1 INTRODUCTION

This README file is relevant only to the delivered Oracle Net Services release 2 (9.2) product. This README documents any differences between the Oracle Net Services and its documented functionality, as well as known problems and workarounds. Operating system releases, such as UNIX, Windows NT, and so on, often provide an Oracle operating system-specific README document.

For information about upgrading, downgrading, and migration, see Oracle9i Database Migration.

Oracle Net Services is the foundation of Oracle's family of networking products, providing the industry's most comprehensive, enterprise-wide data access solution for the heterogeneous distributed computing environments. It enables both client/server and server/server communications across any network. Oracle Net Services offers the following benefits:

2 INSTALLATION

A release 9.2 listener is required for an Oracle9i release 2 (9.2) database. Previous versions of the listener are not supported for use with an Oracle9i release 2 (9.2) database. However, it is possible to use a release 9.2 listener with previous releases of the database.

Oracle operating system-specific documentation for more information about client and server installations.

3 DIRECTORY NAMING

Directory naming support in this release enables configuration of a root Oracle Context in an Oracle Internet Directory (dn:cn=OracleContext). However, directory naming support in Oracle8i release 8.1.7 and 8.1.6 does not support an Oracle Context at the root of the directory. To ensure that directory naming works for both Oracle9i and Oracle8i clients, use an Oracle Context that is not located directly under the root of the directory.

[Reference Bugs 1784971 and 1777306]

4 ORACLE NAMES LDAP PROXY SERVERS

For complex migrations, the Oracle Names Control utility's DUMP_LDAP command enables migration from an Oracle Names domain structured directory to an LDAP-compliant directory server with a directory information tree (DIT) structure. The hierarchical structure for each of these systems is comparable, and it is possible for any domain tree to be replicated in the DIT. The DUMP_LDAP command also enables rearrangement of the tree structure during migration, from any domain structure to any possible other DIT structure.

Oracle Names LDAP Proxy servers, which are used after the data is migrated into a directory server, rely on topology checkpoint files. Checkpoint files are generated from the old Oracle Names administrative region as source topology data for the proxy server. This topology data defines the region structure for all Oracle Names servers or Oracle Names LDAP Proxy servers. Every region has a single topology definition; each server's topology checkpoint file should be an identical replica of this definition. By default, the topology checkpoint file has a file name of cktop.ora and resides in the $ORACLE_HOME/network/names on UNIX, and the ORACLE_HOME\network\names on Windows NT.

Most cases of migration from multiple administrative regions in Oracle Names to a DIT structure that is not the same requires modification of the region structure in the topology file. Region restructuring occurs if changes are made to domains which are definitive elements of the topology, or if the region boundaries are altered. Every possible case of domain restructuring may or may not require region restructuring. For instance, in a single-region network you can change the domain structure without requiring a topology change. The following constitute a topology change:

Oracle Net Services tools do not currently support topology modification. However, topology definitions can be modified manually by editing the topology checkpoint files, according to the rules described in http://metalink.oracle.com/cgi-bin/cr.cgi?283548. Using existing topology files as a template, you can set up an Oracle Names LDAP Proxy server to support any region structure allowed for a given DIT.

5 TRCROUTE UTILITY

The TRCROUTE utility for UNIX operating systems enables administrators to discover what Oracle Net Services route a connection takes from a client to a database server. If there is an address list containing SOURCE_ROUTE=on, as is the case with Oracle Connection Manager where there is more than one hop to the database server, this utility does not work.
