We have windows based application developed on PowerBuilder 2017 and which connects to SQL server 2014. Recently, server protocol upgraded to tls 1.2. From then, application can not connect to database server and it throws SSL hand shake failed error. Please advise.

We have upgraded Application to PB2022 and updated connection string to OLEDB driver. but it throws DB code 18456. We are able to connect SQL server from other .net app and SSMS so we are good with connectivity from ID but got an error from PowerBuilder app.

Hi Susan;

The current Microsoft DB Client driver for SS is now ""MSOLEDBSQL". MS recommends that you start using this DB Client vs older SS DB drivers going forward. PB 2022 supports this latest MS SS DB Client via the setting ... SQLCA.DBMS = "MSO" // short for MSOLEDBSQL

HTH

Hi Susan,

if you use ODBC, you will be fine if you install a newer ODBC Driver for SQL Server that supports TLS 1.2.

Eventually you have to set TrustServerCertificate in the ConnectionString, depending on the "quality" of your certificates.

As Roland and John said, upgrade PowerBuilder to PB 2022 R3 and use the MSOLEDBSQL driver if you want to use TLS 1.2.

SQL Server 2014 support end date was Jul 9, 2019. PowerBuilder 2017 is also out of support. You should upgrade both.

I believe TLS 1.2 for SQL Server was not supported in PowerBuilder until version 2019 R3.
