Have a workstation that has several oracle clients (10.1.5, 10.2, 11.2). Also using the TNS_ADMIN environment variable. You can see these under the Connect Using: drop down, however the Database drop down does not have any of the choices that are in the tnsnames.ora file (same file others are using successfully) AND the check boxes for SQLNET Editor / TNSNames.Editor have red X’s by them instead of the green check marks.
I uninstalled Toad (18.104.22.168) and reinstalled no difference. Tried changing the TNS_ADMIN entry from C:\Oracle\product\11.2.0\client_2\network\admin, to C:\Oracle\product\10.2.0\client_2\network\admin, restarted TOAD, no difference.
I have checked across all the installed Oracle ‘products’ and the tnsnames.ora is the same with multiple entries.
Not sure why the Database list isn’t populating and the other two checkboxes have the red X’s…
