TNS-12602

TNS: Connection Pooling limit reached

Cause

The operation failed because maximum active current connections has been reached. It may not be a real error when the Connection Pooling feature is enabled. It is possible that the application later reissues the operation and successfully grabs the connection pool slot and proceeds.


Action

This is an internal error. Enable tracing and attempt to repeat the error. If it occurs again, contact Oracle Customer Support.
