Subject: [Neo] Database does not recover after unclean shutdown
Sent: Feb 8, 2010 6:24 AM
Hi,
while initially I was impressed by the graph traverlas speed, Im
curently testing how the database survive after unclean shutdown. To do
so, Im just running my test project as a java console app without
registering a shutdown hook and then accidently killing the JVM via
Ctrl+C or killall -9
First 3 rounds, after such resets, engine recovered lost and unfinished
transactions in a seconds and database keeps running. However, on a 4-th
round, when I terminated the database in process of full text indexing,
I got the following exception on restart and database won't start anymore.
Any ideas on how to cure similar situations - if this happened during
the testing (and happened quite quickly, on a 3-4 round of killalls),
this probably will happen in a production after a unexpected server
poweroff or so.
Thanks,
Dmitri
