[opencms-dev] RES: RES: Search index locked (maybe)

[Deiverson Silveira]

Oh =|

I think this problem in Lucene:
My program crashed and now I get a "Lock obtain timed out." error. Where is
the lock and how can i delete it?

When using FSDirectory, Lock files are kept in the directory specified by
the "org.apache.lucene.lockdir" system property if it is set, or by default
in the directory specified by the "java.io.tmpdir" system property (on Unix
boxes this is usually "/var/tmp" or "/tmp").

If for some strange reason "java.io.tmpdir" is not set, then the directory
path you specified to create your index is used.

Lock files have names that start with "lucene-" followed by an MD5 hash of
the index directory path.

If you are certain that a lock file is not in use, you can delete it
manually. You should also look at the methods
"IndexReader.isLocked<http://lucene.apache.org/java/docs/api/org/apache/lucene/index/IndexReader.html#isLocked(org.apache.lucene.store.Directory)>"
and "IndexReader.unlock<http://lucene.apache.org/java/docs/api/org/apache/lucene/index/IndexReader.html#unlock(org.apache.lucene.store.Directory)>"
if you are interested in writing recovery code that can remove locks
automatically.
