    When a connection to a data source fails to close due to an error, that connection is no longer reused. Prior to this fix, the data source connection wouldn't be removed immediately, which could result in an error during a subsequent data source interaction. When the error occurred, an error message with the text "Connection is closed" would be logged.

Perform the following steps to apply the hotfix:

  1. Stop Appian. See Starting and Stopping Appian for detailed instructions:
    1. Shut down the application server.
    2. Shut down the search server.
    3. Shutdown all Appian Engines, ensuring that the engines are checkpointed upon shutdown.
  2. Back up your existing Appian instance. See Backing Up Your Existing Appian Instance for instructions.
  3. Unzip the contents of the archive into your <APPIAN_HOME> directory.
  4. Run the deleteFiles script (deleteFiles.bat on Windows, on Linux) that is now located in your <APPIAN_HOME> directory.
  5. Unzip the contents of the archive that is now located your <APPIAN_HOME> directory.
  6. If you maintain customized or overridden Spring Security .xml files, merge them with the associated base files in the /deployment/web.war/WEB-INF/conf/security/ directory.
  7. Delete the deleteFiles script and
  8. If you are using a Web server, copy the content of <APPIAN_HOME>/ear/suite.ear/web.war to the folder where the Web server is getting the static resources. See Copy Static Resources to the Web Server for more information.
  9. Clear the application server cache
    • If you are running JBoss, delete the folder <JBOSS_HOME>/standalone/tmp/work/jboss.web/default-host/suite (including all subfolders) to clear the application server's JSP cache
    • If you are running WebLogic, delete the <WEBLOGIC_HOME>/<project_name>/domains/<domain_name>/config/deployments/<suite.ear> and ` //domains//servers/AdminServer/tmp/_WL_user/` directories to clear the cache when re-deploying the application.
  10. If you are using WebLogic:
    • Delete the existing suite.ear from WebLogic.
    • Deploy the Appian EAR.
      • From the WebLogic Administration Console, on the Deployments screen, click Install.
      • Select suite.ear (<APPIAN_HOME>/ear/suite.ear) and click Next.
      • Select Install this deployment as an application and click Next.
      • On the next screen, click Finish.
  11. Start Appian:
    1. Start the Appian Engines.
    2. Start the search server.
    3. Start the application server.

To determine if Appian 17.4 Hotfix Package R is deployed, open the file located in <APPIAN_HOME>/ear/suite.ear/conf. The contents of this file should match the following code sample:

##Appian Corporation Build Information
