Can you show us all Oracle clients (both 32 and 64-bit) that are installed in the new PC? And what clients are picked up in the combo box of SQL Nav logon dialog? You can also click the … button on the right of the combo box to show more info of the clients.
In additional, the following information is helpful:
Do you have TNS_ADMIN set in system/user environment variables?
Do you have TNS_ADMIN set in registry under each Oracle client? (e.g., HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraClient11g_home1: TNS_ADMIN)
Lastly, 7.3 beta works better in terms of making connection in complex Oracle client environment. You can have a try if possible.
Just dowloaded the new beta version. The DBA was able to install this one. We will work with this one and wait for the commercial release. Big problem if the release runs out and a new beta version is not published before the end date.
Our DBA managed to install his pc (after a lot of tries), but on mine, nothing works. We tried version 6.7 and 7.3. We always get the same error then shown above.
I’m so sorry about your situation, I have tested a few case about SQLNav logon different oracle client in this morning, the version of 7.2 and 7.3beta are work fine.
Could you help me confirm the “tnsnames.ora” file have exist in “ORACLE_HOME\network\admin” ? if you pc have installed a few oracle clients, make sure that each of the clients have contained the tnsnames.ora file.
Martin, can you add the following entries to your existing tnsnames.ora (remember to replace the ip_adress with your real ip) and test these new entries from SQLNav logon window?
