Impact of server rename on the Engineering Requirements Management DOORS Next

You might encounter issues that relate to server rename and Engineering Requirements Management DOORS® Next.

Rebase TRS and reindex Requirements Management data sources

If the server of the Engineering Requirements Management DOORS Next is renamed, as part of the post-rename steps, but before adding the DNG Resources datasource back into Lifecycle Query Engine, you must perform a full TRS 2.0 rebase in DNG. Note that these steps might take some time to complete depending on the size of your repository.

  1. Do TRS 2.0 full rebase:
    1. Open a web browser and navigate to https://RM_Server:9443/rm/admin#action=com.ibm.rdm.fronting.server.web.trs
    2. Click TRS 2.0 Full Rebase. Wait for the operation to complete before proceeding to the next step. It may take some time depending on the data size.
  2. Replace the DNG TRS 1.0 data source with the TRS 2.0 data source in Lifecycle Query Engine:
    Note: If the DNG TRS 2.0 data sources already exist in Lifecycle Query Engine, you do not need to remove and add them back again. You can just reindex the data sources.
    1. Open a web browser and navigate to https://LQE_Server:9443/lqe/web/admin/data-sources
    2. If the DNG TRS 1.0 data source exists, remove it. The DNG TRS 1.0 data source is usually named DOORS Next Generation TRS and points to https://RM_Server:9443/rm/trs. To remove the data source, select it and then click Remove.
    3. Click Add Data Source, and in the wizard that opens select the TRS 2.0 for DNG Process Resources data source. Click Finish.
    4. Repeat the previous step and add the TRS 2.0 for DNG Resources data source.

      The URL for TRS 2.0 for DNG Process Resources is https://RM_Server:9443/rm/process-trs2 and the URL for TRS 2.0 for DNG Resources is https://RM_Server:9443/rm/trs2. After the data sources are added, Lifecycle Query Engine starts building the initial indices.

    5. Click TRS 2.0 for DNG Process Resources and TRS 2.0 for DNG Resources and then click Reindex and in the dialog that opens, click Reindex again.
    6. Click OK to confirm the reindex operation.
