+# 3. Use of substitution files to generate EPICS Databases
+
+Date: 2023-11-30
+
+## Status
+
+Accepted
+
+## Context
+
+There are two proposals for how EPICS Databases should be generated:
+
+1. At IOC startup `ibek` should generate a substitution file that describes the
+   required Databases.
+
+   The IOC instance yaml combined with the definitions from support module yaml
+   controls what the generated substitution file will look like.
+
+   `ibek` will then execute `msi` to generate the Databases from the
+   substitution file.
+
+2. The dbLoadRecord calls in the startup script will pass all macro substitutions
+   in-line. Removing the need for a substitution file.
+
+## Decision
+
+Proposal 1 is accepted.
+
+Some template files such as those in the `pmac` support module use the
+following pattern:
+
+```
+substitute "P=$(PMAC):, M=CS$(CS):M1, ADDR=1, DESC=CS Motor A"
+include "pmacDirectMotor.template"
+```
+
+This pattern is supported by msi but not by the EPICS dbLoadRecord command which
+does not recognise the `substitute` command.
+
+## Consequences
+
+An extra file `ioc.subst` is seen in the runtime directory. In reality this
+is easier to read than a full Database file. So can be useful for debugging.
+
+Finally those developers who are unable to use `ibek yaml` for some reason can
+supply their own substitution file and ibek will expand it at runtime. This is
+much more compact that supplying a full Database file and important due to the
+1MB limit on K8S ConfigMaps.
