 Hello 

 

Hope you dont mind in clearing my doubt. i will explain issue below.please go through when u r free and respond.

 

 

ISSUE:

We are restarting our server once in two days. otherwise DB is getting down.Please guide me how to resolve this.

 

I Checked the  last known stag in Enterprise Manager when Database was down .

 

There in the Alertfile it is showing "Failed to connect to database: ORA-12519: TNS:no appropriate service handler found (DBD ERROR: OCIServerAttach)."

 

When I restart the server it will work fine for another one day and again same problem persists.

 

This problem started recently after we created a new pfile and spfile for database start up.

Howdy, Stranger!
