BMC DB2 Entwicklungsstrategie, Performance Advisor und mehr! Peter Plevka, BMC Software

Agenda BMC DB2 Entwicklungsstrategie Performance Advisor Update Copyright 5/17/2010 BMC Software, Inc 2

General Development Direction Reduce peak MIPS usage Reduce risk for change Staying current with technology Innovate to increase value for you Copyright 5/17/2010 BMC Software, Inc 3

High Speed Structure Change DB2 V8 TRANSFORM Copyright 5/17/2010 BMC Software, Inc 4

High Speed Structure Change - TRANSFORM Simple or Segmented Tablespace to UTS PBG (e.g. extending 64GB limit). Non-large Partitioned Tablespace to Large Partitioned Tablespace (i.e. 4 byte RID to 5 byte RID). Partitioned by Range Tablespace to UTS PBR (benefit of segmented). Partitioned by Range Tablespace to UTS PBG (dropping the partitioning Index requirement). Change tablespace SEGSIZE. Change tablespace DSSIZE. Convert Indexes to COMPRESSed. Change Index PIECESIZE. DB2 V9 and 10 T R A N S F O R M Your Benefit Increased availability and productivity for high volume structure changes Copyright 5/17/2010 BMC Software, Inc 5

Compare Output Index Unterschiede Matching Columns (MT CL) went from 1 to 0 (got worse) Index name is truncated but it shows that a different one was used. Also, went to sequential prefetch. Copyright 5/17/2010 BMC Software, Inc 29

Compare Index Unterschiede V8 vs. V9 On DIA1 (XD02), only one index was defined with no stats. DHN1 had 4 indexes with stats. Copyright 5/17/2010 BMC Software, Inc 30
