Removing a write.lock file
Hi,
I'm currently indexing allowing multiple access , I find that a
write.lock file has got created.
I know this is to prevent multiple writers, but now how do I
continue.??I do not want to reindex as I work on a very large database
and it takes a real long time How do I remove this lock file ??

Thanx 4 ur help,
Suneetha.
RE: Removing a write.lock file [ In reply to ]
Hi,
The write.lock file won't be there if you close the index using a lock
mechanism. I use my own RWLock to access the index dir and unlock it after I
close the index. Basically, the access to the index is synchronized. I have
never had any problems with this approach.

well suneetha,

before I write to the index I check whether a write.lock file exists! If
it does I delete it before opening the index. It works fine
for me.

I don't think it is a good approach to delete the write.lock file by hand.
It is there for a reason. You may want to dig into some of the older
dialogs/e-mails on this topic.

RE: Removing a write.lock file [ In reply to ]
Sorry, but I would say the same thing. I don't think you are supposed do it
even programmatically. It is a lock internal to lucene.

RE: Removing a write.lock file [ In reply to ]
If your not letting lucene remove the write.lock file, and doing it with
your own code, that just screams out to me to be a very bad thing to do.

Unless of course you want things to get corrupted.

Maybe it has worked for you so far, out of luck, but I'm sure its not the
way you are supposed to be doing things.

RE: Removing a write.lock file [ In reply to ]
Since I am far from a lucene expert, I would suggest searching the archive
for write.lock, I'm sure this has been discussed before.

My belief is that when you call the close method to close your index writer,
it removes the write.lock file.

Someone please verify/correct me if I'm wrong.
