This appendix describes coexistence and upgrade issues for Oracle Net Services. This appendix covers the following topics:
Typical users of directory naming (LDAP) require anonymous access to the Oracle Internet Directory for name lookup. If your Oracle Internet Directory software is upgraded to release 11g or later, then the default setting for Oracle Internet Directory has changed. The default now is to disallow anonymous access to the directory. The directory administrator will need to configure the directory to enable anonymous binds after upgrading the directory to release 11g. In addition, the way anonymous binds are configured in Oracle Internet Directory changed between Oracle Database 10g and Oracle Database 11g.
See Also:Oracle Internet Directory Administrator's Guide for additional information about anonymous binds
When migrating Oracle Database 11g Release 184.108.40.206 to Oracle Database 12c Release 1 (12.1) in an Oracle Real Application Clusters environment, non-default listeners are not migrated by Oracle Net Services Configuration Assistant. To migrate the non-default listeners, use the following procedure:
Use Oracle Database 11g Release 220.127.116.11 Oracle Net Services Configuration Assistant to remove the non-default listeners.
Use Oracle Database 12c Release 1 (12.1) Oracle Net Services Configuration Assistant to create the non-default listeners.
