RDB Issues at SLAC Archiver Store General EPICS Support

Oracle Archiver data store Oracle 9 based Used partitioning feature This year’s bill $30,000 (for this feature) New collaboration archiver has now fixed the problems we solved with Oracle New collaboration archiver promises much more functionality soon; strong team at work here. Oracle is MUCH slower at retrieval

Oracle vs. File-based Retrieval Retrieval testOracle (with partitioning) New file-based 86,000 points of scalar data 48 seconds5-6 seconds 4050 points of length-4 array 12 seconds< 1 second 4050 points of length 3072 array 56 seconds11 seconds

Why is Oracle so bad? Heavily indexed Partitioning improved performance x2 Simple tables Data not organized well with respect to minimizing number of disk reads in Oracle. Oracle archiver with few PVs works much faster (fewer disk reads).

RDB supporting EPICS Very hot area of interest Many talks in last several EPICS meetings Split between “as-is” (reactive) and “generating” (proactive) RDB Collaborations (or collaboration wishes) are strong Issues include scope, data capture, tools - pretty much everything.

Recent Work (Which I remember) Diamond (big plans) SNS Argonne BESSY DESY TJNAF SPEAR

EPICS Schema contains (Diamond Talk) Domain, Subdomain, Technical Area, Component Crate Device IOC DBD DBGroups DB File DB file Templates Slot Carrier & IP Cards Connection Between the Cards & the Device

SLAC’s long-standing idea “UPV” Universal PV database –Generation type –Support many subsystems Alarm handler configs Channel watcher configs Archiver configs EPICS.db and.template files –NOT device oriented –NOT including cabling, maintenance, etc.

SLAC prototyping (J. Rock) Oracle developer ER diagrams Scripts to expand EPICS db templates Experimentation with tools for maintenance –Mass modifications –Grouped modifications –Single modifications Experimentation with scripts for generating subsystem configs (and.db)

SPEAR (S. Allison) PV information gathered upon reboot (triggered from IOC) Database is NOT Oracle TCP server on host for transfer Does data restore too Database User Interface is php ODBC interface for Excel export

Tools Pre-Java oracle tools (webforms, etc.) JDeveloper JDBC PHP, Apache servers Excel interfaces

Biggest problem with RDB Projects always start WAY TOO LATE with the RDB support part The bigger the planned scope (Include maintenance? Include wiring? Include fieldbus connections?) the more important an early start is. Can the SNS/Argonne/?? Collaboration help us “legacy installations” catch up?
