Thin jdbc ドライバーを使用して Spring で Oracle ネイティブ接続プールを使用していて、以下のエラーに気付いています。

Spring構成ファイルでデータソースを構成する方法は次のとおりです

<bean id="datasourceone" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close">
    <property name="connectionCachingEnabled" value="true" />
    <property name="URL">
        <value>jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)(ADDRESS=(PROTOCOL=TCP)(HOST=xyz-01) (PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=xyz-02) (PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ABCD)))</value>
    </property>
    <property name="user">
        <value>XYZ</value>
    </property>
    <property name="password">
        <value>XXXX</value>
    </property>
    <property name="connectionCacheProperties">
        <value>
            MinLimit:1
            MaxLimit:5
            InitialLimit:1
            ConnectionWaitTimeout:120
            InactivityTimeout:180
            ValidateConnection:true
        </value>
    </property>
</bean>

誰かが同じことについて何か推奨事項を提供できる場合、強くお勧めしますか? 接続プールのチューニングは役に立ちますか? はいの場合、調整する必要がある具体的なものはありますか?

これを接続文字列として試してください：

jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xyz-01)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=xyz-02)(PORT=1521))(LOAD_BALANCE=on))(CONNECT_DATA=(SERVICE_NAME=ABCD)))

もう一度テストします。
