Last updated on OCTOBER 12, 2011
Applies to:Oracle Net Services - Version: 10.1.0.5 to 188.8.131.52 - Release: 10.1 to 11.2
Information in this document applies to any platform.
An Oracle client performing a name lookup will search DNS for SRV records in the following order:
1) _ldap._tcp._oid.domain 2) _ldaps._tcp._oid.domain
3) _ldap._tcp.domain 4) _ldaps._tcp.domain
If an OID formatted SRV record is found the DIR_SERVER_TYPE is set to "OID". If a standard SRV record is found then the DIR_SERVER_TYPE will be set to "UNKNOWN". The client will retrieve both the _ldap and _ldaps records for the determined type.
For more information about OID server discovery and SRV record priority and weighting see note 250675.1 "Dynamic OID Server Discovery using DNS"
The following example shows how to create OID formatted SRV records using Server Manager Console on Windows Server 2008.
