Oracle 12c Pre install script... almost perfect !

When installing Oracle 12c, on a Oracle Linux server, you can perform most of the prerequisites settings by using a cool script:

yum install oracle-rdbms-server-12cR1-preinstall

Problem is that the script fails when started (really, was out of the box / freshly installed from Oracle repos):

oracle-rdbms-server-12cR1-preinstall-verify

/bin/sed: -e expression #1, char 116: unknown command: `3'

/bin/sed: -e expression #1, char 116: unknown command: `3'

Error above can be rectified with the following change ( use ' instead of  " on line 570 )

cp /usr/bin/oracle-rdbms-server-12cR1-preinstall-verify /usr/bin/oracle-rdbms-server-12cR1-preinstall-verify.bak

vi /usr/bin/oracle-rdbms-server-12cR1-preinstall-verify

diff /usr/bin/oracle-rdbms-server-12cR1-preinstall-verify /usr/bin/oracle-rdbms-server-12cR1-preinstall-verify.bak

<             ${SED} -i /'^#[[:space:]]*$COMMENT'/d ${LIMITSFILE}

---

>             ${SED} -i /"^#[[:space:]]*$COMMENT"/d ${LIMITSFILE}

570c570

<           ${SED} -i /'^#[[:space:]]*$COMMENT'/d ${LIMITSFILE}

---

>           ${SED} -i /"^#[[:space:]]*$COMMENT"/d ${LIMITSFILE}

Then you can use the script that saves you time for settings a lot of parameters needed for prerequisites.
