Question

我已经安装了wso2esb-4.9.0，主数据源配置为oracle DB。当由于网络连接问题而导致与Oracle数据库的连接断开时，即使连接再次返回，也会不断打印以下错误。只有在重新启动后，异常才会停止。

Answer 1

在我的情况下，问题是由文件存储库/ config / registry.xml中删除的错误行引起的。

我已删除此代码：

<dbConfig name="wso2registry">
    <dataSource>jdbc/WSO2CarbonDB</dataSource>
</dbConfig>

而不是添加另一个dbConfig标记。

对我来说，修正是重新添加标签。像这样：

<wso2registry>

<!-- These are used to define the DB configuration and the basic parameters to be used for the registry -->

<currentDBConfig>wso2registry</currentDBConfig>
<readOnly>false</readOnly>
<enableCache>true</enableCache>
<registryRoot>/</registryRoot>

<!-- This defines the default database and its configuration of the registry -->

<dbConfig name="wso2registry">
    <dataSource>jdbc/WSO2CarbonDB</dataSource>
</dbConfig>

<dbConfig name="sharedregistry">
    <dataSource>jdbc/WSO2RegistryDB</dataSource>
</dbConfig>
...
...
</wso2registry>

我遇到了同样的问题。

在master-datasources.xml中 1-设置与jndiConfig名称相同的数据源名称 2-设置2个不同的数据源，具有不同的名称，用于注册表和用户管理。这是我的master-datasources.xml

<datasource>
        <name>WSO2REG_DB</name>
        <description>The datasource used for registry</description>
        <jndiConfig>
            <name>jdbc/WSO2REG_DB</name>
        </jndiConfig>
        <definition type="RDBMS">
            <configuration>
                <url>jdbc:mysql://localhost:3306/registry?autoReconnect=true&amp;relaxAutoCommit=true&amp;</url>
                <username>apiuser</username>
                <password>apimanager</password>
                <driverClassName>com.mysql.jdbc.Driver</driverClassName>
                <maxActive>50</maxActive>
                <maxWait>60000</maxWait>
                <testOnBorrow>true</testOnBorrow>
                <validationQuery>SELECT 1</validationQuery>
                <validationInterval>30000</validationInterval>
            </configuration>
        </definition>
    </datasource>

    <datasource>
        <name>WSO2UM_DB</name>
        <description>The datasource used for user management</description>
        <jndiConfig>
            <name>jdbc/WSO2UM_DB</name>
        </jndiConfig>
        <definition type="RDBMS">
            <configuration>
                <url>jdbc:mysql://localhost:3306/userstore?autoReconnect=true&amp;relaxAutoCommit=true&amp;
                </url>
                <username>apiuser</username>
                <password>apimanager</password>
                <driverClassName>com.mysql.jdbc.Driver</driverClassName>
                <maxActive>50</maxActive>
                <maxWait>60000</maxWait>
                <testOnBorrow>true</testOnBorrow>
                <validationQuery>SELECT 1</validationQuery>
                <validationInterval>30000</validationInterval>
            </configuration>
        </definition>
    </datasource>

在registry.xml中 1-使用用户管理数据源设置wso2registry dbConfig 2-设置govregistry dbConfig和注册表数据源

这是我的registry.xml

<dbConfig name="wso2registry">
    <dataSource>jdbc/WSO2UM_DB</dataSource>
</dbConfig>

<dbConfig name="govregistry">
    <dataSource>jdbc/WSO2REG_DB</dataSource>
</dbConfig>

它对我有用，我的IS-Server可以正常启动。当问题尚未解决时，希望它也适合你。
