Version numbering

Since version 7, Oracle's RDBMS release numbering has used the following codes:

Oracle7: 7.0.16 — 7.3.4
Oracle8 Database: 8.0.3 — 8.0.6
Oracle8i Database Release 1: 8.1.5.0 — 8.1.5.1
Oracle8i Database Release 2: 8.1.6.0 — 8.1.6.3
Oracle8i Database Release 3: 8.1.7.0 — 8.1.7.4
Oracle9i Database Release 1: 9.0.1.0 — 9.0.1.5 (patchset as of December 2003)
Oracle9i Database Release 2: 9.2.0.1 — 9.2.0.8 (patchset as of April 2007)
Oracle Database 10g Release 1: 10.1.0.2 — 10.1.0.5 (patchset as of February 2006)
Oracle Database 10g Release 2: 10.2.0.1 — 10.2.0.4 (patchset as of April 2008)
Oracle Database 11g Release 1: 11.1.0.6 — 11.1.0.7 (patchset as of September 2008)

The version-numbering syntax within each release follows the pattern: major.maintenance.application-server.component-specific.platform-specific.

For example, "10.2.0.1 for 64-bit Solaris" means: 10th major version of Oracle, maintenance level 2, Oracle Application Server (OracleAS) 0, level 1 for Solaris 64-bit.
