When setting up a G/Technology environment, one of the boring things always is getting your ConnectionConfigurationMap.ccm right. One way to see what ddc-file is causing you trouble is use sysinternals Process Monitor tool and see what the last ddc-file read by the G3E-executable was. The next file immediately following that file in your ConnectionConfigurationMap.ccm then is the cause of your problem. This approach works but is very boring and can take a lot of time. Therefore, I created a tool called ‘ccmReader’ which stands for ConnectionConfigurationMap Reader and its soal purpose is to check the validness of a ConnectionConfigurationMap.ccm file.
CcmReader’s usage is as follows :
ccmReader [-v] [-l] [-c CONF] [-dumplang] [-showlang] [-help] ConnectionConfigurationMap.ccm
So what does it do ? Let’s say you have the following ConnectionConfigurationMap.ccm section and the F152-DetailVerwijzing.ddc file is missing:
CcmReader then would output the following :
The output tells you that there are two files which should be present according to the ConnectionConfigurationMap.ccm file but could not be read :
d:MAPFILESGEOSDDC9.4F152-DetailVerwijzing.cdt. So without even trying to start G/Designer, Netviewer or G/Netplot you know it will not work since your configuration is wrong and you need to fix it. Once you have corrected the errors and each file can be found, the tool will not output anything unless you used the verbose (-v) flag :
I use this tool very often in my day-to-day work, and it comes in very handy.
You can download the executable here.
Hope this helps, Stephan
