I wanted to find out how ‘big’ the new Oracle EBS 12i release really is. So, I downloaded the software from Edelivery and created a stage area.

From the stage area I started the rapidwiz to check the required disk space. Here is the required disk space for Oracle EBS 12i :

Database ORACLE_HOME = /ebs/db/tech_st/10.2.0
required = 4234.0

Database System File Directory = /ebs/db/apps_st/data
required = 19487.0

Database Log File Directory = /ebs/db/apps_st/data
required = 3165.0

Database Transaction File Directory = /ebs/db/apps_st/data
required = 66244.0

Database Archive File Directory = /ebs/db/apps_st/data
required = 45061.0

APPL_TOP = /ebs/apps/apps_st/appl
required = 5078.0

APPL_TOP mount 2 = /ebs/apps/apps_st/appl
required = 2639.0

APPL_TOP mount 3 = /ebs/apps/apps_st/appl
required = 4167.0

APPL_TOP mount 4 = /ebs/apps/apps_st/appl
required = 2882.0

COMMON_TOP = /ebs/apps/apps_st/comn
required = 2743.0

Apps ORACLE_HOME = /ebs/apps/tech_st/10.1.3
required = 1553.0

Tools ORACLE_HOME = /ebs/apps/tech_st/10.1.2
required = 1138.0

So, you see the database is much bigger then release 11.5.10.2 (10g vs 9i). Also the new APPL_TOP is a little bigger then the old one.

To check for yourself, here is the required disk space for Oracle EBS 11.5.10.2

Database ORACLE_HOME
required = 3091.0

Database System File Directory
required = 12023.0

Database Log File Directory
required = 160.0

Database Transaction File Directory
required = 28870.0

Database Archive File Directory
required = 21206.0

APPL_TOP
required = 5707.0

APPL_TOP mount 2
required = 3212.0

APPL_TOP mount 3
required = 5852.0

APPL_TOP mount 4
required = 2524.0

COMMON_TOP
required = 2963.0

Apps ORACLE_HOME (iAS)
required = 2600.0

Tools ORACLE_HOME (8.0.6)
required = 3027.0
