TIPS FOR RUNNING 11I/R12 ON LAPTOP /COMPUTER
==================================
Do not make DEMO installation choose one module(like HR) during installation so your db wont be soo heavy.
Do not apply NLS patch
A minimum of 4GB RAM is recommeded for an EBS install.
For 11i, it would be enough (~3-4 GB RAM) but when you plan to upgrade to R12 you will find it slow and your patch workers may hang.
Processor - dual core preferable as fast as possible.
Also The processor model is not a constraint - you can use intel core i3-370, i5 , i7 processor or core 2 duo
You may want to consider an external USB 2.0 drive.

Software Requirements:
Operating System --> Required Maintenance Tools
Solaris --> (SPARC) ar, ld, make, X Display Server
Linux --> ar, gcc, g++, ld, ksh, make, X Display Server
Windows --> Microsoft C ++, MKS Toolkit, GNU make
HP-Tru64 --> ar, cc, ld, make, X Display Server
HP-UX --> ar, cc, acc, make, X Display Server
IBM AIX --> ar, cc, ld, linkx1C, make, X Display Server
CPU Requirements
CPU requirements for running Oracle Applications depend on:
• Number of concurrent users and their usage profiles
• Number of concurrent manager processes and the types of jobs that they are running
• Load for activities other than Oracle Applications
• Size of the database
• Desired response time
Because there are different product combinations, different user profiles, and different configurations, there is no one sizing answer for all hardware platforms. Some hardware vendors have sizing worksheets that model the CPU and memory requirements of Oracle Applications on their hardware.
Memory Requirements (RDBMS and Forms server)
To calculate the memory requirements on the machine where the RDBMS is
installed, consider the following:
• Oracle database overhead
• Size of System Global Area (SGA)
• Number of concurrent users
• Any non-Oracle software that has to run on this machine
Use a guideline of 25 MB per concurrent user to estimate the Applications requirements for the node where you install the Forms server.
Disk Space Requirements
Rapid Install installs the file system and database files for all products, regardless of their licensed status. The approximate file system requirements in a single-node installation are:
Tier Space Required
Application tier file system (includes iAS ORACLE_HOME, 8.0.6 ORACLE_HOME, COMMON_TOP, and APPL_TOP)
26 GB
Database tier file system (fresh install with a production database)
31 GB
Database tier file system (fresh install with a Vision Demo database)
65 GB
The total space required for a single node system, not including the stage area, is 57 GB for a fresh install with a production database, and 91 GB for a fresh install with a Vision Demo database.

********* RAM SHOULD BE MORE THAN 2 GB FOR R12 **********************
As much as you can afford! Mid to high range.
If you want both you'll need a heap of disk - you could go external or very large internal. As an example for R12.1 Software and Vision DB is minimum 260GB, and that doesn't include O/S, etc. or R11i.
Memory - go for 3Gb+ if you want R12 to run, I'd go with 4Gb
Processor - dual core preferable as fast as possible.
2.1Ghz should be fine.
Example hardware:
Toshiba Satellite A300 / Y01
Intel Pro Core2 Duo processor T9400 2.53GHz
Hard disk drive 640GB (320GB + 320GB) (5400rpm) SATA
Memory 4GB DDR2 (2GB + 2GB) (800MHz)
The 3GHz minimum is most likely a recommendation for production servers. The installer is not going to tell you "CPU too slow...cannot continue". Memory and disk space are far more likely to be the limiting factors in a single-user system -- I assume that you won't be supporting a development team of 20 just from your laptop.
I actually run my test EBS instances in VMware, but here are the specs on my laptop:
CPU: 2.4 GHz Intel Core 2 Duo
Memory: 4GB 667 MHz DDR2 SDRAM
Internal HD: 150GB SATA 5400 RPM (not large enough for running Oracle Apps, so I also have...)
External HD: 500GB, 5400 RPM
