Re: Open RFIO file and SysErrors between UPDATE and READ

Hi Gerardo,

   thanks for your hints. Actually the problem is on the server side, but i've created a short while loop where, after a given sleep time, it tries to open the remote file again.

Sorry what's the difference (advatages) between TRFIOFile and TCastorFile? Since i'm writing and reading back ROOT files from CASTOR? Regards,
m
