Hi guru,

Module: JDBC Thin Client
SELECT DISTINCT ................................

      2,965       3,114          9        346.0    4.8    0.3 46yd4cxsngmqy
Module: JDBC Thin Client
^LSQL ordered by Physical Reads (UnOptimized)DB/Inst: DININV/dininv1  Snaps: 15
-> UnOptimized Read Reqs = Physical Read Reqts - Optimized Read Reqs
-> %Opt   - Optimized Reads as percentage of SQL Read Requests
-> %Total - UnOptimized Read Reqs as a percentage of Total UnOptimized Read Reqs
-> Total Physical Read Requests:       6,628,255
-> Captured SQL account for   36.2% of Total
-> Total UnOptimized Read Requests:         911,592
-> Captured SQL account for   13.6% of Total
-> Total Optimized Read Requests:       5,716,663
-> Captured SQL account for   39.8% of Total

UnOptimized   Physical              UnOptimized
