Dans un environnement de production il est indispensable de mettre en place une politique de purge des instances SOA. Afin de ne pas se retrouver avec une base de données qui grossie continuellement. Contrairement à l’Oracle SOA Suite 12c, la purge des instances n’est malheureusement pas gérée en automatique dans la 11g. Cependant, Oracle met à disposition des scripts standards pour la purge.
Procédure de purge
Les scriptes de purge d’Oracle se trouvent dans :
{MW_HOME}/rcuHome/rcu/integration/soainfra/sql/soa_purge/soa
Dans cet article nous allons utiliser la procédure « delete_instance ».
Il faut noter que les instances avec l’état « Completed successfully », « Faulted », « Terminated by user », « Stale » et « Unknown » peuvent être purgées par la procédure. Par contre, les instances qui sont à l’état « Recoverable » et « Running » ne peuvent pas être purgées.
- Description des paramètres de la procédure « delete_instance » :
| min_creation_date | Date début, de création des instances. |
| max_creation_date | Date fin, de création des instances. |
| batch_size | La taille du Batch. Par défaut 20000. |
| max_runtime | Temps d’exécution maximale. Par défaut 60 min. |
| retention_period | Période de rétention. |
| composite_name | Le nom du composant à purger. |
| composite_revision | La version du composite à purger. |
| soa_partition_name | La partition à laquelle le composite appartient. |
- Exemple d’utilisation de la procédure « delete_instance » (Vous pouvez l’exécuter dans SqlDeveloper) :
DECLARE
MIN_CREATION_DATE TIMESTAMP;
MAX_CREATION_DATE TIMESTAMP;
BATCH_SIZE NUMBER;
MAX_RUNTIME NUMBER;
RETENTION_PERIOD TIMESTAMP;
PURGE_PARTITIONED_COMPONENT BOOLEAN;
COMPOSITE_NAME VARCHAR2(200);
COMPOSITE_REVISION VARCHAR2(200);
SOA_PARTITION_NAME VARCHAR2(200);
IGNORE_STATE BOOLEAN;
BEGIN
MIN_CREATION_DATE := '01-03-2015 00:00:00';
MAX_CREATION_DATE := '30-03-2015 00:00:00';
BATCH_SIZE := 20000;
MAX_RUNTIME := 60;
RETENTION_PERIOD := '30-03-2015 00:00:00';
PURGE_PARTITIONED_COMPONENT := false;
COMPOSITE_NAME := 'MonComposite';
COMPOSITE_REVISION := '1.0';
SOA_PARTITION_NAME := NULL;
IGNORE_STATE := false;
SOA.DELETE_INSTANCES(
MIN_CREATION_DATE => MIN_CREATION_DATE,
MAX_CREATION_DATE => MAX_CREATION_DATE,
BATCH_SIZE => BATCH_SIZE,
MAX_RUNTIME => MAX_RUNTIME,
RETENTION_PERIOD => RETENTION_PERIOD,
PURGE_PARTITIONED_COMPONENT => PURGE_PARTITIONED_COMPONENT,
COMPOSITE_NAME => COMPOSITE_NAME,
COMPOSITE_REVISION => COMPOSITE_REVISION,
SOA_PARTITION_NAME => SOA_PARTITION_NAME,
IGNORE_STATE => IGNORE_STATE
);
END;
La procédure purge toutes les instances qui répondent aux critères suivent :
- Composite “MonComposite”
- Version 1.0
- Partition “default”
- Créées entre : le 01-03-2015 00:00:00 et 30-03-2015 00:00:00
- Période de rétention : Instances modifié avant le 30-03-2015 00:00:00
Il n’est pas suffisant d’exécuter le dernier script. Il doit être accompagné du script ci-dessous, qui permettra de récupérer l’espace disque alloués aux objets de la base de données.
