A common way of handling this is with:
	template/substitution files so that each IOC has its own .db file
or

 one .db file loaded by all IOCs with different macro definitions in

the dbLoadRecords commands.

What should I do if I have multiple iocs under the same top

directory, and they all use a common .db file? Is there a similar Db

directory to put them in that is not specific to one application?

Thank you,
Patrick

You can put entries in the xxxApp/Db/Makefile, and then make will

copy the .db files to the TOP/db directory. But you don't have to

do this if you don't want to, you can have the IOC directly load

the .db files out of the xxxApp/Db directory. The latter is what I

do, because I deploy EPICS on sites where they don't have a build

system, and so can't run make. So we just use the .db files in the

Db/ directory.

I'm sorry, I don't quite follow, where do I put the .db files that

will

be loaded by the ioc? Do I have to put something in one of the

Makefiles?

Does makeBaseApp -t ioc normally create a db folder in the top
directory, or does that get made by the user?

Neither; directories such bin, db, dbd, doc, html, include, and

lib will get

created at build time when make has something that needs to be

installed in

the relevant directory. Note that if you do a 'make distclean' at

the top

level, these directories *and their contents* will be deleted, so

it is a bad

idea to add files to them manually as they might not have a very

long life.
