By the way, why
Code:
status=`db2 -x select status from TABLE_X where end_date = select max(end_date) from TABLE_X`

this script above doesn't work when executed by cron?
It doesn't work because cron doesn't know how to set up your environment like your shell does. When you log in, your shell initializes your environment with settings that allow your database commands to be found without specifying absolute pathnames for the database utilities and includes settings specifying what database to use and what access codes are needed to access that database. You have to make the script you run with cron make that same environment information available to the shell that is being run by cron.

make_combined_log2

make_combined_log.pl(1) 				      General Commands Manual					   make_combined_log.pl(1)

NAME

       make_combined_log.pl - make combined logfile from SQL database

SYNOPSIS

       make_combined_log.pl <days> <virtual host>

DESCRIPTION

       This perl script extracts the httpd access data from a MySQL database and formats it properly for parsing by 3rd-party log analysis tools.

       The  script  is	intended  to  be run out by cron. Its commandline arguments tell it how many days' worth of access records to extract, and
       which virtual_host you are interested in (because many people log several virthosts to one MySQL db.) This permits you  to  run	it  daily,
       weekly, every 9 days -- whatever you decide.

NOTE

       By  "days"  I  mean "chunks of 24 hours prior to the moment this script is run." So if you run it at 4:34 p.m. on the 12th, it will go back
       through 4:34 p.m. on the 11th.

KNOWN ISSUES

       Because GET and POST are not discriminated in the MySQL log, we'll just assume that all requests are  GETs.  This  should  have	negligible
       effect  on  any analysis software. This could be remedied IF you stored the full HTTP request in your database instead of just the URI, but
       that's going to cost you a LOT of space really quickly...

       Because this is somewhat of a quick hack it doesn't do the most robust error checking in the world. Run it by hand to  confirm  your  usage
       before putting it in crontab.
