    ResultSet cache not refreshing upon EventDistributor.dataModification call

    Jorge Bittencourt Neto Newbie

      Hi guys,

       

      I am calling the EventDistributor.dataModification method to refresh the result set cache when data is modified but it is not reloading the cache. Even after the ed.dataModification("BankVDB", 1, "bank", tableName); is executed, the "old" value is still returned until the TTL refreshes it.

       

      Can someone, please, take a look at my configuration and try to shed some light on the issue?

       

      Here is my java method to invalidate a table cache:

      protected void invalidateCache(String tableName) {
              InitialContext ic;
              try {
                  ic = new InitialContext();
                  EventDistributor ed = ((EventDistributorFactory) ic.lookup("teiid/event-distributor-factory"))
                          .getEventDistributor();
      
      
                  ed.dataModification("BankVDB", 1, "bank", tableName);
      
      
              } catch (NamingException e) {
                  LOG.debug("Failed to lookup JDV teiid EventDistributor. Stacktrace: " + e);
              }
          }
      

       

      Here is my VDB.xml:

      <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
      <vdb name="BankVDB" version="1">
              <description>VDB</description>
              <property name="UseConnectorMetadata" value="false" />
              <model name="bank">
                      <property name="importer.useFullSchemaName" value="false"/>
                      <property name="importer.importKeys" value="true"/>
                                      <property name="importer.tableTypes" value="TABLE,VIEW"/>
                                      <property name="importer.schemaPattern" value="BANK" />
                                      <property name="importer.includeSynonyms" value="true" />
                      <source name="oracle" translator-name="oracle" connection-jndi-name="java:/Database"/>
              </model>
                      <translator name="translator-oracle" type="oracle">
                                         <property name="SupportsNativeQueries" value="true" />
                      </translator>
      </vdb>
      

       

      Here are my DataSources, both for DB and Teiid:

       <datasource jndi-name="java:/Database" pool-name="NextDS" enabled="true" statistics-enabled="true">
        <connection-url>jdbc:oracle:thin:@localhost:1521:bank</connection-url>
        <driver-class>oracle.jdbc.OracleDriver</driver-class>
        <driver>oracle.jdbc.OracleDriver_12_1</driver>
        <pool>
        <min-pool-size>5</min-pool-size>
        <max-pool-size>50</max-pool-size>
        </pool>
        <security>
        <user-name>app_user</user-name>
        <password>oracle</password>
        </security>
      </datasource>
      <datasource jndi-name="java:/teiidDS" pool-name="teiidDS" enabled="true" use-java-context="true" use-ccm="true">
        <connection-url>jdbc:teiid:BankVDB@mm://192.168.33.11:31000</connection-url>
        <driver>teiid</driver>
        <pool>
        <use-strict-min>false</use-strict-min>
        <flush-strategy>FailingConnectionOnly</flush-strategy>
        </pool>
        <security>
        <user-name>teiidUser</user-name>
        <password>Password123*</password>
        </security>
        <validation>
        <check-valid-connection-sql>select 1 from DUAL</check-valid-connection-sql>
        <validate-on-match>false</validate-on-match>
        <background-validation>true</background-validation>
        </validation>
      </datasource>
      

       

      I can't see any exceptions being logged and I am positive that the EventDistributor.dataModification method is being called. I am using JBoss EAP 6.4 and JDV 6.2.

       

      Please advise. Many thanks in advance.
