade ou des triggers ?
Faite une trace sql pour avoir une idée de tout ce qui se passe derrière la suppression de votre enregistrement
Plus des curseur vaut plus de mémoire pouvant être nécessaire à la session.

Je n'ai pas fait le test explicitement et effectivement je m'attends à trouver des objets qui sont eux-mêmes en "DELETE ON CASCADE". Pour ce qui est des triggers, la trace en-dessous n'en mentionne pas.

Ce qui m'intéresse est de savoir comment et quand Oracle ouvre un curseur lors d'une suppression? Est-ce qu'il ouvre un curseur pour chaque contrainte d'intégrité lié à ma table de départ => La chaîne de "DELETE ON CASCADE" peut s'avérer être un problème.

Les développeurs utilisent "DELETE ON CASCADE" afin de simplifier les traitements de suppression. Ils n'utiliseront pas, à ma connaissance, ce mécanisme si la suppression en chaîne n'est pas possible. Elle se fera manuellement et explicitement.

Quels sont les désavantages de ce mécanisme Oracle? Oracle ne fait-il pas mieux et plus rapide que du code manuel?

La suppression explicite d'un enregistrement lié entre différentes tables me paraît plus complexe à mettre en place que le mécanisme Oracle.

Pouvez-vous préciser les désavantages/avantages de votre remarque? Avez-vous un article à me conseiller?

Voici le contenu partiel de la trace :

Quels sont les désavantages de ce mécanisme Oracle?

---

La lenteur principalement.
Essayes de supprimer 100 000 enregistrements avec + de 100 tables dépendantes de celle "en haut de la pyramide" et tu comprendras ta douleur

Après il est vrai que c'est une solution de facilité car il n'y a pas grand chose à programmer ;)

La solution n'est pas nécessairement évidente mais une bonne consiste à avoir un script capable de remonter les contraintes de la BDD et faire de la purge en masse table par table et non enregistrement par enregistrement.

Je fais partie des gens qui n’aiment pas trouver 376 curseurs ouverts (regardez la synthèse du votre fichier trace) quand ils font une pauvre delete dans une table.
En gros les reproches sont
- Trop de choses qui se passent derrière la scène par automagie
- Risque augmenté de suppression des enregistrements en trop
- L’impact réel d’une requête anodine de type delete from table where cle_unique = valeur n’est pas visible au développeur/DBA/analyste
Cella ne signifie pas du tout de bannir l’ON DELETE CASCADE mais d’en user avec modération.

Merci Scriuiw pour l'explication.

J'étais un peu enfermé dans le mode de fonctionnement de nos besoins où les suppressions via l'applicatif ne sont pas faites en masse... D'où l'utilisation de ce mécanisme.

Et après réflexion et quelques recherches, nous utilisons également quelques scripts de nettoyage avec désactivation des contraintes pour gagner en rapidité. Et ce sont plus des scripts (très) occasionnels que systématique.

Je me permets de relancer ma question principale qui est de savoir quand Oracle ouvre un curseur? Ou est-ce une boîte noire et on applique "bêtement" l'augmentation systématique des "OPEN_CURSORS" lors de l'erreur?

D'avance merci,

Cédric

Oracle Concepts

Citation:

---

When an application issues a SQL statement, the application makes a parse call to the database to prepare the statement for execution. The parse call opens or creates a cursor, which is a handle for the session-specific private SQL area that holds a parsed SQL statement and other processing information.

---

En gros chaque parsing d'une requête SQL implique création ou ouverture d'un curseur.

Désolé, j'ai été pris dans d'autres problèmes.

Merci mnitu pour la réponse.

Donc quand on exécute une commande DELETE sur table qui est liée à des contraintes (DELETE ON CASCADE ou non), Oracle "engendre" autant de requêtes (donc de parsing (et donc d'ouverture de curseur) qu'il y a de liens.
Juste?

Merci à tous pour vos différentes remarques et intervention.
