And both client installation have Oracle11g database details included in tnsnames.ora. Now I have 10g &11g both installations on my machine. " I already installed SQL client 11.2.0.3.0 on my machine.

"2) So I don't need to have 11g client on my machine. net side code changes?ĥ)Also, is it really oracle client required on my machine? Now If I upgrade my to v-2.112.3.0 then from which version of tnsname.ora file it will take my database?Īlso if I use this updated version, then is there any way to get better performance with this new by using any.
