Pre-requisite for database software installation


Oracle database is the set of related data collections, we can call it as Relational database management system (RDBMS) or just Oracle. While comparing to any other database solution oracle is one of the powerful DBMS with many features such as tune-able, reliable and scalable. Oracle produce separate hardware for oracle softwareís, but same can be used in any other vendor products too.
Setting Up Prerequisites for Oracle

Setting Up Prerequisites for Oracle

In 1977 Larry Ellison and his friends founded a software development system as oracle. In 1978 Oracle released its 1st version and later in 1979 they released the version 2 which was commercially used. The current version of oracle is 12c (C stands for Cloud) with cloud features. Oracle provides several supports regarding the products which includes troubleshooting supports patches and updates, which makes it rock solid, because it is very easy to organize different applications data. While comparing to any other database management Oracle is costly and mostly used for commercial purpose, almost everywhere, e.g: Banking, Universities for results, commerce related departments etc.

Oracle supports almost every operating systems such as Linux, HP-UX, AIX, Oracle Solaris, IBM zLinux64, and Windows. Oracle packages are available for both 32bit and 64bit platforms.

For large-scale installation we need to use multicore processors with High availability.
Recommended minimum RAM needed for Oracle is 2GB or more.
Swap must be enabled double the size of RAM.
Disk space must be more than 8GB, its depends on edition which are we going to choose for installing.
/tmp directory must have free space more than 1GB for error free installation.
Supported Linux operating systems are RHEL, Centos, Oracle.
Both x86_64 and i686 packages are required for installation.
Screen resolution must be more than 1024◊768 resolution.

If your systems meets all the above requirements, then we are ready to move forward to start oracle installation. Please remember, here I am using CentOS 6.5 operating system with 32GB size of Virtual HDD and 4GB Memory for installation, but same steps can also be followed in RHEL, Oracle Linux too.
