The cost-based optimizer of IBM DB2 for z/OS has continually evolved since its initial inception. Support has included new optimization algorithms, join methods, complex relational data structures, such as star schemas. DB2 for z/OS V8 has provided ...
Reduce your load using a Db2 optimization tool with agentless architecture SolarWinds Database Performance Analyzer doesn’t need to install any agent or software on the server you’re monitoring, which places less than a 1% load on each monitored database instance. DPA server software is built ...
