Compare two instances

[ps43207436]

Hello,

I have two instances of AEM 6.1 and on publishing one of the specific documents from two of the servers, outputs are different. One of the PDF is correct where images are at correct locations, however from other instance PDF is not generating correctly (Images are losing placement).

Is there anything in AEm which can use for comparing the instances causing this.

Do you see any error on the instance with the distorted result?

Can you help us reproduce this?

ACS Commons have "JCR Compare":-JCR Compare

//

Quickly compares the contents of AEM instances. JCR Compare computes checksums for specified node types (via an aggregated checksum of that node’s descendants) across multiple AEM instances and then compares the checksum results to identify what node (and node sub-systems) are the same or different.

This is a useful tool for checking for content inconsistencies across AEM instances that would be otherwise difficult to find.

be aware: comparing a lot of content can take a lot of time.

Hello Kutuk,

Thanks for the information.

There were no error reported in logs on creating the PDF.

As Jorg mentioned, it may take time, I will avoid that.

Is there any verbose which can enable to capture detailed log and errors? AND is there something like preferences or system info something else which can quickly provide the information.

Thanks Jorg.

You can also login into 2 publisher instances and inspect asset in both instances.  Besides, you can generate 2 packages from each publish instance to analyze and compare both packages in order to identify something wrong with structure, asset or anything else that appear in the comparison.

Thanks Diego,

Could you please explain "you can generate 2 packages from each publish instance to analyze and compare both packages in order to identify something wrong with structure"?

Basically, you  have to :

In case you have admin/crx access or you should request to DevOps/infra or appropriated team the following steps:

1. connect each publishers (by ip:host or hostname)
2. go to package manager (e.g: http://localhost:4503/crx/packmgr/)
3. login in (admin/admin or use the credential associated)
4. create a package configuring the filter with target pdf path.
5. download the zip file generated for each instance
6. unzip in your filesystem both packages (pdf from instance 1 and 2)
7. compare both folders with any compare tools(win merge, diff command or whatever) to identify any weird thing in the pdf structure.

Best
