Subject [jira] Commented: (DIRSERVER-685) Modification on an entry should always be flushed to the disk

Jörg Henne commented on DIRSERVER-685:
--------------------------------------

Great to see you have a look at this problem. I've noticed that upon unclean shutdowns, updates
are usually lost. A quick glance at the code indicated that the JDBM commit was only called
during clean shutdown, so this issue was already on my list. Since even if there are not formal
transactions, DS should try to ensure durability of updates. This means committing after each
update by default, despite the performance hit it will bring about.

> The JDBM backend, AFAIK, only update its cache, and a thread flush those caches periodicaly.
However, I may be wrong (and I hope to be wrong :)
