FAN and PHP

Hi,

I'm trying to set up my PHP Applications with FAN Support. After about a week of unsuccessful testing I am really stuck and would like to ask here for further

help. This is my configuration:

OCI8 Version = 2.0.8

PHP Version = 5.5.23

Oracle DB Version = 11.2.0.3

Oracle Client Version = 11.2.0.3

oci8.events = On

I am using a new service with AQ notification = on

When I shutdown one instance (killing pmon or shutdown abort) my application gets:

ORA-12520: TNS:listener could not find available handler for requested type of server

I thought that it should switch the connection to a surviving instance. But it seems that it caches the connect information to the local instance/local listener but

as this listener doesn't have informationen about the killed instance my application receives ora-12520

Does someone have further hints on how to fix that problem? Thanks in advance!
