How can I take a thread dump of Xpert.ivy Server?

Reto Weiss — Tue, 03 Jun 2014 12:15:48 -0400

To analyze deadlocks in my code (and in Xpert.ivy) or endless loops it is useful to get a thread dump.

The thread dump contains information about each thread, the locks it owns, the locks it is waiting for and the whole java callstack of the thread. A thread dumps looks like this:

"http-8081-8" daemon prio=6 tid=0x000000001cd71000 nid=0x1124 in Object.wait() [0x000000001e24f000]
   java.lang.Thread.State: WAITING (on object monitor)
    at java.lang.Object.wait(Native Method)
    - waiting on <0x00000004d208fae8> (a org.apache.tomcat.util.net.JIoEndpoint$Worker)

Start a process in plain Java

Lars Tuchel — Fri, 06 Dec 2013 14:38:35 -0500

Is there a possibility to start a Xpert.ivy process from a Java bean in my ivy project? Either by calling a request start or a sub process...

Something like:

String signature = "myProcess()";
Set<IProcessStart> processes = ivy.wf.findProcessStartsBySignature(signature);
if(!processes.isEmpty()){
    IProcessStart process = processes.iterator().next();
    IProcessRequest request = RequestFactory.createProcessRequest(
        ivy.request.getProcessModelVersion(), process.getRequestPath(), 
        new HashMap<String, Object>()
    );
    try{
        // somehow send the request...
    }catch(Exception e){
        // do some exception handling if process fails...
    }
}

The main purpose is to be able to catch exceptions which may be thrown from the process.

How to migrate Active Directory connection to LDAP(S) / SSL

SupportIvyTeam — Wed, 29 Apr 2020 05:39:52 -0400

Microsoft is enforcing LDAPS for active directory services. https://www.heise.de/newsticker/meldung/Microsoft-stellt-Domaincontroller-langsam-auf-LDAPS-um-4666079.html

So we have to configure all ivyEngine user synch connections to use LDAP(S). How can this be done? Simply enabling 'SSL' option doesn't seem to be enough.

We have multiple workflow app on differen ivyEngine (4.3, 5.1, 7.0) versions in use. Is there a generic approach to use that works als in older environments?

The Q&A is dead, long live the community

Reguel Wermelinger — Fri, 21 Aug 2020 03:23:27 -0400

This Q&A served us well for many years and it contains hundreds of threads which have been read thousands of times. Thank you so much for contributing to this space! Here we all shared our knowledge and inspired others by asking questions that really matter.

However, the Q&A as a platform has grown old and hit many technical limitations. Therefore, we decided to try something new. We still believe that joint efforts lead to highly effective projects. And we also love to experiment with extended collaboration features.

As a result, we moved to a completely new space on http://community.axonivy.com . We hope to see you there soon. Right now is the perfect time to migrate: share your passion with us and, with some luck, you may win a fine local specialty from Zug.

searching in this forum

Thomas Wanka - logwin — Fri, 31 Jul 2020 04:46:51 -0400

if I search this forum using the title above I get a list of 111 questions - obviously no relation to what I was asking. Is there a way to ask more specific questions, such as "this AND that" instead of "this OR that"?

What does the function getChildRoles return? All Child rows i. e. sub-sub-sub roles of the role given, or only direct sub-roles?

Unmigrated request Start from Xpert.ivy 3.9

Thomas Wanka - logwin — Thu, 30 Jul 2020 07:25:19 -0400

Nach einer Migration von Xpert.ivy 3.9 nach Axon.ivy 7.0 steht eine Warnung auf dem "Request Start" Element, den Screenshot wollen Sie aber wegen meines schlechten Karmas nicht sehen :-(( Auf der Warnung steht sinngemäß, dass mit dem "nicht migrierten Start" die Gefahr einer unkontrollierten Übergabe von Prozessparametern besteht. Man solle für die weitere Bearbeitung in die 4.2 Designer Migration Notes schauen. Wahrscheinlich wurden diese aber mit der Version 7 nicht mehr ausgeliefert, deswegen muss ich nun hier nachfragen was konkret getan werden soll. Eigentlich soll alles so bleiben wie es migriert ist, Parameter werden nicht benötigt. Kann man das Element in einen "kontrollierten Start" umwandeln?

Email bounced Address

josef_koupal — Thu, 23 Jul 2020 08:59:39 -0400

Hallo Ivyteam

Is there a possibility to set the bounce-address used for Sending Email using the E-Mail Step (Element) ? Example: https://www.tutorialspoint.com/javamail_api/javamail_api_bounced_messages.htm

It should be sufficient to set the system property "mail.smtp.from", which i cannot find in Engine administration / System Properties.

Danke Josef Koupal

Browser back button - any workarounds ?

John Moser — Tue, 18 Feb 2020 09:23:43 -0500

Dear Ivy Team

It seems that Ivy can't handle by default the browser back button if the UI is related to a process. Your proposed solution is to suppress the back button. Imho this is not an acceptable solution especially if everything else reacts correctly to the back button.

I would assume/expect that a Ivy process which is designed with multiple "back paths" should be able to support some kind of a "back button" behavior.

Config ivy log in GCP

nndiem — Tue, 30 Jun 2020 00:38:52 -0400

Dear ivy team support,

Currently, I'm doing some configuration for the ivy log in GCP environment. Here is my config:

 <appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender">
  <param name="Threshold" value="INFO"/>
  <param name="Target" value="System.out" />
  <layout class="ch.ivyteam.log.layout.IvyLog4jLayout">
      <param name="DateFormat" value="yyyy-MM-dd HH:mm:ss.SSS"/>
    </layout>
  <filter class="org.apache.log4j.varia.LevelRangeFilter">
    <param name="LevelMin" value="INFO"/>
    <param name="LevelMax" value="WARN"/>
    <param name="AcceptOnMatch" value="true"/>
  </filter>
</appender>

<!-- appender that writes log messages with priority ERROR or higher to stderr -->
<appender name="ConsoleAppenderError" class="org.apache.log4j.ConsoleAppender">
  <param name="Threshold" value="ERROR"/>
  <param name="Target" value="System.err" />
  <layout class="ch.ivyteam.log.layout.IvyLog4jLayout">
      <param name="DateFormat" value="yyyy-MM-dd HH:mm:ss.SSS"/>
    </layout>
</appender>

  <!-- Disable CXF warning at startup (missing META-INF/cxf/cxf.xml) -->
  <category name="org.apache.cxf.bus.spring" class="ch.ivyteam.log.Logger">
    <priority value="ERROR"/>
  </category>

But I got the problem: With the exception, it will print each line of exception in the stackDriver log like this picture:

We use fluentd and Stackdriver to display the log.
As I understood, we have 2 steps to display the log in the GCP

Step 1: Base on the configuration in the log4jconfig.xml, Ivy will print the log to the console with the corresponding format so that fluentd can read it and display in the log view
Step 2: fluentd will read that log and display in the log view.

When I check step 2, it is correct because the fluentd displayed exactly the result of step 1.
But step 1 got a problem, it prints incorrectly the entry log. I have 1 block exception but it prints to multiline log entries.
My expectation: each exception case will be visualized by only 1 entry log so that developer can easier trace the exception reason and find the solution.
Could you please give me some advice?

Thank you

axis2 libraries not found in Axon.ivy 8 Engine

vinh_ — Thu, 09 Jul 2020 03:54:24 -0400

Hi Ivy Team,

I try to build Ivy 8 project with project-build-plugin-8.0.3 and Axon.ivy Engine 8.0.6 Slim All and found that I cannot build the project because org.apache.axis2.client.Options could not be resolved (some class in my project import this class).

The libraries exist on Designer under container Axon.ivy WS Call, no compile error within Designer but I could not find them on engine-path/system/plugins of the Engine.

Resources (css, js, images) in Ivy - performance impact ?

John Moser — Tue, 28 Jan 2020 04:16:07 -0500

Dear Ivy Team

Usually the static web content such as css, js, images etc are offloaded and put in a web proxy in order to reduce the data load for the app server. Of course these files must be cached on the browser side. But still they must expire on a daily basis (since hotfixes can come in on a daily basis).

Any ideas ?

Regards John

How do I add an additional Aspose module to my project and am I allowed to do so?

Switching the environment to a new physical hardware

khanh11166 — Mon, 29 Jun 2020 04:14:40 -0400

Hi Ivy team,

We are facing the challenge, that our customer will switch the PROD-Enviornment to a new physical hardware within the next few month.

We used ivy business data, task data and case data for storing the user data. We also create some folder inside the application folder and keep some pdf, image, doc file.....

The question is - How can we switch the database from the old environment to the new one? - Can we export the DB from the old ivy instance and import it to the new one? - Is there any document / guide on how to do that?

Thank you!

Unknown Java build problem in Axon.ivy Designer: Failed to init ct.sym

Elastic search End of life version, need to upgrade

khanh11166 — Wed, 24 Jun 2020 05:41:36 -0400

Hi ivy team,

Currently we are using ivy: Axon.ivy Engine 7.0.11.1903290958 In this version, we used Elastic search version 5.5.0 (default of the engine, defined here: https://developer.axonivy.com/doc/7.0/readme-engine )

But we run into the security check issue: Elastic search End of life version (check here: https://www.elastic.co/support/eol)

I want to setup an external Elastic search with the newer version to pass the security check.

So, my question is that: Which is the latest Elastic version that can be supported by Axon.ivy Engine 7.0.11.1903290958 ?

Thanks for your supporting,

Axon.ivy Engine 8 could not start on OpenShift with DeploymentConfig

vinh_ — Thu, 18 Jun 2020 21:10:54 -0400

Hi Ivy Team,

I'm trying to run Axon.ivy Engine on OpenShift, the first try with a Pod is working. Then I try to use DeploymentConfig to automate the Pod creation, it could not run because the running user didn't have permission on Axon.ivy Engine directory.

Here is the error detail:

<title>Invalid Configuration Location</title>The configuration area at '/usr/lib/axonivy-engine-8/?/.eclipse/1939981958_linux_gtk_x86_64/configuration' could not be created.  Please choose a writable location using the '-configuration' command line option.

I guest OpenShift runs Axon.ivy Engine by a different user than the one defined in Docker Image.

I think fixing the permission of /usr/lib/axonivy-engine-8 may solve the issue. By adding these line into Dockerfile

RUN chown -R ivy:root /usr/lib/axonivy-engine-8 && chmod 775 -R /usr/lib/axonivy-engine-8

Do you have any suggestion?

Update:

After fixing permission, I faced another issue, it's definitely related to OpenShift using different user.

Where does Axon.ivy Engine 8 store deployed files?

vinh_ — Fri, 19 Jun 2020 01:24:49 -0400

Hi Ivy Team,

Axon.ivy Engine 8 comes with different deployment behavior. To keep the state of Ivy Application running on Container, I need to know where does it store deployed files, to mount those paths into persistent volumes.

In other word, how many places I need to mount into persistent volumes to make Axon.ivy works on Container environment?

Configure Administrators by Environment variable in Axon.ivy 8

vinh_ — Wed, 17 Jun 2020 00:17:03 -0400

Hi Ivy Team,

I would like to configure Administrators by using Environment variable, I can configure systemdb:url by using IVY_SYSTEMDB_URL. But the structure Administrators config is different:

YAML:

Administrators:
  admin:
    Password: "${hash:mySecret}"
    Email: info@localhost.com

Can I create Environment variables like following:

IVY_ADMINISTRATORS_ADMIN=<value??>
IVY_ADMINISTRATORS_ADMIN_PASSWORD=<password>
IVY_ADMINISTRATORS_ADMIN_EMAIL=info@localhost.com

I use Environment variable because I'm running Axon.ivy Engine within Containerized environment, and Environment variable is the suitable way to store configuration.

I could see the Global Variables, Security System face the same issue.

Thank for your support.

Create Logger with Category for Runtime Log

peters — Fri, 29 May 2020 12:27:31 -0400

Hi,

I would like to create loggers, which behave like Ivy.log() i.e. which log to ivy.log and are also shown in the Designer Runtime Log) but use a custom category (instead of "user_code").

For example:

Runtime Log:

ivy.log:

Also a "dirty trick" would do, as I will encapsulate the logic at a single place.

Is it possible to create such loggers?

TIA
