Leveraging DB2 Snapshot Administrative Views

27-May-09

This article will show the DB2 LUW version 9 administrator how to use Unix shell scripts to build a home-grown database performance history system without resort to third-party tools. Shell scripts are used to automate performance capture and provide 24×7 monitoring support. The author also provides 40 views representing calculated common metrics of the resulting performance history data.

Unix Housekeeping for the DB2 DBA

19-Dec-08

Active Unix DB2 databases generate and store substantial support information outside of the database itself, in flat text files and binary dumps. If as a Unix DBA you do your administration work largely via Unix shell session, you probably have files comprising SQL, data exports, scripts, generated reports and performance monitoring output which need maintenance. We must, in the course of our work, monitor, maintain and prune those files. File maintenance, in my experience, is one of the most commonly neglected parts of a DBA’s work, often because it is not explicitly delegated; we all assume someone else is going to do the work. DB2-related Unix directories comprise part of the collective memory of the DB2 and are valuable as history, documentation, training, team communication and for the reuse of components.
