WSO2 CEP使用Teradata數據庫連接的事件表拋出空異常

我嘗試在Siddhi引擎中使用事件表，並通過JDBC Teradata驅動程序連接到Teradata數據庫。WSO2 CEP使用Teradata數據庫連接的事件表拋出空異常

Teradata Database作爲安裝了WSO2CEP的計算機上的虛擬機運行。所有我已經把Teradata的JDBC驅動程序terajdbc4.jar在

<WSO2CEP_HOME>/repository/components/lib/

目錄，和驅動程序的附加部分的

首先tdgssconfig.jar投入

<WSO2CEP_HOME>/bin

目錄。然後我重新啓動服務器CEP並提出旁邊的參數在「數據源」連接：

Datasource type: RDBMS 
Name: Teradata 
Datasource provider: default 
Driver: com.teradata.jdbc.TeraDriver 
URL: jdbc:teradata://192.168.96.128/LOG=DEBUG 
User name: xxxxx 
Password: xxxxx

測試連接工作正常。

我已經創建了一個新的執行計劃，它將輸入數據流與Teradata數據庫結合在一起。

@Export('pcrf_out:1.0.0') 
define stream pcrf_out (meta_event string, meta_user_id int, value int); 

@Import('pcrf_in_filtered:1.0.0') 
define stream pcrf_in_filtered (meta_event string, meta_user_id int, value int); 

@From(eventtable='rdbms', datasource.name='Teradata', table.name='user_profile') 
define table user_profile (user_id int, usual_traf_usg int); 

/* JOIN WITH RELATIONAL TABLE */ 

from pcrf_in_filtered as a join user_profile as b 
    on a.meta_user_id == b.user_id and b.usual_traf_usg==100 
select a.meta_event as meta_event, a.meta_user_id as meta_user_id, a.value as value 
<i>insert into pcrf_out;

當我運行腳本的驗證，然後我看到一個錯誤信息：空

Audit.log包含一條消息：

同執行計劃適用於Mysql連接。

有人可以幫我嗎？ 謝謝！

基於以上堆棧跟蹤類似的異常時，有沒有在查詢中指定任何此類數據源服務器只能發生（See）

你確定你在下面的查詢指定定義數據源（相同的名稱，情況下，也相同）..

@From（事件表= 'RDBMS'，datasource.name = '的Teradata'，table.name = 'user_profile'）

回答爲下query-- ------

爲了使它工作，我們必須爲新的數據庫類型定義db映射（默認情況下，它具有h2，mysql，mssql和oracle的映射）。然後請在db映射文件中添加以下條目。您可以在siddhi-extension-event-table_3.0.5.jar（位於/ repository/components/plugins文件夾中）中找到名爲rdbms-table-config.xml的文件。請在下面添加屬性在該文件中，並更新JAR文件..在這裏，你需要將數據庫元名稱添加爲映射名稱。請參見here ..

<mapping db='teradata'> 
    <elements/> 
</mapping>

嗨Mohanadarshan！你是對的！我的連接名爲'teradata'。當我修復它時，我得到了一個新的錯誤（我已經打開了跟蹤）。請在這裏查看完整的錯誤堆棧：[link]（https://www.dropbox.com/s/fzczbicwkh6wka1/wso2cep_jdbc_err?dl=0） –
