James Rowland from Diamond recently did a poll and has the most current list of archiving solutions that are used with EPICS. I think he will talk about it at the upcoming EPICS Collaboration Meeting in two weeks. My first order answer would be: There's the Channel Archiver: old, stable, fast, very widely used, but not based on a RDB. There are several other archiving solutions, some of which use a RDB for storage, others don't. Different ages, different languages, different file formats or RDB systems for storage. Their common feature: they are all used at one lab only, two labs maximum. CSS databrowser support is available for the Channel Archiver, and for the Oracle-based archiver at SNS. (The latter might not be part of the DESY CSS.) There is experimental support for HyperArchiver (Channel Archiver writing into Hypertable). While RDB-based archiving solutions have a tendency to be slower (as well in writing an archive as retrieving from it), I don't see an issue here for your system (unless your 10K channels are updating every second or faster). Hope this helps, Ralph On 28.09.2010 10:23, Dirk Martin wrote: Hallo,
