Hello,
I am trying to get OCILib (http://orclib.sourceforge.net/), a free Oracle
library, running on MacOSX. I have built the library from source and
successfully run a test class via the terminal containing the example code in
the OCILib documentation. As an experiment I have created a Cocoa app in XCode
and dumped the code in the test class in the App delegate's
applicationDidFinishLaunching method.
However when I run the app from within XCode I get the following error:
ORA-12170: TNS:Connect timeout occurred
Has anyone tried anything similar or seen a similar problem?
Oracle 10 XE running on a CentOS 5.5 VM in VMWare Fusion
I know the DB is up and running since I can connect to it using DBVisualizer
and my command line tool runs fine.
I have tried turning off the firewall on both the MacOSX and CentOS but to no
avail.
I have also tried su to the admin user and then running XCode from the terminal
as root with sudo open <path to XCode executable>
Via printfs I know the initialize call is working.
Here is the code:
- (void) applicationDidFinishLaunching: (NSNotification *) aNotification
{
printf ("--> A\n");
OCI_Connection* cn;
OCI_Statement* st;
OCI_Resultset* rs;
if (!OCI_Initialize (NULL, NULL, OCI_ENV_CONTEXT))
{
OCI_Error *error = OCI_GetLastError();
printf ("--> Initialize failed: code = %d, msg = %s\n",
OCI_ErrorGetOCICode (error), OCI_ErrorGetString (error));
OCI_Cleanup();
return;
}
printf ("--> B\n");
cn = OCI_ConnectionCreate ("xe", "ddi", "kitty", OCI_SESSION_DEFAULT);
if (cn == NULL)
{
OCI_Error *error = OCI_GetLastError();
printf ("--> Create connection failed: code = %d, msg = %s\n",
OCI_ErrorGetOCICode (error), OCI_ErrorGetString (error));
OCI_Cleanup();
return;
}
printf (OCI_GetVersionServer(cn));
st = OCI_StatementCreate (cn);
if (st == NULL)
{
OCI_Error *error = OCI_GetLastError();
printf ("--> Create statement failed: code = %d, msg = %s\n",
OCI_ErrorGetOCICode (error), OCI_ErrorGetString (error));
OCI_Cleanup();
return;
}
OCI_ExecuteStmt (st, "select count(*) from location");
rs = OCI_GetResultset (st);
while (OCI_FetchNext (rs))
{
printf ("Locations = %d\n", OCI_GetInt (rs, 1));
}
OCI_Cleanup();
}
So the create connection step is failing. I can see the main thread waiting for
the connection as I get the spinning color wheel cursor. It times out after
about 30-45 seconds. Running the same code in a simple .c file runs instantly.
Any help appreciated.
Thanks.
