hi all,
i have some mission critical tasks into my project, is it possible to persist
10 000 record per seconds,
1. AS - JBoss Application Server 4.0.4GA
2. Database - Oracle 10G 10.2.0.1
3.EJB - 3.0 Framework
4.OS - SunOS 5.10
4.Server - Memory: 16G phys mem, 31G swap, 16 CPU,
i know that i need performace
here is my configurations about performance
1. JVM Config Into JBoss
| JAVA_OPTS="-server -Xmx3168m -Xms2144m -Xmn1g -Xss256k -d64
-XX:PermSize=128m -XX:MaxPermSize=256m
| -Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000
| -XX:ParallelGCThreads=20 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC
| -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90
-XX:MaxTenuringThreshold=31 -XX:+AggressiveOpts
| -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails
-XX:+PrintTenuringDistribution
|
2. Also i have one simple Stlateless Session Bean
| @Stateless
| @Remote(UsageFasade.class)
| public class UsageFasadeBean implements UsageFasade {
|
| @PersistenceContext(unitName = "CustomerCareOracle")
| private EntityManager oracleManager;
| @TransactionAttribute(TransactionAttributeType.REQUIRED)
| public long createUsage(UsageObject usageObject, UserContext context)
| throws UserManagerException, CCareException {
| try {
| oracleManager
| .createNativeQuery("INSERT INTO USAGE "
| + " (ID, SESSION_ID,
SUBSCRIBER_ID, RECDATE, STARTDATE, APPLIEDVERSION_ID, CHARGINGPROFILE_ID,
TOTALTIME, TOTALUNITS, IDENTIFIERTYPE_ID, IDENTIFIER, PARTNO, CALLTYPE_ID,
USAGETYPE, APARTY, BPARTY, CPARTY, IMEI, SPECIFICCALLTYPE, APN, SOURCELOCATION,
SMSCADDRESS, MSC_ID, ENDREASON, USAGEORIGIN, BILL_ID, CONTRACT_ID) "
| + "
VALUES(SEQ_USAGE_ID.NEXTVAL, NULL, NULL, SYSDATE, SYSDATE, NULL, NULL, NULL,
NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL,
NULL, NULL, NULL, NULL, NULL, NULL) ");
| return 1;
| } catch (Exception e) {
|
| }
| }
| }
|
3. and into client side i have 200 Threads, each of them tried to call this
method 50 times
my result is that i can persist 10000 record in 20 seconds, without hibernate,
with hibernate i got worst result :(,
also i hear that it is good idea to use JDBC 3.0 driver for performance,
i download newest oracle jdbc jar file from oracle site
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc_10201.html
is this jar file JDBC 3.0 driver ?
is it any more performance tuning into JBoss or EJB with entity beans?
can anybody help me ? or is there any doc which can help me ?
Regards,
Paata,
