Configuration Change History Support in DBDOC 10.7

Archived Text File Dumps of Configuration and CLD / CAD Source

DBDOC now reports the specifications that make up the configuration of an INFI 90 system in text files we termed "DMPCFG".  We use these dumps to cross-check DBDOC handling of the CLD and CAD files, verifying that we handle the CLDs and CAD sheets the same as the ABB compilers Composer and WinCAD (and DOS CADEWS and SLAD).

DBDOC 10.6.1 introduced the creation of DMPCFG files for both the .CFG files and the CLD and CAD sheets automatically when you do a DBDOC build.  Read about them here.

DBDOC 10.7 introduces automatic archiving of the files from both the CLD / CAD sheets and the compiled or saved CFG files. When you do your DBDOC build, your DMPCFG files will now be archived with the error files. Also, the last build you did before installing 10.7 will be archived. Thus, you will start with a base for comparison of the last build you did with DBDOC 10.6.1 and the first with DBDOC 10.7.

Changes from Date to Date

The simple application of the DMPCFG file archives is comparison and documentation of changes in blocks and specifications from any DBDOC build dates. The following examples show how any differences will be clear.

This example shows the changes made in a module in the space of three months. Having them available like this will allow them to be cross-checked against the management of change documentation. The symbol "<" indicates the old value, with ">" showing the new blocks and specs.

What Next?

This is a respectable first step, but of course these are text files, generated during a DBDOC build, and not nearly as accessible as they could be.  We would like to see support for interactive viewing and browsing of Management of Change information from right inside the Hyperview browser.

Andrew McKeown of Oji Fibre Solutions in New Zealand suggested:

• My biggest need is around Management of Change. Knowing what has changed between each snap-shot build is an important part of managing and reconciling or even tracing changes between successive builds or across a period of time.  My contention was always that if you have the information about what is there then we should do something about seeing what has changed in detail.
• My contention now is that you could build this into the M14 by changing the file contents so that the differences could be seen in the MoC list [showing] the change and also the hyperlink to the CAD sheet and Block.

As far as comparing from version to version arbitrarily, Andrew also sets the bar very high:

• The trick then becomes what do you choose as the previous version to compare to [with] CFG and EWS CFG as sources plus the previous versions of the same.
• Archiving files for comparisons to previous versions for an ad-hoc datetime difference is all well and good but you need to make this interface easy for the user.

We concur, and are starting on this and more now. The ideas of our clients will help us.  There was a time when the errors DBDOC found during builds were available only via build-level log files, but now the Hyperview Error Browser makes this information highly accessible, and links it effortlessly into graphics and configuration.  There isn't any reason why Management of Change information, changed specs and so on, couldn't be presented in Hyperview in an analogous fashion.

Would this be useful to you?
