When you add a new node to your deployment after installing IBM® Connections, you need to manually
create Search work managers for the newly-added node.
About this task
When you install IBM Connections,
the following work managers are automatically created for Search on
each node in your deployment:- SearchCrawlingWorkManager
- Handles the work involved in crawling the seedlists to persist
them to disk.
- SearchDCSWorkManager
- Handles the work for the file content retrieval and conversion
task.
- SearchIndexingWorkManager
- Handles the work involved in processing the entries in persisted
seedlists into Lucene documents.
If you subsequently add a new node, you need to
create these work managers manually. For more information about creating
work managers, see the WebSphere Application Server information center.
Procedure
To create work managers for Search, complete the following
steps.
- Open the IBM
WebSphere® Integrated Solutions Console.

from the All scopes list and then click New.
Note: The scope should be the node itself, not the server running on the node. For example, "Node1",
not "Node1, InfraCluster_server1".
- Enter one of the following display names in the Name field:
