experts - I have a following question with regards to some of applications in here. Sorry - I am just learning java - so kindly be patient. We have several applications here using weblogic app server - mostly on 9.1 version. They use dataserver connections from weblogic.
Now if dataserver is rebooted - goal is thatapplications should automatically reconnect. But I am not sure how to make this happen. DBA's are scheduling a reboot 2 times a week for some of their work - and I want that as soon as dataserver is up - applications shoudl just reconnect. Is it something I need to write code ? or is it something automatically built in weblogic. How should I do it is my question. appreciate the help

I think you are going a bit wrong about this. You should also close the weblogic servers before you close the database servers. Anyhow if any requests come to the weblogic server during when the database is down you'll get into all sorts of trouble and errors because there is no database available.
I would do this: 1. close the weblogic webserver 1 minute before the scheduled reboot on the database server(s) 2. close the database server 3. start the database server 4. start the weblogic webserver
You could use ping on the database server to see when it is up again and then start the webserver and it will connect to the database.
