Multiple DataSources in Liberty

  • 1.  Multiple DataSources in Liberty

    Posted 27 days ago

    We are currently using multiple dataSources with a JDBC-driver type4 in Liberty with CICS 5.6 and it works well. We now wanted to try the JDBC-driver type2 to compare the performance but we get an error message com.ibm.db2.jcc.t2zos.T2zosConnection.initialize: Multiple Connections are disallowed in current pre-existing attachment environment ERRORCODE=-4228, SQLSTATE=null

    All dataSource belong to the same DB2 , but have different Schemas. Does anyone use this type of configuration?
