Performance problem with ojdbc14.jar

Hi,
We are having performance problem with ojdbc14.jar in selecting and updating (batch updates) entries in a table. The queries are taking minutes to execute. The same java code works fine with classes12.zip ans queries taking sub seconds to execute.
We have Oracle 9.2.0.5 Database Server and I have downloaded the ojdbc14.jar from Oracle site for the same. Tried executing the java code from windows 2000, Sun Solaris and Opteron machines and having the same problem.
Does any one know a solution to this problem? I also tried ojdbc14.jar meant for Oracle 10g, that did not help.
Please help.
Thanks
Yuva

My code is doing some thing which might be working well with classes12.zip and which does not work well with ojdbc14.jar? Any general suggestions to make the code better, especially for batch updates.
But for selecting a row from the table, I am using index columns in the where cluase. In the code using PreparedStatement, setting all the reuired fields. Here is the code. We have a huge index with 14 fields!!. All the parameters are for where clause.
if(longCallPStmt == null) {
longCallPStmt = conn.prepareStatement(longCallQuery);
log(Level.FINE, "CdrAggLoader: Loading tcdragg entry for "
+GeneralUtility.formatDate(cdrAgg.time_hour, "MM/dd/yy HH"));
longCallPStmt.clearParameters();
longCallPStmt.setInt(1, cdrAgg.iintrunkgroupid);
longCallPStmt.setInt(2, cdrAgg.iouttrunkgroupid);
longCallPStmt.setInt(3, cdrAgg.iintrunkgroupnumber);
longCallPStmt.setInt(4, cdrAgg.iouttrunkgroupnumber);
longCallPStmt.setInt(5, cdrAgg.istateregionid);
longCallPStmt.setTimestamp(6, cdrAgg.time_hour);
longCallPStmt.setInt(7, cdrAgg.icalltreatmentcode);
longCallPStmt.setInt(8, cdrAgg.icompletioncode);
longCallPStmt.setInt(9, cdrAgg.bcallcompleted);
longCallPStmt.setInt(10, cdrAgg.itodid);
longCallPStmt.setInt(11, cdrAgg.iasktodid);
longCallPStmt.setInt(12, cdrAgg.ibidtodid);
longCallPStmt.setInt(13, cdrAgg.iaskzoneid);
longCallPStmt.setInt(14, cdrAgg.ibidzoneid);
rs = longCallPStmt.executeQuery();
if(rs.next()) {
cdr_agg = new CdrAgg(
rs.getInt(1),
rs.getInt(2),
rs.getInt(3),
rs.getInt(4),
rs.getInt(5),
rs.getTimestamp(6),
rs.getInt(7),
rs.getInt(8),
rs.getInt(9),
rs.getInt(10),
rs.getInt(11),
rs.getInt(12),
rs.getInt(13),
rs.getInt(14),
rs.getInt(15),
rs.getInt(16)
}//if
end_time = System.currentTimeMillis();
log(Level.INFO, "CdrAggLoader: Loaded "+((cdr_agg==null)?0:1) + " "
+ GeneralUtility.formatDate(cdrAgg.time_hour, "MM/dd/yy HH")
+" tcdragg entry in "+(end_time - start_time)+" msecs");
} finally {
GeneralUtility.closeResultSet(rs);
GeneralUtility.closeStatement(pstmt);
Why that code works well for classes12.zip (comes back in around 10 msec) and not for ojdbc14.jar (comes back in 6-7 minutes)?
Please advise.

  • Problem with ojdbc14.jar (oracle10g Rel. 2 driver) in updating a BLOB field

    Hello All,
    Our web application uses oracle10g Release 2 jdbc driver with websphere 5.1.1.4 and oracle 9i. When it tries to update a BLOB field in the database updation is successful but it is updating that field with a null value. So rest of our application fails as this value is becoming null. We use an entity bean to update this table and websphere uses a prepared statement to update this table. Just before setting this BLOB field using setBinaryStream() on prepared statement I am printing to see whether it is null or not as shown in the code snippet below. And it is printing it correctly as non null. But after execution of the prepared statement some how the value stored in database is null.
    Is this a known issue with this driver? Does any one know work around or a solution to this? We have 3 BLOB fields in that table. Is that a problem? If we separate these BLOB fields into separate tables will the problem be solved? Any input on this is very much appreciated.
    // For column ORIGINAL_CONTENT
    byte[] tempbyteArray;
    tempbyteArray=(byte[])inputRecord.get(25);
    if (tempbyteArray == null) {
    System.out.println("DqPageBeanFunctionSet_f9c724af: tempbyteArray NULLLLLLL");
    } else {
    System.out.println("DqPageBeanFunctionSet_f9c724af: orig tempbyteArray length: " + tempbyteArray.length);
    if(tempbyteArray != null) {
    pstmt.setBinaryStream(25,new java.io.ByteArrayInputStream(tempbyteArray),tempbyteArray.length);
    else pstmt.setNull(25,java.sql.Types.BLOB);
    Thanks & Regards,

  • Problem using ojdbc14.jar in JDev 11g

    Hi
    I have an application created in 10g.
    I was trying to create the same in 11g and encountered this problem with the ojdbc14.jar.
    The jar has two classes OracleDataSource and OracleConnectionCacheImpl inside the same package.
    OracleConnectionCacheImpl is inherited from OracleDataSource.
    OracleDataSource has a protected variable called m_dataSourceName.
    The child class, OracleConnectionCacheImpl used this variable.
    I have this jar included in my classpath.
    When i run the application, it throws a runtime error.
    Following is the stack trace.

    I have checked the Oracle JDBC library of JDev 11g and found that it has ojdbc6.jar
    Is there any compatibility problem with this jar migrating from 10g to 11g?
    Found this related link but could not relate it much.
    Please explain
    JDBC problem: java.lang.NoSuchFieldError: CONNECTION_PROPERTY_THIN_NET_CONN
    Thanks

    I guess you can't use ojdbc14.jar that easy. Some dependencies form ojdbc14.jar are not available under 11g. That 's the reason you have ojdbc6.jar under 11g.

  • Performance problems with new Java Tiger style recommendations

    Performance problems with jdk 1.5 on Linux plattform
    (not tested on Windows, might be the same)
    using the new style recommendations.
    I need fast Vector loops for high speed mathematical calculations, some
    hints about the fastest way to program that loop would be also great!
    After refactoring using the new features from java 1.5 (as recommended from
    SUN) I lost performance significantly:
    using a vector:
    public Vector<unit> units;
    The new code (recommended from SUN for Java Tiger for redesign):
    for (unit u: units) u.accumulate();
    runs more than 30% slower than the old code:
    for (int i = 0; i < units.size(); i++) units.elementAt(i).accumulate();
    I expected the opposite.
    Is there any information available that helps?
    The following additional information I got from Mr. Shankar Unni:
    I got some fairly anomalous results comparing ArrayList and Vector: for the
    1.5-style loops, ArrayList was faster then Vector, but for a loop with get()
    calls, Vector was faster. Vector was even faster than that using
    elementAt(), which was a surprise:
    For a million summing iterations over a 100-element array:
    vector elementAt loop took 3446 ms.
    vector get loop took 3796 ms.
    vector iterator loop took 5469 ms.
    arraylist get loop took 4136 ms.
    arraylist iterator loop took 4668 ms.

    You can't expect miracles.  With over a million entries in your itab any select is going to take a bit of time. Do you really need all these records in the itab?  How many records is the select bringing back?  I'm assuming that you have got and are using indexes on your ZEEDMT_ZMON table. 
    In this situation, I'd first of all try to think of another way of running the query and restricting the amount of data, but if this were not possible I'd just run it in the background and accept that it is going to take a long time.

  • Performance problems with EP 6 and MS IE

    Hi everybody,
    since a couple of days, we are facing a sever performance problem with our SAP EP 6.0. When I access the system with MS Internet Explorer 6.0, it takes 5-10 minutes after the Login. With Firefox Browser, the performance is ok. Therefore I assume that it must be a problem with the IE settings. Does anybody know a solution?
    Best regards,
       Michael

    There are a few things that this could be.  I've seen the setting "Empty Temporary Internet Files folder when browser is closed" cause a lot of performance problems (This is in the advanced settings in your IE).
    This will cause your cache to be cleared out each time the browser is closed and cause a lot more data to be downloaded each time you login to the system.
    For more analysis I'd recommend putting a tool like HTTPWatch into your IE browser and seeing which requests are using the most time.

  • Performance problem with Mavericks.

    Performance problem with Mavericks. My Mac is extremly slow after upgrading to Mavericks. What can i do to solve that?

    If you are still experiencing slow down issues, it maybe because of a few other reasons.
    Our experience with OS X upgrades, and Mavericks is no exception, is that users have installed a combination of third party software and/or hardware that is incompatible and/or is outdated that causes many negative performance issues when upgrading to a new OS X version.
    Your Mac's hard drive maybe getting full.
    Do you run any antivirus software on your Mac? Commercial Antivirus software can slow down and negatively impact the normal operation of OS X.
    Do you have apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, TuneUpMyMac or anything like these apps, installed on your Mac? These types of apps, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.
    Your Mac may have way too many applications launching at startup/login.
    Your Mac may have old, non-updated or incompatible software installed.
    Your Mac could have incompatible or outdated web browser extensions, plugins or add-ons.
    Your Mac could have connected third party hardware that needs updated device drivers.
    It would help us to help you if we could have some more technical info about your iMac.
    If you so choose, please download, install and run Etrecheck.

  • Performance problem with Orcacle / Crystal reports 8.5 / ASP

    Hi,
    I have a performance problem with reports running crystal reports 8.5 with oracle databases.
    Fetching data appears to be slow. Oracle trace reports (tkprof) shows that fetchsize=1.
    Fetchsize in Oracle ODBC is 15 (default).
    How can I update te fetchsize in crystal reports?
    I would appreciate any help.

    CR XI R2 is also still available for purchase. This is the last version of CR to use the RDC. Contact sales at 866-681-3435.
    Make sure the installed versin is 11.5.12.1838 - if it is not, apply SP6:

  • Performance problem with recordset object

    Hi,
    I have a performance problem with record set object. Is it true using RecordSet object as argument to the method will cause any perfomance degradation?
    here is my code.
    finStmtList = selectFinancialStatements(rs, shortFormat, latestOnly, true);
    I changed the code by populating the recordset in the method that called the above statement. previously the population of valueobject is within the select FinancialStatements.
    Now the method looks like
    finStmtList = selectFinancialStatements(ValueObject, shortFormat, latestOnly, true);
    Is this fix will result in any performance gain?

    Can any one suggest me that the above RecordSet Object contains large number of records that counts up to 1000 rows and having 30 columns? I tested the application. But the performance varies from time to time.
    Is there any other way to fine tune it?

  • Performance problem with sdn_nn - new 10g install

    I am having a performance problem with sdn_nn after migrating to a new machine. The old Oracle version was 9.0.1.4. The new is 10g. The new machine is faster in general. Most (non-spatial) batch processes run in half the time. However, the below statement is radically slower. The below statement ran in 45 minutes before. On the new machine it hasn't finished after 10 hours. I am able to get a 5% sample of the customers to finish in 45 minutes.
    Does anyone have any ideas on how to approach this problem? Any chance something isn't installed correctly on the new machine (the nth version of the query finishe, albeit 20 times slower)?
    Appreciate any help. Thanks.

    create table nearest_store
    as
    select /*+ ordered */
    a.customer_id,
    b.store_id nearest_store,
    round(mdsys.sdo_nn_distance(1),4) distance
    from customers a,
    stores b
    where mdsys.sdo_nn(

    'sdo_num_res=1, unit=mile',
    1
    ) = 'TRUE'
    ;

    Dan,
    customers 110,000 (involved in this query)
    stores 28,000
    Here is the execution plan on the current machine:
    CREATE TABLE STATEMENT cost = 81947
    LOAD AS SELECT
    PX COORDINATOR
    PX SEND QC (RANDOM) :TQ10000
    ROW NESTED LOOPS
    1 1 PX BLOCK ITERATOR
    1 1ROW TABLE ACCESS FULL CUSTOMERS
    1 3 PARTITION RANGE ALL
    1 3 TABLE ACCESS BY LOCAL INDEX ROWID STORES
    DOMAIN INDEX STORES_SIDX
    I can't capture the execution plan on the old database. It is gone. I don't remember it being any different from the above (full scan customers, probe stores index once for each row in customers).
    I am trying the query without the create table (just doing a count). I'll let you know on that one.
    I am at 10.0.1.3.
    Here is how I created the index:
    create index stores_sidx
    on stores(geometry)
    indextype is mdsys.spatial_index LOCAL
    Note that the stores table is partitioned by range on store type. There are three store types (each in its own partition). The query returns the nearest store of each type (three rows per customer). This is by design (based on the documented behavior of sdo_nn).
    In addition to running the query without the CTAS, I am also going try running it on a different machine tonight. I let you know how that turns out.
    The reason I ask about the install, is that the Database Quick Installation Guide for Solaris says this:
    "If you intend to use Oracle JVM or Oracle interMedia, you must install the Oracle Database 10g Products installation type from the Companion CD. This installation optimizes the performance of those products on your system."
    And, the Database Installlation Guide says:
    "If you plan to use Oracle JVM or Oracle interMedia, Oracle strongly recommends that you install the natively compiled Java libraries (NCOMPs) used by those products from the Oracle Database 10g Companion CD. These libraries are required to improve the performance of the products on your platform."
    Based on that, I am suspicious that maybe I have the product installed on the new machine, but not correctly (forgot to set fast=true).
    Let me know if you think of anything else you'd like to see. Thanks.

    Hi,
    This is what I know and please if any expert think its incorrect, please do correct me.
    BSEG is a cluster table with BUKRS, BELNR, GJAHR and BUZEI as the key whereas other key will be stored in database as raw data thus SAP apps will need to convert that raw data first if we are using other keys in where condition. Hence, I suggest to use up to buzei in the where condition and filter other condition in internal table level like using Delete statement. Hope its help.

    Abraham

  • Performance problem with Oracle

    We are currently getting a system developed in Unix/Weblogic/Tomcat/Oracle environment. We have developed a screen that contains 5 or 6 different parameters to select from. We could select multiple parameters in each of these selections. The idea behind the subsequent screens is to attach information to already existing data/ possible future data that matches the selection criteria.
    Based on these selections, existing data located within the system in a table is searched and those that match are selected. Also new rows are created in the table against combinations that do not currently have a match. Frequently multiple parameters are selected, and 2000 different combinations need to be searched in the table. Of these selections, only about 100 or 200 combinations will be available in existing data. So the system is having to insert 1800 rows. The user meanwhile waits for the system to come up with data based on their selections. The user is not willing to wait more than 30 seconds to get to the next screen. In the above mentioned scenario, the system takes more than an hour to insert the new records and bring the information up. We need suggestions to see if the performance can be improved this drastically. If not what are the alternatives? Thanks

    The #1 cause for performance problems with Oracle is not using it correctly.
    I find it hard to believe that with the small data volumes mentioned, that you can have perfornance problems.
    You need to perform a sanity check. Are you using Oracle correctly? Do you know what bind variables are? Are you using indexes correctly? Are you using PL/SQL correctly? Is the instance setup correctly? What about storage, are you using SAME (RAID10) or something else? Etc.
    Facts. Oracle peforms exceptionally well. Oracle exceptionally well.
    Simple example from a benchmark I did on this exact same subject. App-tier developers not understanding and not using Oracle correctly. Incorrect usage of Oracle doing a 100,000 SQL statements. 24+ minutes elapsed time. Doing those exact same 100,000 SQL statement correctly (using bind variables) - 8 seconds elapsed time. (benchmark using Oracle 10.1.0.3 on a Sunfire V20z server)
    But then you need to use Oracle correctly. Are you familiar with the Oracle Concepts Guide? Have you read the Oracle Application Developer Fundamentals Guide?
