codemine has provisions setup for multiple databases. If you recall, when you install your app it will ask you for a local directory and a shared directory. If it is setup properly it will actually ask you for the commonpath also. See cmapplicationmanager.cPathCommon.

go to the appforms.frmAppInstallDialog
and set the cFilesCommon property to a list of files that should be included and the common path box will show up the next time you install.

cFilesCommon=mydata.dbc,mydata2,dbc

goapp.install()
