Creating a syndication relationship

To set up syndication between libraries on two IBM® Web Content Manager applications, establish a relationship between a syndicator and a subscriber. The syndicating server contains the data to be replicated, and the subscribing server receives the replicated data.

Important:
  • To syndicate a library that contains more than 10000 items, update the maximum Java heap size used by the portal application server on the subscriber server:
    1. In the WebSphere® Integrated Solutions Console, navigate to the Java virtual machine settings.
      Stand-alone server:
      Servers > Server Types > WebSphere application servers > WebSphere_Portal > Java and Process Management > Process definition > Java Virtual Machine
      Clustered server:
      System administration > Deployment manager > Java and Process Management > Process Definition > Java Virtual Machine
    2. Update the value in the Maximum Heap Size field. A value of at least 1024 MB is recommended.
    3. Click OK, and then save your changes.
  • You can syndicate only between servers running the same version. You cannot syndicate between versions. For example:
    • You can syndicate between versions 8.0.0.0 and 8.0.0.1.
    • You cannot syndicate between versions 7.0.0.0 and 8.0.0.0.
  • Ensure that you have at least as much swap space allocated on the subscriber server as you have physical memory.
  • First-time syndication to an existing library is not supported. If you attempt to syndicate a library to a subscriber that already has a library with the same name, an error results.
  • Information about a Library is only syndicated the first time syndication occurs and not on subsequent updates and rebuilds. If a library is renamed or library user access is changed, this information is not syndicated to the Subscriber.
  • If you change the name of a library or change user access to a library, these changes are not syndicated. If you want the same settings on all your syndicated libraries, you must manually make the same changes to any subscriber libraries.
  • If content from one library (Library A) uses an item from another library (Library B), you must include both libraries in the syndicator. Including both libraries ensures that all items are syndicated successfully.
  • If you include only Library A in the syndicator, any items in Library A that reference items in Library B are not syndicated. Syndication errors are also generated.
  • If you add a library to a syndicator after the initial syndication, you must click Update to force the new library to be syndicated immediately.
  • If you are creating a two-way syndication relationship, you must use a consistent syndication strategy. For example, if syndicating "All items", then both syndication relationships must be syndicating "All items".

To set up a syndication relationship, complete the following steps:

  1. Ensure both the subscriber and syndicator are running and that they can access each other over a network.
  2. On your subscriber server, log in to IBM WebSphere Portal.
  3. Go to Administration > Access > Credential Vault and create a shared credential vault slot to allow you to access the syndicator
  4. Go to Administration > Portal Content > Subscribers.
  5. Click Subscribe Now.
  6. Enter the syndicator URL in the form of http://HostName:HostPort/WcmContextRoot. For example: http://authoring:10039/wps/wcm
    Note:
    When syndicating to a virtual portal:
    Using the URL context of a virtual portal:
    http://HostName:HostPort/wps/wcm/url_context
    Using the hostname of a virtual portal:
    http://VirtualHostName:HostPort/wps/wcm
  7. Enter a name for the syndicator item. This name is used for the syndicator item that is created on the syndicator server. Enter a name that helps identify the syndication relationship you are creating. This name must be unique and cannot be the same as an existing syndicator name.
    Note: To reuse syndicator names of previously deleted syndication relationships on a subscriber, you must also delete the same relationship on the syndicator.
  8. Enter a name for the subscriber item. This name is used for the subscriber item that is created on the subscriber server. Enter a name that helps identify the syndication relationship you are creating. This name must be unique and cannot be the same as an existing subscriber name.
  9. Select the credential vault slot you created previously.
  10. Click Next
  11. Select the libraries you want to subscribe to.
    1. Click Add Libraries to select a library to syndicate and the syndication type:
      Live items:
      Live item syndication is mostly used when syndicating to a staging or delivery server. The following items are syndicated:
      • Published
      • Expired
      Draft items, projects, and items in a project are not syndicated.
      Live and projects:
      Use "Live and projects" syndication to gradually syndicate projects to a staging or delivery server, rather than waiting until all items in a project achieve a published state. The following items are syndicated:
      • Published
      • Expired
      • Projects
      • Draft items in a project
      Draft items outside of projects are not syndicated.
      All items:
      All item syndication is mostly used when syndicating between servers within an authoring environment. The following items are syndicated:
      • Published
      • Expired
      • Projects
      • Draft items in a project
      • Other draft items
      • Versions
      • Deleted items
    2. Select libraries from the current list, and click Remove Libraries to remove a library from the list of syndicated libraries.
  12. Click Finish.
  13. To begin syndication, click either Update Subscriber or Rebuild Subscriber button.
