Nice job explaining how DB2 can help manage growing data volumes! We’ll be exploring this topic more in depth on an April 30 broadcast, Big Data at the Speed of Business: http://ibm.co/BigDataEvent

Comment on Connect with Your DB2 Performance by Norm

I came across a similar problem with Accpac a number of years ago on DB2 LUW. Each enduser was on average consuming 8 database connections. On a small 2GB machine, DB2 agents handling connections was consuming most of the memory! Each window on the desktop that needed data access opened another connection. Connection pooling made the situation tolerable.

In another engagement, the DB2 server was installed on Windows with Active Directory. The authentication server was located in Halifax and the database server in Ottawa. The latency was about 5 seconds. This is fine for Windows users logging on once a day, but intolerable for Accpac users. As they open each window within the application, a new database connection is created. This made the application very sluggish. Ended up moving the database inside Linux to avoid AD.

Comment on Effects of Compression on DB2 Performance by Andy Ben-Dyke

Compression is a good way to relieve pressure on a production database. If effective, it may also be worth considering introducing an archiving policy, whereby “old” data is moved from production to a secure highly-compressed archive. As over 50% of data may be well suited for archiving, the cost savings can be significant (not to mention the benefits from a regulation perspective). There are a number of products on the market which help implement an automated end-to-end archiving process: IBM Optim, HP DB Designer, Applimation Informia, Clearpace NParchive, Solix etc.
