I need to display the parameter and status of DB for listener and Read Only.

I know those value could be get from command line , but could we get the values of Listener and Read only by SQL/PlSQL? So I can get it through the query of DB.

Thanks,

I hope to check if the value for listener and read only can be retrieved from table, so I can get it from SQL or PL/SQL through JDBC.

From lsnrctl status, we can show the listener , but it is a little difficult to integrate it in java code. For Read only, I only know Alter Tablespace xxx Read Only, I don't know how we can check if a table space is read only or not by SQL or unix command.

Thanks,

Thanks, dba_tabelspaces is good enough for me to get the Read Only . Is there database table store listener information too?

Oracle RDBMS does not know or care if listener exists or not.

Thanks, but I realized that there are multiple table spaces and could have different status for each table spaces (online, read only) . It is not what I need, sorry for providing the wrong information.

I need the read only status for DB (like through ALTER DATABASE OPEN READ ONLY) , do we have the table for DB read only information ?

Thanks,
