Re: SQL Developer / Oracle Directory Server

I don't have an answer, but I am surprised that it works elsewhere. I'd expect em and other tools to fail as well.

Dear fellows,

I use Oracle Directory Server (ODS) 11.1.1.7.0 for database name resolution which works perfect except for SQL Server Developer. I'm currently on the version 4.1.5, but the problem reproduces on other versions as well.

The sole purpose of the ODS in question is names resolution. It is worth noting that the Oracle context is defined under the root DSE (DEFAULT_ADMIN_CONTEXT = ""). I'm getting following error when SQL Developer tries to load Oracle Contexts: "LDAP:error code 32 - No Such Object"

By looking into the ODS logs, I deduced the ldapsearch done by SQL Developer:

$ORACLE_HOME/bin/ldapsearch -h hostname -p port -b "" -s sub "objectClass=*" cn dn

The problem can also be reproduced by running the ldap search above. The reason for the error is that, unlike other types of LDAP, ODS doesn't allow the subtree searches on root DSE. What SQL Developer is trying to do is to discover all of the oracle contexts under the base entry, which in my case happens to be the root DSE.

I’ve investigated following options so far, though without success:

• enabling the subtree search on root DSE in ODS
• disabling the subtree search for oracle contexts in SQL Developer. In my case, it would be sufficient to take just the oracle context under the configured DEFAULT_ADMIN_CONTEXT.

Have I overlooked something? Any other ideas how to solve this problem?

I would like to avoid the migration of OracleContext to another subtree.

Many thanks,
