Home -> Community -> Mailing Lists -> Oracle-L -> RE: "SQL AREA" and "LIBARARY CACHE" size?
Hi Manoj,
Although the stats are confused, the "SQL area" is in fact a subset of the library cache. Cursors are cached in the library cache as namespace 0.
You can exercise limited control over the memory usage by marking objects for keeping with DBMS_SHARED_POOL.KEEP. Otherwise, the retention of chunks and thus the relative size of these and other shared pool areas depends entirely how recently objects have been used, because they all share the same LRU mechanisms (although there is an additional subordinate LRU mechanism for the dictionary cache).

How the ORACLE distribute and mange the size of variouse component in
shared_pool....?
There should be some criteria on which it disribute its toatl available
memory to these component.
Steve Adams/Jonathan, do you have any about these?
Also are there any way to control the number and type of chunks in
different buckets.
If these can be manage I hope that lots of seriouse problem related to
shared pool fragmentation and other issues can be easilly avoided?
With Regards,
Manoj Kumar Jha

You cannot control the sizes of sql area and library cache individually
