Question

我正在使用以下配置以持久模式启动ignite db-

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">
    <!--
        Alter configuration below as needed.
    -->
    <bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
     <!-- Enabling Apache Ignite Persistent Store. -->
        <property name="dataStorageConfiguration">
            <bean class="org.apache.ignite.configuration.DataStorageConfiguration">
                <property name="defaultDataRegionConfiguration">
                    <bean class="org.apache.ignite.configuration.DataRegionConfiguration">
                        <property name="persistenceEnabled" value="true"/>
                    </bean>
                </property>
            </bean>
        </property>
    </bean>
</beans>

此配置位于config/default-config.xml文件中

之后，我使用-

启动sqlline控制台。

sqlline.sh --color = true --verbose = true -u jdbc：ignite：thin：//127.0.0.1/

在控制台中，当我执行任何DDL查询时，会出现以下错误-

java.sql.SQLException: Can not perform the operation because the cluster is inactive. Note, that the cluster is considered inactive by default if Ignite Persistent Store is used to let all the nodes join the cluster. To activate the cluster call Ignite.active(true).

    at sqlline.SqlLine.start(SqlLine.java:373)
    at sqlline.SqlLine.main(SqlLine.java:265)

我应该如何激活集群？我在哪里叫Ignite.active（true）？

注意：我正在ubuntu 18.0.4中使用Gridgrain ignite社区版8.7.5

最简单的方法是使用control.sh脚本，您可以在bin目录中找到该脚本：

control.sh --activate

其他方式are documented。

以持久性存储模式启动ignite并使用sqlline控制台进行查询
