How VCDA Handles Concatenated config.dat Files
VCDA uses information from the config.dat file, which normally contains parameters that apply to the local hostname only. However, if you want to concatenate the contents of all your config.dat files into a single config.dat file to distribute across multiple environments, VCDA manages this situation as follows:
• The hostname under which a snapshot is saved shall be saved within the snapshot.
• If VCDA detects that hostnames other than the snapshot one are managed within the config.dat information of the snapshot, VCDA shall display it.
A “hostname mapping” option is available in that situation, so that VCDA can compare the additional hostnames configuration parameters. If this option is not used, the parameters are compared including their “hostname” part, (that is, only parameters that are identical for the same hostname within the two snapshots are considered as identical).
