Question

我正在使用wso2esb4.8.0和wso2dss3.0.1。我的问题是我希望将数据插入到2个表中，它的工作正常但是我希望为我的表applay事务，这两个表存在于同一个DB中。如果我的第二个表继续在我的第一个表应该回滚的任何时刻失败为此，我的DSS数据源配置为 enter image description here

我的数据服务是这样的，我启用了boxcar for transaction

<data disableStreaming="true" enableBoxcarring="true" name="Transaction" serviceNamespace="http://ws.wso2.org/dataservice">
   <config id="default">
      <property name="carbon_datasource_name">USCProduction</property>
   </config>
   <query id="insertinto_mclient" useConfig="default">
      <sql>insert into mclient(clientcode,clientname,createdbyid,modifiedbyid) values(?,?,?,?)</sql>
      <param name="clientcode" ordinal="1" sqlType="STRING"/>
      <param name="clientname" ordinal="2" sqlType="STRING"/>
      <param name="createdbyid" ordinal="3" sqlType="BIGINT"/>
      <param name="modifiedbyid" ordinal="4" sqlType="BIGINT"/>
   </query>
   <query id="insertinto_mcompany" useConfig="default">
      <sql>insert into mcompany(companycode,companyname,createdbyid,modifiedbyid,clientid) values(?,?,?,?,?)</sql>
      <param name="companycode" ordinal="1" sqlType="STRING"/>
      <param name="comapnyname" ordinal="2" sqlType="STRING"/>
      <param name="createdbyid" ordinal="3" sqlType="BIGINT"/>
      <param name="modifiedbyid" ordinal="4" sqlType="BIGINT"/>
      <param name="clientid" ordinal="5" sqlType="BIGINT"/>
   </query>
   <operation disableStreaming="true" name="insertinto_mclient_OP" returnRequestStatus="true">
      <call-query href="insertinto_mclient">
         <with-param name="clientcode" query-param="clientcode"/>
         <with-param name="clientname" query-param="clientname"/>
         <with-param name="createdbyid" query-param="createdbyid"/>
         <with-param name="modifiedbyid" query-param="modifiedbyid"/>
      </call-query>
   </operation>
   <operation disableStreaming="true" name="insertinto_mcompany_OP" returnRequestStatus="true">
      <call-query href="insertinto_mcompany">
         <with-param name="companycode" query-param="companycode"/>
         <with-param name="comapnyname" query-param="comapnyname"/>

         <with-param name="clientid" query-param="clientid"/>
      </call-query>
   </operation>
</data>

我想插入我的数据，因为我的代理配置如下

我通过CURL命令

发送数据

curl -v -H "Accept: application/xml" -H "Content-Type:application/xml"  -d '<a><clientcode>ff</clientcode><clientname>ffff</clientname><companycode>dd</companycode><companyname>mm</companyname></a>' http://youtility2-desktop:8290/services/TransactionProxy

插入工作正常，但如果我在第二个表中创建错误，即使第一个表数据插入其中并不担心第二个表，回滚也无法正常工作。如果我删除了OUT_ONLY属性，则会出现错误我跟踪此博客enter link description here

Answer 1

假设你正在使用postgres，你可以检查一下你是否在“/etc/postgres/postgres.conf”中将“max_prepared_transactions”设置为非零值。此外，在这种情况下你需要OUT_ONLY属性，因为你正在进行插入和你不期待任何回复。“你需要在一条消息上将此属性设置为'true'，以指示从ESB转发后不会有响应消息。”

事务回滚在wso2esb4.8.0中不起作用
