Not as far as I know. APS DAQ software does not use startPVAServer. We have a wrapper
singleton class (https://git.aps.anl.gov/C2/daq/modules/daq-base/-/blob/master/src/pva/DaqPvaServer.cpp?ref_type=heads) which
starts PVA server whenever the first instantiated plugin acquires singleton instance and adds its PVA record.

Other than adding it to the exampleApp/src/Makefile the only place we've ever published a mention of that DBD file is the release notes from pvAccessCPP, and those notes don't explain what it does. It is mentioned in the " Adding QSRV to your IOC" section of the QSRV1 documentation. https://urldefense.us/v3/__https://epics-base.github.io/pva2pva/__;!!G_uCfscf7eWS!bU9CfhLz65xj3YZ2XjTgqbXdg_BbBW1UXuUqys0TV6qj6ej0oiRzquBkRrbsTDLBKFavDDj3XCOcvOso-RVpt9RPlQ$ > I don't think our DAQ servers are including it so it may be that pvDatabase also starts the server independently? > > - Andrew > > -- > > Complexity comes for free, Simplicity you have to work for. > |
