  • Many new SQL analytical functions like lag, lead and rank
  • ALTER FREELISTS command (previously done by DROP/CREATE TABLE)
  • Checksums always ON for SYSTEM tablespace allowing many possible corruptions to be fixed before writing to disk (DB_BLOCK_CHECKING).
  • XML Parser for Java

  • New CASE statement in SQL similar to the Decode() function
  • New SQL*Plus command line options: sqlplus -MARKUP [HTML...] and -RESTRICT
  • User and Schemas separated

  • Numerous Performance Enhancements

[edit] Oracle 8i (8.1.5) - February 1999

  • Fast Start recovery - Checkpoint rate auto-adjusted to meet roll forward criteria
  • Reorganize indexes/index only tables which users accessing data - Online index rebuilds
  • Log Miner introduced - Allows on-line or archived redo logs to be viewed via SQL
  • OPS Cache Fusion introduced avoiding disk I/O during cross-node communication
  • Advanced Queueing improvements (security, performance, OO4O support
  • User Security Improvements - more centralisation, single enterprise user, users/roles across multiple databases.
  • Virtual Private Database (VPD)
  • Integrated JavaVM (called Aurora) in the database kernel allowing one to execute Java stored procedures
  • Integrated support for EJB (Enterprise JavaBeans)
  • JSQL: a specification for Java-based SQL database statements
  • Integrated Object Request Broker for standard CORBA communications between applications and the database
  • Oracle iFS (Internet File System)
  • Resource Management using priorities - resource classes
  • Hash partitioning and Composite partitioning
  • New partitioning features: merge partitions into one, updatable partition keys (allow movement of rows between partitions), can use LOBS in partitioned tables
  • Single table hash clusters
  • SQL*Loader direct load API
  • Copy optimizer statistics across databases to ensure same access paths across different environments.
  • Standby Database - Auto shipping and application of redo logs. Read Only queries on standby database allowed.
  • Enterprise Manager v2 delivered - completely rewritten in Java

  • Analyze tables in parallel.
  • Temporary tables supported (Tables that will be truncated at the end of a transaction or session).
  • Net8 support for SSL, HTTP, HOP protocols
  • Transportable tablespaces, copy tablespaces with datafiles between databases
  • Locally managed tablespaces - automatic sizing of extents, elimination of tablespace fragmentation, tablespace information managed in tablespace (i.e moved from data dictionary) improving tablespace reliability
  • Drop column on table (finally!!!!!)
  • DBMS_DEBUG PL/SQL package, DBMS_SQL replaced by new EXECUTE IMMEDIATE statement
  • Progress Monitor to track long running DML, DDL
