EPICS V4: Standard Support September 30 2005


Overview

For V4 dbCommon.dbd and RecordCommon.dbd replace the V3 dbCommon.dbd. dbCommon.dbd defines widely used definitions and RecordCommon.dbd defines the fields that are common to all record types.


This document requires that the reader be familiar with:

  1. V3 iocCore
  2. V4 DBD Statement Syntax
  3. V4 DB Record Instance Syntax

dbCommon

Channel/Database Access Support

Data Structures

    struct(MonitorLinkData) {
        field(pvname,string) { link}
        field(process,boolean) // process this record when monitor occurs
        field(inheritSeverity,boolean) 
    }
    struct(InputLinkData) {
        field(pvname,string) { link}
        field(process,boolean)
        field(wait,boolean)
        field(timeout,float64)
        field(block,boolean)
        field(inheritSeverity,boolean)
    }

        field(processLink,array(RecordCommonProcessLink[])) {
            special(yes)
        }
    }

Although it has many fewer fields, RecordCommon.dbd is a complete replacement for the V3 dbCommon. The following V3 fields are no longer needed:

  • private fields - Private fields will truly be privaye to the implementation
  • previous value fields - All puts to database fields will be posted. The layer above will decide if clients should be notified of changes.
