Oracle Database 11g Release 2 11.2 0.4 Download ((exclusive)) Now
Guide: Downloading Oracle Database 11g Release 2 (11.2.0.4) Important: Oracle Database 11gR2 (11.2.0.4) is an older release. Oracle may require an account and licensing for downloads; ensure you comply with Oracle’s licensing terms before downloading and installing. This guide shows how to locate and download Oracle Database 11gR2 (11.2.0.4) for common platforms, plus checksum verification and recommended pre-download checks. 1) Prepare before downloading
Decide OS/version you need (Linux x86-64, Windows x64, Solaris, etc.). 11.2.0.4 builds differ by platform. Check hardware and software requirements: CPU, RAM, disk space (typical minimal requirements: 2+ GB RAM for small test installs, 6–10+ GB disk; production needs much more). Oracle account: create an Oracle SSO account (email + password) if you don’t have one — required for Oracle Software Delivery Cloud (edelivery) or Oracle Technology Network (OTN) downloads. Network: allow access to Oracle download servers; corporate firewalls or proxies may block or require authentication. Licensing: confirm whether you need a paid license for production; 11g may be out of public support.
2) Where to find 11.2.0.4 downloads
Oracle historically hosts installers on:
Oracle Software Delivery Cloud (edelivery.oracle.com) — full media and patches. Oracle Technology Network (OTN) / Oracle Database Downloads pages — sometimes older releases archived. Oracle Support (My Oracle Support, MOS) for patch sets and PSU; MOS requires support entitlement.
If you need the patch set specifically named 11.2.0.4, Oracle packaged this as Patch Set 4 for 11.2; files are often labeled 11.2.0.4 or 11.2.0.4.x.
3) Typical download paths and file names (examples)
Windows 64-bit installer often provided as:
win64_11gR2_database_1of2.zip and win64_11gR2_database_2of2.zip
Linux x86-64 (Red Hat / OL / CentOS compatible):
linuxamd64_11gR2_database_1of2.zip and linuxamd64_11gR2_database_2of2.zip
For Oracle-supplied patchset or PSU on MOS: patch numbers and instructions are in MOS notes.
