Configuring a database query timeout
問題
If database queries are taking too long to perform, and your application is becoming unresponsive, you can configure a timeout for database queries.
原因
There is no default timeout in Confluence.
ソリューション
If you are using PostgreSQL with driver version 8.3 or later Do Not set a query timeout as described below, as it will cause a SEVERE error and prevent Confluence from starting.
You will need to reapply these changes when upgrading Confluence, as the original databaseSubsystemContext.xml file changes from version to version.
To configure a database query timeout, do the following on your test server:
- Confluence をシャットダウンします。
- Extract
databaseSubsystemContext.xmlfrom theconfluence-x.x.x.jarthat is inconfluence/WEB-INF/lib/, and put a copy inconfluence/WEB-INF/classes/. See Editing files within .jar archives. Edit
confluence/WEB-INF/classes/databaseSubsystemContext.xmlto add the defaultTimeout property to the "transactionManager" bean:<bean id="transactionManager" class="org.springframework.orm.hibernate.HibernateTransactionManager"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> <property name="defaultTimeout" value="120"/> </bean>タイムアウトは秒単位で測定され、この時間を超過するクエリは強制的に中止されます。場合によっては、これらのエラーが Confluence によりうまく処理されず、Confluence エラーページが表示されることがあります。
- Confluence を起動します。
Once the timeout is working properly in your test environment, migrate the configuration change to your production Confluence environment.
