dealing with a large flat data files with a very big record length
- by gsp
I have a large data file that is creatd from a shell script. Next script processes it by sorting and reading several times, that takes more than 14 hours, it is not viable.
I want to replace this long running script with a program, probably in JAVA, C, or COBOl, that can run on windows or on sun solaris. I have to read a group of records everytime, sort and process and write to the output sort file and at the same time insert into db2/sql tables.
