we have both oracle 8 and 8i versions of databases.
oracle 8.0 version is in sun platform.
oracle 8i is in windows NT platform.
Oracle 8.0 version databases are to be connected through firewall.
Previously i have to connect to only one database through firewall and i happen to give the ip address of the firewall machine which automatically finds my database when i configure through net8 assitant in my NT machine.
But now i have the second database in different host which has to be connected through the firewall and i am not able to connect to it from my NT machine.
I am able to connect to different databases from the sun machines.
But i have problem configuring from nt machines.
Is there any specific way i have to configure my system if i have to connect through firewall.
I have little knowledge about connection manager. Does it helps me in anyway. If yes let me know in detail how it could help me and how could i congifure it.
I hope i have explained in such way that you could understand whats the exact problem that i am facing. If not please let me know .
Well the point of a firewall is so connections can't get through. Before any Oracle configuration you have to make sure that there's a way for your machines to talk to each other. If that means going through a proxy or poking a hole in the firewall or whatever, if they can't somehow get through the firewall they'll never be able to talk :)
Once that's settled you can try to configure the databases. If it's just a hole in the firewall for the port the listeners use that would be easiest, if you have to go through a proxy you might have to set up port forwarding or something.
Check notes #62528.1 and #1030314.6 on Metalink for Connection Manager. It explains it's use, setup and configuration. Connection Manager is available only on Enterprise Edition. You can custom install this on the client side.
