Re: is there an EPICS module to makePvToArchiveFromDbInfo() ?

Hi Victor,

In case you are using the archiver appliance and channel finder/recsync, you can accomplish this via the channel finder AA processor - https://github.com/ChannelFinder/ChannelFinderService/blob/master/src/main/resources/application.properties#L96

Best,

Tynan

Hi Victor,

If you use a recent version of base, you can list tags on the IOC shell and write them to a file:

epics> dbli *archive*
ST99:Det:IOC_SADet3:Status info(archive, "Monitor, 00:00:01, VAL")
ST99:Det:IOC_SADet3:StatCtrl info(archive, "Monitor, 00:00:01, VAL")
ST99:Det:IOC_SIDet3:STATUS info(archive, "Monitor, 00:00:01, VAL")
ST99:Det:IOC_SIDet3:STATCTRL info(archive, "Monitor, 00:00:01, VAL")
epics>
epics> dbli *archive* > /tmp/archive_list.txt

cat /tmp/archive_list.txt
ST99:Det:IOC_SADet3:Status info(archive, "Monitor, 00:00:01, VAL")
ST99:Det:IOC_SADet3:StatCtrl info(archive, "Monitor, 00:00:01, VAL")
ST99:Det:IOC_SIDet3:STATUS info(archive, "Monitor, 00:00:01, VAL")
ST99:Det:IOC_SIDet3:STATCTRL info(archive, "Monitor, 00:00:01, VAL")

Then you can parse that list and generate an archive configuration. Or, modify an archiver to be able to read that format.

We use a Python script to parse the database files, but if we were starting today I'd probably use the above method as the first step in extracting the info tags.

Cheers,
Matt

Hi Victor -

There is one that we have used at ESS that might serve your purpose:

https://urldefense.us/v2/url?u=https-3A__gitlab.esss.lu.se_icshwi_iocmetadata&d=DwIGaQ&c=v4IIwRuZAmwupIjowmMWUmLasxPEgYsgNI-O7C4ViYc&r=aEDRFW1J1RKf3L4Vy5iLgaY2FJpZ2TV1XDtc_tKxW00&m=vNISIrtmTSvaQHTNeWDl1p15L43in4-yA1-44ChtrvumzGayCjG4ekJITH08uJbN&s=CH3zpoO636P0uNZGzJnegnwLIRfFkNbkML82l2Cap0E&e=

Note that it uses EPICS 7 NT types. There is pretty good documentation in the README file in the repository.

Cheers,

Simon

Hi all,


is there an EPICS module to, in the same way as `makeAutosaveFileFromDbInfo()` works, generate (at IOC boot, so macro are resolved) a file with a list of PV names to archive from the information provided in the record `info()` field ?


```epics
record(ai, "MyPv") {
info(archive, "YES")
}
```


This would be a nice tool to then copy/past all the pv list files to archive in the archiver.


Thanks for the answer,


Cheers,
