Where do you set or change the host name URL?


I installed IBM TRIRIGA Application Platform 3.5.3 in Linux CentOS 7. While running the TRIRIGA installer, I selected an embedded server, that is IBM WebSphere Application Server (WAS) Liberty Profile 17.0.0.2. This server is successfully installed and up and running.

From the log, I found that the server host where IBM TRIRIGA is accessed has an URL something like this: http://some.static.ab-xyz.com:8001. This URL value was taken by default. I did not provide this value. My question is: How do I change this host name URL? Where is the setting for this?

I’m not sure what log you’re looking at and what specifically you’re seeing. What is set as your FRONT_END_SERVER value in your TRIRIGAWEB.properties file?

Why does IBM TRIRIGA 3.5.3 install give errors on WebSphere 8.5.5.11?


I am attempting a clean install of TRIRIGA 3.5.3 and according to the logs, it appears that the installation was successful within the was-ant.log. But I receive this error in the ant.log… When I access the application, I was unable to pull up the login page. Checking the server logs, I noticed these errors… The odd thing is that when I did a TRIRIGA 3.5.3 install on WebSphere Liberty, it worked perfectly…

The errors seem to indicate that you selected an upgrade, not a new install. Are you sure you selected a new install? Some of the environment properties that are needed to start up do not seem to be available. Did the database get created or are you pointing at an existing database? What happens if you do a select * from environment_properties on the database you are using?

The DB2 exception you are receiving seems to indicate you are running out of statement handles, but it’s hard to see this happen with a successful install.

What are the minimum permissions for TRIRIGA to function correctly?


In a standard OOB installation of TRIRIGA on Windows Server 2012 R2, it gives the user group the “Execute” and “Special” permissions to the TRIRIGA folder. We are concerned from a security perspective: Why are the “Execute” and “Special” permissions needed for a standard installation? What are the minimum permissions needed for TRIRIGA to function correctly?

You can remove the user group “Execute” permission on Windows. Only the service user needs permissions to read from the install directory, and/or execute WebSphere Liberty under the TRIRIGA install directory (if so installed).

Do you need to clear server cache if floor plans aren’t visible?


After performing a TRIRIGA platform upgrade, some of the floor plans are not visible in the forms. Why aren’t they visible?

The TRIRIGA server cache needs to be refreshed. In other words, you need to clear the caches and restart the server. Here are more-detailed steps to clear your TRIRIGA cache and log folder:

  1. Login to the Admin Console.
  2. Go to the “Cache Manager” managed object.
  3. Click on the “All Caches (Global)” link and then “Hierarchy Tree Data – with rebuild” link. The process might take some time.
  4. Go to the “Database Manager” managed object, and click on the “Reprocess published drawings” link. Give the process some time to finish. Go to the current server log, and look for a related entry saying that the reprocess published drawing actions are finished. You will find a message similar to the following:
    “INFO [com.tririga.platform.graphics.vector.drawing.DrawingService](http-0.0.0.0-21001-7) Finished re-processing drawings”
  5. Logout of the Admin Console.
  6. Stop the TRIRIGA JVMs via the WebSphere Admin Console.
  7. Delete the logs in the <TRIRIGA install>/log folder that has server.log.
  8. Clear the WebSphere temporary cache folder.
  9. Restart the TRIRIGA JVMs via the WebSphere Admin Console.

Why is there a JDBC exception with TRIRIGA on WebSphere and DB2?


I am getting a strange error when I am trying to deploy to TRIRIGA with the WebSphere Application Server (WAS). TRIRIGA doesn’t come up and throws an exception. Interestingly, when I point a Liberty application on the same DB2 database, it works well. I have confirmed with my network team that this is not a network connectivity issue. Here are the error logs:

Caused by: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: DB2 SQL Error: SQLCODE=-805, SQLSTATE=51002, SQLERRMC=NULLIDR1.SYSSH200 0X5359534C564C3031, DRIVER=4.18.60 DSRA0010E: SQL State = 51002, Error Code = -805...

Have you checked to see that both the Liberty server and the WAS server are actually using the exact same version of the DB2 driver (db2jcc4.jar)?

How do you fix failure to export reports to Excel due to timeout?


There are many installation scenarios that can cause TRIRIGA reports, especially BIRT reports, to fail to export due to timeout. Microsoft Excel exports are often the ones that you can observe because all of the file formatting happens during export.

Let’s focus on WebSphere Liberty installations, but this recommendation can be used for other web servers with some tweaks. Mostly, this is related to timeout settings, especially for HTTPS (SSL/TLS) connections. A good troubleshooting test is to perform the same action in a non-HTTPS (HTTP) connection. Does the report export? If so, take note of the time needed to export it and plan to extend the timeout in the HTTPS connection to at least double the time.

Refer to the IBM Knowledge Center > WebSphere Liberty > HTTP Endpoint topic. Look for the “sslOptions”, and also double-check the “httpOptions”, for timeouts.
