Tivoli is available on Linux; very expensive, as you note.

Here's a big long list:

Here's a "technology review" apparently done at Microsoft a few years
ago.  They were trying to figure out what to add to Windows to make it
a more salable platform for this sort of thing.

Here's a somewhat aged (but still seemingly pretty relevant) article
from SunWorld:
http://sunsite.uakom.sk/sunworldonline/swol-07-1998/swol-07-scheduling.html
"Regrettably, native Unix job scheduling is pathetic."  Which I'd agree with.

Options I looked at seriously a couple years ago were:
- DollarUniverse from OrSyp
- Tidal Enterprise Scheduler

Freely available options I've seen that are *faintly* plausible include:
- Berlin Open Source Job Scheduler
<http://en.wikipedia.org/wiki/Open_Source_Job_Scheduler>
I didn't much like it.
- GnuBatch <http://www.gnu.org/software/gnubatch/>

The most successful thing I've actually deployed, thus far, has been a
set of scripts that would allow the gentle user to better manage cron.

a) Put lists of desired cron jobs into files on a central server;
b) cfengine then pulls those files out "into the field"
c) script on each server rummages thru those files, deciding which are
applicable, assembling new crontab proposal
d) dump the old crontab; load the new one
e) if old != now, then copy the old one, timestamped, into an archive directory

This gave a pretty decent "audit trail" of what was running where,
when, and was about as much as the database services group needed;
they were after regularity of things running, moreso than having
precise jobs running at precise times, possibly in relation to other
jobs.
