Help connecting to an LDAP node

Question

Hi there.
I am trying to connect to an LDAP node using the Open Directory framework in Cocoa. I am using the following code to initiate a session and run a search.
- (void)awakeFromNib
[self startSearch:@"rickyd"];
- (void)startSearch:(NSString *)searchString
nodeName = @"http://test.com"; //i've also tried using the IP with no success
NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:@"test.com", ODSessionProxyAddress, [NSNumber numberWithInt:389], ODSessionProxyPort, NULL];
NSError *sessionError = nil;
[session initWithOptions:options error:&sessionError];
NSLog (@"%@", options);
if (sessionError)
NSLog(@"%@", sessionError);
NSError *nodeError = nil;
searchNode = [ODNode nodeWithSession:session name:nodeName error:&nodeError];
if (nodeError)
NSLog (@"%@", nodeError);
NSError *queryError = nil;
query = [[ODQuery alloc] initWithNode:searchNode forRecordTypes:kODRecordTypePeople
attribute:kODAttributeTypeAllAttributes matchType:kODMatchInsensitiveContains
queryValues:searchString returnAttributes:kODAttributeTypeAllAttributes
maximumResults:0 error:&queryError];
if (queryError)
NSLog (@"%@", queryError);
My application hangs, and get the following error in the console:
{quote}
Error Domain=com.apple.OpenDirectory Code=2000 UserInfo=0x100193090 "Unable to open Directory node with name http://test.com."
{quote}
Has anyone else used this particular method before and have some suggestions as to what I'm doing wrong? I'd appreciate any help.
Thanks,
Ricky.

Hi Fergal,
Although I use Oracle 8i (8.1.7.4) Enterprise Edition (on SUN [sparc] Solaris 7), I am assuming it is similar to your personal edition.
In order to connect to the Oracle database (via JDBC, I assume), you need the following three things:
1. The Oracle connection listener must be running. To do that I use the "lsnrctl" Oracle utility -- so I suggest you look for "lsnrctl.exe" somewhere under your Oracle installation directory.
2. The oracle database server must be running. To do that I use the "svrmgrl" Oracle utility.
3. The database (connection) URL you use (in JDBC) needs to be correct. The format of the URL is (assuming you are using the 'thin' driver):
jdbc:oracle:thin:@<host>:1521:<sid>where <host> and <sid> can be obtained by executing the following query (which I execute via Oracle's SQL*Plus utility):
select
   HOST_NAME  host
  ,INSTANCE_NAME  sid
from
   V$INSTANCEHope this helps you.
Good Luck,
Avi.
