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.

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!

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,

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?

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.

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.

Can't add Applications from Admin Settings

xchatter — Tue, 25 Feb 2020 02:15:21 -0500

Hi everyone,

We have currently the following problem: -> From the Cockpit we add and deploy our applications and everything is fine, however afterwards when we login to the portal home and go to Admin Settings from the user menu in order to add the new application, we get empty list when hitting Select.

The same happens when we test from the developer studio. Furthermore the users can't choose languages I guess because we can't add the application.

I tested the same thing with just some test project on 8.0.0(from the designer only) and everything works:

Any help is appreciated! :)

Printers not found when deployed

Marco Klauenbösch — Thu, 13 Feb 2020 04:00:33 -0500

When searching for printers with PrinterJob.lookupPrintServices(); everthing works fine locally in the Designer. After deploying the application, it only finds "Microsoft XPS Document Writer". I was thinking maybe the printers aren't installed on the server, but they are. When installing the Designer on the Server, everything works fine too.

I couldn't really find any helpful information about this exact problem/behavior. I've tried to change the Ivy Engine Service user from the local user to the one I used to login to the server, but that didnt help either.

Ivy Engine 8 Deployment API

Deployment of iar is very slow

khanh11166 — Thu, 07 Nov 2019 22:23:22 -0500

Hi support team,

Currently we faced with the problem of deployment process. Whenever we deploy a .iar file to the engine (via adminUi, or ivy_deployment_tool), it will cost us a lot of time (about 5-10 minutes).

But after we restart, the first time deployment is much much faster (take around 1 minutes).

Is there any hint for me to improve the deployment without restart engine?

Thank you!

Admin Ui is not launching

a_v_a — Mon, 16 Sep 2019 10:00:41 -0400

Hello everyone,

If we have set proxy name and port in the engine then we are not able to launch the Admin UI tool.

The error is:

How could we overcome this issue, having the proxy settings set and the being able to use the tool?

Thank you for your input in advance :)

Reload Process Model programmatically?

vinh_ — Tue, 09 Jul 2019 10:32:06 -0400

Hi IvyTeam,

I sometime manually replace the deployed classes by the new one. Is there anyway to tell Ivy Engine reload the Process Model contains these classes? Just like when we deploy new Process Model Version.

FYI: I'm using Ivy Engine for my local development, everytime I build the modules, I need to copy the iar to deploy folder (or use Admin Tool to deploy), It's really take time, I want to automate it.

Docker, Global Properties, Placeholder, app.yaml

John Moser — Mon, 20 May 2019 11:20:27 -0400

Hi Ivy Team

Assuming I have a global prop such as :

myGlobalProp: http://myIP:1234/whatever

myIP is different for Dev, Test and Prod. Is there a way to "inject" myIP at startup of the Docker image ?

Or generally:

If I want to build an image which should be deployed in Dev, Test and Prod, is there a way to parameterize all the config files used for the Ivy Engine (yaml, xml, etc.) ?

Thanks & Regards John

Ports opened by the Engine

Stelt0 — Fri, 29 Mar 2019 02:59:06 -0400

Hello Ivy Team,

Do we have somewhere a list of all ports that Axon.Ivy Engine is opening ? I know only for the HTTP(s) and AJP ports. Do we have others that are opening behind the scenes ?

We found a port conflict with another application on port 9999 on one of our instances. I was not aware that this port was used by the Engine and I don`t know where to configure it.

I found only this occurrence in the settings:

How can we configure this one to listen on another port ?

Best Regards, Yordan

VisualVM doesn't show SOAP Webservices and External Databases

Lukas Lieb — Mon, 05 Nov 2018 06:10:15 -0500

On my machine I have VisualVM with the Axon.ivy Plugin installed and running. Now I start an Engine and deploy an App with some SOAP Webservices. If I start a process witch trigger one of these webservices, nothing shows up in my VisualVM SOAP Web Services tab. The same issue is appearing in the External Databases Charts tab.

Use Axon.ivy Engine libraries in a plain Java process (Not Supported)

AxonIvyDeveloper — Wed, 17 Oct 2018 03:05:27 -0400

Hi everybody,

In my project in designer 7.0.8 I've Axon.ivy Libraries who are available.

Like commons-io-2.5.jar from apache.

I'm using a class from this jar, in designer it works fine.

But when I'm starting my project into the engine I get a classpath exception.

I searched into the Engine documentation and plugins / lib - this jar is not present.

How can I solve this problem? and why are not all the Axon.ivy libraries who are in Designer in the classpath not present in the Engine? What should we do, manually copy all the jars into the engine and add them into the classpath or as a plugins? in version 6 there were available.

It's weird because now we have Axon.ivy Libraries (who are provided in all projects) and optional classpaths to add like Axis or Drools libraries. All the libraries contained into the optional classpaths are present in the Engine plugins directory. But the Axon.ivy Libraries who are automatically available in the Designer without adding extra classpath containers are not all available... It sounds so weird to me...

Thanks for the information and cheers, Axon Ivy Developer

How to change the log level without restarting the engine

Is there any way (including DB manipulation) to delete unused (because for example renamed) variables and/or web services in the Engine?

Axon Ivy engine AJP port (8009) is not listening

nguyen_to — Thu, 03 May 2018 03:11:34 -0400

Hi all, I download axon ivy engine (version 7.1.0) and start the engine in demo mode. I also check the web server config and see that AJP port is enabled:

But I check windows port and see no 8009 port listening. Do I need anymore config step to open the port?

Engine installation on Linux

imoteb — Wed, 21 Mar 2018 04:23:31 -0400

Hello everyone, when I try to run the command ./AxonIvyEngine i got the following error:

Cannot start the engine with user 'root'. Please run it with a normal user such as 'ivy'.

How can I fix this issue, is it necessary to create separate user to do it.

Multiple ElasticSearch on same machine (multiple ivy engines)

trungdv — Fri, 09 Mar 2018 01:48:49 -0500

Hi ivyteam

My team has a server which has 3 instances of Ivy engine on it. Sometime when we restart engine, it cause issue that "ES can not be started. Connection refused"

As far as i know on each engine it sill contain one ES and it will be started when engine is started. By default, ES will take port 9200 or 19200 on localhost (Reference link https://developer.axonivy.com/doc/latest/EngineGuideHtml/installation.html#installation.elasticsearch )

So is there any cases that the port is conflicted in my situation? If so, how can we configure the port for many instance of Ivy engine? We're using Amazon cloud so it's not a good way to buy different server for each Engine on cloud.

Thanks

Engine mimimum system requirements

Hello, Ivy Team,

I was trying to find in the documentation what are the minimum system requirements for axon.ivy 7.0 engine (CPU, RAM, HDD). My goal is to have simple demo environment.

Let say, I want to install it somewhere on Amazon on VM with 1 CPU hosting on windows 2012 with MySql. Would be possible to run with 512 RAM or am I to optimistic ? :)

Best Regards, Yordan

Migration Ivy Server to another Machine

Stelt0 — Tue, 21 Nov 2017 08:29:28 -0500

Hello, Ivy Team,

We are planning to move one existing installation of Axon.Ivy Server to another machine. What are the pitfalls in such scenarios?

We will copy-paste the whole installation folder to the new server (the file system paths will be the same)
We will attach the AxonIvySystemDatabse to the new server (p.s. we will also migrating to different db server)
We need to change the license file
We need to update the configuration to point to the new db server
Probably we need to update the server name in the Admin UI

All should be straightforward, right ? Are we missing something ?

Best Regards, Yordan
