Hi, I need to find a way to change the jdbc password dynamically every quarter and at runtime without lost active connection already in the pool (obviously without restert services, JVM).
You can change it via wlst like below but I don't think WITHOUT server restart all changes will take effect. Dynamic changes usually dont need a restart but if its an non-dynamic then yes you have to restart
serverConfig()
edit()
cd('JDBCSystemResources/JDBC Data Source-0/JDBCResource/JDBC DataSource-0/JDBCDriverParams/JDBC Data Source-0')
startEdit()
cmo.setPassword('*****')
activate()
Activating all your changes, this may take a while ... The edit lock associated with this edit session is released once the activation is completed.
If you get any non-dynamic ds entries password changed then you must restart the server to make this effective.
