Planning your ELM installation or upgrade to version 7.0.x

Question & Answer


Question

How to plan your installation or upgrade to IBM Engineering Lifecycle Management version 7.0.x versus previous versions.

Cause

There are some changes to the system requirements and architectural changes that might pose a challenge in some larger or complex environments.  In particular, there is a significant change to the Engineering Requirements Management application that moves the application index from the local application server to the database repository.
Here we detail the resources are available to help plan the upgrade and provide some steps.

Answer

Here is a list of resources to get the process started:

Download, review, and complete the "ELM7 Upgrade Run Book" document template to assist with your planning efforts.

Once you have a tentative plan for scheduling your upgrade, open a Support Case with the following information:

  • What version of ELM you are currently running, including any patches applied?
  • What version of ELM you are upgrading to?
  • When do you plan on performing the upgrade?
    • In QA?
    • In Production?
  • What database server vendor are you using?
    • What version are you currently running?
    • How large are your Application databases?
  • Which ELM applications are you running?
  • Are any of your applications clustered?
  • Do you currently have Rhapsody Design Manager installed?
    • If so, is it colocated with Engineering Workflow Management or distributed?
  • Which Operating Systems are your servers running?
    • What version?
  • How large are the Application indexes?
    • This information can be obtained by calculating the size of the <JAZZ_HOME>/server/config/<app> directory.
  • Are Global Configurations enabled?
    • Is the Global Configuration Manager deployed?
    • Do you have projects that are enabled to use Global Configurations?
  • If you are using Engineering Requirements Management, include the output of the following query from your database. 
  SELECT 'concepts' AS metric, COUNT(DISTINCT CONCEPT) AS value FROM VVCMODEL.VERSION  UNION ALL  SELECT 'versions' AS metric, COUNT(DISTINCT VERSION) AS value FROM VVCMODEL.VERSION  UNION ALL  SELECT 'configs' AS metric, COUNT(*) AS value FROM VVCMODEL.CONFIGURATION   UNION ALL  SELECT 'changesets' AS metric, COUNT(*) AS value FROM VVCMODEL.CHANGE_SET   UNION ALL  SELECT 'version mappings' AS metric, COUNT(*) AS value FROM VVCMODEL.VERSION   UNION ALL  SELECT 'resources' AS metric, COUNT(*) AS value FROM RESOURCE.RESOURCE   UNION ALL  SELECT 'resource revisions' AS metric, COUNT(*) AS value     FROM RESOURCE.RESOURCE res     INNER JOIN REPOSITORY.ITEM_STATES states      ON states.ITEM_UUID = res.ITEM_ID  UNION ALL  SELECT 'item states' AS metric, COUNT(*) AS value FROM REPOSITORY.ITEM_STATES
  SELECT 'concepts' AS metric, COUNT(DISTINCT CONCEPT) AS value FROM VVCMODEL_VERSION  UNION ALL  SELECT 'versions' AS metric, COUNT(DISTINCT VERSION) AS value FROM VVCMODEL_VERSION  UNION ALL  SELECT 'configs' AS metric,  COUNT(*) AS value FROM VVCMODEL_CONFIGURATION  UNION ALL  SELECT 'changesets' AS metric, COUNT(*) AS value FROM VVCMODEL_CHANGE_SET  UNION ALL  SELECT 'version mappings' AS metric, COUNT(*) AS value FROM VVCMODEL_VERSION  UNION ALL  SELECT 'resources' AS metric, COUNT(*) AS value FROM RESOURCE_RESOURCE  UNION ALL  SELECT 'resource revisions' AS metric, COUNT(*) AS value     FROM RESOURCE_RESOURCE res     INNER JOIN REPOSITORY_ITEM_STATES states     ON states.ITEM_UUID = res.ITEM_ID  UNION ALL  SELECT 'item states' AS metric, COUNT(*) AS value FROM REPOSITORY_ITEM_STATES
  • Once completed, attach a copy of your ELM7 Upgrade Run Book to the Support Case
