I just spent most of my day troubleshooting this problem.
Click “New Connection”
Enter Direct Connection: **Host, Port, SID **(tried connecting by host name or IP)
Connect Using: OraClient11g_home1 (also tried “Instant client 184.108.40.206.0”)
[ FREEZE ]
Troubleshooting i’ve done:
I am able to telnet to that host:port
netstat -a tells me that the connection to that host:port is ESTABLISHED (by TOAD)
I profiled using Process Monitor, and i can see that TCP Send from: MyMachine:52302 > host.domain.com:port is a SUCCESS
i am also able to connect instantly using Oracle Sql Developer
- more developers at this location have this same exact problem.
- some developers are able to connect no problem.
i am using Toad for Oracle 11.0, but i also installed 12.0 trial version to get the same problem
**It appears to me that Toad is doing something after establishing a TCP connection on the UI thread, but i haven’t been able to figure out what that is… **
