RE: FW: Question Regarding RCS

[Hemadri, Satish]

Hi,

When I am trying to check-in SAS dataset which is of more than 2 gigs, I am getting the below error.

ci: dt_lab_safe_tst.sas7bdat: Value too large for defined data type

Thanks & Regards,

I can't recall that I have actually tried it with large files.  In

Unix-speak large files means files larger than the 2G 32-bit signed

long integer limit.  But I also don't recall any specific limitation

in the file format that would prevent it.  I will say that I think it

should work with the addition that if it is shown not to actually work

in practice then I think that would be a bug to be fixed.  Because I

think it should work.

The GNU Project doesn't generally make binary versions available.  The

GNU Project is all about the source code.  As source there isn't any

specific 32, 64 or even a 36 bit version.  It doesn't get frozen into

a specific binary executable type until it is compiled.  The GNU RCS

source can be compiled into a 64-bit executable just fine.  Also,

most architectures support a 32-bit executable with large file support

where the 32-bit executable can access large files (>2G).  I routinely

use the 64-bit GNU rcs distributed with Debian on amd64 machines.

Have you actually tried GNU rcs with a large file and found that it

has not worked yet?  If so please provide the error message.  But it

sounds like you are just asking it if should work or not.

As Aaron noted in the message you quoted there hasn't been any recent

updates to RCS because for the most part no updates have been needed.

RCS is a very mature program and has reached a point in its lifecycle

where stability is requied and no new features are being added to it.

Almost every operating system software distribution provides rcs in

its software repository.  It is generally prevalent everywhere.

In order to get more help please reply back to the mailing list with

more information about your environment.  You say you are using a Unix

server but didn't say what operating system and architecture you are

using there.  It could be any of many available.  The OS itself might

not even support large files.  At the least we would need to know some

basic information about your system.

  $ uname -a

Also include any error messages that you are seeing from the tools.
