Alfresco Scanner
Introduction
The Alfresco Scanner allows extracting object such as document, folders and lists and saves this data to migration-center for further processing. The key features of Alfresco Scanner are:
Extract documents, folders, custom lists and list items
Extract content, metadata
Extract documents versions
Known issues & limitations
Last version content is missing online edits when cm:autoVersion was false and then it's switched to true before scanning (#55983)
Install/Uninstall Alfresco Scanner
Alfresco Jobserver
The Alfresco connectors are not included in the standard migration-center Jobserver but it is delivered packaged as Alfresco Module Package (.amp) which has to be installed in the Alfresco Repository Server. This amp file contains an entire Jobserver that will run under the Alfresco's Tomcat, and contains only the Alfresco connectors in it. For using other connectors please install the regular Server Components as it is described in the Installation Guide and use that one.
The following versions of Alfresco are supported (on Windows or Linux): 4.0, 4.1, 4.2, 5.2, 6.1.1, 6.2.0, 7.1, 7.2. Java 1.8 is required for the installation of Alfresco Scanner.
To use the Alfresco Scanner, your scanner configuration must use the Alfresco Server as a Jobserver, with port 9701 by default.
Install Alfresco Scanner
The first step of the installation is to copy mc-alfresco-adaptor-<version>.amp file in the “amps-folder” of the alfresco installation.
The last step is to finish the installation by installing the mc-alfresco-adaptor-<version>.amp file as described in the Alfresco documentation:
https://docs.alfresco.com/content-services/latest/install/zip/amp
Before doing this, please backup your original alfresco.war and share.war files to ensure that you can uninstall the migration-center Jobserver after successful migration. This is the only way at the moment as long the Module Management Tool of Alfresco does not support to remove a module from an existing WAR-file.
The Alfresco-Server should be stopped when applying the amp-files. Please notice that Alfresco provides files for installing the amp files, e.g.:
C:\Alfresco\apply_amps.bat (Windows)
/opt/alfresco/commands/apply_amps.sh (Linux)
Due to a bug in older versions of the Alfresco installer under Windows, please be careful that the amp installer via apply_amps.sh works correctly!
Uninstall Alfresco Scanner
The Alfresco Scanner can be uninstalled by following steps:
Stop the Alfresco Server.
Restore the original alfresco.war and share.war which have been backed up before Alfresco Scanner installation
Remove the file
mc-alfresco-adaptor-<version>.ampfrom the “amps-folder”
Alfresco Scanner Properties
To create a new Alfresco Scanner, create a new scanner and select Alfresco from the Adapter Type drop-down. Once the adapter type has been selected, the Parameters list will be populated with the parameters specific to the selected adapter type. Mandatory parameters are marked with an *.
The Properties of an existing scanner can be accessed after creating the scanner by double-clicking the scanner in the list, or selecting the Properties button/menu item from the toolbar/context menu. A description is always displayed at the bottom of the window for the selected parameter.
Multiple scanners can be created for scanning different locations, provided each scanner has a unique name.
Common scanner parameters
Configuration parameters | Values |
Name | Enter a unique name for this scanner Mandatory |
Adapter type | Select Alfresco from the list of available connectors Mandatory |
Location | Select the Jobserver location where this job should be run. Jobservers are defined in the Jobserver window. If no Jobserver has been created by the user to this point, migration-center will prompt the user to define a Jobserver Location when saving the Scanner. Note that the Alfresco Server must be used as a Jobserver Location with default port 9701. Mandatory |
Description | Enter a description for this job (optional) |
Alfresco Scanner parameters
The configuration parameters available for the Alfresco Scanner are described below:
Configuration parameters | Values |
username* | User name for connecting to the source repository. A user account with admin privileges must be used to support the full Alfresco functionality offered by migration-center. Example: Alfresco.corporate.domain\spadmin Mandatory |
password* | Password of the user specified above Mandatory |
scanLocations | The entry point(s) in the Alfresco repository where the scan starts. Multiple values can be entered by separating them with the “|” character. Note that this value(s) needs to be according to the Alfresco Repository folder structure, ex: /Sites/SomeSite/documentLibrary/Folder/AnotherFolder /Sites/SomeSite/dataLists/02496772-2e2b-4e5b-a966-6a725fae727a The scanner allows as a scan location: an entire site, a specific library, a specific folder in a library, a specific data list. If one location is invalid the scanner will report an appropriate error to the user so it will not start. |
contentLocation* | Folder path. The location where the exported object content should be temporary saved. It can be a local folder on the same machine with the Jobserver or a shared folder on the network. This folder must exist prior to launching the scanner and must have write permissions, migration-center will not create this folder automatically. If the folder cannot be found an appropriate error will be raised and logged. This path must be accessible by both scanner and importer so if they are running on different machines, it should be a shared folder. Mandatory |
exportLatestVersions | This parameter specifies how many versions from every version tree will be exported starting from the latest version to the older versions. If it is empty, not a valid number, 0 or negative, greater than the latest "n" versions, all versions will be exported. |
exportContent | Setting this parameter to true will extract the actual content of the documents during the scan and save it in the contentLocation specified earlier. This setting should always be checked in a production environment. |
dissolveGroups | Setting this parameter to true will cause every group permission to be scanned as the separate users that make up the group |
excludeAttributes | List of attributes to be excluded from scanning. Multiple values can be entered by separating them with the “|” character. |
loggingLevel* | Sets the verbosity of the log file. Values: 1 - logs only errors during scan 2 - is the default value reporting all warnings and errors 3 - logs all successfully performed operations in addition to any warnings or errors 4 - logs all events (for debugging only, use only if instructed by fme product support since it generates a very large amount of output. Do not use in production) Mandatory |
