hello all,

When querying this view in regards to the v$sga_shared_pool advisory , i get results but not sure how to interpret the ESTD_LC_TIME_SAVED column ?
It's a time in seconds benchmark to what? and is it in thousands of seconds ?

EST_SIZE FACTOR ESTD_LC_SIZE ESTD_LC_TIME_SAVED HITS

160 0.5 162 215103 43148850
192 0.6 193 215285 43173155
224 0.7 224 215391 43188435
256 0.8 255 215470 43200068

Thanks

Thank you for your reply. I am not clear exactly if the seconds are in thousands or is there a decimal somewhere ?

EST_SIZE FACTOR ESTD_LC_SIZE ESTD_LC_TIME_SAVED HITS

160 0.5 162 215103 43148850
192 0.6 193 215285 43173155
224 0.7 224 215391 43188435
256 0.8 255 215470 43200068

I just wanted to know if it's ~59 hrs.

Documentation - it's not just there to look good on the bookshelf.

The time is in seconds, and the column represents the esimated total saving in parse time since the database started.
