sql area

I am seeing excessive reloads being reported from v$librarycache
everytime I execute I see reloads increasing. Help this is the live production systems and sone queries are just not returning.

Hi

You can pin large sql packages using dbms_shared_pool.keep

Does the sql area only pertain to large packages. I am seeing the reloads grow currently at a vast rate and no packages I being executed.

Any other suggestions?

Hi

well you should try increasing the SGA then..but i suggest you first start reading the oracle performance tuning manuals.
