Re: Transfer a large number of sequential file from mainframe to redhat linux V6.5

What about NFS? More general: What is the work flow? Usually the transfer of many big files is not the goal itself. Maybe the files should be opened and read byt some application. NFS (of DRF/SMB) would save the time by simply avoiding the transfer before the applications start reading data.

Hello, another option would be to add the line MODE C before the put or mput line in your FTP'S. This does compression only during the FTP. This could speed up the FTP's. -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of

Hi John Could you give us a sample of the ftp job or the rexx? Thanks a lot ! Jason Cai >>​My first though is to "tune" your network. I'm assuming you are talking >>from z/OS to Linux via TCPIP over ethernet. ​From what little I know, most seem to use an MTU of 1500. You might get better

Hi We could move our datasets to a same volume and convert the volume to a cckd image using Hercules utilies after we transfer the cckd image to linux,how will the cckd image be used by linux? Thanks a lot! Best Regards Jason Cai >A suggestion...Could be better or not... You could

A suggestion...Could be better or not... You could try... Convert your volume to a cckd image using Hercules utilies. Once they are converted, you will be take advantage of compression and time to this transfer. I did same thing some thing, with success. Btw there is one a problem, you need to

I know ftp has done a lot of work in performance. I don't know about xcom. There were some nice presentations on FTP performance. Rob Schramm On Wed, Oct 11, 2017, 10:43 PM ibmm...@foxmail.com wrote: > Hi all > > We will transfer a large number of sequential file from

Transfer a large number of sequential file from mainframe to redhat linux V6.5

Hi all We will transfer a large number of sequential file from mainframe to redhat linux V6.5. Normally we use FTP or XCOM to transfer file. Could you tell us wherther there is the best way to transfer file from mainframe to redhat linux V6.5 for saving the transfer's time ? for
