| FTP using Report Caster | Login/Join |
| Gold member |
Hi, I need to FTP a Report, so I am using the report caster to do the FTP. My question now is 1. If during the FTP process the file which was FTP’ed actually was a 0 byte file. In this case will the Report caster say that the FTP is successful or will it say failure? Do we have an inbuilt feature to see that the FTP’ed file is not a 0 byte file (i.e All the contents have been FTP’ed successfully) Can anyone tell me how they have made sure that the file that they have FTP’ed did not have any data loss Thanks Navaneeth WF 7.1.4 | ||

You don't specify how you are generating the file, but if it is through a fex, it will not generate a 0 byte file. That, in essence, is a "no data found" and you would see that in the RC logs. If you generate with EMPTYREPORT=ON then it would not be a 0 byte file, but it would also have no data. Part of the standard FTP process checks to see that what was sent is what was received. I don't know all the goings on of that checking process, but I think we could give IBI credit enough to have already considered this. Sometimes that's a stretch, but this is a pretty basic issue with ANY FTP process. If the file transfer was not completely successful, it would show in the RC log.

Thanks Darin, Yes report caster does throw an error if the FTP is incomplete. My other question was what happens if 100kb file is generated and after FTP we see the file size as 10kb in the new location. Does Report caster considered this as an success or an failure. I did try to replicate this condition, but was unable to do so. Will this ever happen and if it does then how do we overcome it. Regards Navaneeth | |||

My understanding is that the FTP process has built in checking and if, for whatever reason, it is isn't able to completely transfer the file, then it will throw an error. In fact, I don't believe that this situation would ever occur. If packets are lost in transmission, the process would immediately stop and you would never see the partially transmitted file because it never received the EOF. I'm not an FTP guru so someone out there is laughing at my terminology, but you get the picture. In the millions (literally) of transmissions over many years, we have never had this problem with a corrupt (or incomplete) file transfer. It either works or doesn't - never partially. But then again, that's only on our intra/extra network.
