Hi:

There should be a file similar to
 /tmp/archserver.log
that logs the request which the network data server saw.

If you exercise that same request with ArchiveDataClient.pl,
you might see a better error message.

Right now I don't know what the problem is.
The archive data files could be damaged,
but that shouldn't be the case with the
demo data.

Are the data files accessible?
Maybe you just made the index file accessible,
but not the data files?

Hi Kay,

Thank you for your suggestion - it worked.


We have one more question. right now by doing:


[sysuser@sc XMLRPCServer]$ ./ArchiveDataClient.pl -u http:// sc.starp.bnl.gov/archive/cgi/ArchiveDataServer.cgi -k 1 -l
Channels:
Channel BoolPV, 03/05/2004 18:53:56.767577600 - 03/05/2004 18:58:51.901960000 Channel DTL_HPRF:Tnk1:T, 03/01/2004 17:28:00.035262000 - 03/29/2004 13:01:00.230310000 Channel DTL_HPRF:Tnk2:T, 03/01/2004 17:28:00.035262000 - 03/29/2004 13:00:00.031041000 Channel DTL_HPRF:Tnk3:T, 03/01/2004 17:27:59.985282000 - 03/29/2004 13:01:00.280299000 ...


we do see all channels inside index file but once we try to run it with ArchiveViewer and plot it gives the error message :

java.lang.Exception: Couldn't execute the archiver.values request java.io.IOException: org.xml.sax.SAXParseException: expected Element

and in console: Fatal error parsing XML: org.xml.sax.SAXParseException: expected Element

Any idea?

Bill && Yura

Thanks

Hi:

Well, I assume that
'/home/sysuser/epics/extensions/src/ChannelArchiver/DemoData/index'
is actually an existing path & filename that you configured.

The error message indicates that your web server &
ArchiveDataServer are also OK, otherwise
you'd never get as far as that error message.

The web server runs your copy of the network data server
as "nobody" or a similar low-privilege user.
So the next thing to check would be that
/home/sysuser/epics/extensions/src/ChannelArchiver/DemoData/*
and all the directories in the path to ... DemoData
have 'r-x' access for "nobody" or whoever's configured
in your web server to run CGI code.

Hi All,


We installed epics 3.14.8 with ChannelArchiver (compilled without
any problems).
The box is Scientific Linux SL release 3.0.5 (SL) with Apache/
2.0.46.  We have a small problem with ArchiveDataServer -
it's up and running  but if we try to check the index file in the
DemoData we run into the error message :


[sysuser@sc ChannelArchiver]$ ArchiveDataClient.pl -u http:// sc.starp.bnl.gov/archive/cgi/ArchiveDataServer.cgi -k 1 -m Ex Channels: Fault returned from XML RPC Server, fault code -601: Cannot open index '/home/sysuser/epics/extensions/src/ChannelArchiver/DemoData/ index'

Any suggestions?


Thanks, Bill Waggoner && Yura Gorbunov
