It has been a reigning question, triggering endless discussions in various professional forums, hence the need for this article today. We are going to delve into the various features, functionalities and capabilities of the Oracle database version 9i and compare it to IBM’s Universal Database version 8.1. Aspects to be considered in this article include performance, requirements, support of platforms, TPC testing and of course price comparison.
Now to begin!
-
Platform comparison
The Oracle 9i as well as DB2 v8.1 can support all the known platforms – HP-UX systems, Windows-based platforms, Linux Intel, AIX-based systems, Sum Solaris among many others. For better comparison data for platforms, ask the Remote DBA Expert – http://www.remotedba.com/.

Hardware requirements
Oracle 9i database
The following hardware is necessary on order to be able to run the Oracle 9i database on a Windows-based platform:
- Pentium 166 MHz processor or higher
- 128 MB RAM Memory, though 256 MB is most advisable. Initial size of virtual memory should be 200MB, growing to a maximum size of 400 MB.
- Hard disk – system drive should be 140 MB at least, and an additional 4.5 GB on the FAT Oracle Home Drive (OHD) and 2.8 GB on NTFS OHD.
On UNIX Systems (AIX-BASED Systems, Linux Intel, Sun Solaris, HP 9000 Series HP-UX and Compaq Tru64 UNIX), the following hardware requirements are necessary:
- 512 MB RAM memory minimum
- Either 400 MB or 2x RAM swap space, whichever one is larger
- 5 GB hard disk space
DB2 Universal Database v8.1
Windows-based platforms must fulfill the following hardware requirements:
- Pentium processor or Pentium-compatible CPU
- 256 MB RAM memory minimum, though more may be required
- At least 350 MB on the hard disk for typical installation, 100 MB for the compact or custom installation options. Additional space may be necessary on FAT drives that have large cluster sizes.
UNIX systems conversely must fulfill the following:
- Processor: AIX – eServer pSeries or IBM RISC/6000; HP-UX – 700 or 800 system on HP 9000 series; Linux – Intel 64-bit, Intel 32-bit, Multiprise 3000, S/390 9672 generation or more recent, eServer z-Series.
- 256 MB RAM memory minimum, though more may be necessary.
- At least 450-550 MB on the hard disk for typical installation, 350-400 MB for the compact installation and 350-700 MB for custom installation options.

Performance comparison
Making a performance comparison between the two databases is quite difficult, since the efficacy and performance of a database predicates more on the developers and administrators of a database than on the database provider. Both RDBMSs are applicable with the result of an efficient and stable system.
However, one can define the typical transactions used in various systems – inventory control, banking, airline reservation – after which the transactions can run using either RDBMS to examine operation on different software and hardware platforms.
-
TPC testing
The TPC (Transaction Processing Performance Council) is an independent organization, which defines typical transactions (those used in in inventory control banking and airline reservation systems) and then stipulates rules to which these transactions must adhere.
The mandate of the TPC therefore is to give benchmarks that apply to the measurement of database performance and transaction processing, expressed as a number of transactions any system and/or database can perform within a unit of time.
There are various specifications set by the organization in this regard: TPC-W, TPC-R, TPC-H and TPC-C as well as older versions line the TPC-D, TPC-B and TPC-A. Of these, the TPC-C test is the most popular and most widely applied and as at the time of writing this article, Oracle held the top spot for the TPC-C by performance result.
However, this score is more relevant to companies that operate larger databases, since the key points of the TPC-C test depends on attributes applicable to larger databases.
