Database Connection Methods

I have 2 large databases to which Hyperion connects. One is an Oracle 9i Database, the other is a DB2 8.2 Database. It should also be noted that these databases are also connected to one another (using a federated link (DB2 to Oracle) and using an Oracle Transparent Gateway (Oracle to DB2). I am interested in what is best practice for connecting to these databases. We have considered the following options however please indicate where other preferable options exist.
1. Using ODBC connection (Oracle at Orahome 92 drivers)
2. Using ODBC connection (Merant OEM 5.1 32 BIT Oracle Wire Protocol drivers)
3. Connect using Oracle Net
However, we have seen some issues using some of the methods stated above.
A. ODBC connection (Oracle at Orahome 92 drivers)
--> When selecting from tables on the DB2 database (connecting across the Oracle Transparent Gateway) this fails with error �ORA-1002: fetch out of sequence�
--> Does not allow the filtering of tables from the catalogue within the OCE.
Has any body had any similar findings or had any issues with the Merant drivers or Oracle Net?

If you use "Connect using Oracle Net" this connection
you need to avoid outer join
because it supports outer join once only
Rest depend upon your scenario

Java database connection method class for review

Can you guys tell me any specific coding standard has to be followed here(i guess i need not hard code the pwd's)
import java.sql.*;
public class DBLocator {
     * Obtains and returns a connection to database
     * @return database connection
     public static Connection getConnection() {
     Connection con = null;
     try {
          Class.forName("com.informix.jdbc.IfxDriver");
          String url = "jdbc:informix-sqli://151.140.160.201:1527/ssde_db:INFORMIXSERVER=ssde_infx";
     con = DriverManager.getConnection(url,"haha06","123123");
} catch (ClassNotFoundException e) {
               System.out.println("Driver not found");
          } catch (SQLException e) {
               System.out.println("SQL exception");
               e.printStackTrace();
          return con; // returns connection
}

Can you guys tell me any specific coding standard has
to be followed here(i guess i need not hard code the
pwd's)More than just the passwords. Why are the driver class and URL hard-coded?
I wouldn't use this class. It's not very useful as written. It's a poor abstraction for one. There's lots of other useful things that you could include, like methods for closing and rolling back a connection, closing a statement and result set. You don't log any exceptions or messages. You preclude the use of a connection pool managed by an Java EE app server.

Database Connection Error: '42S02..... in Crystal Reports XI Developer

I get the above error within CR XI Developer when I try to connect an ODBC link to a Visual FoxPro database (.DBC).
The full messsage is:
Database Connection Error: '42S02:[Microsoft][ODBC Visual FoxPro Driver] Not a table. [Database Vender code: 123]'
This is a headache and any assistance in solving this problem would be greatly appreciated.

Hi Bob,
First you should go to this link: http://www.sdn.sap.com/irj/boc and download the trial version of CR XI R2 and use your XI keycode, then apply the patches which you can get to by clicking on the BusinessObjects tab above, then Downloads.
Direct link to the Trial version: http://www.sap.com/solutions/sapbusinessobjects/sme/freetrials/index.epx
Download SP5 and then test again. If it's still an issue we can at least escalate the problem. CR Xi is past it's supported life cycle meaning no patches will be released.
Have you tried using any other database connection methods to see if those work? May be an issue with the ODBC driver. Try downloading the latest MDAC from microsoft also.
Thank you
Don

Unable to use "easy connect" method to XE database

All,
I have an XE database running on Oracle Enterprise Linux. If I create a tnsnames.ora entry I can connect to the server fine. However, if I try to connect via the easy connect method
sqlplus user@host:port:sid it fails with
Enter password:
ERROR:
ORA-12545: Connect failed because target host or object does not exist
the hostname I am using is definitely correct and I've also tried with ip address and get same error message. If I change from SID to SERVICE_NAME
sqlplus user@host:port/service
I get the following error message
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
I've used both XE and xe as service name. The service name in my tnsnames.ora entry that works uses lower case xe for service name.
Any help out there would be appreciated.

Maybe this is more significant for you ?

Closing the database connection after report in a server application

I searched these forums and the internet for a definitive answer on asking the Crystal SDK for java to close the jdbc connection after it has generated a report. We have been using the Crystal Report SDK to generate reports within our JEE application, built upon the Spring framework, for the past two years. It works well, especially if you prepare views in the database for your reports.
From what I can tell once you have used ReportClientDocument to create your report you all the close() method to release resources associated with report generation, but this does not close the jdbc database connection.
Further research states that if you are using the CrystalReportViewer you can call the dispose method to close the database connection. We are not using JSP nor this class, so that does us little good.
Finally I found a post that one could call ((AdvancedReportDocument)reportClientDocument.getReportSource()).dispose(). This doesn't drop the connection either.
Each report actually opens 3 connections according to SQL Server. Each report will reuse the connections it has open, so for 50 reports, theoretically, we could have up to 150 connections. We explained to our client those connections remain inactive, however this is unacceptable to our client as they would like to minimize the number of connections left open to their database.
If anyone can post any further information on this issue, it is much appreciated.

Yes, another team member found the issue. Quite embarrassing really I didn't see it. I was looking for the answer within Crystal's libraries. It had nothing to do with Crystal.
The developer who wrote the helper code for using Crystal first opened a connection to the datasource for the live production database and read that connection information for the report. Next he set that connection information in the report template's PropertyBag, then ran the report. The developer however forgot to close the connection he used to look up the connection info, leaving a memory leak and using up all the connections.
I'm glad you inquired. I forgot to post the resolution here.

J2EE Struts - Database connection failed - help???:(

Hello,
I have built a little web application and it works without any problems. In the next step I tried to add a database connection but I have already worked on it for at least one day and I could not fix the problem with the database connection.
I downloaded the MySQL Server 5.0 and installed it, furthermore I have downloaded the jdbc driver mysql-connector-java-3.1.11.zip and extracted it to the MySQL Server 5.0 directory. Furthermore I have added under system settings - system - etended - system variables the whole path to the driver -> C:\Programme\MySQL\MySQL Server 5.0\mysql-connector-java-3.1.11\mysql-connector-java-3.1.11-bin.jar to the CLASSPATH systemvariable.
Then I have startet the SQL Server 5.0 with mysqld --console from the command line.
Furthermore I have added under Project-Properties-Java Build Path - Libraries - Add External JARs in Eclipse the mysql-connector-java-3.1.11-bin.jar to my Struts WebProject.
To test the whole thing I have added to the existing test-database from mysql a table named owner and wanted to test the database connection in the Action-class with the following statements - I quote the whole execute method of the OwnerAction class:
public ActionForward execute(
                 ActionMapping mapping,
                 ActionForm form,

New database connection failed with oepe

Hi everybody,

The documentation is out of date. The unzip to dropins method is no longer supported. The OEPE zip you downloaded is actually an archived repository. You can follow the instruction for installing using Eclipse Update Manager and point to the downloaded zip instead of the online repository.
I will follow up to get the docs updated.

How to correct close database connection after report generation

Hello
I have problem a with alive database connection after report creation and report closing. How to properly to close connection to database?
Best regards
Edited by: punkers84 on Jun 17, 2011 10:38 AM

that's what I am doing... after viewing the report, I call the close method on the window closing event of the container window. but the connection is still open. I had a lot of other issues with my jdbc driver but after downgrading to an older version those issues are resolved.Only this one is still there! Is there any other way to close the connection (like using dbcontroller or etc.)?

Database Connection Error Cannot create PoolableConnectionFactory

Hello everyone,
Background:
I have a newly installed and configured Ubuntu server running Tomcat5.5 and Mysql 5.0. This server was created in an attempt to migrate from a Red Hat server in a similar configuration, running the exact same webapp. Most of the configuration/classpath differences between the two platforms have been ironed out.
The Problem:
When our webapp trys to connect to the database on localhost, an exception 'java.security.AccessControlException: access denied (java.net.SocketPermission localhost resolve)' is generated.
The server.xml configuration is below:
<Resource name="jdbc/EconDollarsDB"
auth="Container"
type="javax.sql.DataSource"
username="user"
password="pass"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/DBName?autoReconnect=true"
maxActive="20" maxIdle="5"
/>I can connect to the database just fine using the command line client and the same username/password combo. This configuration has been working fine for at least a year on the older server. The only similar problems I have found on the net (meaning the same exception is generated) involve applets and attempts to connect to different hosts. This case involves a webapp, connecting to localhost, using a configuration that is known to work! I am simply baffled.
The following stacktrace is generated:
javax.servlet.ServletException: Database Connection Error
Cannot create PoolableConnectionFactory (Server connection failure during transaction. Due to underlying exception: 'java.security.AccessControlException: access denied (java.net.SocketPermission localhost resolve)'.

Hi,
Its clearly saying the connect permission is missing with the current available policy.
you add the following permisson entry to the <installed JRE>\lib\security\java.policy file.
(e.g) C:\Program Files\Java\j2re1.4.2_08\lib\security\java.policy
permission java.security.AllPermission;
grant{
permission java.security.AllPermission;
If the application is running standalone then the code is allowed uncontrolled access but for webapplicatons running through browser, the security check is performed for the configured JRE.

Database connection in EJB

Hi,
I am using a method for validating Userid and Password in a Session Bean. I could deploy and run it without any errors but the return value is null. The same bean If I am using with <JSP:usebean> tag the return value is correct. That means the database connection is OK. I am giving the code below.
public String validate(String UId,String PWd)throws RemoteException {
try{
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection("jdbc:oracle:oci8:scott/tiger@Everest");
st = conn.createStatement();
String str = "select * from T_CRM_WRK_LCTN where LOGINID='"+UId+"'";
ResultSet rs = st.executeQuery(str);
while(rs.next()){
login = (String) rs.getString("LOGINID");
if(login.equals(UId)){
pass = (String) rs.getString("PASSWORD");
break;
if( (UId.equals(login)) && (PWd.equals(pass)))
flg="Y";
else
flg="N";
st.close();
conn.close();
}catch(Exception e){}
return flg;
Can anyone help me what is the problem. Thanks in advance.

Hi,
Extension to the above problem, the problem is with the Connection. It is not able to establish the connection. Can anyone advise me about the possible reasons.

Database connection remains open after close being called

I am using oracle OC4J as my application server. I am not using connection pool and I am using non-pooled datasource to get connection. The database connection is made at runtime and then closed. I want to test if the users' connection sessions have been killed after they logout the application. But when I checked the table v$session in the database, it shows one connection remaining. I checked my program, the close method has been called. Does anybody know the solution?

Hi Chen,
This is just a suggestion for something to try -- only if you haven't
already tried it, that is!
Try running OC4J in "debug" mode. Here are details on how to do that:

Hope this helps you!
Good Luck,

How can I use SQL TOOLKIT concurrently with Database Connectivity ?

I have installed LabVIEW 6.1 with the Database Connectivity Toolkit and the SQL Compatibility Toolkit (e.g. _SQL folder). I am trying to make the transition from the SQL Toolkit VIs to the Database Connectivity toolkits, but for compatability with existing systems I would like to be able to run the two sets of VIs concurrently (but not in the same app).
When I read into 6.1 a connection VI that I wrote with LabVIEW 6.0 and the SQL toolkit the connection reference type gets changed from a number to type connection (see attachments) . Does compatbility mean that my SQL toolkit VIs are converted to a form compatible with the new ADO ?
Can I use the SQL Toolkit VIs or the Database connectivit
y VIs in the same installation of 6.1 ?
Can I have the SQL Toolkit VIs appear on the functions pallette and function as they did when only the SQL toolkit was installed ?

In response to your #2 below:
Actually it is possible to have the old SQL Toolkit and new Database
connectivity in the same installation of LabVIEW. I have only tried it on
6i, but don't see why it wouldn't work on 6.1. The trick is not to install
the SQL toolkit compatabitily VI's. The old SQL toolkit uses the Intersolve
dll through ODBC while the new Database connectivity uses ADO so it is
possible to use both methods not only in the same LabVIEW install, but it
the same running application. It has been a while since I originally did
this, so I am posting only to mention that it is possible and not exactly
how to do it. If anyone is interested in more details just respond.
