Nuxeo Server

Upgrade from 5.4.2 to 5.5

Updated: September 22, 2017 Page Information Edit on GitHub

For the general upgrade process, see the How to Upgrade Nuxeo page.

This chapter presents the detailed process to upgrade from Nuxeo 5.4.2 to Nuxeo 5.5. Most of it is useful information you need to have to fully understand what has changed in this release.

Installation & Configuration

Follow Installation Instruction.

Under all OS:

  • H2 Embedded database is not supported for data detection.
  • After the installation, uncomment the line custom.target in your template/custom/nuxeo.default and set it to "." to indicate the path of your custom templates.
  • "session.timeout" has been added to nuxeo.conf and can be overridden for defining the web session timeout which is then integrated into the web.xml file.

Under Linux:

  • The new installation changes the opt/nuxeo content location to /var/lib/nuxeo/server - templates and conf still in etc/nuxeo folder.
  • The package Debian autoconfigure

    • detects your data,
    • detects/adds your marketplace addons (including DM,CMF,DAM).

Under Windows:

  • Windows installer:

    • detects your data,
    • detects/adds your marketplace addons (including DM,CMF,DAM).

Packaging

The DM, DAM, SC, and CMF distributions are now available as Marketplace packages.

This new packaging system is used in the Setup Wizard to allow to choose between different profiles at installation time. You can also use the Admin Center or the nuxeoctl commands to add or remove these packages. For projects having a custom distribution based on one of ours, no problem, we provide presets for automatically transforming the new unique Tomcat distribution into a DM, DAM or CMF. Also, the "EAR" (zip) assemblies do still exist.

Using the wizard is just an additional option.

Digital Asset & Case Management

For now, it is not possible to install CMF with other packages like DM and DAM because there are some content model incompatibilities.

Distribution

Regarding to custom distributions and related to the new 5.5 packaging (DM, CMF, DAM are now addons), Ant assembly script (assembly.xml) has to be modified:

Deploy the Nuxeo CAP distribution (only nuxeo-cap classifier still exists):

<!-- Deploy CAP distribution -->
    <unzip dest="${stagedir}">
      <artifact:resolveFile key="org.nuxeo.ecm.distribution:nuxeo-distribution-tomcat:${nuxeo.version}:zip"
                            classifier="nuxeo-cap" />
    </unzip>

${stagedir}: distribution parent folder

Define type distribution:

<!-- Set the addon deploying in distribution -->
    <copy file="${app.path}/nxserver/data/installAfterRestart-?.log"
      tofile="${app.path}/nxserver/data/installAfterRestart.log"
      overwrite="true" />

${app.path}: define your distribution path (ie ./stage/nuxeo-custom-server)
?: DM,DAM,CMF,SC

Optional: choose the wizard distribution type by setting wizard addon preset (NXP-8031):

<!-- Set the wizard.preset by default -->
    <echo file="${app.path}/setupWizardDownloads/packages-default-selection.properties"
          message="preset=nuxeo-?" />

${app.path}: define your distribution path (ie ./stage/nuxeo-custom-tomcat)
?: dm,cmf,dam

Third party libraries upgrades

  • GWT - Nuxeo is now using GWT 2.4.0.
  • JAX-WS - Libraries have been upgraded to 2.2.5 in order to fix some compatibilities issues.
  • OpenCMIS - Nuxeo Platform is now aligned on OpenCMIS 0.6 that comes with experimental support for the CMIS Browser binding (JS compliant API).
  • JEXL - Location is changed from Nuxeo Runtime to Nuxeo Platform Action.

Data Migration

VCS

Only fews column additions were done between 5.4.2 and 5.5 (no alter). So you can migrate and retrieve all your 5.4.2 data after 5.5 installation.

For relations, these attributes are added to the "relation" schema (NXP-7962):

<xs:element name="predicate" type="xs:string" />
<xs:element name="sourceUri" type="xs:string" />
<xs:element name="targetUri" type="xs:string" />
<xs:element name="targetString" type="xs:string" />

A new metadata has been added to follow the legacy definition of dublincore schema (NXP-7884) :

<xs:element name="publisher" type="xs:string"/>

A new schema has been added: task.xsd (related to the nuxeo-platform-task feature - NXP-7852):

<xs:element name="actors" type="nxt:stringList" /> (Task actors list)
<xs:element name="task_variables" type="nxt:task_variables" /> (tasks vars list)
<xs:element name="taskComments" type="nxt:taskComments" /> (Task comments list)

(Four new tables due to complex types added.)

Fulltext

Partially missing fulltext index for the title field

Old versions of Nuxeo DM might have existing documents present before the introduction of the "fulltext_title" index. This is visible on the Nuxeo 5.5 release thanks to the new search suggestion widget that might be missing some suggestions on old documents.

To update the title fulltext index, just perform the following SQL query on your PostgreSQL server:

UPDATE fulltext SET simpletext_title = NX_TO_TSVECTOR("dublincore"."title") FROM dublincore WHERE "fulltext"."id" = "dublincore"."id";

In Nuxeo 5.5 for PostgreSQL we've added a better way to store fulltext information that enables the use of phrase search. If you want to use phrase search, you should follow the upgrade notes of NXP-5689. If you do this fulltext upgrade, you may want to check the (unsupported for now) nuxeo-reindex-fulltext plugin to get more accurate phrase search results.

If you don't do the upgrade described in NXP-5689, you'll get the following error message:

Cannot use phrase search in fulltext compatibilty mode. Please upgrade the fulltext table: ...

Directories

Directories with auto-incremented columns must be upgraded, as the mechanism for auto-increment has been changed to be more robust. Please follow the NXP-7124 upgrade notes if you have auto-incremented columns (there aren't any in a default Nuxeo installation).

Code Migration

Nuxeo 5.5 is mainly backward compatible with Nuxeo 5.4.2. If you have any problems, you can contact Nuxeo Support.

Automation

Changes in Nuxeo Automation: there was a Java package renaming from org.nuxeo.ecm.automation.client.jaxrs.model to org.nuxeo.ecm.automation.client.model.

Nuxeo Theme

Nuxeo Theme service has been extended so that you can now contribute page styles in a plain CSS stylesheet. The page layouts are still managed by the Theme engine using an XML description, but all CSS information is now externalized to CSS stylesheets that can manage flavors (pretty much as with LessCSS).

Tasks

Until 5.5, the Task system was directly bound to JBPM. Starting with 5.5, a new TaskService is available and uses VCS to store tasks. This new TaskService is a first step towards the integration of Content Routing as the default Workflow engine in DM.

Migration should be 100% transparent:

  • the Task Operations have not changed,
  • REST APIs are maintained,
  • Tasks created in jBPM and not directly associated to a process will be automatically migrated upon first access,
  • jBPM Tasks are still accessible via the new TaskService,
  • the jBPM task API is maintained.

Relations

The new default configuration takes care about compatibility so that if you have existing relations in Jena graph you will still be able to transparently access them.
