SAP XI/PI JDBC Receiver communication channel

Question

Dear Expert,
    We had few DAE running in company, recently I had below problem, need expert to advise how to overcome this problem.
   Try to execute below JDBC statement in our few AE and DAE,
=============================================================================================
<?xml version="1.0" encoding="UTF-8" ?>
<ns0:MT_OSPEN_TEST_DATA_JDBC2JDBC_COMMIT_T1 xmlns:ns0="http://testing/pen/test/jdbc2jdbc_commit">
<STATEMENT_UPDATE_INSERT_MYTESTTABLE>
<dbTableName action="UPDATE_INSERT">
  <TABLE>TMDB_DATA.MYTESTTABLE</TABLE>
<access>
  <COLUMN_VARCHAR1>Constant001</COLUMN_VARCHAR1>
  <COLUMN_VARCHAR2>Constant002</COLUMN_VARCHAR2>
  <COLUMN_FLAG>Y</COLUMN_FLAG>
  </access>
<key>
  <COLUMN_VARCHAR1>Constant001</COLUMN_VARCHAR1>
  </key>
  </dbTableName>
  </STATEMENT_UPDATE_INSERT_MYTESTTABLE>
<STATEMENT_COMMIT>
<dbTableName action="SQL_DML">
  <access>COMMIT</access>
  </dbTableName>
  </STATEMENT_COMMIT>
  </ns0:MT_OSPEN_TEST_DATA_JDBC2JDBC_COMMIT_T1>
=============================================================================================
DAE with MSSQL DB, can execute above statement successfully but
DAE wit Oracle DB had below error:
My question is, why DAE with MSSQL DB can execute the above statement without any error and DAE with ORACLE DB cannot execute the above statement correctly ? How to overcome this problem if I need to execute this statement in DAE ORACLE  ?

Answer 1

Hi,
For XI,RFC and Idoc when it's pointing to one SAP system you don't need any further comm channels.
For JDBC , if you are pointing to only one database you can use the same channel, if the target/databse changes you need more comm channels.
Your Design is as per the standards.
