Error in script when use cron

Hi
One of our developers that use oracle, try to run one script, and by session runs ok, but when he try to run by cron or at, it doesn’t run properly and this appear

11:21:28 SQL> BEGIN
11:21:28 2 SYS.DBMS_STATS.GATHER_INDEX_STATS (

11:21:28 5 ,Degree => NULL
11:21:28 6 ,No_Invalidate => FALSE);
11:21:28 7 END;
11:21:28 8 /
BEGIN

He did some research and find this

“The batch is scheduled by crontab. Due to feature of 'at', the job is executed
in a separate invocation of the shell, i.e., '/usr/bin/sh'. By default, the
ulimit set by sh shell is 4194303, which means not unlimited (4194303 * 512 bytes
of block size = 2Gb). No matter what shell is being used, the 'at' always set
that limit to 2Gb. The error then occurs because some operation accessed the data
in the datafile beyond 2GB.
Fix
~~~~
If you need to use the 'at', then it is recommended to edit file
'/var/adm/cron/.proto' and modify the string 'ulimit $l' for 'ulimit unlimited'.
This garantees that the value 4194303 will no longer be used by the 'at'. “

I saw my file .proto but I had ulimit $l instead of 1.

What does .proto do ?

Re: Error in script when use cron

The default .proto file from an 11.00 system is:

# cat /var/adm/cron/.proto
# @(#) $Revision: 27.1 $
cd $d
ulimit $l
umask $m
$<

look more in man pages of proto....

man 4 proto

-USA..
Good Luck..

Re: Error in script when use cron

AT command, in order to simulate the current environment while executing the job, adds all the environment settings and copies the contents of the /var/adm/cron/.proto file to the job file, except by replacing special variables with values.

From the man page of proto

$l Replaced by the current file size
limit (see ulimit(2))
