1. Stanford Linear Accelerator Center Epics.db to Oracle RDB Organizing site-wide Epics data Ron Chestnut – SNS November 2000

2. Three steps from.db to Oracle Generate a database report Import the report with Sqlload Parse the names to get individual fields Used at SLAC for compatibility with legacy control system wildcarding capabilities

3. Generating the report (1) bic_template file./bic_bxbcm.db { {STN=HB60,BIT3_CARD=0} {STN=LB60,BIT3_CARD=1} } file./bic_dcct.db { {STN=HB60}{STN=LB60} } etc.

4. Generating the report (2) bic_report script rm bic.all_pv dbLoadTemplate bic_template | dbreport OUT.INP.35 DESC.20 | sort > bic.all_pv

5. Import the data with SQLLOAD Script sqlloader acct/pwd control=pvload.ctl Control file options(skip=2) load data infile ‘bic.all_pv’ append into table pvlist when pv_type != “TYPE “ (pv_type position(1:15) char, pvnam position(16:45) char)

6. Parse the names into fields pvnam = PB60:DCCT:LIFETIME fld1 = PB60 fld2 = DCCT fld3 = LIFETIME nfld = 3

7. End up with nice table SQL>desc pvlist name type ========================= PV_TYPEchar(15) PVNAMchar(30) PV_INOUTchar(35) PV_DESCchar(20) FLD1char(15) …. FLD6char(15) NFLDnumber(1) pv_last_fieldchar(15) SQL> select count(*) from pvlist; COUNT(*) ---------------- 16932

8. Current Uses at SLAC Support wildcarded history source files Generate filtered and sorted reports with simple SQL Provide a uniform way to find PV names Reduce maintenance load
