Problem in writing more record to berkeleyDB

i am using berkeley DB JE 4.1.10
i have use the secondary database concept and I want to insert 10,00,000 rows to the database .

i am getting following error

开发者_高级运维Exception in thread "main" com.sleepycat.je.EnvironmentFailureException: (JE 4.1.10) JAVA_ERROR: Java Error occurred, recovery may not be possible.

i have set the following parameter for environment and database


Environment env=null;
Database primarydb=null;
SecondaryDatabase secondarydb=null;
@SuppressWarnings("rawtypes")
TupleBinding mybinding=null;
String firstdb="CDRFirstDatabase";
String seconddb = "CDRSecondDatabase";

public void setupenvironment()
{
try
{
// Environment

File dbpath = new File("W:/dhananjay/workspace/BDB-SecondaryDatabase(JEAPI)-SmaxCDR/src/DB1");
EnvironmentConfig envconfig = new EnvironmentConfig();
envconfig.setAllowCreate(true);
envconfig.setTransactional(true);
env = new Environment(dbpath,envconfig);

// Primary Database

DatabaseConfig dbconfig = new DatabaseConfig();
dbconfig.setAllowCreate(true);
dbconfig.setTransactional(true);
dbconfig.setSortedDuplicates(false);

primarydb = env.openDatabase(null, firstdb, dbconfig);

// Secondary Database

SecondaryConfig secondarydbconfig = new SecondaryConfig();
secondarydbconfig.setAllowCreate(true);
secondarydbconfig.setTransactional(true);
secondarydbconfig.setSortedDuplicates(true);

// Create Key for secondary DB

mybinding = new MyTupleBinding();
SecondaryKey keycreator = new SecondaryKey(mybinding);
secondarydbconfig.setKeyCreator(keycreator);
secondarydb = env.openSecondaryDatabase(null, seconddb, primarydb, secondarydbconfig);

}
catch(Exception e)
{
System.out.println("Error----->"+e);
}
}

i am using following code to insert the data into database

DBEnvironment dbenv = new DBEnvironment();
DatabaseEntry theKey = new DatabaseEntry();
DatabaseEntry theData = new DatabaseEntry();
@SuppressWarnings("unchecked")
public static void main(String[] args)
{
Cursor cursor = null;
Transaction txn=null;
dbenv.setupenvironment();
try
{
txn = dbenv.getEnv().beginTransaction(null, null);
cursor = dbenv.getPrimaryDB().openCursor(txn, null);
String line = null;
BufferedReader br = new BufferedReader( new FileReader("W:/dhananjay/workspace/SMAXCDR/110618_154501.cdr"));
long startTime = System.currentTimeMillis();
while((line = br.readLine()) != null)
{

String[] sArray = line.split(",");
CDRData cdrfile = new CDRData();
theKey = new DatabaseEntry(sArray[0].getBytes("UTF-8"));
cdrfile.setId(sArray[0]);
cdrfile.setCallTime(sArray[1]);
cdrfile.setDisconnectTime(sArray[2]);
cdrfile.setIngressTrunkID(sArray[3]);
cdrfile.setIngressSignalingIP(sArray[4]);
cdrfile.setIngressMediaIP(sArray[5]);
cdrfile.setEgressTrunkID(sArray[6]);
cdrfile.setEgressSignalingIP(sArray[7]);
cdrfile.setEgressMediaIP(sArray[8]);
cdrfile.setANI(sArray[9]);
cdrfile.setDNID(sArray[10]);
cdrfile.setDNID_with_IngressPrefix(sArray[11]);
cdrfile.setDNID_with_EgressPrefix(sArray[12]);
cdrfile.setCodeMatch(sArray[13]);
cdrfile.setProtocol(sArray[14]);
cdrfile.setCallID(sArray[15]);
cdrfile.setSMaxCallID(sArray[16]);
cdrfile.setRingDuration(sArray[17]);
cdrfile.setPDDDuration(sArray[18]);
cdrfile.setRawDuration(sArray[19]);
cdrfile.setCauseCode(sArray[20]);
cdrfile.setTFlag(sArray[21]);
cdrfile.setRFlag(sArray[22]);
dbenv.getBinding().objectToEntry(cdrfile, theData);
cursor.put(theKey, theData);

}
cursor.close();
txn.commit();
dbenv.close();
long finishTime = System.currentTimeMillis();
System.out.println("The time taken by insert query : "(finishTime-startTime) " ms");
System.out.println("Record Inserted");
}

Cursors and transactions hang on to memory until they are closed/committed. You'll need to insert in batches, perhaps 1000. For each batch, close the cursor when done, commit the transaction, and then create new ones for the next batch.
