Connecting to a TRS provider on the same JTS as a data source for the LQE index

Any lifecycle tool which supports the TRS specification can be used as a data source to create the Linked Lifecycle Data Index. This topic describes how to generate the index for a lifecycle tool sharing the same JTS as LQE.

Before you begin

The LQE functional user (lqe_user) must created in the JTS for the lifecycle tool, as described in Configure LQE in the JTS administration console

About this task

If LQE and the lifecycle tool you are indexing share the same JTS, configuring LQE to use it as a data source is very simple since JTS can share a lot of the configuration data.

For more complex topologies in which there are multiple JTS servers, refer to one of the following topics:

Procedure

  1. In the LQE administration panel, select the Data Sources panel. This panel shows the live status of any data sources LQE is connected to.

  2. Select Add Data Source.

    1. The data sources who share a JTS with LQE are listed in a format similar to: https://server:port/tool/trs. Select the data source you want to add.
    2. Add a label as an identifier for the data source.
    3. The scheduling fields allow you to set when the initial indexing will occur. Leaving the fields blank will result in the index being created as soon as the wizard is finished. In a test lab environment LQE can index 50 000 artifacts in less than 1 hour - depending on your hardware and configuration you may experience a slower indexing rate.
      Note: You can index multiple data sources simultaneously. Each one will run on its own thread. Alternatively you can schedule the initial indexing of multiple TRS data sources to run one after the other.
    4. For tools using the same JTS as LQE no authentication should be necessary. If you want to change the authentication type you can choose to specify the authentication.
  3. Select your data source configuration options.

    1. The refresh rate specifies how often LQE attempts to access the data source for ongoing refreshes of its index. A data source which is not updated frequently can have a slower refresh rate than a data source which is updated continuously. Increasing the refresh rate will have a performance impact.
    2. The number of threads for the initial indexing should generally be set to between 2 and 4. Each thread is roughly equivalent to one user using the LQE server. For Intel machines, the rate of improvement in data retrieval speed for more than 4 threads is minimal.
    3. The number of threads for the ongoing indexing should generally be set to between 2 and 4. Each thread is roughly equivalent to one user using the LQE server. For Intel machines, the rate of improvement in data retrieval speed for more than 4 threads is minimal.
    4. Continue with incremental update in case of skipped resources allows LQE to log an error and continue indexing when it encounters a resource it cannot index. This is selected by default. If it is disabled, the indexing process will stop any time a resource cannot be indexed.
  4. Once you finish the wizard you will be shown the data that can be configured at any point for this data source. Click Save to begin the indexing. The live status of the indexing process is displayed in the main Data Sources panel. Clicking the link in the status field will display an in-depth status report for the indexing process.

What to do next

If at any point you need to stop indexing a data source or pause your indexing process, in the main Data Sources window hover over the Actions field to display the icons for pausing, stopping or deleting an index.
