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

  • 1.Technology comparision should never looks like 'Biased'. Your comparision is saying that DB2 is good than oracle on these topics, but not saying that DB2 is not good than oracle on these topics?
    2.These type of comparision makes person confused and later frustruted who have either choosen X technology in compare of Y tech.
    3.Before providing such 'affirmative' conclusion, you should post the link where you have raised the question and couple of higher experts has confirmed your findings.

    • Comparing DBA Productivity: AnOracle/DB2 Task Complexity Study Triton Consulting Ltd October 2010 The Information Management Specialists
    • DBA Productivity & TCOProductivity and ease-of-use are critical factors in the overallTCO for a given IT system. The degree of complexity associatedis therefore a key differentiator. The Information Management Specialists
    • Common DBA Tasks Analysed• Installation• Enabling data compression• Enabling index compression• Backup and recovery• Automatic memory tuning• Authorisation The Information Management Specialists
    • Summary & Conclusions Complexity Analysis Summary Installation Data Compression Note: Lower bar Index Compression (less complexity) is better Backup and RecoveryAutomatic Memory Management Authorisation 0 100 200 300 400 500 600 700 800 DB2 9.7 Oracle 11gR2 The Information Management Specialists
    • Findings: Activity 1 – Installation Note: Lower bar (less complexity) is betterThe DB2 complexity metric for the Install task is nearly 43% lower than withOracle Database. The Information Management Specialists
    • 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
    • Findings: Activity 3 – Index Compression Note: Lower bar (less complexity) is betterThere are no additional tasks required for DB2 index compression, so the DB2complexity metric is 100% lower than with Oracle Database. The Information Management Specialists
    • 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
    • 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
    • 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 The Information Management Specialists
    • 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 The Information Management Specialists
