573.0. "SORT of large file in Digital Unix !" by DEKVC::DOOGYUPARK () Sun May 18 1997 04:33
Hi,
I had a test of sorting with Digital Unix V3.2E-2 , MFCobol V3.2B as follow.
- record size : 800 Bytes
- total number of record : 1,300,000 (1Gbytes in size)
- It takes 25 minutes and it consumes about 2Gbytes temporary area.
But,with 1400000 records,the size of temporary file grows continously up to
more than 9 Gbyte and sorting is never ended , so i interrupted the sorting
task.
I.e. in 1300000 records,it works but in 1400000 records,it doesn't works.
And i tried with SORT statement and MFSORT tool,but got the same result in
both trial.
Is it a limitation or a problem in sort of MFCobol or in UNIX ??
Thanks a lots,
dg.

| 573.1 | sort size problem - fix in test | PACKED::KIDS::NESCHKE | | Mon May 19 1997 10:07 | 10 |
| Micro Focus has been working a fix for a sort problem (of files greater
than 1GB) that's planned for
the next major release. I have a pre-release copy of a compiler for
testing. If possible, I'd like to discuss (off-line) a way to have
this fix tested in your environment.
As I understand it, the problem occurred across a set of platforms
running the Micro Focus product.

| 573.2 | May want to consider Syncsort? | GRANPA::EBILLITER | | Wed May 28 1997 07:03 | 10 |
| Hello,
I suggest you look at using Syncsort for the UNIX sort instead of a
native sort. Syncsort is known for better performance on all
platforms. They have tested on a VLM system and announced really
terrific results! Also they work with Micro Focus COBOL. If you are
interested we can try to find the Korean Syncsort contact, so you can
explore this with the customer.

Now,i found out a workaround and i will try with next release of
MFCobol.
We are waiting for the test version of it.
