如何使用 java 连接到具有 TLS 版本 1.2 的 DB2 数据库？

Question

I see we have different parameters for connecting to the DB2 database like,

sslConnection=true
sslTrustStoreLocation=/opt/db211.5/sslkey_b2biqarhlmk9/key.jks
sslTrustStorePassword=password

This parameter can be passed to the JDBC url for DB2, and this establishes the SSL connection between application and DB2 database. However, is there a way by which we can restrict the TLS version for the connection? How to specify the exact TLS version, say TLSv1.2 for this connection?

Thanks Dev

Answer 1

Add the sslVersion=TLSv1.2; property to your URL.
This prevents connections to non-TLSv12 enabled Db2 LUW databases or enforce TLSv1.2 mode if, say, your server supports both modes with SSL_VERSIONS dbm cfg set to TLSV12,TLSV1 .
