Hi Nilesh There seems to be precious little Oracle specific information available on the web. I am aware of the following presentations: http://www.google.co.uk/url?sa=t&rct=j&q=oracle%20capacity%20planning%20&source=web&cd=6&cad=rja&ved=0CEgQFjAF&url=http%3A%2F%2Fwww.processdox.com%2FDocuments%2F6340592-Oracle-Database-Capacity-Planning.pdf&ei=l9ptUJmBOYGV0QX504HACQ&usg=AFQjCNHu_6LvUQFz8x9c5Ol75s7hkg4QYA http://www.docstoc.com/docs/97623840/Performance-and-Capacity-Trend----Independent-Oracle-Users-Group I suppose the sky is the limit with this stuff, but I've found a good way of pulling something basic together is via the DBA_HIST_SYSMETRIC_SUMMARY AWR view (need to be licensed for the diagnostics and tuning pack). Refer to slide 55 of this presentation for an example query (a big thank you to the guys at CERN for this!): http://www.google.co.uk/url?sa=t&rct=j&q=cern%20capacity%20planning%20query&source=web&cd=1&ved=0CCMQFjAA&url=http%3A%2F%2Findico.cern.ch%2FgetFile.py%2Faccess%3FcontribId%3D10%26sessionId%3D6%26resId%3D1%26materialId%3Dslides%26confId%3D20080&ei=itttULSbDOjQ0QWjz4GoCQ&usg=AFQjCNH6LDcCQq_wP54849EKvJlW_wdR6Q&cad=rja You can use Excel and ODBC to graph your chosen metrics. Hope that helps Austin -- //www.freelists.org/webpage/oracle-l
