We have done the upgrade of the jar file in Adeptia Suite v 6.9.8 because the older jar files were vulnerable and the upgraded jar files that contain various security fixes make them less vulnerable. If you are upgrading to v6.9.8, then the existing MYSQL jar file becomes incompatible and will not work. For this, you need to upgrade existing MYSQL jar files that are compatible with v6.9.8.
This forum post will guide you through the steps that have to be followed in Adeptia Suite to modify the existing DB Info and DB Driver and will also guide you in configuring the new Db Driver and DB Info . We have also attached the latest MYSQL driver-jar that you can download and use while creating the DB Driver.
Below is the essential information that is needed while creating the DB Info and DB Driver for MySQL:
Driver Class: com.mysql.cj.jdbc.Driver
Server URL: jdbc:mysql://DBServerName:3306/DBName?useSSL=false
MySQL JDBC driver: Unzip the attached file and upload the driver in the Configure > Services > Connector> Database Driver.
