Now that I think about it, it might very well be so :)
DBA_ views vs. base tables would be a different story (uet$ & fet$ case with
LMT for example...)

Hi Prem,

I had earlier calculated the library cache and sql area size from X$ksmsp.
Please check the size of these component in x$ksmss.

Hi Manoj,
this is the statistics i got from one of my instance.
sql area 225 MB
library cache 112 MB
I was also confused as u were [ i didn't notice this so far ].
but reading the replies of Tanel & Steve once again:
But what Steve meant (please correct me if I'm wrong), is that operations
on
sql areas are managed by library cache structures (library cache latch,
KGL
manager, lib cache hash table, etc), so sql area is dependent on library
cache, despite the fact they both have memory allocated directly from
shared pool.
from this (and as per the docs) i understand that sql area is a subset of
library cache.
perhaps,what "subset" means is:
in terms of the control library cache has over sql area and not in terms
of memory allocated.
is my understanding correct, Tanel ?
My best guess at the moment is that when new recreatable chunks are first
unpinned,
they go onto the transient list, and then when they have been reused, they
go back
onto the recurrent list.
..and reading this post by Steve,i feel there is something more(a lot)
that
we need to
know/understand to discuss about this.
Can Steve/Tanel/List explain me what is transient chunk & recurrent chunk
?
Regards,
Jp.

RE: "SQL AREA" and "LIBARARY CACHE" size?
Hi Tanel, There was a note in the bug database back in 7.1 days that suggested that it was hard coded based on the chunk type, and so that's what I wrote in my book. However, I fear that that might have been wrong. At least it is in recent versions. It is not hard to set up a test in which you can see chunks moving from the transient to recurrent list. My best guess at the moment is that when new recreatable chunks are first unpinned, they go onto the transient list, and then when they have been reused, they go back onto the recurrent list. @ Regards, @ Steve Adams @ http://www.ixora.com.au/ - For DBAs @ http://www.christianity.net.au/ - For all -Original Message- Tanel Poder Sent: Thursday, 25 September 2003 9:45 PM To: Multiple recipients of list ORACLE-L As I understand SQL area is a subset of library cache which is a subset of shared pool. Taking advantage the opportunity that Steve is here, I'd like to ask how does Oracle distinguish between recurrent and transient chunks? Is this hardcoded, that certain types of chunks go to transient end of LRU list and others go to rcr end or is this based on some kind of touch count as well, like in buffer cache LRU list?

Re: "SQL AREA" and "LIBARARY CACHE" size?
Well, if you look it from memory allocation point of view, then during startup, a heap in size of shared_pool_size is allocated for shared pool and all memory allocations for library cache, sql area, pl/sql mpcode, KGL library cache manager structures, etc, are made from the same shared pool heap (providing that only one heap is configured). So different memory chunks are mixed up in the shared_pool, there is no such mechanism, which divides shared pool to "sql part" and "library cache object" part or similar. Only exceptions I can think of are shared pool reserved area and also I remember something about heap manager "hiding" half of shared pool for startup duration. v$sgastat just shows you the sums of chunk sizes for different types of objects. But what Steve meant (please correct me if I'm wrong), is that operations on sql areas are managed by library cache structures (library cache latch, KGL manager, lib cache hash table, etc), so sql area is dependent on library cache, despite the fact they both have memory allocated directly from shared pool.

RE: "SQL AREA" and "LIBARARY CACHE" size?
>From 9.2 doc:
Shared Pool
The shared pool portion of the SGA contains three major areas: library
cache, dictionary cache, buffers for parallel execution messages, and
control structures.
The total size of the shared pool is determined by the initialization
parameter SHARED_POOL_SIZE. The default value of this parameter is 8MB on
32-bit platforms and 64MB on 64-bit platforms. Increasing the value of this
parameter increases the amount of memory reserved for the shared pool.
Library Cache
The library cache includes the shared SQL areas, private SQL areas (in the
case of a multiple transaction server), PL/SQL procedures and packages, and
control structures such as locks and library cache handles.
Shared SQL areas are accessible to all users, so the library cache is
contained in the shared pool within the SGA.

Waleed

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?

RE: "SQL AREA" and "LIBARARY CACHE" size?
Yes. Just increase the SHARED_POOL_SIZE parameter and you've increased both library cache and SQL area. Not just that, you've also increased the row cache as well. -- Mladen Gogala Oracle DBA > -Original Message- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of ManojKr Jha > Sent: Thursday, September 25, 2003 3:10 AM > To: Multiple recipients of list ORACLE-L > Subject: "SQL AREA" and "LIBARARY CACHE" size? > > > > > > Hi, > > Any body have any idea about how to control the size of > "library cache" and "sql area" in shared_pool? > > With Regards, > Manoj Kumar Jha > -- > -- > > > A transcendentalist engaged in auspicious activities does not > meet with destruction either in this world or in the > spiritual world; one who does good, is never overcome by evil. > -- > -- > > DISCLAIMER: The information contained in this message is > intended only and solely for the addressed individual or > entity indicated in this message and for the exclusive use of > the said addressed individual or entity indicated in this > message (or responsible for delivery of the message to such > person) and may contain legally privileged and confidential > information belonging to Tata Consultancy Services.

Prem Khanna, Yes I know that Steve is master of unix/oracle internals, that why I want to clarify my doubt. I had doubt that why I asked you fine people. Yes as far doc. and references are concerned, all clearly say that sql area is subset of library cache. but my doubt is due to size of these two components in shared pool. it is Library cache which may be subset of SQL area which intern subset of shared pool. If it is not then subset will be larger than set. Which is not possible. Please confirm with your database that what are size of LIBRARY CACHE and SQL AREA? In my system size of library cache is approx 48 mb and sql area 417 mb.

Re: "SQL AREA" and "LIBARARY CACHE" size?
As I understand SQL area is a subset of library cache which is a subset of shared pool. Taking advantage the opportunity that Steve is here, I'd like to ask how does Oracle distinguish between recurrent and transient chunks? Is this hardcoded, that certain types of chunks go to transient end of LRU list and others go to rcr end or is this based on some kind of touch count as well, like in buffer cache LRU list?
