RE: After 256 connections : ORA-12154

Brad, Thanks for your response.

If you are trying to open that many connections from a single client you should start to look at connection manager to pool these connections of at least recode your app to share connections.

We are getting this error when the application is trying initialize the connection pool.

Anytime you see a number like 256 it is likely you are hitting some limit.

My guess is you are running out of memory in your application on that client.

If you are trying to open that many connections from a single client you should start to look at connection manager to pool these connections of at least recode your app to share connections.

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
