I have a OC4J application running in oracle application server 10g. It currently connects to an 11Gr2 database using an oracle thin jdbc connection. I'm trying to connect the same app to a 12C data again using the thin jdbc connection with no success. this is the error.
Unable to establish connection for one or more OC4J instances in the group. Below are the results for each OC4J instance.
"my OC4J: on "my site" - Failed due to error: "Exception occurred testing connection. Exception: java.sql.SQLException: Io exception: Got minus one from a read call."
I'm assuming it's due to a jdbc version issue. I can connect via sqldeveloper to both dbs. Any thoughts with updating the jdbc on the application server side would be appreciated. thanks
