Hi James,
Thanks for your response. I'm using the old archiver and what I
would like to do
is to use my new machine to serve the copied/archived data, so it
does appear
that we have/had a similar problem. I don't, at the moment, need
the archive
engine. I did successfully build the installation on the 64-bit
machine.
If I'm not mistaken, ArchiveExport does not require the data server
to be running,
but it does require that the index files be correct. If that is
true, then I'm not even
at the point of concern for the server, but would like to rebuild
the indices. I've
tried update_indices.pl, but get errors with the archiveconfig.pm
file
(not a HASH reference ...). Am I correct in deducing that I need to
recreate my
index files? If so, any guidance on doing so would be welcome; I
must be missing
something when I read the manual.
Thanks,
Pierrick

Is this the old channel archiver or the CSS based RDB archiver?
I did the same thing with the channel archiver and it took a while
to resolve. The heart of the trouble is that the cgi data server
(ArchiveDataServer.cgi for the channel archiver) was unable to run
due to a number of issues. The archive viewer couldn't see the
data because ArchiveDataServer.cgi couldn't start. The final
solution for me was to recompile the archiver from scratch on the
64 bit machine and use the xml index files and data from the 32
bit machine. I had to have a lot of help doing this, so I won't
be very helpful on how to do that I'm afraid. However, my goal
was to get the archiver running as well as being able to see the
data. Perhaps as long as you can get the archive data server
working you don't need to do this. I would suggest transferring
ArchiveDataServer.cgi from the old machine to the new machine with
all of its libraries (the 32 bit ones) as a starting point.
The channel archiver manual may help. It has a section on testing
this server. It is woefully out of date and quite terse, but it
can at least show you where to place the cgi server and how to
test it: http://www.slac.stanford.edu/grp/lcls/controls/global/sw/epics/extensions/ChannelArchiver/manual.pdf.
If you are using the RDB archiver, I'm afraid I can't help.
Hope that at least gives you a starting place!

Hi,
I copied some archived data from a 32-bit machine to a
64-bit machine. I'm not able
to read the data. If I do an ArchiveExport I see only a
very small number of entries.
I'm guessing that I need to regenerate the indices, but I've
not been successful in doing
so; perhaps I'm not understanding the manual.
Please help. I've wasted an inordinate amount of time.
Thanks,
Pierrick
