EXCEPTION_ACCESS_VIOLATION error with MS ACCESS database connection
Hello,
I got the EXCEPTION_ACCESS_VIOLATION error in the hs_err_pidXXXX.log file.
I am using MS ACCESS and jdbc-odbc bridge to access to it.
The problem is the tomcat server crashes every a couple of hours.
The error log is attached.
I searched this error on line and tried a couple of things that they suggested. But no helps.
I tried increasing the heap size, and change the Java option to -Xint.
But all no help.
Would you take a look at the log file and suggest anythings?
Thank you!!!

1. Get another driver. The only one known is java only so it wont crash. But is not not free.
2. Use a proxy driver. That means that another app actually does the database work. If it crashes you just start it again (which you can do in your main code.) That way it won't take down your server. There are commercial jdbc drivers that claim MS Access but are are really just proxy implementations as an option in this area. -
Oracle Database Connection using JSP
I am attempting to create a simple web app using Oracle 9i and JSP. I am trying to create a connection to my database and do not seem to be having much luck. I have worked with ASP and can find my way around fairly well in that environment, however, JSP seems to be not as closely related as I initially thought. Can anyone point me to a good site that can give a beginner the basics on using this technology. I have been to several sites off of Oracle and Sun, but I seem to be more confused after reading them. With JSP, can I code as I would in ASP i.e JavaScript, etc? I have downloaded and installed the JDBC drivers from Oracle's website, but I receive errors when trying to establish a connection. If there is a site that can explain from the ground up how to set up a connection, I would be very greatful!
Hi,
This example uses Interbase, but hopefully you will find it useful anyway -

Jsp and database connection using bean
* I want create a bean to handle database connectivity.The
<jsp:usebean> tag uses
no argument constructor ..so I cannot pass the userid and password to
the constructor.
So how can I create a database connection when the user_id and password
will be a part of parameter ?
* Now I'm opening database connection in the jsp scriplets. Everytime I
refresh the
jsp page a new connection is created ? Is it not going to choke the
database ? I cannot use connection pool because every user logs in with
different userid.
Thanks
You can pass your arguments in this way:
<jsp:usebean id="myBean" scope="page"/>
<jsp:setProperty name="myBean" property="userId", value=<%= user_id%>/>
<jsp:setProperty name="myBean" property="password", value=<%=
user_password%>/>
of course, in your bean class, you should create two setter methods,
setUserId and setPassword.
Hopefully, this will help you.

Error While creating new database connection from HFM workspace
Hi,
We have recently installed HFM and was trying to create database connection from database connection manager in HFM workspace.
I am getting below error:
"Error connecting to database connection : no HssJNIDriver950 in java.library.path" initially and later
"Error connecting to database connection : com/hyperion/ap/adm/HssConn".
Any information in this direction would helpful.
Thanks,
Bhargav
Edited by: bhargavr on Jan 24, 2011 6:55 PMHi bhargavr,
We came accross the same issue. Try the following solution below for this 'KNOWN ISSUE' and let me know how you get on. Drop me a note if you have any questions regarding this post.
Error: *"Error connecting to database connection: com/hyperion/ap/adm/HssConn" While Creating a Financial Management Database Connection* [ID 1102697.1]
Modified 04-JAN-2011 Type PROBLEM Status PUBLISHED
Applies to:
Hyperion BI+ - Version: 11.1.2.0.00 and later [Release: 11.1 and later ]
Microsoft Windows x64 (64-bit)
Symptoms:
You are running the Financial Reporting Web Server on a 64-bit server.
When you try to create a new Financial Management (HFM) database connection using the Database Connection Manager in Workspace you receive the following message:
“Error connecting to database connection <connection_name>: com/hyperion/ap/adm/HssConn”
You can create a database connection in Financial Reporting Studio. When you refresh a report with a Financial Management database connection, you receive one of the following messages:
“1001: Error connecting to database connection <DATABASE_CONNECTION_NAME>: com/hyperion/ap/adm/HssConn”
or
“1001: Error connecting to database connection <DATABASE_CONNECTION_NAME>: no HssJNIDriver950 in java.library.path”
Cause:
The issue is documented in unpublished bug 9537050, and in Known Issues in the 11.1.2 Reporting and Analysis Readme. Cross-reference unpublished bug 9707353.
Solution:
In the Windows registry, take the following steps:
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\HyperionSolutions\FinancialReporting0\HyS9FRReports.
For each of the following entries, prefix the contents with text in the blue box: Env2, JVMOption13, and JVMOption17 (note that the JVMOption numbers might be slightly different in your environment).
C:\Oracle\Middleware\EPMSystem11R1\common\ADM\11.1.2.0\bin-64
If your EPM_ORACLE_HOME is not located at C:\Oracle\Middleware\EPMSystem11R1, replace that location with your location.
Restart the server.

how should you close the connection? like this: conn.close();
that said, doing this in a JSP page is bad form and not recommended
JSP's typically don't contain ANY business or data logic -
How to create database connection using DB2Driver in JDeveloper 10.1.2.1.0?
I am trying to create a JDeveloper/Data Connection using com.oracle.ias.jdbc.db2.DB2Driver. The driver is registered from a User Libraries: DataDirect JDBC. I have the following class path for the library:
E:\DataDirect\3.4\lib\YMdb2.jar;E:\DataDirect\3.4\lib\YMbase.jar;E:\DataDirect\3.4\lib\YMutil.jar
I have no trouble configuring the connection but when I test it and I got No suitable driver Vendor code 0. Whats wrong? I have successfully created several database connections using Oracle thin driver. This is first time I am using a third party driver. Has any one successfully create a database connection using the com.oracle.ias.jdbc.db2.DB2Driver?Hi
Since the error points to the unavailability of the driver class,can you double check your library claspath entries again.
I just tried a DB2 connection using the following properties and the connection went through fine:
Driver class name: com.oracle.ias.jdbc.db2.DB2Driver
URL: jdbc:merant:db2://<host_name>:50000;DatabaseName=SAMPLE
Thanks

Problem in Oracle Database Connectivity in JSP
I am having big problem such as Oracle Database connectivity problem
Following code i am used for database connection. but it throw an exception call class not found exception.
Pls any one can help me. With a sample code for Oracle Database connection in JSP
Class.forName ("oracle.jdbc.driver.OracleDriver");
String url="jdbc:oracle:thin:@172.25.44.54:1521:bbo";
con = DriverManager.getConnection(url,"user", "user123");
Thank youWell i've never used oracle or their drivers before but i'm presuming that you'd go to oracle.com or something and look for downloads. Otherwise you could goodle for Oracle JDBC drivers. Then just follow the instructions.
Again i've never used JSP but if you have a manifest file somewhere you'll need to put a class-path: entry in their referecning the jar file with the driver so that it is availble at run-time.

Checking Oracle Database availblity using JSP
Hello All,
How to check the database availablity using JSP like whether the TNS Listener is up or not, or the whole database is up or not.
Thanks
RahulHi,
To see if your listener is up or down you can use the lsnrctl status, and to start use start option. You can make a similar operation for database, use the sqlplus program.
Another option is program a batch script, if you wan't use the commands.

Error in new/select database connection
i am new at sql developer. i am getting the following error in new/select database connection
I have filled the following details
Connection Name : hr_orcl
Username : hr
Password : hr
Connection Typer: Basic, Role: Default
Hostname: localhost
Port : 1521
SID : orcl
I click on TEST & get the following error message displayed
" Status : Failure -Test failed: Listener refused connection with the following error:ORA-12505, TNS:listener does not currently know of SID given in connec desciptor"Hi,
You don't say if you actually have a local database installed. If not, you need too. If you already do, then the most common case is Oracle 10g or 11g Express Edition. In that case the default SID is XE, as noted in the following similar thread:
Re: Connecting to Oracle Database 10g Express Edition
If you need to install a database, you can get 10g or 11g XE here:
http://www.oracle.com/technetwork/database/express-edition/downloads/index.html
The 10g XE release has a smaller memory and disk footprint if that makes a difference to you.

Crystal Reports and Access database connection error
I had this in a different forum with no hits, so I am trying this one.
A person that I work with has multiple reports set up that pulls from an Access database that is password protected. When we moved everything over to a new computer, those reports now say that it cannot access the fields inside the database. It never pops up with a login screen either, like it does on the old computer. I played around with the ODBC, with no luck, couldn't get anything to work. I have also tryed relinking the database, but I keep getting connection problems. We are on a network, so her settings should have all moved with the new computer. Along with the database and the reports being on the server, so they were never moved. I am thinking it has something to do with a system file.
I also found this document on this site, but cannot find the download it mentions, sounds similar to my problem.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/208b8fe5-681e-2b10-d2bb-b201f266d0ab
Does anybody know how to fix this without the utility mentioned in the above link, or know where I can get the utility??

CA Forum: Crystal Reports
Hello Chris,
Crystal Reports does not store the database password with the RPT file. This is by design (Crystal is not a database security product). This is true of all versions of Crystal Reports.
If your users need to see fresh data when opening the reports then they will have to log in by providing at least the password.
You can send reports with Saved Data that won't try to hit the database, but the data won't refresh either. To save data with the report go to the File menu and click next to Save Data with Report. Refresh the report and then save it. The report will now have saved data and won't try to hit the database when opened. If the user hits the refresh button then they will get prompted to log into the database.
I hope this helps.
