Specifying the JDBC driver
The application server requires a JDBC driver to enable communication with the database. The JDBC driver that you provide to the deployment toolkit depends on the database management system to use with the deployment.
Procedure
Locate the JDBC driver for your database management system.
If you are using PostgreSQL, download the latest driver from jdbc.postgresql.org.
If you are using Db2®, locate the IBM\SQLLIB\java\db2jcc4.jar file.
If you are using SQL Server, download the latest version of the Microsoft JDBC Driver for SQL Server that's compatible with your system from https://learn.microsoft.com/sql/connect/jdbc/download-microsoft-jdbc-driver-for-sql-server. Extract the contents of the download, and locate the file whose name matches the pattern mssql-jdbc-x.y.z.jre11.jar.
Copy the relevant driver file for your database management system to the toolkit\configuration\environment\common\jdbc-drivers directory.
Note: Ensure that the user you use to run the deployment commands has write permissions for the JDBC jar file.
