CA Forum: Data Connectivity and SQL
Hi, I am having problem with conecting Crystal Report XI to the MYSQL Server. I am using Mysql Connector/ODBC 3.51. I configured ODBC connection . Once i connect to MYSQL server thru Crystal Rpeort Everything works fine but after 5-10 minutes if i refresh the report I get following error.
"Failed to retrieve data from the database"DetailsHY000:[MySQL][ODBC 3.51 driver][mysqld-4.1.22-standard-log][MySQl server has gone away[Database vendor code :2006] and if i log off and relog on to database everything works fine like for another 5-10 minutes and after that same ERROR But if i use MYSQL Query Browser to connect to the database. I don't have any problem like that. Can please explain any reason for that.....Thanks

I'd guess that you're timing out or exceeding the number of connections.

DAS Can't connect to mySQL ODBC

Using: HPS 8.3 Sun Solaris 8 I've created a BQY in Intelligence Explorer that connects using mySQL ODBC in Windows XP and wanted to publish it to the web, but I needed to publish the OCE to the server and set it up with DAS. Here are the steps I took 1. Installed the mysql connector odbc 3.51.12 sun solaris2.8 sparc 64bit ODBC in Solaris. 2. Created an odbc.ini file in Solaris with my mySQL connection settings in the home directory of the user running the services. I even made a copy of it in the $BP_HOME directory. 3. Added the library path for my ODBC library to all my scripts. 4. Added the data source using the service config tool. 5. Restarted services 6. published the OCE and BQY When I access the BQY using the plug-in, it gives me "Server Error [2009]; Internal Error Detected in Data Access Service" When I access it using the thin-client (iHTML), it gives me: "An Intelligence Service error has occurred.-Failed to acquire requested service" What else needs to be done? I tried some the other suggestions to no avail: --added the library path to the LD_PRELOAD variable in the $BP_HOME/bin/services.sh script Also, I noticed that when I ran ServiceConfig.sh, there were no data sources to pick from the dropdown. Anyone know how to make that active so I can just PICK the connection to use?

I'd strongly recommend that you take all that JDBC code out of your JSP. Put it into a class that you can test on the command line. Once you have it working, you can use it to get at data and pass it along to your JSP for display.
I'd also recommend that you not use scriptlets and learn JSTL right away. MVC separation suggests that putting Java code in a JSP is a very bad idea.

"stack overflow" when trying to connect with Oracle ODBC

Hi,
I'm trying to connect to Oracle DB (8.1.7.3.0) from WinNT 4.0 SP6 with Oracle ODBC driver 8.0.6.6.0. I've been trying to connect with "Oracle ODBC Test" and with "MS Query". In either way I end up with Dr. Watson reporting about "stack overflow". Before starting to upgrade ODBC driver I wanted to ask - should these versions of driver and DB work together at all (even unofficially)? Or may I be missing some other thing? Any hints, ideas are welcome.
Regards,
Madis Priilinn

Thank You for replying, Justin!
Yes, I can connect successfully to the database through other tools - at the moment I tried SQL*Plus, Net8 Easy Config and Schema Manager.
The Oracle client in the NT machine is 8.0.5.0.0. And unfortunately I do not know anything about the Oracle installation on this machine and at the moment I don't have that person near me too whom to ask also. But I think the installation was ok, because the connection through ODBC was working before the DB upgrade as far as I understood (sorry, again at the moment I don't know what was the previous version of DB. I will ask that information as soon as possible).
The main problem that bothers me at the moment is that I can't install 8.1.* series OraODBC driver with 8.0.5.0.0 Oracle Installer. I managed to install 8.0.6.6.0 version of the driver, but not the newer ones. As far as I've understood I have to upgrade the whole Oracle in the NT machine to upgrade that installer. Am I correct?

Problem in establishing connection with mysql 5.0

Hi,
I am using JCAPS 5.1. I tried to insert data to mysql database table.
But i got following error
java.sql.SQLException: Error in allocating a connection. Cause:
Physical Connection doesn't exist.
My intention is to read file in which data are comma seperated and to
populate those values to a mysql 5.0 database table.
Sample DATA in file [test.txt]
111,gg,23,MFG
112,hh,24,MFG
113,ii,25,RETAIL
114,jj,26,IT
Database table: employee
eno,ename,eage,edept
While creating JDBC OTD there is no problem in establishing connection with database. But after deploying i got above error.
I have used Mysql 5.0 Connector/J JDBC driver. Added JDBC driver jar files to following directories as required.
1) C:\JavaCAPS51\logicalhost\is\lib
2)C:\JavaCAPS51\logicalhost\is\domains\test\lib
Steps i have followed as per JDBC-ODBC -eway user guide doc.
1) Created USerDefined OTD and added necessary fields
2) Created JDBC OTD.
3) Created JAVA collaboration and do business process for inserting
4) Mapped all components by creating in Connectivity MAp
5) created necessary external systems in envrionment explorer.[JDBC External System and File External System]
6)Created Deployment profile
5) Deployed it.
After deploying it gives error as
java.sql.SQLException: Error in allocating a connection. Cause: Physical Connection doesn't exist
Please let me know the solution for problem.

In the environment definition,
-> External Application JDBC
-> Properties
-> Outbound JDBC Connection
You have the database URL in the "DriverProperties" field
Valid URL would be : jdbc:mysql://localhost:3306/caps
!! The doc says that this field is optional !! Seems to be an error in the doc:
Hope this helps

A Connector/ ODBC 3.51.28 - Add Data Source Name window opens up which have the DSN connection details (DSN Name , Server , user , password , database).
I put all the default details
After this i got a error message saying that
Adobe LiveCycle Designer ES has encountered a problem and needs to

Crystal Report on Universe with MySQL ODBC

Hi
I created a report with Crystal reports by using a Universe based on MySQL ODBC. In my local (Windows XP) installed Report Designer everything is running fine. I'm also able to publish this report to my BOE, based on RHEL.
If I will refresh my report on InfoView, database credential are required, but my credential are not accepted. I only become a error message: Failed to open the connection
If I use Webi with the same universe and the same connection, everything is fine.
I have also change the ODBC version, but no other result.
Any idea, where I can trace this connection?
Versions:
Crystal Reports 2008 (12.0.0.683)
Business Objects Enterprise 3.0 (12.0.0.683)
MySQL ODBC 3.51.27 and 5.1.5
Thanks a lot
Christoph

Hi,
thank you very much for reply.
I think you got it. We have the goal to create a report that can be printed and is top-gloss-report for management ; ) One query would not be able to include all that stuff. It is very different.
So we created 7 different queries in SAP BW Query Designer and we want to put them together in BO Crystal Reports.
All Queries work with input variable for period and year. These input variables are used in the columns of the queries for calculating the key figures.
So, if we put these queries together into Crystal Reports, we should actually use "replacement path" for variables. But the sap.help says, that isn't doable.

Connecting with mysql

hello
how can i create a connection to mysql and postgresql databases in jdbc. without using odbc.
thanks.

You need to use a different driver. I assume you're using the jdbc-odbc bridge driver.
For mysql, get the mm.mysql driver at http://mmmysql.sourceforge.net/
For postgresql, go to http://jdbc.postgresql.org/
I've only used the mysql driver, so I don't know the details of how to use the postgresql one.
In general, you will have to do the following:
1. download the jar file and put it in your classpath
2. change the connection url string to conform with the format in the driver documentation.

How to connect to JDBC with Mysql Connector

I think you should give a username and password. How can it look up a password without a username? Better GRANT the right permissions, too.
Read the MySQL docs a bit more closely. Your path isn't the way to go.

Connectivity with MySQL in Windows

How can I connect JSP with MySQL in Windows?
 I Tried out the following code but It did not work
 Class.forName("org.gjt.mm.mysql.Driver");
 Connection cn = DriverManager.getConnection("jdbc:mysql:///test");


I think you missed the IP address for your MySQL server machine.
 If it's on the same computer, try this:
 jdbc:mysql://localhost/test

The MySQl ODBC driver requires an ODBC Driver Manager (libodbc.so.2). So please make sure you first install an ODBC Driver manager (for example unixODBC Driver Manager release 2.3) using an RPM or compile it from the soiurce files (www.unixODBC.org).

Create a simple connection with mysql

hello
my name is edvanio i am from brazil.
i'd like to connect one program in Java with mysql for insert, delete and update one simple base ex. teste with nome and fone.
thank , bye

here's a couple of sites
http://www.javacoding.net/articles/technical/java-mysql.html
http://www.developer.com/java/data/article.php/3417381
I recently installed MySQL (just to see if I could get a working program to run)
these were the steps
1. downloaded MySQL
2. downloaded the connector file
3. unzipped/installed MySQL
4. unzipped the connector file
mysql-connector-java-3.0.17-ga-bin.jar
copied the jar file into this directory
C:\Program Files\Java\jdk1.5.0_03\jre\lib\ext
5. opened MySQL, using the code from Gamelan
create the db JunkDB
created the user, permissions, password
6. combined the code from both sites (code follows)
and it worked OK
import java.sql.*;
class MySQL_Test
public MySQL_Test() throws Exception
    testDriver();

Create database connection with Mysql

Hi, all:
inside JDeveloper, i try to create a database connection for Mysql (third party
JDBC driver). I input all needed parameters into
JDeveloper database connection dialog, and test connection, the error message
says 'Unable to find driver org.gjt.mm.mysql.Driver". The jar file contains driver
is listed in system classpath, and Mysql and MM-Mysql JDBC driver are tested with
other applications and there is no problem.
So, what i should do to create such a connection ??
Any help will be appreciated. thank you in advance.
kevin.

The connectio URL could look like this:
(leave the User-, Password-, and Role-fields, in the tab before, empty)
Java Class Name: org.gjt.mm.mysql.Driver
URL: jdbc:mysql://localhost:3306/test?ultradevhack=true&?user=myuser&?password=mypassword

Jakarta-tomcat-3.3.2 connection with mysql-4.1.12a-win32

how do i connect to mysql using tomcat?
i've set the class path = ".;D:\j2sdk1.4.2_08\jre\lib\ext\mysql-connector-java-3.1.10-bin.jar;"
without quotes
i've copy the mysql-connector-java mysql-connector-java-3.1.10-bin.jar into the mentioned directory = "D:\j2sdk1.4.2_08\jre\lib\ext\"
and my computer's mysql 's service is starting since my computer restart [i've checked it by right click desktop toolbar->Task Manager->Processes->mysqld-nt.exe..
and i've used the code from :
http://www.stardeveloper.com/articles/display.html?article=2003090201&page=4
to test if my connection is active, my JdbcExample1.java file is located at D:\jakarta-tomcat-3.3.2\webapps\ROOT\WEB-INF\classes\com\example, so my source code is :
package com.example;
import java.sql.*;
public class JdbcExample1 {

Connection con = null;
try {

con = DriverManager.getConnection("jdbc:mysql:///test", "root", "nothing");
if(!con.isClosed())
System.out.println("Successfully connected to MySQL server...");
} catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
} finally {
try {
if(con != null)
con.close();
} catch(SQLException e) {}

what have i missed out? anyone can u please help me? is my coding or setting in-accurate? thanks for reviewing my topics too

I'm not sure why you have mentioned Tomcat, but you need to run the class with something like:
java -classpath .;D:\j2sdk1.4.2_08\jre\lib\ext\mysql-connector-java-3.1.10-bin.jar com.example.JdbcExample1If you've correctly set the CLASSPATH environment variable then you can leave out the -classpath command line argument. Notice that you must specify the package of the class too.
To compile this all correctly, you should do something like:
mkdir classes
javac -d classes JdbcExample1.javaand then run with
java -classpath classes;D:\j2sdk1.4.2_08\jre\lib\ext\mysql-connector-java-3.1.10-bin.jar com.example.JdbcExample1
