PLSQL developer slow startup when in VPN

[JohnAround]

Hi,
we have the tnsnames.ora and sqlnet.ora in a shared samba directory. When starting PL/SQL developer, it takes a long time.
Checking with wireshark, it seems PL/SQL developer is checking sqlnet.ora many many times.
I am using 15.0.4.2064 currently.

We will look into this and optimize if possible. It can also be that the Oracle Client Library is performing these operations, in which case it is most likely not possible to optimize this. We will find out and I will post the results here.

Hello,
we are facing the same problem on version 16.0.3 (64 bit).

Additionally many crashes of PL/SQL-Developer when connects via VPN.

Same setup: tnsnames.ora and Oracle-client on shared samba directory.

The PL/SQL Developer startup procedure only accesses the sqlnet.ora file once. The other file access operations are probably caused by the Oracle Client during initialization. You could verify this by starting sqlplus.exe from the same Oracle Client, with the same TNS_ADMIN environment.
