Managing data providers for Lifecycle Query Engine
After you install and configure Lifecycle Query Engine to index the data from the lifecycle management tools, you can check the status of each connection on the Data Providers page. You can also view and modify the properties of your data providers, reindex, or add more data providers. If you deploy LQE across several nodes, you can view detailed status for each node.
About this task
http://<host_name>:<port>/lqe/web/admin/data-sources
you
can run various operations: Procedure
- To add a data provider, click Add Data Provider.
- To modify the properties of a data provider, click the name of the data provider, and then edit the settings.
- To validate a data provider, click name of the TRS feed in the list, and then click Validate. This task compares the TRS feed with the LQE index to ensure that the data in the index is up to date.
- To reindex a data provider, click the TRS feed name in the list, and then click Reindex. Depending on the amount of data, indexing for the first time or reindexing a data provider can take a long time.
- To check the status of a data provider on a particular LQE node, click the status link and select the node. If the data provider update fails, review and correct any errors. On the History tab you find statistics about the operations that ran for the data provider you focus on: initial indexing, validation, reindexing, cleanup, or removal activities.
What to do next
Sometimes indexing completes with errors. Often these are problems in the TRS feed, or they are related to network connectivity issues. If LQE encounters issues during indexing, it skips resources. These skipped resources are not the result of errors or problems with LQE; they can occur for many reasons including socket timeouts, bad resource definition from the data providers, invalid RDF from the data providers, or temporary internet outages.
When LQE cannot index a resource from a data provider, it skips that resource and generates an error in the lqe.log file. By default, LQE makes only one attempt to index each resource before skipping it. The number of times LQE must attempt to index can be increased for a specific data provider by changing the corresponding Number of retries property. Increasing the number of retries makes indexing and updates slower for that data provider. Skipped resources are normal and expected, particularly with network or connectivity issues. To determine what is causing the data provider issues, you can contact support for the affected data provider tool.
- To review a list of skipped resources for a particular data provider, on the Data Providers page, click Up-to-date.
- On the Data Provider Status page, click the Skipped Resources tab and review the messages to determine if the skipped resources are caused by network issues or by possible product issues.
To ensure the integrity of the TRS feed data, and to troubleshoot missing or added artifacts, you can run validation. Validating the LQE index compares the current TRS feed from a IBM® Engineering Lifecycle Management application with the LQE index. Validating a TRS feed compares the current TRS feed to the data in the application repository. For more information, see Validating TRS feeds and the LQE or Link Index Provider index.
