Presentation owner: Rick Sobiesiak Triton Consulting conducted an objective assessment of the complexity of several routine DBA activities, comparing Oracle Database 11gR2 and DB2 9.7. This study examines the following common DBA activities, and assesses the complexity of each within an Oracle Database and DB2 for LUW environment: 1 - Installation 2 - Enabling table compression 3 - Enabling index compression 4 - Backup and recovery 5 - Automatic memory tuning 6 - Data access control Each of these activities has been broken down into a number of more detailed steps, which are subjected to complexity analysis using the methodology described in the video. This presentation presents the high-level results and conclusions from the complexity analysis. For further details, including a detailed breakdown of the individual task complexity scores for each activity, please refer to the full Triton Consulting report entitled “Comparing DBA Productivity: An Oracle/DB2 Task Complexity Analysis” at https://www14.software.ibm.com/webapp/iwm/web/signup.do?lang=en_US&source=sw-infomgt&S_PKG=analyst-db2_oracle_triton

2. DBA Productivity & TCO
Productivity and ease-of-use are critical factors in the overall
TCO for a given IT system. The degree of complexity associated
is therefore a key differentiator.

4. Summary & Conclusions
Complexity Analysis Summary
Installation
Data Compression
Note: Lower bar
Index Compression (less complexity)
is better
Backup and Recovery
Automatic Memory Management
Authorisation
0 100 200 300 400 500 600 700 800
DB2 9.7 Oracle 11gR2

5. Findings: Activity 1 – Installation
Note: Lower bar
(less complexity)
is better
The DB2 complexity metric for the Install task is nearly 43% lower than with
Oracle Database.
The Information Management Specialists

6. Findings: Activity 2 – Data Compression
Overall Complexity for Data Compression Activity
Note: Lower bar
(less complexity)
DB2 for LUW 9.7 119.50 is better
Oracle Database 11gR2 238.00
0 50 100 150 200 250
Complexity Metric
The DB2 complexity metric is nearly 50% lower than with Oracle
Database.
The Information Management Specialists

7. Findings: Activity 3 – Index Compression
Note: Lower bar
(less complexity)
is better
There are no additional tasks required for DB2 index compression, so the DB2
complexity metric is 100% lower than with Oracle Database.
The Information Management Specialists

8. Findings: Activity 4 – Backup & Recovery
Note: Lower bar
(less complexity)
is better
The DB2 complexity metric is nearly 83% lower than with Oracle
Database
The Information Management Specialists

9. Findings: Activity 5 – Automatic Memory Tuning
Note: Lower bar
(less complexity)
is better
The DB2 complexity metric is nearly 90% lower than with Oracle
Database
The Information Management Specialists

10. Findings: Activity 6 – Data Access Control
Note: Lower bar
(less complexity)
is better
The DB2 complexity metric is nearly 81% lower than with Oracle Database
• DB2: simple revoke commands at database level
• Oracle Database: requires implementation of a virtual private database

11. Summary & Conclusions
Task Complexity Metric DB2
Advantage
DB2 9.7 Oracle Database
11gR2
Installation 326.5 570.5 43%
Data Compression 119.50 238 50%
Index Compression 0 189.50 100%
Backup and Recovery 72.5 439 83%
Automatic Memory Management 62.5 617 90%
Data Access Control 138 730 81%
DB2 holds a significant advantage in every single category
