There is a trend within IBM to move to using DVD as the standard software install media.
There has been talk about doing this within Informix before, partly because we're close to the maximum CD size on some platforms (where more than one copy of Java Runtime needs to be on the CD for example).
One advantage moving to DVD would provide is the ability to bundle additional components, for example Data Server Driver, which provides the Comment Client API's to connect to IDS via the DRDA protocol. Currently if you want components like this you would have to download them separately.
Once concern that has been raised is could this lead to bloating of IDS? E.g. if we're not so concerned about space might the install footprint go up? We would certainly have to be very careful about what is installed by default if we were to add components to the bundle.
Would anyone be inconvenienced if the IDS install media was no longer available on CD? If you see a problem with that please leave a comment or contact me. I am also curious as to what percentage of people download all their products electronically.
