New Microsoft Jdbc Driver For SQL
This property was introduced to JDK 7 in 7u95 and to JDK 6 in 6u121.To enable specific TLS protocols on the client, specify them in a comma-separated list within quotation marks all other supported protocols are then disabled on the client. To use TLS 1.2 by default and disable older protocols, the following configurations need to be performed in the Java Runtime configuration:How to change the protocol version on client sideTo change the default client-side TLS protocol version in the JDK, use the jdk.tls.client.protocols system property. Most of the configurations related to SSL/TLS encryption protocols are found in the Java Runtime Environment and not directly related to the JDBC driver itself.Each version of the JDBC driver supports different versions of the Runtime:Below is a table with the JDK versions and TLS versions supported by Oracle Java implementation:JDK 6 and 7 will use TLS 1.0 by default. Here you will find some information related to SSL/TLS handshake issues with the JDBC driver and how to enable TLS 1.2. Step 1: Configure development environment for Java developmentI've reset to default mssql driver settings and re-downloaded latest driver version, this solved the problem of auth library dependency, thanks!The JDBC URL above is in the format constructed by Bitbucket when connecting Bitbucket to SQL Server and will automatically be updated to a URL compatible with Microsofts driver, with no change required on the administrators part.Microsoft offers a free driver, JDBC Driver 1.0, which is JDBC 3.0 compliant. The Microsoft JDBC Driver for SQL Server has been tested against major application servers such as IBM WebSphere, and SAP NetWeaver.
Intermittent JDBC Connectivity issue – The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Troubleshooting TLS handshake issuesIdentify the version of the Java Runtime Environment being used:Example Java arguments to enable tracing:More detailed information can be found here: This usually happens when connecting from an old server to a newer server, where the older server does not support the newer ciphers, and the newer system has disabled the older ciphers due to security reasons. The client and the server will negotiate and agree on a compatible cipher suite to use, if the two cannot agree on the cipher suite, the connection will return an error.
This error usually occurs when the client and the server have different configurations for the Diffie-Hellman key size range. If the ranges are different, the key generated might have a size that is not accepted by the other machine, leading to this error. The client and the server accept a range of sizes for this key. Error message java.lang.RuntimeException: Could not generate DH keypairDuring the SSL handshake, the client and server will negotiate the cipher suite to use, the KeyExchangeAlgoritm is part of this negotiation, when the algorithm used is Diffie-Hellman, the key used will have a size defined by the server. (JDBC versions prior to 4.2) The connection has been closed.
