In Oracle Enterprise Linux 7 /tmp data is stored on tmpfs which consumes memory and is too small. To revert it back to storage just run following command and REBOOT machine to be effective.
systemctl mask tmp.mount

1. Uncheck checkbox “I wish to receive security updates via My Oracle Support” and then click “Next” button.
2. Ignore following message and click “Yes” button.
3. Select “Skip software updates” and click “Next” button.
4. Ignore following message. Just click “Yes” button
5. Select “Create and configure a database” then click “Next” button.
6. Select “Desktop Class” and click “Next” button.
7. On the screen you need to define global database name and pluggable database name. Rest of options you can keep default. Then click “Next” button.
8. Accept default settings then click “Next” button.
9. Summary screen just before installation. It’s the last moment to make changes in previous steps. If you are ready click “Install” button.
10. Installation begins …
11. Unfortunately I received error during binaries linking
in log you should see
/usr/bin/ld: note: '__tls_get_addr@@GLIBC_2.3' is defined in DSO /lib64/ld-linux-x86-64.so.2 so try adding it to the linker command line /lib64/ld-linux-x86-64.so.2: could not read symbols: Invalid operation INFO: collect2: error: ld returned 1 exit status
12. To solve this problem do following as user Oracle
remove directory /ora01/app/oracle/product/12.1.0/db_1/lib/stubs
rm -rf /ora01/app/oracle/product/12.1.0/db_1/lib/stubs
backup file $ORACLE_HOME/rdbms/lib/env_rdbms.mk
cd $ORACLE_HOME/rdbms/lib/ cp env_rdbms.mk env_rdbms.mk.bck
make changes in $ORACLE_HOME/rdbms/lib/env_rdbms.mk
modify line 176

to

Once it’s done click “Retry” button on screen from point 11 to continue with installation. Linking should finish properly and binaries installation should continue.
13. In the end you will be asked to run as root two scripts. Once they are completed click “OK” button – installation will proceed.
/ora01/app/oraInventory/orainstRoot.sh /ora01/app/oracle/product/12.1.0/db_1/root.sh
18. Once binaries are installed automatically DBCA (database configuration assistant) will start to create new database.
19. You should see summary screen for your database. You can click “Password Management” to unlock and change passwords for default account. Click “OK” button.
20. Installation is finished. Click “Close” button.
21. Post installation steps
Edit the “/etc/oratab” file to set restart flag for ORA12C to ‘Y’.
ORA12C:/u01/app/oracle/product/12.1.0/db_1:Y
