Increase SGA size with ORA-02095.
Hi Experts,
I want to increase SGA for oracle 10G in window 2003 . however, I got error as
SQL> alter system set sga_max_size=1700M,scope=spfile;
alter system set sga_max_size=1700M,scope=spfile
ERROR at line 1:
ORA-02095: specified initialization parameter cannot be modified
SQL> alter system set SGA_TARGET=1700M scope=SPFILE;
System altered.
SQL> alter system set sga_max_size=1700M,scope=spfile;
alter system set sga_max_size=1700M,scope=spfile
ERROR at line 1:
ORA-02095: specified initialization parameter cannot be modified
Now I just increase SGA_target as 1700M How to increase SGA_MAX_SIZE?
Thanks
JIM

How to increase SGA size in Oracle 9i release 9.0.1.1.1
Hi,
We have Oracle 2000 server on a intel machine (2.8GHz processor and 2 GB RAM). Virtual memory is :- 3GB.
We have a Oracle 9.0.1.1.1 running on this machine. What are the parameters that I need to set to increase the SGA size. We want a large SGA size with enough space for shared pool.
Thanks in advance.
--MalayMalay,
First Check out the RAM utilization for the OS Kernel and remaining to the applications and then to SGA.
We have Oracle 2000 server on a intel machine (2.8GHz processor and 2 GB RAM). Virtual memory is :- 3GB.I suppose its Windows 2000 Server!!!
& What's the size of the Database?
all these things allow you to decide how "large" you can increase the SGA -
Hi,
RDBMS : 11.1.0.7.0

My question is...
As My project manager is asking to increase the SGA Size as i have 128gb RAM of server.
Maximum how much i can increase the SGA Size
It is PRODUCTION Server... Now it's running with out any issue... but so much RAM is there y can't we use....?
Please advice..
Thanks,As per the Note
Maximum SHMMAX values for Linux x86 and x86-64 [ID 567506.1]
=======================================================================
QUESTION 2
===========
What is the maximum value of SHMMAX for a 64-bit (x86-64) Linux system?
ANSWER 2
===========
Oracle Global Customer Support officially recommends a " maximum" for SHMMAX of "1/2 of physical RAM".
The maximum size of a shared memory segment is limited by the size of the available user address space. On 64-bit systems, this is a theoretical 2^64bytes. So the "theoretical limit" for SHMMAX is the amount of physical RAM that you have. However, to actually attempt to use such a value could potentially lead to a situation where no system memory is available for anything else. Therefore a more realistic "physical limit" for SHMMAX would probably be "physical RAM - 2Gb".
In an Oracle RDBMS application, this "physical limit" still leaves inadequate system memory for other necessary functions. Therefore, the common "Oracle maximum" for SHMMAX that you will often see is "1/2 of physical RAM". Many Oracle customers chose a higher fraction, at their discretion.
Occasionally, Customers may erroneously think that that setting the SHMMAX as recommended in this NOTE limits the total SGA. That is not true. Setting the SHMMAX as recommended only causes a few more âshared memory segmentsâ to be used for whatever total SGA that you subsequently configure in Oracle. For additional detail, please see Document 15566.1, "SGA, SHMMAX, Semaphores and Shared Memory Explained"
==========================================================================
Our server RAM is 128 gb.... as per the note 1/2 of the physical RAM we can assign for SHMMAX parameter... (apprx 60gb)
How can i understood this answer for my configuration......
Please advice...

HI,
EBS- 12.0.6
DB- 10.2.0.3
I found this in the ADDM Report ---
FINDING 1: 100% impact (18551 seconds)
The SGA was inadequately sized, causing additional I/O or hard parses.
RECOMMENDATION 1: DB Configuration, 100% benefit (18551 seconds)
ACTION: Increase the size of the SGA by setting the parameter
"sga_target" to 3140 M.
ADDITIONAL INFORMATION:
The value of parameter "sga_target" was "2512 M" during the analysis
period.
SYMPTOMS THAT LED TO THE FINDING:
SYMPTOM: Wait class "User I/O" was consuming significant database time.
(43% impact [7964 seconds])
SYMPTOM: Hard parsing of SQL statements was consuming significant
database time. (3.1% impact [577 seconds])
Workarround :
1. Make the entry in the pfile as sga_max_size=3500M.
2. Shutdown the DB
3. Startup the DB with the pfile
4. SQL>CREATE SPFILE='path of the spfile' FROM PFILE"
5. Shutdown Immediate
6. Startup the DB with the newly created spfile " SQL>STARTUP SPFILE='path of the spfile' "
7 sql> show parameter sga to make sure your changes takes effect
Please correct me if am wrong ..
Thanksyou have to tune the application layer , check top ten query in AWR within perfromance tab , run SQL tuning advisor for each query and see the recommendations , implemnet recommendations , as i have expericence it alls due to huge IO occuring at database (i.e Full Table Scan) due to missing index , if index is not being used then check if any function is used on index coulm (it inhabit skip index usage) then try to avoid function over index column or create function based index. You may need to run explain plan of that query or tkprof tool to identify what optimizer is taking route to fetch data.Check also stats are gathered on tables and index properly.
I have got eliminated function over indexed column by giving alternate to our techno functional consultant. -

Yogesh.Hi,
First get the backup piece size its trying to allocate for file "/home/oracle/DBBACKUP/Oracle10g1/Full_Backup/DB_Backup_201401128366598241"
= 12839996*16384
= 210370494464/1024/1024/1024
=195.9GB
Its trying to allocate ~196GB for the file.
1. Make sure the RMAN backup piece won’t exceed the O/S permitted filesize limit.
2. But we can restrict the RMAN backup piece using the MAXPIECESIZE option.
You restricted it to 120GB but actual requirement to allocate backup piece file is ~196GB.
I think you need to change the MAXPIECESIZE and give it a try.
Please update if it succeeded or failed.
Thanks & Regards,

Increasing disk size with Nw5.1 Sp8
I'm currently running a Dell SC430 with two 80gb SATA drives. The OS is Nw5.1, Sp8. I want to replace the non-system drive with a much larger one, maybe up to 1 to 2 Tb. Is there any limit in Netware on drive size? Is there any known hardware limit as well?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I believe 2 TB is the maximum size of an NSS partition, and I think you
can combine four of those for a max-size of an NSS volume (8 TB). With
that said, I doubt many NW 5.1 environments ever saw that kind of storage
and if it doesn't work then fixing it may not be fun.
Good luck.

Increase SGA on database with dataguard
hi all,
I have a database (10.2.0.2.0) configured with dataguard and we want to increase the SGA. We want update the RAM from Server ( Microsoft Windows Server 2003 R2 Server 5.2 Service Pack 2 (32-bit) ) with double memory RAM (actually 8G):
The steps would be the next?:
- SQL>alter system set sga_max_size=16G scope=spfile;
- SQL>alter system set sga_target=16G scope=spfile;
- shutdown immediate;
- startup;
Same in the standby database?
Thanks in advance.Hi;
What is your current SGA_MAX_SZE parameter? the SGA_MAX_SZE parameter is not dynamic in oracle 10g.
To increase the sga size for your instance or to decrease,
1. Make the entry in the pfile as sga_max_size=value. (generally pfile at 'ORACLE_HOME\database') *
2. Shutdown the DB
3. Startup the DB with the pfile as " SQL> STARTUP PFILE='path of the pfile edited' "
4. Your DB is now running on pfile, to make the changes in spfile "SQL>CREATE SPFILE='path of the spfile' FROM PFILE"
5. Shutdown Immediate
6. Startup the DB with the newly created spfile " SQL>STARTUP SPFILE='path of the spfile' "
7. sql> show parameter sga to make sure your changes takes effect
8. You can increase SGA_TARGET dynamicly by ALTER command.

Increasing the size of the SGA
I'm using the Oracle Enterprise Manager Database Control on a 10.2.0.4 instance running on Redhat Enterprise Linux. One of the recommendations that the AWR\ADDM always seems to give is: "Increase the size of the SGA by setting the parameter SGA_TARGET to N". I've gone through the process twice already by upping the SGA_MAX_SIZE and SGA_TARGET parameters. It's currently recommending to up it to 6176M, I have not done this yet.
(1) Is this one of the recommendations that you would ignore within the DBCA if performance of the database seemed acceptable?
(2) Why does it always come back from the AWR\ADDM as a recommendation?
(3) What SQL or performance statistics does it do to determine whether the SGA is undersized and how does Oracle determine the SGA recommended size that shows up in the ADDM feedback?
Thanks in advance...Truely new questions do deserve new threads. Questions that are a direct result of responses to the initial question should be asked on the same thread.
If there has been a time gap between the last post on the initial thread and the new question coming to mind then a new thread is probably the better choice.
To answer the question asked if the database is not suffering ORA-04031 errors and performance is OK then I would ignore the recommendation to increase the size of the SGA yet again.
What you might want to do first is reivew how the sga is being used (v$sgastat) and look for bad code technique that leads to needing memory, i.e., the use of SQL that passes constants to Oracle in what would otherwise be the same SQL statement if a bind variable was used and excessive use of Dynamic SQL when again bind variables could have been used in the SQL.

I have been using I.E. with myyahoo.com as my homepage and I started having a page freeze for 30 seconds (approx.) 5 or 6 times a session. this is powered thru ATT.net.

Yahoo/IE has a magnifying glass icon in the lower right corner that allows me to increase the print size. When I am on Foxfire the basis text size is 1/16th of an inch!

***SBJ***SGA size on 8i is static , and for increasing the size you have to make the changes in the pfile and bounce the database
First thumb rule is that your SGA should not exceed more than 40% of your PHYSICAL RAM in oracle <= 8i version. You can go around 80% from oracle 9i onwards

How do you increase the video size with a button?
I'm trying to set up a demo for a meeting. I want to show how
you can increase the size of the video.
Example:
http://video.google.com/videoplay?docid=-1532523169750528353
There are two buttons in the bottom right corner of the
player that will increase the video size.I havn't tried this but I would thinkg that this could work:
If you have a video object on your stage (the object that the video
actually plays in) you could probably make a button that simply
changes the dimensions of it such as:
setProperty("theVideoPlayer",_height, 240);
setProperty("theVideoPlayer",_width, 320);
The movie should adjust to fit the screen, however if you
make the movie larger than or a different aspect ratio than the
original, it will be blurred or distorted respectively. Make your
original movie, therefore, at the largest size you want it to be
seen. Keep the aspect ration the same always.
