B Upgrade Considerations for Oracle Net Services

This appendix describes coexistence and upgrade issues for Oracle Net Services. This appendix covers the following topics:

B.1 Anonymous Access to Oracle Internet Directory

Typical users of directory naming (LDAP) require anonymous access to the Oracle Internet Directory for name lookup. If you upgrade your Oracle Internet Directory software release 11g or later, then the default setting for Oracle Internet Directory changes to disallow anonymous access to the directory. The directory administrator must 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.

B.2 Migrating a Non-default Listener to Oracle Database 12c Release 2 (12.2)

When migrating Oracle Database 11g Release to Oracle Database 12c Release 2 (12.2) 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:

  1. Use Oracle Database 11g Release Oracle Net Services Configuration Assistant to remove the non-default listeners.

  2. Use Oracle Database 12c Release 2 (12.2) Oracle Net Services Configuration Assistant to create the non-default listeners.
