Calculating your requirements metrics new.png

Authors: PaulEllis, ErikCraig, MartinHenderson
Build basis: DOORS 9, Rational DOORS Next Generation 4, 5, 6.

When discussing planning of deployment topologies appropriate for your requirements management system, it is important to understand your existing system. Below details how you would calculate these numbers in order to help you decide on how to deploy your servers. This topic is tightly integrated with planning for multiple requirements management instances and the sizing strategies which are intended to be used to calculate the maximum sizes of each instance.
In November 2015, a white paper was published on how to migrate data from Rational DOORS to Rational DOORS Next Generation. This should be studied alongside this page, indeed, this page is supplementary information on how to derive your existing data shape when approaching a migration.

Using Migration Metrics with Rational DOORS 9

As documented in the developerWorks article, the DOORS migration metrics utility is used to perform harmonization and consolidation of types. Reports of attributes and enumerations are examined and those that are similar or vary only by case of name must be identified and classified as intentional or in need of harmonization. Our needs at this point though are purely to derive the outlines of the data shape in terms of numbers of requirements objects.

To achieve this, then simply download the DOORS 9.6.1.3 (or later) client and install this on a machine which doesn't currently have a DOORS 9 client. This restriction is due to DOORS 9 only supporting one client per machine. If you only have access to one machine, then you can uninstall your existing client and then reinstall after completing this procedure.

There are further options available within the Migration Metrics with later releases of DOORS 9, so it is advisable to download the latest to avail of the latest possibilities. See Gathering migration metrics for the latest and complete instructions if desired.

Use the Migration Metrics utility in IBM Rational DOORS to gather information on whole projects or selected modules within a project. In the DOORS 9.6.1.3 client select:

  1. Select a project in the database explorer.
  2. Click File > Migration > Migration Metrics.
  3. In the Migration Metrics window, select the project and scope, including the entire project or selected modules.
  4. Click Go to create the migration metrics output

Note: The Migration Metrics utility is not for an entire DOORS database. This allows analysis per project or per sub-partition which in turn allows you to size the migration into Rational DOORS Next Generation more easily. This page though is not intended to discuss the migration process in detail, merely how you would count your requirements metrics.

Using SPARQL queries to obtain your metrics from DOORS Next Generation

Firstly, before running these queries please note that some of these may take some time to complete. Whilst they will not interfere too much with your production service, it is recommended that you run these during quieter periods where few users are likely to compete for query resources. Where repositories are large, then these queries could take 10 minutes. Therefore warnings of queries exceeding 45 second limits may be recorded in the rm.log.
To identify the number of artifacts within a specific project you can run a SPARQL query. SPARQL queries can be executed on the RDNG built-in administration panel https://<server>:<port>/rm/rmadmin, Under Debug > SPARQL Query. Alternatively you can go immediately to https://<server>:<port>/rm/admin#action=com.ibm.rdm.fronting.server.web.debugQuery

In the query window, set the custom SPARQL query scope to the project and check pre-count. Run the following query artifactcount.jpg

Under the results column you would see 1/xxxxx where xxxxx is the number of resources in the project the query is being run against.

To determine the number of links replace rm:Artifact with rm:Link in the above query.

For types, ordered rdf:type descending, append the PREFIX statements above to the following SPARQL SELECT statement: <\br> Check 'pre-count' and run: <\br>

SELECT ?type (count(?type) as ?foo )
WHERE {
    ?resource rdf:type ?type .
}
GROUP BY ?type 
ORDER BY DESC(?foo)

For a count for a specific Artifact Type, substitute the following. Ensure that "Artifact" is replaced with the name of your artifact type.

SELECT (COUNT(*) AS ?no )
WHERE {
    ?resource rdf:type <http://www.ibm.com/xmlns/rdm/rdf/Artifact> .
    ?resource ?p ?o
}

Alternatively, select all by Artifact Type:

SELECT ?type (COUNT(*) AS ?no )
WHERE {
    ?resource rdf:type ?type .
    ?resource ?p ?o
} GROUP BY ?type
ORDER BY DESC(?no)

Resources and Triples by Artifact Type:

SELECT ?type (COUNT(*) AS ?no ) (COUNT(distinct ?resource ) AS ?graphs )
WHERE {
    ?resource rdf:type ?type .
    ?resource ?p ?o
} GROUP BY ?type
ORDER BY DESC(?no)

Full triple count:

SELECT (COUNT(*) AS ?no ) 
WHERE {
    ?s ?p ?o
}
