WE BSPHERE PORTAL V6.1 TUNING GUIDE
O R A C L E D A T A B A S E S E R V E R T U N I N G
WebSphere Portal V6.1 uses database servers for core functionality. In this measurement
environment, we used Oracle database server for the Portal application. The LDAP server,
IBM Tivoli Directory Server included a DB2 database as a repository.
PL AN N I NG FO R O RAC L E EN T E RPRI SE E DI TI O N D AT AB AS E
For our Solaris platform measurements we also used Oracle 10g R2 as our database
server. WebSphere Portal V6.1 uses the concept of Database domains to designate either
groups of tables belonging to one domain, or even entirely separate databases to store the
data specific to each domain.
On Oracle, we built a single database and create Oracle users to own the tables and data
needed to support each domain. The domains are listed in PortalDatabaseDomain, above.
For the Base Portal measurements, the Release domain is the primary database being
exercised.
A well designed database can save a lot of trouble later down the road, and improve
database performance. We recommend that you refer to the Oracle Administrator’s
Guide to help you make informed database design decisions. Here are the key choices
we have implemented in our Oracle database.
• To avoid I/O contention and allow for better throughput, you should ensure your
database server have adequate number of disks. Our database is on seven stripped
disks.
• For better management and performance of storage structures, Oracle-Managed
Files are used for database, as well as redo logs, and control files.
• Database block size: 8k
• The following tablespace sizing was required to support roughly a medium sized
Portal, with 100,000 authenticated users, approximately 180 installed portlets and
220 pages, which the load generally consisting of database read operations. We
recommend monitoring your tablespace sizing and growth on a regular basis. We
used DBCA to create database with the following Tablespace size:
o SYSAUX: 800MB
o SYSTEM: 800MB
o TEMP: 800MB
o UNDOTBS: 1024MB
o USERS: 2048MB
• Redo log groups: 500MB each.
