Problem when Importing ACP file

[ediez]

Hi,

I've exported a space of aprox 7GB from my repository. I did that using the Export functionality provided by Alfresco (version 3.0) and obtained an Alfresco Content Package file (acp).

When trying to import it on a different instance of Alfresco (same version -3.0-), I get the error shown below:

INFO   | jvm 1    | 2009/04/28 17:38:30 | 17:38:30,281 Tenant:ab User:admin WARN  [app.servlet.UploadFileServlet] no file uploaded for upload nullINFO   | jvm 1    | 2009/04/28 17:38:30 | 17:38:30,281 User:admin WARN  [app.servlet.UploadFileServlet] no file uploaded for upload null

It seems like the import process success for small spaces (aprox 70 MB) but it failed when attempting to import a bigger space. I'm wondering if it has a limit.

Thanks for any help you can provide on this.

Hi ediez

ACP files are techically limited in size (I've heard about 1gb). Reasons include that they can become big very fast since they contain document contents, and they are imported in a single transaction.

(shameless plug) The ETL Connector extension for Alfresco overcomes these limitations, besides having many other uses when coupled to a compatible ETL like Talend 3.1 .

Hey mdutoo,

Thanks for your reply. I managed to correctly import all my files. ACP doesn't come like a good idea for huge files (+1GB).

Thanks again.

You're welcome, anyway well done.

Note that other common import practices include scripted automated actions, or webscripts - though all this implies some coding.

The ETL connector does overcome those limitations. You also get to use Talend Open Studio with the connector, which is an open source ETL tool for data integration experts with a user-friendly GUI. It is easy to learn for a non-technical user. What distinguishes Talend, when it comes to business users, is the tMap component which allows the user to get a graphical and functional view of integration processes.

Have any you used Talend for ongoing data synchronization between a legacy system and Alfresco? I essentially need to do daily extracts from one db and copy a subset of the data into the WCM and am trying to determine if Talend will do that easily or if I need to build something custom.

Hi Bajuk,

Actually Talend is the correct solution for your needs. It can perform data synchronization. The software has connectors with Alfresco making it possible to work with both. Making a daily extract is easily achievable with Talend once the "job" has been created: you "run the job" and the extraction begins.

And even if you need something customized, you can modify the software: it is open source.
