If the database password has been changed, some ConnectAll services may fail to start due to the db.properties file still referencing the previous password.
First, you will need to locate your ConnectAll Core installation directory.
For Linux this is often /opt/ConnectALL/Core
For Windows you can discover the location by opening a File Explorer window and typing %CONNECTALL_HOME% in the bar as shown below:
Navigate to the conf directory
Make a copy of the db.properties file to a different location such as /root in Linux or the Desktop if you are using Windows
Open the db.properties file in an editor
Update the jdbc.pwd line and type your new password in plain text
Save the file
Restart the Core first and then the rest of the ConnectAll services for your version as documented here:
If the password is not encrypted in the db.properties file after the services have started up, then you can go into the DB Settings and set the password through the UI to encrypt the password.
