    CUSTOMER SUCCESS STORY

    A Multinational Financial Services Corporation was seeing an issue while executing queries. The customer was injecting a query hint into a view to override the server level configurations for Cases sensitivity and Trailing spaces.

    The hint worked fine in the view, but it was not getting forwarded to its child view. The customer was previously on TIBCO Data Virtualization 7.0.2 and saw no issues forwarding a hint to child view. However after upgrading to TIBCO Data Virtualization 7.0.5, the customer observed the difference in the behavior of the hint in child views.

    We checked internally and found that this change occurred in TIBCO Data Virtualization 7.0.4 and was intentional. But this customer was happy with the previous behavior and wanted to retain it. To achieve original behavior, it would have required a lot of code refactoring. Our product management and engineering team had a foresight of the customer's expectations. Therefore, they added a configuration to revert back to the original behavior, with a simple one click.

    The original behavior can be retained using the option below:

    Studio > Administration > Configuration > Server > SQL Engine > Overrides > Enable Old Select Option Compatibility Mode > change to true

    The customer was able to resume their project and use the views with expected behavior.

    This is an example of how we make an attempt to keep "customer first" in our mind, before making any changes that may possibly impact them.

    Helpful Tips:
    1. Steps to upgrade JRE in the TIBCO Data Virtualization instance

      Method A:
      1. Shutdown TIBCO Data Virtualization server, Repository, Monitor

      2. Check for any Java processes and kill them if there are any

      3. Rename the original JRE directory $COMPOSITE_HOME/jre to jre_1.6

      4. Rename the updated(new) JRE directory to jre. 

      5. CIS will now use the new JRE with original directory name.

      Method B: 
      1. Shut down the TIBCO Data Virtualization server

      2. Edit composite_server.sh and composite.sh to change JAVA_HOME to point to the location of the new JRE

      3. set JAVA_HOME= <TIBCO Data Virtualization install dir>\jre

      4. Edit <TDV_install_dir>/conf/server/server_values.xml to change the JRE path to the new location

         <common:attribute>      <common:name>/server/config/files/jreDirectory</common:name>      <common:type>STRING</common:type>      <common:value><-----new path to JRE----></common:value>  </common:attribute>

      5. Restart the TIBCO Data Virtualization server

      6. Verify that the TIBCO Data Virtualization process is using the new JRE

      Eg.,  $ps -elf | grep -i ServerBoot | awk '{print $15}'

      /opt/Composite_Software/CIS_5.1.0/jre/bin/java

    2. Kerberos Configuration for HIVE datasource 

      How to configure Vertica SQL on Hadoop as a Data Source and Kerberos Authentication?

      In the advanced Tab of the HIVE datsource - Add Kerberos SPN and Auth Type for the Connection URL Pattern.
