A lot of enhancements have been made to the product architecture. In addition, new features have been added, some to be controlled by the administrator, and some that can be configured by the end users.
The Oracle SES midtier has moved from OC4J to Oracle WebLogic Server. This entails changes to the steps involved in configuring Single Sign-On and SSL. See Chapter 11, "Security in Oracle Secure Enterprise Search" for more information on Single Sign-On and SSL configuration.
Oracle Text index structure is enhanced to provide faster query response time.
Changes to index structure improves the performance of Oracle Text significantly. This option is enabled by default in Oracle SES, and results in significant improvement in the response time of the query engine.
Oracle SES index fragmentation level remains low even with active crawler activities.
Note:If you are upgrading from a previous version of Oracle SES, then you must run a post-upgrade script for these changes to be reflected in your installation.
New Features for Administrators:
You can now use the Administrator API to manage multiple instances of Oracle SES from a central location. See Oracle Secure Enterprise Search Administration API Guide for more information.
See Also:Oracle Secure Enterprise Search Administration API Guide for information on how to implement partitioning.
Space management options have been implemented to enable administrators to set limits on disk space usage. See "Managing Disk Space Usage" for more information.
The new Oracle File Change Detector (FCD) significantly reduces the duration of incremental crawls of NTFS sources. See "Setting Up NTFS Sources for UNIX" for more information.
OAM based SSO authentication is now available. See "Configuring Secure Search with OAM Single Sign-On" for more information.
Crawler cache storage in Oracle Database provides a secure, compressed repository for sensitive information. Caching can be enabled and disabled at the source level, rather than at the system level. See "Overview of the Oracle Secure Enterprise Search Crawler" for more information.
