Slow application performance

While it's true that the iSeries database is shipped pre-tuned for traditional RPG applications, there is an increasing number of situations where additional time is required to fine-tune the database, Including:

  • A query intensive SQL environment in which it is difficult for the iSeries administrator to anticipate which indexes should be pre-built and which indexes should be built temporarily by the system
  • An environment which relies on a frequently updated legacy application with a number of different developers writing SQL code that would benefit from a fast and efficient way of testing for performance BEFORE deployment
  • A system of OLTP applications and reports which increasingly relies on SQL rather than more traditional RPG programming and administration skills. SQL-based applications tend to be multi-platform, very complex, and posses difficult-to-understand query optimization technology
