Slow performance of JDBC - ODBC MS ACCESS

I experience a very slow performance for jdbc-odbc using ms access as the database. This program works fine with other computer (in term of performance). However, the harddrive is cranking big time with this computer (this is the fastest one among the computers I tested, and also has many gigabytes left to be used). The database is very small. Other computer use exactly the same java version and msaccess driver version. If anyone found the same problem, or have any suggestion please help. Thank you.

I am having the same problem with one machine as well. Running MS Access 2000 (unfortunately), and all machines run well with one exception. DB reads take about 10 seconds each. If a solution has been found, please report.

JDBC/ODBC Local Access

I have wrote a JApplet code that using JDBC/ODBC bridge to connecting a local Database (MS Access).

(I have five class file and I have used them in a signed jar file)
when I change the code and run it as an JFrame Application it works correctly.(without signing and jar file)
What can I do to solving this problem?
Thanks a lot,
Payam

I found the answer by myself:
the application was finding a copy of .class in my classpath before it finds the one in the jar file.

JDBC-ODBC Bridge Performance To MS Access

Hey all, I'm running a Java app that extracts an entire table (set of tables) from Oracle and copies them into Access. The easiest implementation has been to use a DSN-less Type 1 JDBC-ODBC bridge connection to Access, but unfortunately the inserts are taking too long.
I have tried both Statement and PreparedStatement approaches, with both single row and batch updates. Some of the performance times, relative to the computer I am on (PIII 1 gHz with 256 RAM), are as follows:
Via Batch, about 8min, 15 seconds per 10,000 rows.
Via Single Row updates/inserts, about 52 minutes for 45,000 rows.
I've tried alot of varieties with batch, but 10,000 seemed to be the best. The largest table is only 45,000 rows (right now), but has the potential to grow much larger (obviously). This application needs to backup 4 databases, each with N tables (current N=7, but will expand). I'm trying to knock down the times and increase performance, but am not sure what is "reasonable" for Type 1 connections with JDBC. I've seen third party drivers, Type 3, for Access...but don't want to run the middle tier server for filtering request through. I'd rather use Type 4, but can't seem to find any for Access.
Any suggestions? Recommendations? Let me know! Thanks all! :)

Hi,
If its a backup/batch process why are you worrying about performance, its only an offline process :) even if has to be triggered during an OLTP run this task asynchronously.
I dont know why you have chosen java to do this ??? any way prepared statements with non scrollable resultsets will increase you performance better tha scrollable normal statements.

Very slow performance with queries sent to MS Access

Hi, folks,
I'm developing a site with JSP and MS Access and I'm having a lot of DB headaches. Since the site is still under development (not released yet), I'm using very small tables (like 20 rows, 20 columns).
The first problem was that every time I executed ResultSet.getXXX() it took 50-100 ms. This made a page with little data (200 values read) take more than 30 seconds to display (!!!). I solved this issue changing the old jdbc:odbc for a brand new (trial) Netdirect JDataConnect driver (I include this info mainly because I think that may be helpful for some people out there).
Now I have significantly reduced time consumption, but still the Statement.executeQuery() sentence has a terrible performance. I've measured 2 to 3 seconds for each query to return. I think that this is not logical for such small tables (What could happen with the 50,000 rows tables that we are planning to use in the future!).
As always, thanks in advance for any help.

It's been some days since my last post, but I have got valuable info in this time.
First, answering your question, Sun's jdbc:odbc bridge only supports one isolation level: TRANSACTION_READ_COMMITED (at least for MS Access), so it's not possible to try to change it.
However, I've discovered that a good solution to improve performance is to use another driver. Right now I'm using one from Atinav that dramatically improves performance (from 30 seconds to 300 ms).
The problem with this driver is that it only supports JDBC 1.0, so I can't even use a scrollable ResultSet.
Right now I think that I would be happy if I found I driver with a performance similar to Atinav's, but also supporting at least JDBC 2.0.
As always, thanks in advance for any help.

JDBC-ODBC Bridge seems to slow down after a while

Hi,
I've got a weird problem going on with an application I'm writing. I hope someone can tell me what I'm doing wrong.
The problem I'm encountering is in he code shown below. The function getAllGamesForATeam is creating a list of items in an ArrayList and passing it back to an Event handler so that I can put it in the session of a servlet. The first time I run this code, it is fast. Fast enough to use on a servlet. The second time it runs, it is MUCH slower...too slow to use on a servlet. The third time it runs, it gets even worse.
I am using the JDBC-ODBC bridge to access my database which is in Access 97. I do have connection pooling enabled on the database. Still it is slow.
If you have any ideas, I would appreciate it. Here's the code:

Where do you close the ResultSet?
Where do you close the Statement?
Presumably you only create one connection for all users or you close it somewhere.

JDBC-ODBC Bridge is too slow

Why the Sun JDBC-ODBC Bridge is so slow? When i use the ms bridge it is as faster than a JDBC connection, but i found a bug on the ms bridge that it returns NULL when the value is a "" (blank)
Anyone how to make sun bridge has a acceptable perfomance?
I am using MySQL 3.23 and tested on Sun JDKs 1.1.8, 1.2, 1.4
My comp is a K6-2 400 with 128 RAM
Thanks

   I've found using a pure JDBC driver (ashna's JTurbo) to be
   roughly 40% faster than the bridge after doing some
   (admitidly) small amount of bench testing. I also found
   it resolved a number of issues (bugs??) with the bridge
   (e.g. no longer throws an occasional fractional truncation
   exception when inserting timestamps). As for the bridge
   being used only for test purposes check out this URL:
   http://java.sun.com/J2se/1.3.0/docs/guide/jdbc/getstart/bridge.doc.html
   They recommend using the bridge only for experimental use or when a
   pure driver is not available. I guess you could consider this as test purposes only.There is no such thing as a 'pure driver' (or 'pure jdbc driver' from a different post.)
The doc you site suggests a 'pure java' driver - a type 4. I question that. I know there are number of things that one can do in ODBC and in OCI which speed up requests. And obviously one can't do those in java.
Performance problems are caused by the following:
-Requirements-most impact
-Design
-Environment (cpu,network,thread, etc bottlenecks)
-Language/intefaces - least impact.
Changing requirements/design can easily produce impacts of orders of magnitude (by removing one requirement I reduce a 4-8 hour report to less than 30 seconds.) So how much impact did the 40% you saw impact your total application? Did you profile your application/system under load using a automated tool to measure the speed?
I would suspect also that the suggestion that the driver is 'experimental use or when no other alternative is available' might be slightly biased as the driver was produced by Merant who is actively selling drivers too. One would suppose that they were not allowed to deliberately introduce bugs into the code. However, they might have insisted that some language be introduced to suggest that someone should buy the product.

   But i can't believe i've tested today again and the sun
   bridge is working as fast the ms bridge! i can't
   understand, yesterday i've tested a million times

   what's happened yesterdayDid you use a closed network? Did you use isolated servers?

MS access,servlets and jdbc-odbc

when i try to connect to ms access database using servlet i get unable to open registry key DriverId problem.
servlet successfully extracts the form data.Even jdbc code alone works fine, but when jdbc code is embeded in servlet I get the above error.I am using java web server 2.0 and a jdbc-odbc(type 1) driver.
Please help me.................!
I cannot proceed with my project without solving this problem.

You have not specified the exception class.
If it is java.security, try peeping into jws security directory, and set the access to your servlet directory.
I do not know this helped you or not.

Cannot access remote FoxPro dbf file using jdbc-odbc and system DSN

Hi all,
I have a foxpro database sitting on remote server (netware server). the dbf folder is shared and I can access it using windows explore on my weblogic server (windows 2003). I created a system dsn for that. I can access the database from the a stand alone java program using
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection surgConn = DriverManager.getConnection("jdbc:odbc:FoxDB", " ", " ");
But when I use the same thing in my weblogic 8.1 application, I cannot access the database. I didn't config any data source in weblogic 8.1
Why?
When I try this on my own computer - windows 2000, weblogic 8.1 workshop. remote foxpro database dbf folder. it works.
Any idea?
Thanks very much

User/password are usually necessary to set up the ODBC source. So you may need find out who set up your ODBC source. Or you need find the correct user/password and reset the ODBC source.

JSP connected to MS Access using JDBC-ODBC

If I want to run a jsp file connected to a MS Access database using jdbc-odbc bridge.
I thought that I should use the following code to make the connection:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String database = "jdbc:odbc:Driver={Microsoft Access Driver(*.mdb)}; DBQ=http://myComputerName:8080/examples/jsp/DatabaseTest/mydatabase.mdb;DriverID=22;READONLY=fals";
sqlca = DriverManager.getConnection(database, "dba","sql");
but Tomcat 4.1 produces many errors.
The file runs fine when I determine the complete path and include the local drive (C://) of the database Like the following:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String database = "jdbc:odbc:Driver={Microsoft Access Driver(*.mdb)};
DBQ=C:/Tomcat4.1/webapps/examples/jsp/DatabaseTest/mydatabase.mdb;DriverID=22;READONLY=fals";
sqlca = DriverManager.getConnection(database, "dba","sql");
Of course I do not want to use the second code because I want to use my computer as a host.
I will appreciate any answer!

Yes, using the DSN, it works fine.
But, I think it will run from the drive C.
I want to use my computer as a host. So, I think that I should include the name of the computer in the path.
I do not know may I am confused.
I appreciate your reply. Thanks!

Access MS-Access using JDBC ODBC bridge from Sun AMD64

Hi,
We are trying to configure a communication channel using the JDBC adapter. We are setting the driver to the JDBC-ODBC bridge driver and trying to access an MS Acess database from the PI server(sun amd64). When we set the driver to the JDBC-ODBC bridge, the J2EE engine tries to restart immediately and does not start. The std_server.out contains the following error:
Service com.sap.aii.adapter.jdbc.svc started. (234 ms).

Has anybody been able to configure the JDBC-ODBC bridge driver for MS Access? Also, has anybody used the database vendor(MS) drivers? If so, where are they available.
Thanks in advance

Slow performance in W2K using Oracle ODBC Driver

My company is upgrading our NT4 servers to W2K. One or our App servers is running MTS with several packages, one of those being a dataaccess package that is responsible for all data actions.
In testing the OS upgrade, I found considerable performance degradation with our data access package. I finally solved the problem by changing the ODBC driver from Oracle ODBC Driver to the Microsoft ODBC for Oracle Driver. I have also found that under XP, I can still retain the use of the Oracle ODBC Driver without any performance hits.
All systems currently have the 8.1.7 Oracle Client and MDAC 2.7. I have also tried the Oracle Objects for OLE with similar performance losses in W2K.
More info about the problem...
In using the Oracle ODBC Driver, I connect this way -
Dim RS As ADOR.Recordset
Set RS = CreateObject("ADOR.Recordset")
RS.ActiveConnection = "DSN=" & p_strDSN & ";" & "uid=" & strUser & ";pwd=" & strPassword & ";"
RS.Source = "Select stuff from aTable"
RS.LockType = adLockReadOnly
RS.Open
Using W2K, I found that the majority of processing time comes from the RS.ActiveConnection call, not from object creation.
I would like to use an Oracle developed driver to connect to my database, however, I am forced to use the Microsoft driver. I have not seen any similar problem on this message board, nor have I seen any mention of this in MSDN's discussion board. Can anyone shed some light on what is going on?
Thanks,
Matt

The performance lag we have been seeing is in the milliseconds, but when we make repeated calls, those milliseconds add up. I am seeing a difference of about 7 - 10 milliseconds each call between the Oracle ODBC Driver and the Microsoft driver.
TNSPings seem quick in all setups as does the connection tests.
The Oracle ODBC driver version is 8.01.07.00. I haven't tried the new 8.01.07.6+ drivers yet. I'll give them a shot and reply back with results in a day or so.

JDBC-ODBC Bridge Drivers and Microsoft Access

Are there any good tutorials on setting this up? Forgive me if there is one on this site - I couldn't find it. I just know (from some other sites) that it can be a pain to set up and get working right.

I mean installing and configuring JDBC-ODBC to be
able to connect to Access...I know about JDBC and
it's API. I just need to know how to configure
everything so that I can use the API.If you have a version of windows (at least back to 95) that doesn't have the MS Access ODBC driver and/or doesn't have the ODBC shell then something is wrong with your windows.

Problem with locks while using iBATIS with MS Access through JDBC-ODBC brid

Hello,
I am attempting to use iBATIS to access MS Access file via JDBC-ODBC bridge.
(I am using Spring's "SqlMapClientDaoSupport," but that is probably irrelevant)
All this runs on Tomcat... First time DB gets accessed the LDB lock file is created. From there on the only way I can remove the lock file is to kill the JVM...
Any help is greatly appreciated...

And why is that a problem?
