the crontab are shell programs that read sth. from oracle and write results to a file named

Your starting point should be nfs directories.

Can you create/write on these nfs directories with problems?

If no crontab scripts will have same problem writing to nfs directories.

how you have mounte nfs directories. Post the options.

What happens when you run these jobs manually (ie, wuthout using cron?) Remember that cron never logs in...it runs on behalf of the owner of the cron job (ie, oracle) but does NOT inherit any of the standard environment seen with an interactive login. So if running manually works OK, you are likely seeing problems with unset enviroment values.

my englist is poor!sorry

1.the environment is ok.
2.in the nfs directory,i can mv files to other directories or change the file name.
3.but when i use vi to create a new file,it is very slowly,that is,i can't use
"wq" to exit.
4.execute the job manually:sometimes ok,sometime failed.

i think may be:

1.the network performance
2.the server performance
