Today we notice One of our 2 node RAC db Local listener parameter has auto-changed .
Application is behind firewall and for them both ports 2221(local listener) and Scan listener port(1621) is opened. So if local listener port changes to 1521, they are not able to access application.
Local_listener value we seted 2221 and it got automatically changed to 1521.
After checking all db and Cluster logfile did not find any clue how it got changed . so we raised Sr with oracle. oracle confirm this is bug .
Bug 11772838 - oraagent modifies LOCAL_LISTENER with an incorrect value, when the parameter was set in spfile (Doc ID 11772838.8)
