Hmm...my first thought is that this could be an OS/network configuration limitation on
the client side? Though it does seem odd to raise an ORA-12154, after many successful
connections....
What OS is the client?

Dear Gurus,
We are getting the following error if we try to create more than 256 connections from
the same client. The problem is easily reproducible bt writing simple java program and
keep creating connections(do not close it).
Did anyone encounter this kind of issue and how did you solve it?
Exception in thread "main" java.sql.SQLException: ORA-12154: TNS:could not resolve
service name
