>> i check the values in sqlarea in v$librarycache
Please rephrase. you mena v$librarycache.sqlarea?
There is no such column.

>>The reloads is increased by one.
Becuase the object defintion was "flushed" away and reloaded.

Mahesh,

I checked the row with namespace as sqlarea. The reloads are increased by 1 upon reexecution. Why are they flushed away and reloaded as no other activity is performed??How can i avoid that??

Thanks
Reena

Usually it is because of insufficient shared pool.

Edit:
Nope.
I am talking about v$librarycache.reloads value
are you talking about v$librarycache.namespace value getting incremented?
