  2. What is Autosave? Autosave is an EPICS extension that: Automatically saves settings in an ioc when they are changed. Loads in the saved settings on reboot of an ioc. Allows the user to determine what settings have changed since a particular file was saved.

  3. Installing Autosave • Any hardware or soft EPICS IOC can use the autosave extension • The IOC must be configured and re-compiled to use autosave • This has already been done for the HINS PLC IOCs and for the SNS LLRF IOC • Instructions are at: autosave Installation Instructions

  4. How it works • Request files list the device settings that need to be saved and restored on reboot • Whenever one of those devices is changed, an update is written to the save file automatically • A dated save file may also be written at boot time • On reboot, the contents of the most recent save file is used to restore the settings • If the user wants to know what settings may have changed since the last reboot, the asVerify utility can be used

  5. Organization • Request and save files are in the /p/iocAutosaveFiles directory under the name of the IOC hins01> ls /p/iocAutosaveFiles A0-plc hins01 hinscave smtf hins01> cd hins01 hins01> ls auto_settings.req auto_settings.sav0 save_restore.edl auto_settings.sav auto_settings.sav_080702-135343

  6. Request File is just a list of devices

  7. Save Files look like:

  9. asVerify • Add to your path: /p/epics/support/autosave/R4-10/bin/linux-x86 • To compare present settings with an existing save file: asVerify [-vrd] <autosave_file> where -v is verbose: all saved pv’s will print -r restores the named file -d (debug) increment debug level by one
