2 Oracle Retail Data Warehouse 
Implementation Capacity Planning 
There is significant complexity involved in the deployment of Oracle Retail applications, 
and capacity planning is site specific. Oracle Retail strongly suggests that before 
installation or implementation you engage your integrator (such as the Oracle Retail 
Consulting team) and hardware vendor to request a disk sizing and capacity planning 
effort. 
Sizing estimates are based on a number of factors, including the following: 
ƒ  Workload and peak concurrent users and batch transactions 
ƒ  Hardware configuration and parameters 
ƒ  Data sparcity 
ƒ  Application features utilized 
ƒ  Length of time history is retained 
Additional considerations during this process include your high availability needs as 
well as your backup and recovery methods.  
Check Database Server Hardware Requirements 
Hardware requirements for the data warehouse database server or target server include: 
General Hardware Requirements Minimum  Recommended 
Memory 8GB 
12GB+ 
Multi-processors 
4 – highest MHz 
8+ – highest MHz 
CD-ROM drive (either local or network) 
 
 
Disk Space 
300 GB 
Site specific (refer to 
your RDW sizing 
information) 
Swap Space 
Equal to physical 
RAM 
2.5 times the physical 
RAM 
Note:
  This reflects the amount of space needed to install the 
database software, RETL software, as well as the RDW 
software, and still maintain an acceptable amount of usage 
on the UNIX file system. This may reflect external storage as 
well as internal, such as 50GB of internal space and a 250+ 
GB external RAID storage array. 
Sizing Factors and other suggestions to factor into the selection of a data warehouse 
server include: 
ƒ  Concurrent front-end user base. More concurrent users will require more database 
processing power from the server. 
ƒ  DASD connectivity. Typically, it is better if the fiber channel connectivity to provide 
the maximum throughput to disk. 
ƒ  Backup/Recovery requirements. Extra disks may be required for backup and 
recovery procedures. 
ƒ  Server backplane speeds. Depending on the architecture of the server backplane (or 
comparable links), memory access and/or CPU utilization may be a factor in 
performance.
