From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 4.0; Q312461) Description of problem: compress appears to stop compressing after 2GB for large files. The file size started at 4GB, but when uncompressing it only comes up to about 2GB. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Use oracle export and import facility. 2. Set oracle environment 3. compress < file.dmp > file.dmp.Z & 4. exp username/password file=file.dmp full=y 5. uncompress < file.dmp.Z > file.dmp & 6. imp username/password file=file.dmp show=yes Actual Results: After 4: Export terminated successfully without warnings After 6: IMP-0009 - Abnormal end of export file Import terminated successfully with warnings (which is oracle-sleak for 'it failed'! Expected Results: Import terminated successfully Additional info: doing a 'strings' on the export file shows that no further data was stored after the 2GB limit. I suspect that this is a similar bug to that in the 'find' command that comes with the RedHat 7.2 release (now fixed)
A workaround, of course, is to use gzip, which appears to be ok, although I haven't done the full tests yet. However I guess that compres, being a 'proper' utility, should work properly.
Happens to me,too... working on a fix.
Fixed in latest ncompress.
