upgrade from 9.14 to 9.20
We are facing issue after 9.22 upgrade and not able to start the services, please suggest us some solution if any of you faced the similar error.
com.kintana.ismp.bean.actions.ServerModeAction, wrn, java.sql.SQLException: Listener refused the connection with the following error:
ORA-12516, TNS:listener could not find available handler with matching protocol stack
The Connection descriptor used by the client
Re: upgrade from 9.14 to 9.20
This error occurs when the configured maximum number of PROCESSES limitation is reached. The service handlers for the TNS listener become "Blocked" and no new connections can be made.
Increase the value of the PROCESSES parameter in your database and see if the issue gets resolved.
Hope this helps.
