Subject Update - IOException
Date Thu, 01 Mar 2007 08:56:25 GMT
Hi,

While updating my index I have the following error :

[3/1/07 9:44:19:214 CET] 76414c82 SystemErr     R java.io.IOException:
Lock obtain timed out:

org.apache.lucene.index.IndexReader.deleteDocuments(IndexReader.java:541
)


I am using lucene 2.0,

When I execute the code below I find an entry with the specified Term
(it displays One Entry Found)
Then when I try to delete the document, I get the error I apsted above.

What I do is :
open a second index reader,
delete document
close second index reader
close main index reader, 
open new idnexreader

Can anyone help ?

Thank u very much.


  // Open second indexReader
  IndexReader mIndexReaderClone = null;
  try {
	mIndexReaderClone = IndexReader.open(mWorkingIndexDir);
  }
  catch (IOException exc) {
	exc.printStackTrace();
	throw new RegainException("Creating index reader failed", exc);
  }

Term urlTerm = new Term("url", url1);
Query query2 = new TermQuery(urlTerm2);
Document doc2;

  Hits hits2 = search(query2);
  if (hits2.length() > 0) {
	if (hits2.length() > 1) {
	  System.out.println("Duplicates Entries");
	}
	System.out.println("One Entry Found");
  }
  else {
	  System.out.println("No Entries");
  }

	  
	  
  try {
	mIndexReaderClone.deleteDocuments(urlTerm);
  } catch (IOException e) {
	e.printStackTrace();
	throw new RegainException("Deleting old entry failed", e);
  }
	  
  // Close the Clone IndexReader
try {
  mIndexReaderClone.close();
}
catch (IOException exc) {
  throw new RegainException("Closing index reader failed", exc);
}
