Experimental Physics and
Industrial Control System

Changing the st.cmd file got only two records to change:

epics> dbl

bruno.martinsHost:aiExample

bruno.martinsHost:aiExample1

bruno.martinsHost:aiExample2

bruno.martinsHost:aiExample3

bruno:aSubExample

bruno.martinsHost:calc1

bruno.martinsHost:calc2

bruno.martinsHost:calc3

bruno.martinsHost:calcExample

bruno.martinsHost:calcExample1

bruno.martinsHost:calcExample2

bruno.martinsHost:calcExample3

bruno.martinsHost:compressExample

bruno:subExample

bruno.martinsHost:xxxExample

I suspected the files user.substitutions and userHost.substitutions were the responsibles, changed "bruno.martinsHost" and "bruno.martins" to "bruno", ran st.cmd again, same results.

Only when I recompiled all changes took effect:

epics> dbl

bruno:ai1

bruno:ai2

bruno:ai3

bruno:aiExample

bruno:aiExample1

bruno:aiExample2

bruno:aiExample3

bruno:aSubExample

bruno:calc1

bruno:calc2

bruno:calc3

bruno:calcExample

bruno:calcExample1

bruno:calcExample2

bruno:calcExample3

bruno:compressExample

bruno:subExample

bruno:xxxExample

Is this recompilation really necessary? The way I see, the st.cmd file is a script that loads these *.substitutions files and parse them dinamically, but seems not quite like that.

It is, and you are welcome.

As otehr have noted, dot ('.') is not allowed in record names.

However, your db file should have been rejected when loading, and not when
trying to find the record. So this is actually a bug in EPICS base.
