SGA resize
Can we resize SGA after setting SGA_MAX_SIZE to some number.
what parameters will be considered whule allocating this size.
I hope you are talking about dynamic SGA feature of 9i. Following link would help you in this regards.

Reduced SGA_TARGET, but SGA size not changing?
I reduced the sga_taget from 1536M to 512M:
alter system set sga_target = 500M scope = memory;
System altered.
select VERSION from v$instance;
VERSION
10.2.0.3.0
show parameter sga
NAME TYPE VALUE
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 1536M
sga_target big integer 512M
But the real memory still showing the original value
show sga
Total System Global Area 1610612736 bytes
Fixed Size 2030456 bytes
Variable Size 1509950600 bytes
Database Buffers 83886080 bytes
Redo Buffers 14745600 bytes
why is that while it's a dynamic parameter?
Thanks a lot for any help.

Edited by: user10484253 on May 13, 2011 8:41 AMI would suggest you to check v$sgastat to find out the exact SGA memory you are using currently instead of using "SHOW SGA" when when you set SGA_MAX_SIZE & SGA_TARGET initialization parameters.
Below is a sample output from one of my test dbs. As you can see below my SGA size is only 1GB.
SHOW SGA shows 2GB thats because I have set SGA_MAX_SIZE to 2gb ( which only means that I can grow my sga up till 2 gig , it may not be my current sga size).
you can try increasing or decreasing SGA_TARGET and check memory usage on OS level to see the difference.

Overheads of Automatic SGA.
Hello
What are peformance overheads of turning on Automatic SGA(SGA_TARGET > 0 ) feature in 10gR2(10.2.0.3)? We are migrating our OLAP database to 10g on Linux and would like to know the impacts before we do that..
How frequently Oracle performs the resize operations and how much latencies it introduces to the response time?
How do you monitor the latencies introduced by SGA resize operations? i.e. what event user session will wait ( if waits ) if resize operations are under progress?
How buggy/stable this feature is ?user4529833 wrote:

How buggy/stable this feature is ?As with all self-managing systems, there is an overhead. It is in two specific areas - monitoring and logging of the load and adjusting the parameters dynamically. You do pose an interesting question as to which metrics are available to monitor the management process. I have not dug into it, so I can not answer the question - yet. I'm just responding to highlight that it has an impact at other times as well.
Flip side - what are the performance overheads and performance losses associated with the DBA tuning (or, more likely not tuning) the SGA & PGA manually per the various workflow requirements. This is the case that the auto tuning was likely designed to tackle.
I highly doubt that the feature will be better than a crack DBA team adjusting the pools manually based on real and known workload. But I don't run into many situations where an entire crack DBA team can be assigned to proactively manage DB performance 24x7. (Thus, the feature becomes useful in spite of overhead.) -
Hi,
i've 11.2 Database.
I know that using AMM, Oracle manages sga and pga together.
But why shink and grow (sga pools) operation impact only shared and buffer and not also the pga?
An example, I've 5Gb of AMM, looking AWR, Oracle set shared pool to about 1,9Gb, buffer to 1,1Gb (sga target around 3,3Gb) and the results to PGA.
Looking Memory Dynamic Components in AWR, i see that shrink/grow operation uses only shared and buffer pool and not the PGA that is not used.
Why this?
Thanks.Mr.D. wrote:

Thanks.What I understood from your question is that you dont see reallocation of PGA as you see in SGA resizable components.
[url http://docs.oracle.com/cd/B28359_01/server.111/b28310/memory003.htm] this describes how the PGA is allocated.
Unless there is pressure on oracle to release the memory from PGA to allocate to SGA or vice versa you will not see the change in memory allocation for PGA -
Alter system set shared_pool_size extremely slow.
I am trying to increase my shared_pool_size from 60m to 200m by simply typing alter system set shared_pool_size=200m;
I did alter system flush shared_pool; before to clear out the current shared_pool.
I'm on 9i and my SGA_MAX_SIZE is 3g and I have plenty room to grow.

My event in v$session_wait is background parameter adjustment.
Any help would be appreciated. I know that I can bounce the server and let it read it from the init.ora. However, I'm trying to fix some current 4031s in my shared pool. The flush did fix them temporarily.Are you sure your instance was in the state you thought it was ? This is what you reported from show sga:

Redo Buffers 798720 bytesYou say your shared_pool_size is 60M and you want to grow it to 200M, but the Variable Size in the output above suggests that your shared pool had already grown to about 2.3 GB, so your command would have been trying to shrink it quite dramatically. (And 9i isn't very good at shrinking the shared pool because of the problems of pinned and "KEEP"ed objects in the library cache.
Things to check (from another session):
v$sga_current_resize_ops to see if your resize operation is still running, and what it's trying to do.
v$sga_resize_ops to see i f your resize operation completed some time ago - leaving your session stuck somewhere else. (There's a convenient query I wrote against this view published here: http://jonathanlewis.wordpress.com/2007/04/16/sga-resizing/ )
v$session_wait (for the resize session) to see if the session is waiting or working
v$sesstat (for the resize session) to see if it gives you any clues about current activity

Single record insert performance problems
Hi,
we have on production environment a Java based application that makes aprox 40.000 single record Inserts per hour into a table.
We ha traced the performance of this Insert and the medium time is 3ms, that is ok. Our Java architecture is based in Websphere Application Server and we access to Oracle 10g through a WAS datasource.
But we have detected that 3 or 4 times a day, during aprox 30 seconds, the Java service is not able to make any insertion in that table. And suddenly it makes all the "queued inserts" in only 1 second. That "pause" in the insertion cause problems of navigation because is the top layer there is a web application.
We are sure that is not a problem with the WAS or the Java code. We are sure that is a problem with the Oracle configuration, or some tunning action for this kind of applications that we don´t know. We first thought it could be a problem with a sequence field in the table. Also, a problem when occurs the change of the redo log. But we've checked it with our DBA and this is not the problem.
Has anybody any idea of what could be the origin of this extrange behaviour?
Thanks a lot in advance.
Jose.There are a couple of things you'd need to look at to diagnose this - As Joe says it's not really a JDBC issue from what we know.
I've seen issues with Oracle's automatic SGA resizing causing sporadic latency in OLTP systems. Another suspect would be log file sync wait events, which are associated with commits. Don't discount the impact of well meaning people using tools like TOAD to query the DB - they can sometimes cause more harm than good.
Right now I'd suggest you run AWR at 10 minute intervals and compare reports from when you had your problem with a time when you didn't. -
Hello !
Please explain
what is the key difference between processes/mechanisms the GROWING/SHRINKING of pools (sga_target<>0)
and clearing of granules (set sga_max_size and sga_target=0) ?

in 10g we've SGA_target and SGA resize operation detail is available in below view.
V$SGA_RESIZE_OPS displays information about the last 400 completed SGA resize operations. This does not include in-progress operations. All sizes are expressed in bytes.
in 11g we've memory target parameter for SGA and PGA.
V$MEMORY_CURRENT_RESIZE_OPS displays information about memory resize operations (both automatic and manual) which are currently in progress. An operation can be a grow or a shrink of a dynamic memory component. -

Resizing Shared Pool or SGA Target??
I need to resize my shared pool to 512M
I am using 10g Enterprise Edition. 10.1.0.4 on windows 2003
Do i need to bounce the db or i can do this task using alter system command w/o shutting down the db??
I believe i will hv to resize the sga_maz_size aswell...
However is it true that if i set the sga_target.. everything will be taken care of.
I am trying to upgrade Oracle EM Grid Control from the basic 10.2.0.2 to 10.2.0.5
According to the read me file, the upgrade patch requires shared pool to be a minimum of 512M.
Note : this is a development server.. hence no applications, no testing is done on it now.. as of now for the smooth install and upgrade.. please help me with correct parameter and values to do this task.
Kind regardsPlease delete one of the posts.. double posting.

Tuning of SGA on Oracle 8.0.5 and AIX 4.3.3
Hi folks,
I have an AIX box running AIX 4.3.3 and Oracle 8.0.5.2.0. The original SGA settings are as follows:
shared_pool_size = 150000000
sort_area_size = 1024876
db_block_buffer = 126102
The SGA size then is:
Total System Global Area 1838467232 bytes
Fixed Size 47264 bytes
Variable Size 803287040 bytes
Database Buffers 1033027584 bytes
Redo Buffers 2105344 bytes
I changed the SGA settings to the following:
shared_pool_size = 768000000
sort_area_size = 512000000
The SGA size is now:
Total System Global Area 2227943584 bytes
Fixed Size 47264 bytes
Variable Size 214097920 bytes
Database Buffers 2013265920 bytes
Redo Buffers 532480 bytes
After this change was done, the system ran but the users had some problems running reports in JDEOneWorld.
I then downsize the SGA settings and altered the db_block_buffer to improve buffer cache hits with these settings:
db_block_buffers = 245760
shared_pool_size = 200000000
sort_area_size = 1048576
On restarting the database with the new values, I noted that the SGA size remained unchanged as below:
Total System Global Area 2278475936 bytes
Fixed Size 47264 bytes
Variable Size 264105984 bytes
Database Buffers 2013265920 bytes
Redo Buffers 1056768 bytes
I tried to increase the size of db_block_buffers to 327680 but encountered ORA-27123 when trying to startup the database. I did some searches in metalink and found an article saying that the SGA size cannot exceed 2GB on AIX platforms. (Doc ID: 114934.1). Therefore I resize the db_block_buffers back to 245760.
What puzzles me is why the SGA size does not reflect my latest init.ora settings? Does anyone have any idea on how I can get the SGA to reflect the updated values in the init.ora file?I did a find and here are the files I got:

As I mentioned previously, my client is not prepared to perform an upgrade on both Oracle and AIX. As much as I would like to have them upgrade to the latest versions, it is just not possible.
Oracle 8.0.5 does not have spfiles, so there is no way for me to edit a spfile unless this is one of those undocumented tricks floating around. -
Dear All,
We are using Oracle 10g R2 on windows 2003.Our sga_max_size=2000m and sga_target=800m.We have enabled ASM.
I got an alert message in enterprize manger which says virtual memory paging is happening and its impact is 100%.
Now,Is this problem related to SGA?Do i have to resize my sga_max_size ?
We have 4gb RAM 460 gb hard disk what would be the ideal size for sga?
Regards,
KrisFor guidelines over SGA & memory, refer discussion here...
Re: windows 32bit sga and pga limits
But actual sizing of SGA depends on your application needs. If it needs more SGA, it does. You might need to add more RAM to your server to cope up with existing workload for a given number of users. -
We bought a server for oracle data warehousing which has got 200GB RAM. Can I set set my SGA_TARGET to 100GB. Is it true the more SGA size result in better performance.
Thaks
jeevanHi Jeevan,
I would not set sga_target, it can cause RAM thrashing . . .
In an article titled Automatic Shared Memory Management we see:
http://www.oracle.com/technology/pub/articles/10gdba/week17_10gdba.html
Some pools in SGA are not subject to dynamic resizing, and must be specified explicitly. Notable among them are the buffer pools for nonstandard block sizes and the non-default ones for KEEP or RECYCLE. If your database has a block size of 8K, and you want to configure 2K, 4K, 16K, and 32K block-size pools, you must set them manually.
Their sizes will remain constant; they will not shrink or expand based on load. You should consider this factor when using multiple-size buffer, KEEP, and RECYCLE pools.
In addition, log buffer is not subject to the memory adjustment—the value set in the parameter log_buffer is constant, regardless of the workload. ( In 10g, a new type of pool can also be defined in the SGA: Streams pool, set with parameter streams_pool_size. This pool is also not subject to automatic memory tuning.)
Is it true the more SGA size result in better performance. Yes, but it may not be much, or it could be alot! It depends.
On a dedicated server, your goal is to allocate all the RAM, without causing swapping. I have my notes here:

(10g)SGA_TARGET 파라미터를 이용한 AUTOMATIC MANAGMENT SGA COMPONENTS
제품 : ORACLE SERVER
작성날짜 : 2004-04-26
PURPOSE
이 문서는 SGA_TARGET 이라는 새로운 파라미터를 이용하여 Automatic
management SGA Components에 대하여 알아보기로 한다.
Explanation
SGA_TARGET 파라미터를 이용한 Automatic management SGA Components에 대하여
설명하기로 한다.
Automatic management SGA Components using SGA_TARGET
Oracle 10g부터 다음과 같은 각각의 SGA component에 대한 값들을 manual하게
설정할 필요가 없다.
shared_pool_size
log_buffer
java_pool_size
large_pool_size
buffer_cache_size
위 SGA 파라미터들의 사이즈를 측정하고 initSID.ora file에 그 값을 설정할
필요가 없음을 의미한다. 사실 SGA 크기를 정의하는 위 파라미터들을 설정하지
않아도 된다.
다만 10g 에서는 SGA_TARGET 이라는 새로운 파라미터만 셋팅하면 된다.
SGA_TARGET 이라는 파라미터는 해당 instance에 필요한 SGA의 최대 크기를
가리킨다.
SGA_TARGET을 152M 로 잡았다고 가정하자. 이것은 SGA가 커질 수 있는 최대 크기가
152M 라는 의미이다. Shared pool, buffer cache, large pool, java pool 과 같은
SGA component들은 이 maximum 사이즈 내에서 할당될 것이다.
오라클은 이러한 component들의 초기 값을 자동으로 계산하고 필요에 따라
자동으로 resize한다.
즉, SGA_TARGET 만 셋팅되어 있으면 shared pool, buffer cache, large pool,
java pool에 대하여 값을 명확히 지정할 필요가 없다.
Example
SGA_TARGET=152M 로 잡았다고 가정한다.(block size is 8K).
SQL> show parameter sga_target
NAME TYPE VALUE
sga_target big integer 152M
오라클은 다음과 같이 SGA component들의 사이즈를 정의한다.
SQL> show sga
Total System Global Area 159383552 bytes
Fixed Size 769328 bytes
Variable Size 72270544 bytes
Database Buffers 62914560 bytes
Redo Buffers 23429120 bytes
여기서 주목할 점은 다음과 같다.
1) SGA_TARGET을 셋팅하면 SGA_MAX_SIZE 의 값은 또한 SGA_TARGET 으로 셋팅된다.
즉, SGA_TARGET = SGA_MAX_SIZE.
SQL> show parameter sga
NAME TYPE VALUE
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 152M
sga_target big integer 152M
2) SGA_TARGET 의 값을 SGA_MAX_SIZE보다 더 크게 설정할 수 없다.
즉, SGA_TARGET <= SGA_MAX_SIZE.
SQL> alter system set sga_target=160M;
alter system set sga_target=160M
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-00823: Specified value of sga_target greater than sga_max_size

if automatic components take 180MB out of 200MB and lets say manaul components take 10M. so is the remaing 10MB wasted? yes or noWhy wasted? Only after giving memory to the manual components, whatever is left would be given to the automatic components. So nothing would be wasted by this approach.

ASMM - sga dynamic components and standby
Are SGA dynamic modifications "transferred" from the primary to the standby?
i.e: if __shared_pool is resized in primary will this also trigger standby?
Trying to determine if dynamic pools may somehow end up being different upon switchover/failover or if it's possible that upon switchover standby's dynamic shared_pool size results smaller than that of former primaryAbsolutely, yet there are some things DG broker does upon switch over. Was wondering if somehow standby would be "updated" upon switcher...
But then again, it's SGA as a hole may be smaller to begin with...
Were you to tell if the following is true or false:
"After activation standby database may have a SGA configuration different than that of primary"
what would you say?
Hole intention here is to determine whether after a switch over it's possible to start getting ORA-04031 on account of dynamic pools being different
and oracle struggling to re-size them...
Suppose we have a 6Gb SGA... primary has been working full steam for say 2 months and dynamic pools are set by oracle in the following way:
shared_pool...3Gb
cache...3Gb
Now if standby has not acknowledged those dynamic changes, it may be using values of it's own... maybe a larger cache... say
shared_pool...1Gb
cache...5Gb
Now we switch-over and if sga settings are not "synced", then new primary will have 2Gb less of shared pool...
Application kicks in, shared pool runs low... Oracle will have to move 1 or 2Gbs from cache to shared pool, this will cause serious latching and most likely ORA-04031
so is that likely to happen?
