This preface describes the new networking features of Oracle Database 11g and provides pointers to additional information.
The new features for Oracle Net Services in Oracle Database 11g include:
Enhanced Network Administration Security
Non-Anonymous LDAP Access for Net Naming
Database administrators can now restrict access to a service by associating an access control list (ACL) with it. This feature can be used with installations that require an extremely high level of security.
New Oracle Net fastpath for the common usage scenarios significantly improves Oracle Net performance and is enabled by default in Oracle Database 11g. Users do not need to perform any configuration for this feature.
Efficient network support for bulk data transfers (for example, LOBs). This feature relaxes the notion of session data unit (SDU) and optimizes large data transfers over an Oracle Net connection by using new paradigms. See "Session Data Unit (SDU) Size".
This feature adds Oracle Net support for efficient event-dispatch mechanisms on platforms that support them. This is internally enabled for PHP usage scenarios and users do not need to perform any configuration for enabling this feature.
Fast Reconnects for High Availability (HA)
This feature adds a mechanism for efficient dead node detection for connect time failover. Configurable timeouts have been implemented at various levels.
Support for Database Resident Connection Pooling
This feature enables you to share connections or sessions between multiple middle-tier processes
Enhancements to the Easy Connect Naming Method
For TCP/IP environments, you can simplify client configuration by using the easy connect naming method. The easy connect naming method simplifies network management by allowing clients to connect to Oracle Database services without first configuring net service names. Instead, clients make connections with the host name and optional port and service name of the database. See "Using the Easy Connect Naming Method".
