====== Oracle Installation & Maintenance ======

=====Silent Installation======
Unlike some databases (working ones) which have a command line installation (DB2) or are installed as a service (PostegreSQL, MariaDB, MySQL and others) Oracle is little noisy queen when it comes to installation GUI installation. So in order to save a lot of dead neurons, here is a easy way how you can install silent Software ONLY:

<sxh bash>
[oracle@tbp-mts-odb01 database]$ ./runInstaller -ignoreSysPrereqs -ignorePrereq -waitforcompletion -showProgress -silent \
>     -responseFile /home/oracle/database/response/orainstall_se_response.rsp \
>     oracle.install.option=INSTALL_DB_SWONLY \
>     ORACLE_HOSTNAME=${ORACLE_HOSTNAME} \
>     UNIX_GROUP_NAME=oinstall \
>     INVENTORY_LOCATION=/app/oracle/oraInventory \
>     SELECTED_LANGUAGES=en,en_GB \
>     ORACLE_HOME=/app/oracle/product/11.2.0/dbhome_1 \
>     ORACLE_BASE=/app/oracle \
>     oracle.install.db.InstallEdition=SE \
>     oracle.install.db.DBA_GROUP=oinstall \
>     oracle.install.db.OPER_GROUP=oinstall \
>     oracle.install.db.BACKUPDBA_GROUP=oinstall \
>     oracle.install.db.DGDBA_GROUP=oinstall \
>     oracle.install.db.KMDBA_GROUP=oinstall \
>     SECURITY_UPDATES_VIA_MYORACLESUPPORT=false \
>     DECLINE_SECURITY_UPDATES=true
