- Create the $IOC_DATA directory for your cpu and iocs as follows:
- cd $IOC_DAT
- Create the $EPICS_IOCS cpu and ioc boot directories
- cd $EPICS_IOCS
- mkdir cpu-<area>-<subsystem-prefix><2-digit#>
- mkdir sioc-<area>-<subsystem-prefix><2-digit#>
- Setup cpu directory files
- cd cpu-<area>-<subsystem-prefix><2-digit#>
- Setup relative symbolic links to the common startup script and EPICS version:.
- ln -s ../common/st.cmd.linuxRT.cpu startup.cmd
- ln -s ../common/bin/<epics base version> epicsSpecificRelease
- Generate the file kernel-module.cmd. This file load kernels modules and drivers: kernel-modules.cmd
- for examples click here.
- Setup ioc directory files
- cd sioc-<area>-<subsystem-prefix><2-digit#>
- copy the ioc startup.cmd script from $EPICS_IOCS/template
- for linuxRT running iocsh: cp ../template/startup.cmd.linuxRT startup.cmd
- for linuxRT running cexp: cp ../template/startup.cmd.linuxRT.cexp startup.cmd
- edit startup.cmd
- replace <ioc> with your ioc name and for cexp replace <facility>
- change path of the EPICS_IOC_APP in your st,cmd file is in a non-standard location.
- cp ../template/screenrc screenrc
- edit screenrc and replace <ioc> with your ioc name.
- Setup a relative symbolic link to the TOP of the IOC Application release.
- ln -s ../../iocTop/<app>/<version> iocSpecificRelease
- Modify $EPICS_IOCS/screeniocs – Please note that this is a symbolic link to this CVSed file:
- verify that the file in use has not been modified without being committed.
- cd $EPICS_IOCS/facility

If you don't get a response, you can either add the changes to CVS in addition to yours or just add yours.
- check out screeniocs from CVS into your work area
- cd
- cd <work>
cvs co -d epics/iocCommon/All/<facility> , where facility is Dev,Prod,facet,acctest - cd epics/iocCommon/All/<facility>/screeniocs
- edit screeniocs
- add line for cpu
format: cpu-<area>-<subsystem-prefix><2-digit #> <ts> <ts port #t> <screen host> [ # comment] - add line for each ioc
format: sioc-<area>-<subsystem prefix><2-digit #> cpu-<area>-<subsystem-prefix><2-digit #> <account> [ # comment] - The "comment" field in screeeniocs is optional and must be precede but "#".
- commit your changes of changes of screeniocs to the code management system (CVS) CVS as follows:
- cvs commit -m "added cpu and ioc blah" screeniocs
- update the screeniocs file in use
- cd $EPICS_IOCS/All/<facility>
- rm -f screeniocs
