<br>
to enable us to help you, you have to explain in more detail what <br>
exactly you have implemented and what exactly the problem is. There is <br>
no default feature to do OCR with Alfresco.<br>
<br>
Independant from your specific implementation I always recommend not to <br>
even save a document in Alfresco if this is to be used for OCR. Instead <br>
do your OCR processing _before_ you save that doc in Alfresco.<br>
<br>
This recommendation has several reasons:<br>
* Alfresco's transformation engine has no concept to replace a node <br>
which is expected in most OCR scenarios.<br>
* as long you don't use the EE Transform Service any transformation will <br>
run in a local thread consuming CPU. As long you don't implement your <br>
own custom queuing mechanism for CE this will not change and will not scale.<br>
* Folder rules are always running in a local thread and consume CPU <br>
unless they only create a job in a queue somewhere. Choosing "async" in <br>
a folder rule only means that it should run in a independant transaction<br>
* storing a node first without OCR means always to store the same doc at <br>
least twice which is not wanted/required in most cases.<br>
<br>
To make the long story short:<br>
You could avoid a lot of hastle not to involve Alfresco at all for doing <br>
the OCR. For our customers we do all the processing and automation <br>
outside of alfresco. To create renditions or replace the content <br>
property of a node we implemented our own queuing mechanism delegating <br>
the transformation to a professional transforming engine using REST <br>
which includes PDF handling (OCR, data extraction, PDF/A validation, <br>
optimization). But as said we try to run that transformation before we <br>
store the doc iside of Alfresco.<br>
