This is weird. I'm on a Mac OS X 10.7.5 64-bit host running VirtualBox 4.2.6. I've got a Windows 7 SP1 guest (64-bit) with bridged networking running Microsoft SQL Server Express 2012.
We have benchmarked jTDS against the two most used commercial drivers and of course the Microsoft driver and the JDBC-ODBC bridge, using these benchmarks: i-net software's BenchTest 2.1 for MS SQL Server and JNetDirect's JDBC Performance Benchmark. 3- JDBC Driver for MySQL. 3.1- How to use; 3.2- Some of trouble and how to fix it. 4- JDBC Driver for SQLServer (JTDS). 4.1- How to use (jtds); 4.2- Some of.
I configured SQL Server to use TCP/IP on port 1433, not dynamic ports (setting is blank, not 0). The Windows 7 guest has IPv4 address 192.168.99.132 and Windows Firewall is turned off. I downloaded the Microsoft SQL Server 2012 JDBC driver (sqljdbc4.jar) along with Squirrel SQL client 3.4.0 for both Windows and Mac. When I run Squirrel on the Windows 7 guest OS itself, I can connect to SQL Server just fine via the Microsoft JDBC driver using the machine names of either 'winny', 'localhost', or '192.168.99.132' (JDBC URLs like jdbc:sqlserver://winny SQLEXPRESS:1433;databaseName=vha). However, when I try to connect to SQL Server from Squirrel on the Mac via the IP address 192.168.9.132 (can't resolve 'winny'), I get an exception (see stack trace below). Here's the weird part.
If, from the Mac host, I use the jTDS SQL Server driver (version 1.2.7 because I'm using JDK6, so can't use jTDS 1.3.0 - that version is JDK7 only), I connect right away with both of the JDBC URLs jdbc:jtds:sqlserver://192.168.99.132:1433/vha;instance=SQLEXPRESS or jdbc:jtds:sqlserver://192.168.99.132:1433/vha. Any ideas why the Microsoft driver fails but jTDS succeeds from a remote host?
And yes, I've tried the Microsoft URL with and without the instance name.
This page describes how to change from using jTDS to using the Microsoft SQL Server JDBC driver to access Microsoft SQL Server. What do I have to do? Bamboo will try to automatically migrate the database configuration during upgrade.
If that fails, the system will lock on startup. To resolve this, you need to manually update the driver class and URL. How to proceed In the Bamboo server home directory, bamboo.cfg.xml must be edited to change the JDBC driver and URL.
Jdbc Jtds Sqlserver
The existing configuration should look similar to this. Net.sourceforge.jtds.jdbc.Driver PASSWORD jdbc:jtds:sqlserver://127.0.0.1:1433/Bamboo bamboouser com.atlassian.bamboo.hibernate.SQLServerIntlDialect The JDBC URL above is in the format constructed by Bamboo when Connecting to SQL Server and will automatically be updated to a URL compatible with Microsoft's driver, with no change required on the administrator's part. If the URL contains additional properties, such as domain=, it will need to be manually updated. To use Microsoft's SQL Server driver, the settings above would be updated to this. Com.microsoft.sqlserver.jdbc.SQLServerDriver yourpassword jdbc:sqlserver://localhost:1433;databaseName=bamboo username com.atlassian.bamboo.hibernate.SQLServerIntlDialect The exact values to use in the new URL are beyond the scope of this documentation; they must be chosen based on the jTDS settings they are replacing. Additional Information for the curious The new JDBC driver class is: com.microsoft.sqlserver.jdbc.SQLServerDriver The JDBC URL format for the jTDS driver is documented on SourceForge at.
The JDBC URL format for Microsoft's SQL Server driver is documented on MSDN at, with documentation for additional properties at. Why change drivers? Recent releases of Hibernate, which Bamboo uses to simplify its persistence layer, have introduced a requirement that the JDBC drivers and connection pools used be JDBC4-compliant. JDBC4 was introduced with Java 6. The jTDS driver used by releases prior to Bamboo Server 6.0 is a JDBC3 driver, compatible with Java 1.3, and therefore cannot be used with newer versions of Hibernate.
While jTDS 1.3.0 and 1.3.1 claim to implement JDBC4, and JDBC4.1, they actually don't. The new methods have been 'implemented', but their implementations are all throw new AbstractMethodError, which means they can't actually be used. (See an example.) Since jTDS 1.3.1 does not provide a functioning JDBC4 implementation, the decision was made to replace jTDS with Microsoft's own SQL Server driver. Microsoft's driver is actively maintained, where jTDS hasn't been updated since 2014 (and prior to the small round of updates done in 2014 it hadn't been updated for multiple years). Microsoft offers a full JDBC4.2 (Java 8) driver and supports all the features of SQL Server, including SQL Server 2016.
Download Jtds Driver
Bamboo attempts to automatically update jTDS JDBC URLs to values compatible with Microsoft's JDBC driver. However, for installations using custom JDBC URLs–for example, to use domain authentication–such automatic updating is not possible; the URL, which was manually entered, must be manually updated.
