Sometimes we have to do some 'system' calls from inside EPICS shell.

As far as I know, the normal way is to add the 'system.dbd' to the IOC's /src/app Makefile.

Is it possible to have this in oun Epics Base so that it is enabled for all our IOC's ?  The 'ReadLine' (shell history etc) is done inside the base .

You can of course make any changes you like to the code in your Base installation before you build it. We don’t have a build configuration flag that adds system.dbd to all IOCs, so the easiest way for you to achieve this would be to edit the file Base-3.15.x/src/std/softIoc/base.dbd or Base-7.0/modules/database/src/std/softIoc/base.dbd and add a line

include “system.dbd”

to the end of that file. Personally I would handle that requirement slightly differently though – our operational IOCs all build with a locally developed support module that provides common standard facilities, and I would put that kind of setting into our iocStdSoft.dbd file instead of modifying base.dbd

HTH,
