Not able to connect to Teradata using jdbc - java

I am trying to connect to Teradata using jdbc. My application is running in JDK 1.4.
The url i am using is "jdbc:teradata:///TMODE=ANSI,CHARSET=UTF8";
I get "No suitable driver error" when i try to run using JDK 1.4.
However, I am able to run my app using JDK 1.7 with the same url.
I have both terajdbc4.jar and tdgssconfig.jar in my Netbeans libraries.

You probably use the wrong version of either Java, Teradata JDBC or Teradata Utilities (TTU).
Take a look here, what is compatible with what: Compatibility
The matrix is part of this reference which holds information how to use JDBC with different Application Server like JBoss, Tomcat, WebSphere, ColdFusion, WebLogic, SAP etc.

Error connecting to memsql with mysql J connector

I have memsql server version 6.7. I am able to connect to it using mysql java connector version 5.1.47 from my spring boot application.
But when i upgrade connector version to 8.0.16 I get below error -
Caused by: java.sql.SQLException: Unknown system variable 'performance_schema'
Ran query SHOW VARIABLES; on my memsql instance and I do not see system variable 'performance_schema'.
Can i change datasource.url string to ignore this variable? Any other latest version of driver is supported?
If your concern is the security issue in the 8.0.15 mysql driver you could use the mariaDb drivers instead. We generally recommend folks use them with MemSQL:
https://docs.memsql.com/client-downloads/
MySQL 8 made a number of breaking changes (i.e., you will have issues with MySQL 8 drivers connecting to older versions of MySQL as well : https://bugs.mysql.com/bug.php?id=90994)
From https://github.com/spring-projects/spring-boot/issues/17090:
A relevant change in Spring Boot 2.1.5 would appear to be that it upgraded MySQL's Java connector from 8.0.15 to 8.0.16. The 8.0.x driver should be compatible with MySQL 5.6, 5.7, and 8.0 so this would either appear to be a problem with your configuration or, probably more likely, a regression in the driver. If you would like to pursue this, I would recommend asking for some help on the MySQL forums and providing sufficient information to allow someone to reproduce the problem.
Try version 8.0.15 to see if that works better.

WebLogic Upgrade Causes JDBC DataSource to fail

My company uses a commercial web tool that we host on-site. It uses a Java backend and runs out of WebLogic. We recently did an upgrade to the tool and part of it was an upgrade from WebLogic 12.1.1 to 12.1.3. After the upgrade we noticed that we started getting consistent errors when it tried to do certain things.
From WebLogic's log file:
java.sql.SqlException: [FMWGEN][SQLServer JDBC Driver]Object has been closed.
The database is SQL Server 2012 Enterprise Edition (SP3) and running on a Windows Server 2012 box. It appears to only happen when the tool does a SELECT statement against a synonym to another SQL box. If I make that synonym point to something locally, it works. I have verified that Enable XA Transactions is still enabled (as it was before the upgrade).
Sadly, I am unable to turn to the company of the tool since our use of synonyms is not supported with there system. Nothing changed with the database server - what could the issue be?

Which version of oracle thin driver to use with application deployed on Websphere 7.0

I am trying to connect to my 10g database using oracle driver in ojdbc14.jar. My webservice is running on Websphere 7.0 which uses Jre 1.6.
When I am trying to access the Webservice, I am getting the following exception.
"JDBC driver name : Oracle JDBC driver
JDBC driver version : 10.2.0.4.0
JDBC driver specification level : 10.2
Oracle does not support the use of version 10 of their JDBC driver with the version of the Java runtime
environment that is used by the application server."
Please let me know which version of oracle thin driver I have to use to connect to my 10g Database using Websphere 7.0.
If Oracle 10g ships with a JDBC driver called ojdbc6.jar, then you should use it instead of ojdbc14.jar.
Otherwise, you can use the Oracle 11g JDBC driver (I know, for sure, that it ships with ojdbc16.jar). Unless otherwise noted, Oracle's JDBC drivers are backward compatible.
You said following (in the last line of your original question):
"Please let me know which version of oracle thin driver I have to use to connect to my 10g Database using Websphere 7.0.".
So, please note that you don't have to worry about the version of driver to connect to your database.
That's so because "Oracle 10g Database" is by default shipped with the RIGHT driver to connect to it.
Apart from this, which version of JDK are you using in WebSphere 7 ?

where do i download jdbc driver for DB2 8.1?

I'm planing to develop a web application with spring framework. I am using DB2 8.1 as database ,but did not find any JDBC driver for accessing DB2 from java.
For the most recent JDBC drivers, you can get them from http://www-01.ibm.com/support/docview.wss?uid=swg21363866
The drivers for 8.1 are not there, but the names are there. You can use any from the 9.1 version to connect to the 8.2 server.

Using MySQL 3.x and 5.x simultaneously from Java

How can I use MySQL 3.x and MySQL 5.x simultaneously from my Java application if the two versions need different versions of JDBC drivers but the driver class name is the same?
For MySQL 3.x I downloaded MySQL Connector/J 3.0.17 and for MySQL 5.x I have MySQL Connector/J 5.1.12. How can I use them both?
First check whether (as mentioned by #DaveHowes +1) you can use JDBC driver for v5 with DB v3. It probably works. In this case you have no problem.
If it does not work you have to use separate class loaders for 2 connectors to 2 different DBs. So, neither v5 nor v3 JDBC driver will not be in "regular" classpath of your application. Instead you should create some kind of wrapper that will instantiate its own UrlClassLoader: and start driver. The mentioned collector should expose API that allows you to perform JDBC query. I hope this will work. All this if you are using pure JDBC. If you are using some kind of tools (e.g. Hibernate, iBatis etc.) I wish you good luck :) and suggest to ask more specific question that mentions tool you are using.
