Hello,
We created a shared db link, it works fine to connect to another database.
The problem is, when client opened many sessions at same time (for example, simulation of 30 or so users all using the DBLINK at the same time) , we get error: ORA-12516:TNS:listener could not find available handler with matching protocol stack
database is 12.1.0.2 in windows server.
any idea?
Thank you very much!
