EPICS archiving with MYA
From GlueXWiki
- Accelerator division at Jefferson Lab developed and currently maintains a MySQL-based EPICS archiving system called MYA. Hall D controls group will use this system to archive the EPICS variables.
- The accelerator division is also developing a Backup/Restore framework based on the MYA archiver which should allow us to tag sets of values for Hall D EPICS in MYA PVs and restore these values from the archived values.
- MYA has a well document API that should allow the offline analysis software to retrieve the archive values and store them into a conditions database.
- There are command-line tools that allow to work with MYA archiver, for instance to get values for particular variable in a specific time-span.
- Currently installed on gluon01 and ops-machines only. It will be available on the gluon-cluster.
- MYA also has a graphical tool MYAViewer to display variable being archived in MYA
- Currently no interface is available between MA and CSS BOY, but we can pop up MYAViewer.
- Currently installed on gluon01 and ops-machines only. It will be available on the gluon-cluster.
- So far requested MYA archiving for some BCAL temperature, BCAM VME fan-tray parameters and FCAL dark room parameters:
- The corresponding MYA groups so far are HD_BCAL_TEMPS,HD_FCAL_ROOM, HD_VME .
- More groups and PVs ill be added.
