Cradle-5.2
3SL is pleased to announce the immediate availability of Cradle-5.2, the new major release for our requirements management and systems engineering environment. Cradle-5.2 offers a major increase in functionality from previous releases. It is a full Cradle release, and is accompanied by new documentation and related materials.
Our website has been updated to allow the download of Cradle-5.2 as well as the previous Cradle releases.
The major elements of the Cradle-5.2 release are: |
- Support for Project Unique IDs (PUIDs)
- Support for auto-numbering of requirements and user-defined item types
- New Software Architecture Diagrams (SADs)
- Improved native Windows look and feel in WorkBench
- Text editing, undo and redo facilities in WorkBench forms
- HTTPS support for the Cradle Web Access facility
- Extensions to phase hierarchies
- Substantial extensions to diagram editing
- Hierarchy Diagrams (HIDs) support one, several, or all destination item types
- Standalone installation mode
- Support of Citrix and Microsoft Terminal Services technologies
- Performance enhancements and resistance to DOS attacks
Database Compatibility
Cradle-5.2 has a new format for its project databases. If you upgrade to Cradle-5.2 you must convert all of your project databases to the new format. A converter is supplied with the release that will perform all of the conversions for you. The need to run this converter is detected automatically by the Cradle-5.2 installers to ensure that the process is as smooth and transparent as possible.
Previously, it has also been possible to upgrade to a new release by creating a new Cradle installation with new project databases in new directories and using exports and imports to move data between the databases of the old and new versions. With this approach, you could use the new version and its databases, or you could revert to the old Cradle version and its databases. These sets of databases would have the same contents, but this would remain true for so long as data is not changed in one set that is not also changed in the other.
Users who adopted this approach used a procedure similar to: |
- Export data from the databases in the previous release
- Install the new release
- Create new projects in the new release
- Import the data from the previous release projects into the new databases
If you have not used change histories (edit histories) in Cradle-5.1 (or any of its updates), then you can still use this approach, if you wish.
However, if you have used change histories (edit histories) in Cradle-5.1 (or any of its updates) then you must use the converter to upgrade to Cradle-5.2.
The reason for this is that at Cradle-5.2 we changed the way change histories (edit histories) are stored. Prior to version 5.2, they were stored as events in the project Configuration Log used in the Cradle Configuration Management System (CMS). From version 5.2 they are stored in CHANGE HISTORY frames in the items in the database. Therefore, simply exporting and importing will not convert the change history information from the Configuration Log to CHANGE HISTORY frames, and so if you simply export from Cradle-5.1 and import into Cradle-5.2, then you will lose your change history information when viewed through Cradle-5.2.
Toolset Fonts
Cradle-5.2 includes changes to the set of fonts used by the Cradle Toolset.
If you upgradeto Cradle-5.2 from Cradle-5-1 or an earlier version, then you must apply the new fonts supplied with Cradle-5.2.
Must I Install Cradle-5.2?
Cradle-5.2 contains all the enhancements and bug fixes from the Cradle-5.1.3 and Cradle-5.1.2 updates to Cradle-5.1 and a set of further enhancements. It represents a very substantial improvement over Cradle-5.1.
We would like you to use Cradle-5.2 in preference to Cradle-5.1, Cradle-5 or an earlier version. That is why we released it!
If you are currently using Cradle-5.1, there is no immediate need for you to upgrade to Cradle-5.2. 3SL will continue to support Cradle-5.1 and its updates ( Cradle-5.1.2 and Cradle-5.1.3) until the next major version of Cradle is released.
However, if you are currently using Cradle-5, or Cradle-4, then we strongly urge you to upgrade to Cradle-5.2: |
- You will see some very dramatic extensions and improvements
- 3SL no longer supports these releases
Downloading Cradle-5.2
All Cradle-5.2 download files for Windows and UNIX in our website were added to our website on 9 th August March 2005.
For Windows, the file to download is: Cradle52_Setup.exe
For UNIX, download the boot and core.Z filesets, and also download the fileset for your architecture:
- hp700_10 or hp800_10 for HP HP-UX 10.20 or later
- ibm4 for IBM AIX 4.2
- ibm5 for IBM AIX 5.1 or later
- linux-ia32 for all compatible versions and types of Linux
- sparcs2 for Sun Solaris 2.5.1 or later
- win32pc for Windows executables hosted on a UNIX server
|
So, if you are running on UNIX, you will need to download a minimum of 3 filesets.
If you are running a UNIX server that provides executables for multiple platforms, then you will need to download boot, core.Z and all the filesets for the platforms provided by your server.
If you are running a mixed UNIX and Windows environment, such as UNIX servers and Windows clients, then you will need to download the Windows self-extracting executable and all of the UNIX filesets.
3SL has a dedicated 2 Mbit/sec Internet connection which means that even the largest of these files can be downloaded in 15 minutes. However, we also provide a mirror site, which provides even faster downloads.
