The CPU requirements for an upgrade depend on many factors, including:
• The size of the database
• The volume of data in the primary product installation group
Note: You may have multiple Primary Products.
• The number and duration of long-running patch worker processes associated with
products that have intensive upgrade operations
• Desired response time
Note: Refer to Oracle E-Business Suite Maintenance Guide for
recommendations on the number of workers (adworker) to use during
AutoPatch, or during the upgrade (unified driver).
A test upgrade of the largest Oracle production system (oraprod) used the following
• Database tier machine - 24 CPUs (900 MHz SUNW, UltraSPARC-III+)
• Application tier machine - 4 CPUs (3.05 GHz Intel Xeon)
A test upgrade of the Vision database and application tier machine used 4 CPUs (3.05
GHz Intel Xeon).
Note: See Applications Release 12 Upgrade Sizing and Best Practices for the
statistics on these production system upgrades.
To calculate the memory requirements for an upgrade, consider the following:
• Number of concurrent users
• Infrastructure requirements for multi-tiered architecture
A test upgrade of the largest Oracle production system (oraprod) used the following:
• Database tier machine - 48 GB of memory
• Application tier machine - 12 GB of memory
A test upgrade of the Vision database and application tier machine used 6 GB of
Note: For statistics on these production system upgrades, refer to
Applications Release 12 Upgrade Sizing and Best Practices.
Note: For minimum memory and swap space requirements, refer to the
relevant Oracle E-Business Suite platform-specific Installation and Upgrades
Notes (IUN) and the Rapid Install Guide for 11gR2 sizing available on My
Oracle Support Knowledge, and the Oracle E-Business Suite
Documentation Resources, Release 12.2 document (Doc ID: 1498411.1).
Disk Space Requirements
The approximate file system disk space requirements for a standard installation are:
Node: Space Required:
Applications node file system (includes OracleAS 10.1.2 Oracle Home, Oracle FMW
Oracle Home, COMMON_TOP, APPL_TOP, and INST_TOP)
64 GB (for the dual file system required by online patching - see note below)
Database node file system (Fresh install) 90 GB
Database node file system (Vision Demo database) 200 GB
The database node disk space requirements for both the production database and the
Vision Demo database include database files (.dbf) and the 11gR2 database Oracle
