Moving Cradle Projects

Are you upgrading/updating your servers? Here we explain moving Cradle projects from an old server to a new server. There are two ways to do this:

  • Moving projects to a new server with the same Cradle version
  • Moving projects to a new server and upgrading to a new Cradle version

Both of these scenarios are detailed below.

Please note if users have Personal definitions, e.g. if they are are using Sessions, these will either need to be copied or exported and imported to the new server. Personal definitions are located in $CRADLEHOME\admin\definitions\personal and the folders have the users names. If copying the definitions they need to be placed in the same location within the personal folder.

New Server with Same Cradle Version

If you are not upgrading Cradle at this time, this is really simple to do.

  1. Create the Cradle projects on the new server with the same project code as previously created on the old server. Ensure the pathname is the location where the databases will be stored.

    Create Project dialog
    Create Project dialog
  2. Copy the contents of the Cradle projects on the old server to the new server. The directory contains all of the data including user profiles, project setup, definitions etc.
    Explorer showing project contents
    Project Contents

    New Server with New Cradle Version

If you are upgrading the Cradle version as well as migrating to a new server, this is slightly more complex.

The safest method (although can be time consuming) is to create export files of the existing Cradle databases and then import them into the new server installation.

  1. When exporting the information from the “old” server, ensure Owner is set to Everything as shown below:Export Information dialog showing Owner option
  2. Once the new version of Cradle has been installed on the new server, you need to create the Cradle projects on the new server.
  3. In the new project you can then import the data exported from the old server . When importing, ensure Owner is set to As in file, Overwrite is set to On and the top four validation checkboxes are selected:Import Information dialog showing import options
  4. Repeat this for all projects

Another way to achieve this is to copy the project directories from the old server on to the new server and then manually convert the projects.

  1. Create the Cradle projects on the new server with the same project code as previously created on the old server with the pathname being the location where the databases will be stored.

    Create Project dialog
    Create Project dialog
  2. Copy the contents of the Cradle projects on the old server and overwrite the contents of the newly created projects on the new server. The directory contains all of the data including user profiles, project setup, definitions etc.
  3. Manually run the necessary converters to ensure the new projects are in the same format as the new Cradle version installed. Please note this may be several converters if converting from a much older version.

Note: Please ensure the projects have been converted BEFORE logging in.

Showing Cell Titles in Views

Sometimes when displaying a nested view the cell titles take up a lot of space on the screen.

Displaying Cell Titles
Displaying Cell Titles

Within the View Details dialog you have the option to choose whether you want to display the cell titles:

Show cell titles option
Displaying cell titles in views

As you can see you can choose to either:

  • Show the cell titles
  • Hide the cell titles
  • Show the cell titles only when the view is top-level

You can change the visibility of any of the component views that are being used to show linked items. In practice, most people either hide everything or show everything.

For further information on views please see our online help page.

National Radio Day

20th August – National Radio Day

Individuals/communities can take National Radio Day as an opportunity to appreciate/celebrate what radio means to the world today. Some people might think radio has passed its prime.  Although it still acts as a strong force, especially for local communities.

The first person to identify radio waves was a German physicist Heinrich Hertz in 1886. But it took about three decades for a practical receiver to be invented, which was due to the work of Italian inventor, Guglielmo Marconi. Though it started with a Morse code message from just a kilometre away, Marconi paved the way for the future of the types of messages that radio waves could carry.

Cradle can be used to model radio systems, see the Cradle Physical Architecture Diagram (PAD) below which depicts an External Communications Sub-System:

Differences between a Baseline and a Snapshot

Trying to decide on whether baselines or snapshots are best for your project? Here we explain the differences so you can make the informed decision on which is best for your project.

What is a Baseline?

A baseline is a mechanism in a Configuration Management System to protect formally reviewed and approved information from modification. It is a named repository for the definitive state of a system at a specific point in time to which only read-only access is permitted. A succession of baselines can be created over the life of a project, each containing information from an increasing subset of the phases in a project.

Principles of baselines
Principles of Baselines

When a new baseline is created, unchanged items will migrate into it from the previous baseline.  Therefore new copies of items are not created for each new  baseline. This avoids such copied items increasing the number of items in the database and hence the database size.

These are a collection of the accepted/approved items that can be reported / queried / viewed in numerous ways.

The items are progressive in that each instance of an item is controlled by the Version attribute and “work in progress” items are labelled with a draft “A”

Baselines only contain the data. Not the definition files that existed at that time (e.g. views, queries, documents, reports).

What is a Snapshot?

A snapshot is a read-only copy of ALL the information in a Cradle database at a specific point in time that can be viewed, in isolation, at any point in the future.

This includes definition files (excluding Personal) and the project definition.

When a snapshot is selected, access to information, cross references and definitions is determined by the contents of the user’s profile in the database they are currently logged into, regardless of whether or not the user has a profile in the current snapshot and regardless of the contents of that user profile (if any) in the snapshot.

Select Snapshot
Select Snapshot dialog

Snapshots can be deleted from Project Manager or via command line (as power user).

August 2022 – Newsletter

Cradle-7.7 – Released

We are pleased to announce the release of Cradle-7.7 which is available now for download from the downloads section of the 3SL website.  This is the latest version of Cradle.

Cradle-7.7
Cradle-7.7 splash screen

3SL customers with active maintenance have been sent an e-mail notification, and details of which of their enhancement requests and bug reports are included in this new release.  This is a significant Cradle release that increments the Cradle minor version number from 7.6 to 7.7. This means that the Security Codes for Cradle-7.6 or earlier will NOT work with this new Cradle-7.7 release. Therefore, if you want to upgrade to Cradle-7.7 then you MUST contact 3SL Support and request a Cradle-7.7 Security Code since your existing Cradle-7.6 Security Codes will NOT work with this new release.

New Cradle-7.7 Capabilities

This release contains a range of new capabilities, including:

  • Snapshots
  • Metrics added to graphs
  • New header option in views
  • New reports
  • Annular dial type added to Dashboards
  • Precision option added to Dashboards
  • Ability to test email setup from User Preferences

These new capabilities are shown below. For further information please refer to the Release Notes.

Snapshots

A snapshot is a read-only copy of all the information in a Cradle database at a specific point in time that can be viewed, in isolation, at any point in the future.

Snapshots can be created and selected from the Project tab in WorkBench:

Project ribbon in WorkBench
Snapshot options in WorkBench

Snapshots can also be created via the command line using c_prj.

When a user selects a snapshot, their access to information, cross references and definitions are determined by the contents of the user’s profile in the database, regardless of whether or not the user has a profile in the current snapshot and regardless of the contents of that user profile (if any) in the snapshot.

Snapshots are deleted from Project Manager or the command line (c_prj).

Metrics in Graphs

Cradle-7.7 includes a new type of graph which shows metric coverage or count of items with different categories set or unset. This is called a metric graph. An example is shown below:

Example Metrics Graph
Example Metrics Graph in Cradle

Header Option in Views

A new Header option is now available in the dialog. This provides a way of showing grouped and coloured headings when output. Example output is shown below:

Example Output showing coloured header
Example output from WorkBench showing a coloured header

New Reports

A new Baseline Summary List report has been included in this release. This outputs each baseline on it’s own row in a table.

The Baseline Summary report has been renamed to Baseline Summary Compact.

A Sort by filter has also been added to both the Baseline List report, Baseline Summary List report and the Baseline Summary Compact report. This provides the option to sort by the baseline name, when the baseline was opened or when the baseline was closed.

Report Details Dialog

Test Email Setup

The setup of emails can now be tested from User Preferences by selecting the new Test Email button:

User Preferences showing Test Email button
User Preferences showing Test Email button

Pressing the Test Mail button produces the Mail Test dialog where you choose an email recipient and whether you want to send the test email in plain text.

Mail Test dialog
Mail Test dialog

Please note the only user names shown in the Recipient drop down are Cradle users in the project who have an email address defined in their User Profile.

Download

You must contact 3SL for new Security Code(s) for Cradle-7.7. Cradle-7.7 will not accept Security Codes from Cradle-7.6 or any previous release.

Cradle clients (WorkBench, Web Access, Document Publisher for instance) and server (Cradle CDS) versions cannot be mixed. Therefore, you must upgrade all Cradle installations to 7.7.

Cradle-7.7 databases do not have the same format as Cradle-7.6 databases. Hence the Cradle-7.7 release includes a database converter for the transition from Cradle-7.6 to Cradle-7.7.  Full details are available in the 7.7 release notes, and updated manuals in addition you can always contact support@threesl.com .

Single User Products

Please note that there are no maintenance services for single-user Cradle products. Therefore, if you have purchased any of the single-user Cradle-7.6 products:

    • Cradle-RM Desktop
    • Cradle-RM Pro
    • Cradle-SE Desktop
    • Cradle-SE Pro

then you will not be able to request a new Cradle-7.7 Security Code. If you want to update your single-user Cradle system to the new Cradle-7.7 release, then you must buy the new Cradle-7.7 release.

Help with Cradle-7.7

In conclusion, we’re pleased with the new capabilities in Cradle-7.7 most importantly we hope you will benefit by upgrading. If you are not already a customer and would like more information about Cradle, you can download the software and a free evaluation licence, find more on our website, or request a webinar. If you would like to read some independent reviews feel free to use your favourite search engine or take a look at Capterra.

Upcoming Training Courses

We still have places available on our August Requirements Management training course. The dates are 15th to 18th August. This is a great opportunity for small teams, or a couple of new team members to get started with RM and Cradle. Don’t worry if you can’t make the August RM course, we are holding another one in November.

In September we then have our Risk Management course. Learn how to identify, analyse, evaluate, treat and monitor the risks associated with activities or events within your business. This course is designed for project team leaders or managers who administer and manage risks.

Showing Filtered “Transitive” Links in Tables

Problem

We have created some links between Cradle items but we only want to see a filtered set of these links in our table.

Rationale

Cradle has a unique ability to follow cross references transitively. This means that although an item might not be directly cross referenced from it’s source, it might be linked indirectly through another item/item type.

Cradle also has the ability to name cross references referred to as link types and even group sets of link types together referred to as link groups.

Combining these features can allow flexibility for the output of items that have some relationship to the source which will reduce the number of direct cross references required.

For example, we would like to show dependencies between item type A and item type C but ONLY those that have a yellow and blue link type.

Model showing defined Links Between Item Types
Defined Links Between Item Types

We can see in the screenshot below that only A-6 and A-11 are transitively linked to items of item type C with both a blue and a yellow link:

Showing Direct Links in a Nested Table
Direct Links in a Nested Table

Setting Link Groups

We can define a link group in Project Setup in which we can select from the available link types.

Screenshot showing how to define a link group
Defining Link Groups

This defined link group can be used in navigations.

Defining Navigations

Navigations allow us to specify how we would like to follow the links that have been created between items. This is a very powerful feature as we can also specify that we would like to follow links transitively:

Defining a Navigation to follow Cross References transitively in the Navigation Details Window
Defining Navigations to Follow Cross References Transitively

Using the Navigation in Views

We can now use the navigation to specify that we want to show links between item type A and item type C that are followed transitively but we ONLY want to show the group of links YELLOW AND BLUE. Remember that there are NO DIRECT links between these two item types. The cross references are from item type A to item type B and also from item type B to item type C:

Defining a View to allow links to be shown transitively between item
Using the Transitive Navigation in Views

Applying this view, we can see that only the YELLOW AND BLUE links are shown in the table. The remainder appear blank:

Output of a table that shows links that are transitive when they exist
View Showing Transitive Cross References

Using the Navigation in Queries

We might wish to only show items in our table that have these links in preference to showing all items and just appearing blank where the transitive link does not exist. We can achieve this in the Query Details dialog:

Using the Query Details Window to filter items that do not have any indirect transitive links
Filtering Items Non-Linked Items in a Query

This will now filter out of the list any items that do not match the navigation criteria:

Screenshot showing the resulting table that only shows items where a transitive link exists
Link Table Only Showing Items Where Transitive Link Exists

Showing Path in a Tree Style

If we followed the path in a tree style showing downward links, we can see that item type A (A-6 and A-11) are not directly linked to item type C (C-1). They go through item type B (B-2):

Screenshot showing the direct links between items in a tree style to prove that the items are not directy linked
Links shown in Tree Style

Summary

Cradle provides a unique ability to allow cross references to be followed transitively (through other items).

Transitive navigations can be applied to views and queries. This provides a very powerful filtering mechanism that allows us to show non-direct dependencies between items.

Testing Cradle on additional platforms

With the release of 7.7 coming very soon, we thought we’d test Cradle on additional platforms.

So here’s Cradle 7.7 running on a Steamdeck, in Desktop mode.
Cradle running on Steamdeck

Cradle About screen running on Steamdeck

As SteamOS is based on Arch Linux, our 64 bit Linux version can be installed.

Both the CDS and WorkBench are running on this very capable device. A keyboard and mouse may work better than the on screen keyboard.

If you install the service manager (systemd script) then the Cradle Database Server (CDS) will start on boot up of the Steamdeck, so you might not want to do that if its primarily used for Steam. However, once started the CDS will stay running in the background when you switch to Gaming Mode. If you have others connecting to your CDS then they can continue to work while you improve your hand-eye coordination in your favourite game.

Although Steamdeck is not an officially supported platform, you can see Cradle does indeed run on additional platforms

Create a New Database Based upon a Previous Database

The Problem

I want to create a new database that is a copy of a pre-existing database minus the actual data.

Cradle Project Environment

The environment for the Cradle project will contain:

  • Project Setup
  • Supporting definition files (views, forms, queries, documents etc.)
  • Users*

*If you will have the same users in the new project that are in the existing project.

The Solution

To avoid the Personal and/or User definition files being part of this import, we would suggest the following:

  1. Log in to the existing project as MANAGER
  2. Select Project > Export
  3. In the Export dialog set Owner to  Everything and Info Type to Project Schema and User Profiles (if users are required, see comment above)

Screenshot showing export of project schema and user profiles

  1. Press Export to create the export file and close the Export Status dialog but do NOT close the Export Information dialog:Screenshot showing Export Status
  2. In the Export Information dialog, change the Info Type to ONLY show Definition Files:
    Screenshot showing Export Definition Files
  3. You will see that some new options appear – Definition Type and Location:
    Screenshot showing Info Type Definitions filter in Export
  4. The Definition Type option allows you to specify the types of definition file to be included in the export. For this example, we will leave this as All:
    Screenshot showing Definition Types in Export
  5. The Location option defines which location you are exporting the definition files from.
    Users may have created Personal or User definition files that might not be relevant to the new project.
    Personal and/or User definitions might only have been useful to an individual person rather than the project so could be omitted.
    In this case, we would only need to select Team*, User Type* and Project

    * It may only be necessary to select Project

    Screenshot showing Location of definitions in Export

  6. Press the Export button again. This will present you with the option to Overwrite, Append or Cancel. Select Append:
    Screenshot showing Overwrite or Append
  7. In Project Manager, create your new project with an EMPTY schema:
    Screenshot showing Create New Empty Project
  8. Log into the new project as MANAGER
  9. Select Project > Import and set Owner to As in File and Overwrite to On:
    Screenshot showing Import Information
  10. You will see that your new project contains:
  • Users
  • All the Project Setup information including the phase hierarchy and all supporting definition files

Summary Note

If you had NOT chosen to append the definition files, it is highly likely that the phase hierarchy from the existing project would not work in the new project and would produce errors.

These definition files are important to define the WorkBench environment.

Also, if you had chosen to export all the definition files, this may have resulted in numerous views, forms, queries, documents etc., that are not particularly relevant or accepted into project definitions.
