Oracle provides MD5/SHA checksums on the download page. Example commands:
md5sum p13390677_112040_Linux-x86-64_1of7.zip
sha256sum p13390677_112040_Linux-x86-64_1of7.zip
Compare against Oracle’s published values.
Open a terminal on your Linux machine and run: download oracle 11.2 0.4 for linux x86-64
wget -c --user-agent="Mozilla/5.0" \ --header="Cookie: oraclelicense=accept-securebackup-cookie" \ https://download.oracle.com/otn/linux/oracle11g/R2/linux.x64_11gR2_database_1of2.zip
wget -c --user-agent="Mozilla/5.0"
--header="Cookie: oraclelicense=accept-securebackup-cookie"
https://download.oracle.com/otn/linux/oracle11g/R2/linux.x64_11gR2_database_2of2.zip
Note: Oracle frequently updates cookie tokens. If the above fails, log in via browser, start the download, then copy the actual
wgetcommand from your browser’s developer tools (Network tab).
Despite the availability of 19c and 21c, 11.2.0.4 persists because: Oracle provides MD5/SHA checksums on the download page
If you are starting a new project, do not choose 11g. Select 19c (Long Term Release). But for maintenance and legacy support, 11.2.0.4 is the gold standard.
You check the boxes for the files.
(The other files are for Grid Infrastructure and clients, but for a standard database installation, files 1 and 2 are the treasure you seek.)
You click Download. The progress bar appears. It is slow. This is an old king of databases, heavy with history. You wait. Compare against Oracle’s published values
