Increasing SGA_MAX_SIZE on oracle9i 9.2.0.1
Hi All,
Can any one explain on this below request:
I am having Solaris 8 (SPARC-64 bit) on which i have installed Oracle9i 9.2.0.1(32 bit)..........
Currently am in process of upgrading it to 9.2.0.4 version and already am having database in this, which is in production environment.
As described in patch doc we should have atleast 150M size of SHARED_POOL_SIZE and JAVA_POOL_SIZE
hence am confused for increasing SGA_MAX_SIZE as am having 1 GB of RAM.
Upto what size i can increase this SGA_MAX_SIZE and also i need good performance after increasing it.
Is there any rule to assign size for SGA_MAX_SIZE???? So that i can upgrade my database by applying patch smoothly without any issues?????
PLEASE HELP ME ON THIS ISSUE
Regards,
Veeresh.(Junior Oracle DBA)

You system has only 1Gb of memory so you cannot go beyond 1GB at all
Next 1GB should be shared by OS and Database assuming nothing other than these two
Normaly unix OS uses 20 % of Memory for the OS running and will be around 30% in windows
so you are left out with 800MB atmost
800 should be shared by SGA and PGA here
Your PGA also needs memory
500+300 or
600+200
No choice here you have to go with this...Just increase and apply the patch these wont cause too much issues ..
Make sure you backup everything before doing anything

Increase SGA_MAX_SIZE and SGA_TARGET
Hi all,
I want to increase SGA_MAX_SIZE and SGA_TARGET in 10g. Currently we have
SQL> sho parameter sga
NAME TYPE VALUE
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 2384M
sga_target big integer 2384M
And we have 16GB RAM in redhat linux 4(32 bit).Oracle 10.2.0.3 DB.
Because of 32 bit OS, I was not able to increase shmmax more than 4GB.
In this situation how and how much SGA_MAX_SIZE and SGA_TARGET I can increase?
Thanks in Advance,
SunilHi sunilgln,
Given the present state of things, you have to take a meassure of how many RAM is used with nothing running but the OS, that will give you the Linux footprint.
Take note of the amount of physical free memory (using <strong>top</strong> command)
Later you have to estimate how much swapping are you willing to accept, the SGA you define may be within the ranges of
FREE MEM*90% and FREE MEM*90+(OS FOOTPRINT*%SWAP MEMORY WILLING TO USE)
<em>This is a proposal for setting this up, you need to tune and balance load depending on usage.</em>
Another recommendation, SGA_TARGET is <strong>dynamic</strong>, SGA_MAX_SIZE is not...but you may set SGA_MAX_SIZE to a full allocation and set SGA_TARGET to a percentage that allocation and gradually use it.
What happens is: the OS will "allocate" a chunk(or chunks) the size given by SGA_MAX_SIZE, but the real usage by the database will be determined by SGA_TARGET.
Hope this helps you
Ignacio

Increasing SGA_MAX_SIZE in Oracle 10.2.0.1
Hi,
we have successfully upgrade our database from 8.1.7.0 to 10.2.0.1
now in the database control, SGA max size is 524MB
i want to increase it, as to increase the size of SHARED_POOL_SIZE and DATBASE_BUFFER size
i have checked the init.ora file, in that there is no parameter mentioned as sga_max_size
from where and how to increase the SGA_MAX_SIZE in 10g version ?
with regardsHi,
Database is using init.ora file in the pfile folder
In the init.ora file i have increased the SGA_MAX_SIZE parameter to 1024Mb from 524Mb
Now, from dbcontrol screen, Automatic Shared Memory Managment is Disabled and i want to make it ENABLE
now when i click on ENABLE button, on the next page it shows total SGa size i.e 332 Mb
and further wheni click on "OK" button for ASSM configuration, it shows the error as below :-
1.) SGATargetSize - ORA-02097 : parameter cannot be modified because specified vale is invalid ORA : cannot set sga_target due to existing internal settings, see alert log for information
in the alert log , it mentions
Cannot set sga_target with db_block_buffers set
and
Alter system set java_pool_size='0' SCOPE=MEMORY;
2) sharedPoolsize - ORA-02097 parameter cannot be modified because specified value is invalid ORA-04034: unable to shrink pool to specified size
now i just mentioned the memory component details for reference :
shared pool : 104 Mb
buffer cache : 169 Mb
large pool : 0
java pool : 4 Mb
other : 54 Mb
total SGA -- 332 Mb
Maximum SGA Size -- 1024 Mb
how to make ASSM Enable ???

Want to increase Tablespace of Oracle9i in AIX
Dear Sir,
I want to increase tablespace of Oracle 9i in AIX. What command i will write for this.
With Regards,
Debasis Mishra
[email protected]thier r many ways of doing this .
U can either add a new datafile or extend the size of the datafile present.
It also depends on the way you have created the tablespace originally.
So if u can give that details it will be helpful. -
SGA_MAX_SIZE and shmmax values
All,
My environment is
Oralce - 10.2.0.4.0
Two node RAC environment
Red hat Enterprise Linux 5 64 bit operating system
RAM size - 64 GB
shmmax - 4294967295 (one byte less than 4 GB)
SGA_MAX_SIZE = 3808M
SGA_TARGET = 3808M
PGA_AGGREGATE_TARGET=1000M
When I run the ADDM, it is telling that SGA was inadequately sized, increase the sga_target to 4760M. It says that 33% impact.
In my case, I need to increase SGA_MAX_SIZE.
I may be wrong, but from google, i assume that SGA_MAX_ZIZE can't be more than shmmax. Is it true?
If I have to increase the shmax, is it fine to increase to 5 GB based on ADDM recommendataion. Are there any harm to increase the shmmax to 20GB are so for safer side?
Any relation beween shmmax and RAM size?
If I have to alter the SGA_MAX_SIZE in RAC, I need to bounce the database or i can do one instance at a time right. If I am going with one node at a time, since it is a production, what will happen to the connections in that node when i am restarting that particular instance? I have a TAF policy of "Basic".
is it like all the select statements will be moved to survival node whereas insert, update and delete transactions will be broken?
Awaiting your help..Always it is recommended to keep "shmmax" half the size of physical memory.
First you need to increase shmmax and then increase the SGA_MAX_SIZE as per ADDM.
See the below doc for all your answers answers.

Need to increase db_cache_size
Hi Forum Friends,
I have one concern, On one production server as per ADDM analysis report we need to increase db_cache_size at db level .
According to my knowledge, SGA_MAX_SIZE= db_cache_size+shared_pool size + large pool size . Pls correct if i am wrong ?
As per my DB settings:
============================================================
sga_max_size = 70G
db_cache_size = 60928M
shared_pool_size = 8G
large_pool_size= 0
sga_target= 0
As per ADDM report db_cache_size should be 64,768M
================================================================================================================
But If my above statement is correct then we cannot increase db_cache_size untill we will increase sga_max_size so that all parameter get involved in it ?
Regards,
Vishal RainaThe SGA = Fixed size + Variable size + DB Cache Buffers + Online Redo Buffers. Try querying v$sga and v$stastat to see how your space is allocated.
Also Oracle has a strong tendency to over-identify space needs, that is, just because one of Oracle's features suggests more space is needed does not mean it really is. You may be able to relieve some of the demand on the buffer cache by tuning SQL to be more efficient. Then see if Oracle still wants more space.

Do i need to increase SGA_Target of my database that colud use more memory?If your database working properly without any issues/performance, Then no need to change.
Here nothing related to SGA_TARGET, if you want to increase memory for ORACLE instance, You have to increase SGA_MAX_SIZE , Moreover this is static value, you can change either in PFILE/SPFILE but not in memory , you have to bounce the instance for immediate changes.
SGA_TARGET is dynamic, once you set SGA_MAX_SIZE, then SGA_TARGET can grow upto SGA_MAX_SIZE.

HOW INCREASE SGA IN ORACLE RAC 10 G WITH 2 NODES
How increase sga_max_size, sga_target in ORACLE RAC 10 G WITH 2 NODES;
i have oracle 10g in unix hp-ux 11i in rac (2 nodes)
with sga 8g; and i want to increase 12g;
i can alter these parameters without shutdown the entire database ?; , i can alter and take these change in one node first and later de second node?
i used in first node :
1- alter system set sga_max_size=16g scope spfile;
2- alter system set sga_targer=12g cope spfile;
later i restard all intance one by one:
srcvtl stop instance -d my_database -i my_instance1 -o immediate;
srcvtl start instance -d my_database -i my_instance1
3- in second node.
srcvtl stop instance -d my_database -i my_instance2 -o immediate;
srcvtl start instance -d my_database -i my_instance2
but my sga is the SAME 8G.. WHY NOT CHANGE...
i changed these parameters and restar my instance in first node later stop and start using srvctl the second node but my sga not change. continue in 8g ;however these changes are in spfile so;
prd2.sga_max_size=8589934592#internally adjusted
prd1.sga_max_size=8589934592#internally adjusted
*.sga_max_size=17179869184

prd1.sga_target=8589934592
*.sga_target=12884901888
prd2.thread=2
prd1.thread=1
how i can apply these change node by node or i need shutdown the entire database?
need to make these changes without affecting my application because i can not shutdown the both node...
Edited by: user568681 on 02-sep-2010 14:32Hi,
I just checked on a test RAC configuration (HP-UX, 10.2.0.4)
You don't need to stop the database.
Keep your "rolling" original scenario but change :
alter system set sga_max_size=16g scope spfile;
alter system set sga_target=12g cope spfile;by
alter system set sga_max_size=16g scope spfile sid = 'PRD1';
alter system set sga_target=12g scope spfile sid = 'PRD1';
alter system set sga_max_size=16g scope spfile sid = 'PRD2';
alter system set sga_target=12g cope spfile sid = 'PRD2';Actually
alter system set sga_max_size=16g scope spfile;
alter system set sga_max_size=16g scope spfile SID='*';changes globally the values for every instance in the spfile ("*.XXXXXX" is updated) but it does not remove the specific entries already assigned to one particular instance (and it is your case !)
Alternatively you could reset the values assigned specifically to one instance with "alter system reset" to have only "*.XXXX" for those parameters.
Best regards

I have been searching, but I have not found a reference to a problem quite like this anywhere. Any pointers to how this can be solved would be greatly appreciated.HI
1) can you post OS version?
2) antivirus/firewall enabled
3)Increase the depleted swap/memory or other resource which is logged in the OS log file
Have sufficient physical memory on Server so that you can allocate more SGA/PGA to the database.
4) Increase SGA_MAX_SIZE and SGA_TARGET so that you can accommodate following pools.
5) Restart the instance.
6) Increase INIT.ORA memory parameters and make sure following pools are set to recommended value i.e. 200M.
7) SHARED_POOL_SIZE
8) JAVA_POOL_SIZE
9) STREAMS_POOL_SIZE
there is no swap to grow stack.

Memory graphic (OEM 10g)
Hi guys,
One doubt regarding the Oracle enterprise manager and the graphics of memory utilization.
In performance tab I´m seeing memory utilization like 99% of use and swap utilization 3%
if I increase sga_max_size Will I have more memory available in this case ? This grahics shows the memory available to oracle or the full system memory ?
Oracle 10gR1
thanks,
sylari am experiencing this too. memory usage is too high (98%) and i don't know why it is happening. anybody wants to share their idea?
10gR1 on linux
thanks.

Frequent dumps with the message "LOAD_PROGRAM_LOST"
Hi,
I get frequent dumps in an SRM development server SRM.
u201CLOAD_PROGRAM_LOSTu201D is the dump.
The error analysis says this
While the program was running, the program "CL_O24AZ2T4VNGKGGI9LRCNKSPN8DNCP" had to be reloaded because a bottleneck pushed it out of the local program buffer. However, the database was found to contain an already changed program.
I thought it to be problem with program buffer.When I checked the parameters,the current value of the parameter u201Cabap/buffersizeu201D is 500MB and the available free space is 1MB.
If I increase the value, would my problem be resolved?Or would there be any other dependent parameters that I should take care.Please help.
Thanks in advance.
Regards,
Sudheer.Hi,
if you are using ORACLE, try to consuder increasing sga_max_size and db_cache_size
to set this parameter you must consider your physical memory is available.
i have experienced in the top three largest consumer goods mfg and distributor, which have huge database size and high database growth, with large number of user, currently running 400 MB in abap_buffer_size but seems running well.
hope it help you

Manually allocate SGA and PGA to a Instance?
1) Can we Manually allocate SGA and PGA to a Instance after . startup
sql>show user
connected to idle instance
2) In which type of memory user is stored in oracle mem or windows memory.
ThanxIf you are using 10g, you can modify PGA size after instance startup by alter system to change PGA_AGGREGATE_TARGET
You can't increase SGA_MAX_SIZE while instance is running. However you can change effective SGA size by alter SGA_TARGET if you are using ASMM
to find out what's current logon user,
select user from dual;
Don't quite understand your second question. -
Hi,
I need to increase SGA_MAX_SIZE & SGA_TARGET from 12gb to 18gb in Oracle 10gR2 2 node RAC database on windows 2003
Instance 1 is not getting change after changed using 'alter system set SGA_MAX_SIZE=18G scope=spfile; command. Instance 2 only increased SGA size.
both the instance reading same spfile in ASM. is there any specification for sga limit on windows 2003?
Thanks.Perhaps there is already an instance specific setting in the spfile for instance1? In that case, the command you gave will have no effect.
Maybe you are looking for

When is Solaris 10 update 9 due?
At the beginning of the year there were hints that Solaris 10 update 9 was due in around April/May, as we are now into July 2010. Is Solaris 10 update 9 due ( or Solaris 11 ) going to arrive before the end of year?
