Unable to set Local Transformers in Alfresco 7.1.0

[mohitashah1]

Greetings Everyone,

I followed this post - https://hub.alfresco.com/t5/alfresco-content-services-forum/alfresco-comunity-7-zip-haven-t-alfresco...

and installed my local Transformer Service based off Abhinav's blog - https://javaworld-abhinav.blogspot.com/2021/06/setup-acs70-ass201-and-transformation-service.html

Once, I start Alfreso and other Services like ActiveMQ, localTransformers, Alfresco and Solr6 - I see the following:

ERROR [content.transform.LocalTransform] [http-nio-8080-exec-3] Local transformer TikaAuto on http://localhost:8090/ is not available: 10106190 TikaAuto check failed to connect or to read the response

In my alfreso-global.properties file, I've set the following:

## AMQ And Transformation services
localTransform.core-aio.url=http://localhost:8090/
local.transform.service.enabled=true
messaging.broker.url=tcp://localhost:61616
messaging.subsystem.autoStart=true
#If you have setup username and password for AMQ, then set the below properties. In my case i have kept default admin/admin
messaging.broker.username=admin
messaging.broker.password=admin

How do I resolve this issue ?

Thanks and Regards,

The error indicates that the local tranform service is not running. Did you started the alfresco-transform-core-aio-boot app ? 

May be cross check whether app starts, refer this script : https://github.com/abhinavmishra14/alfresco7-solr-localtransform-dist-setup/blob/main/linux-platform...

Try accessing the url: http://localhost:8090/ in browser and see what you get after starting the service. 

You can also refer this script that starts all services: https://github.com/abhinavmishra14/alfresco7-solr-localtransform-dist-setup/blob/main/linux-platform...

Hi Abhinav,

Thank you for your response, and I'm Sorry for updating the ticket/case after so many days.

1. I added the following to the alfresco-global.properties file and the errors disappeared.

img.root=/home/alfresco/alfresco/imagemagick
img.dyn=${img.root}/lib
img.exe=${img.root}/convert
img.coders=${img.root}/modules-Q16/coders
img.config=${img.root}/config-Q16
img.url=${img.root}/url
alfresco-pdf-renderer.root=/home/alfresco/alfresco/alfresco-pdf-renderer
alfresco-pdf-renderer.exe=${alfresco-pdf-renderer.root}/alfresco-pdf-renderer

But this makes me wonder that the Legacy Transformer has kicked in and that's why the errors are not seen.

2. Secondly, I have this installed on an AWS Centos instance as suggested in your post - https://javaworld-abhinav.blogspot.com/2021/06/setup-acs70-ass201-and-transformation-service.html, So I cannot access it by using the URL - : http://localhost:8090/. So what I generally do is remote into a Windows Server in teh same AWS VPC and using the browser, I navigate to http://<ipaddress>:8090.

But when I tried the URL - http://<ipaddress>:8090, it gives me 'The page cannot be displayed', which tells me that my Local Transformer Engine is not up and running.

3. I have set it up using the localTransformationService.sh script that I call from a start.sh like this:

sudo -u alfresco $ALF_HOME/localTransformationService.sh start

4. I ran the command 'ps -eaf | grep alfresco' and realized that 'Yes, the Transformer Engine was not running. Don't know why.

5. I explicitly started it by running the ./localTransformationService.sh start and then went to http://<ipaddress>:8090 and I do see all the Transformer options.

So question to you is:

a. Can I remove the properties img.root, img.* and alfresco-pdf-renderer.* from my alfresco-global.properties file ?

b. I believe I will need to change the URL from http://localhost:8090/ to http://domainname:8090/ and also need to add the Reverse Proxy for the same.

c. Lastly, when I upgrade an Alfresco 5.x Instance to Alfresco 7.1.x Instance - I get 100s of the following Warning and Error Messages:

1 and a. -> These properties are no longer valid for ACS7.x. Legacy tr service was deprecated in acs6.x https://docs.alfresco.com/transform-service/latest/config/#transform-service-vs-local-and-legacy-tra...

2-5 and b -> You need to make sure that service starts and accessible to repository and activemq. You can also refer this script: https://github.com/abhinavmishra14/alfresco7-solr-localtransform-dist-setup/blob/main/linux-platform... which starts all required services 

c. The error should get away once 1-5 (a & b) is resolved.
