SGA in Oracle 10g

The following parameters are set in prod db.
I would like to know whether oracle will take from sga_target or individual parameters in oracle 10g
You suggesting would be highlyl appreciated
(MB)
shared_pool_size =      419430400     400
large_pool_size =      16777216     16
java_pool_size =      318767104     304
db_cache_size =      536870912     512
sga_target      2315255808     2208
sga_max_size     3674210304     3504

SGA_TARGET parameter set and individual (DB_CACHE_SIZE, SHARED_POOL_SIZE, LARGE_POOL_SIZE, and JAVA_POOL_SIZE) also which one will get effectBoth! For example, if you have SGA_TARGET set to 8gb and also have set the individual parameters, their values set will act as the minimum values for them and their sum total still can't be ever more than the value set in the SGA_TARGET.

Increase SGA in Oracle 10g

Hi everyone,
I am Ann. I am not a DBA, because the main DBA and Developer is on maternity leave have to step up to look after an Oracle Application Forms and Reports and Oracle database (version 10.1).
Recently, people complaints the apps is slow.
So I open the Enterprise Manager, and check the Performance Adviser, it shows one issue
Finding          The buffer cache was undersized causing significant additional read I/O.
Impact (minutes)          5.31
Impact (%)
13.13
The recommendation is Increase SGA target size by increasing the value of parameter "sga_target" by 928 M. (there is a button Implement next to the message).
The findings path is
The buffer cache was undersized causing significant additional read I/O.
13.13
Wait class "User I/O" was consuming significant database time.     16.27
About the server, we use OpenSuse. I also log into the server as root.
Type free command to get info about memory and here is the details
borg:~ # free
total used free shared buffers cached
Mem: 6101512 6001288 100224 0 180376 4636256
-/+ buffers/cache: 1184656 4916856
Swap: 12586916 1728548 10858368
I just want to know is it safe to run the implement button to increase the SGA target size.
I know that I have to shutdown and restart the instance.
Many thanks,
Ann

You shouldn't do anything until
1. You confirm that there is, in fact, a problem
2. You determine exactly what the problem is
3. You determine the cause, or causes, of the problem
4. You identify, and rank, possible solutions to the problem
5. You test possible solutions in a dev/text environment to make sure your process works as expected.
6. You script a method to 'undo' any changes you make

So what! People always complain that apps are slow. While it's fine to take note of that don't make a knee-jerk reaction to it.
Gather more information.
1. Slow in what way? entering data? running reports? batch jobs?
2. Slow when? first thing in the morning? mid-day when all users are on the system? all the time?
3. How long has it been slow? Just started? A couple of days? a few weeks?
4. What does the main DBA say about the reported slowness? Have you called to ask? Why not? They are on maternity leave not climbing the alps or Himalayas. Call them and ask them if they were aware of reported problems.
5. Did you ask the main DBA what you should look at? Why not?
Tell us more information. What are the memory parameters now?
Open a sql*plus session and then run and post the results of

Oracle 10G and SGA

Hi,
i've a question about Oracle 10G and their SGA. When I do in SQLplus show sga, I get for example:
SQL> show sga
Total System Global Area 167772160 bytes
Fixed Size 1247900 bytes
Variable Size 58721636 bytes
Database Buffers 104857600 bytes
Redo Buffers 2945024 bytes
when finding other parameter I get always '0', this was not in other releases...
SQL> show parameter pool
shared_pool_size big integer 0
java_pool_size big integer 0
large_pool_size big integer 0
olap_page_pool_size big integer 0
SQL> show parameter db_cache
NAME TYPE VALUE
db_cache_advice string ON
db_cache_size big integer 0
It seems that I have no control over setting those parameters, I remember at installation time it gave a % of the pc memory would be used, has it something to do with that? Can you chose between the automatic SGA-management and setting it by yourself?
thanks
greets

Hi,
I also find some trace files under my udump-dir, has this also to do with the SGA?

Oracle 10G New Feature........Part 1

Dear all,
from last couple of days i was very busy with my oracle 10g box,so i think this is right time to
share some intresting feature on 10g and some internal stuff with all of you.
Have a look :-
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Oracle 10g Memory and Storage Feature.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1.Automatic Memory Management.
2.Online Segment Shrink
3.Redolog Advisor, checkpointing
4.Multiple Temporary tablespace.
5.Automatic Workload Repository
6.Active Session History
7.Misc
a)Rename Tablespace
b)Bigfile tablespace
c)flushing buffer cache
8.ORACLE INTERNAL
a)undocumented parameter (_log_blocks_during_backup)
b)X$ view (x$messages view)
c)Internal Structure of Controlfile
1.Automatic memory management
================================
This feature reduce the overhead of oracle DBA.previously mostly time we need to set diff oracle SGA parameter for
better performance with the help of own experience,advice views and by monitoring the behaviour
of oracle database.
this was just time consuming activity.........
Now this feature makes easy life for oracle DBA.
Just set SGA_TARGET parameter and it automatically allocate memory to different SGA parameter.
it focus on DB_CACHE_SIZE
SHARED_POOL_SIZE
LARGE_POOL
JAVA_POOL
and automatically set it as
__db_cache_size
__shared_pool_size
__large_pool_size
__java_pool_size
check it in alert_log
MMAN(memory manager) process is new in 10g and this is responsible for sga tuning task.
it automatically increase and decrease the SGA parameters value as per the requirement.
Benefit:- Maximum utlization of available SGA memory.
2.Online Segment Shrink.
==========================
hmmmmm again a new feature by oracle to reduce the downtime.Now oracle mainly focus on availablity
thats why its always try to reduce the downtime by intrducing new feature.
in previous version ,reducing High water mark of table was possible by
Exp/imp
or
alter table move....cmd. but on these method tables was not available for normal use for long hrs if it has more data.
but in 10g with just few command we can reduce the HWmark of table.
this feature is available for ASSM tablespaces.
1.alter table emp enable row movement.
2.alter table emp shrink space.
the second cmd have two phases
first phase is to compact the segment and in this phase DML operations are allowed.
second phase(shrink phase)oracle shrink the HWM of table, DML operation will be blocked at that time for short duration.
So if want to shrink the HWM of table then we should use it with two diff command
first compact the segment and then shrink it on non-peak hrs.
alter table emp shrink space compact. (This cmd doesn't block the DML operation.)
and alter table emp shrink space. (This cmd should be on non-peak hrs.)
Benefit:- better full table scan.
3.Redolog Advisor and checkpointing
================================================================
now oracle will suggest the size of redo log file by V$INSTANCE_RECOVERY
SELECT OPTIMAL_LOGFILE_SIZE
FROM V$INSTANCE_RECOVERY
this value is influence with the value of FAST_START_MTTR_TARGET .
Checkpointing
Automatic checkpointing will be enable after setting FAST_START_MTTR_TARGET to non-zero value.
4.Multiple Temporary tablespace.
==================================
Now we can manage multiple temp tablespace under one group.
we can create a tablespace group implicitly when we include the TABLESPACE GROUP clause in the CREATE TEMPORARY TABLESPACE or ALTER TABLESPACE statement and the specified tablespace group does not currently exist.
For example, if group1 is not exists,then the following statements create this groups with new tablespace
CREATE TEMPORARY TABLESPACE temp1 TEMPFILE '/u02/oracle/data/temp01.dbf'
SIZE 50M
TABLESPACE GROUP group1;
--Add Existing temp tablespace into group by
alter tablespace temp2 tablespace group group1.
--we can also assign the temp tablespace group on database level as default temp tablespace.
ALTER DATABASE <db name> DEFAULT TEMPORARY TABLESPACE group1;
benefit:- Better I/O
One sql can use more then one temp tablespace
5.AWR(Automatic Workload Repository):-
================================== AWR is built in Repository and Central point of Oracle 10g.Oracle self managing activities
is fully dependent on AWR.by default after 1 hr, oracle capure all database uses information and store in AWR with the help of
MMON process.we called it Memory monitor process.and all these information are kept upto 7 days(default) and after that it automatically purge.
we can generate a AWR report by
SQL> @?/rdbms/admin/awrrpt
Just like statspack report but its a advance and diff version of statspack,it provide more information of Database as well as OS.
it show report in Html and Text format.
we can also take manually snapshot for AWR by
BEGIN
DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
END;
**The STATISTICS_LEVEL initialization parameter must be set to the TYPICAL or ALL to enable the Automatic Workload Repository.

Benefit:- Now DBA have more free time to play games.....................:-)
Advance version of statspack
more DB and OS information with self managing capabilty
New Automatic alert and database advisor with the help of AWR.
6.Active Session History:-
==========================
V$active_session_history is view that contain the recent session history.
the memory for ASH is comes from SGA and it can't more then 5% of Shared pool.
So we can get latest and active session report from v$active_session_history view and also get histortical data of
of session from DBA_HIST_ACTIVE_SESS_HISTORY.
v$active_session_history include some imp column like:-
~SQL identifier of SQL statement
~Object number, file number, and block number
~Wait event identifier and parameters
~Session identifier and session serial number
~Module and action name
~Client identifier of the session
7.Misc:-
========
Rename Tablespace:-
=================
in 10g,we can even rename a tablespace by
alter tablespace <tb_name> rename to <tb_name_new>;
This command will update the controlfile,data dictionary and datafile header,but dbf filename will be same.
**we can't rename system and sysaux tablespace.
Bigfile tablespace:-
====================
Bigfile tablespace contain only one datafile.
A bigfile tablespace with 8K blocks can contain a 32 terabyte datafile.
Bigfile tablespaces are supported only for locally managed tablespaces with automatic segment-space management.
we can take the advantage of bigfile tablespace when we are using ASM or other logical volume with RAID.
without ASM or RAID ,it gives poor response.
syntax:-
CREATE BIGFILE TABLESPACE bigtbs
Flushing Buffer Cache:-
======================
This option is same as flushing the shared pool,but only available with 10g.
but i don't know, whats the use of this command in prod database......
anyway we can check and try it on test server for tuning n testing some query etc....
SQL> alter system flush buffer_cache;
System altered.
++++++++++++++++++
8.Oracle Internal
++++++++++++++++++
Here is some stuff that is not related with 10g but have some intresting things.
a)undocumented parameter "_log_blocks_during_backup"
++++++++++++++++++++++++
as we know that oracle has generate more redo logs during hotbackup mode because
oracle has to maintain the a complete copy of block into redolog due to split block.
we can also change this behaviour by setting this parameter to False.
If Oracle block size equals the operating system block size.thus reducing the amount of redo generated
during a hot backup.
WITHOUT ORACLE SUPPORT DON'T SET IT ON PROD DATABASE.THIS DOCUMENT IS JUST FOR INFORMATIONAL PURPOSE.
b)some X$ views (X$messages)
++++++++++++++++
if you are intresting in oracle internal architecture then x$ view is right place for getting some intresting things.
X$messages :-it show all the actions that a background process do.
select * from x$messages;
like:-
lock memory at startup MMAN
Memory Management MMAN
Handle sga_target resize MMAN
Reset advisory pool when advisory turned ON MMAN
Complete deferred initialization of components MMAN
lock memory timeout action MMAN
tune undo retention MMNL
MMNL Periodic MQL Selector MMNL
ASH Sampler (KEWA) MMNL
MMON SWRF Raw Metrics Capture MMNL
reload failed KSPD callbacks MMON
SGA memory tuning MMON
background recovery area alert action MMON
Flashback Marker MMON
tablespace alert monitor MMON
Open/close flashback thread RVWR
RVWR IO's RVWR
kfcl instance recovery SMON
c)Internal Structure of Controlfile
++++++++++++++++++++++++++++++++++++
The contents of the current controlfile can be dumped in text form.
Dump Level Dump Contains
1 only the file header
2 just the file header, the database info record, and checkpoint progress records
3 all record types, but just the earliest and latest records for circular reuse record types
4 as above, but includes the 4 most recent records for circular reuse record types
5+ as above, but the number of circular reuse records included doubles with each level
the session must be connected AS SYSDBA
alter session set events 'immediate trace name controlf level 5';
This dump show lots of intresting information.
it also show rman recordes if we used this controlfile in rman backup.

Oracle 10g on HP-UX, Terrible Poor Performance!!

Hi All,
I setup an Oracle 10g on HP-UX 11iv1. Server is a HP 9000, 4 CPUs (750
MHZ). It is connected to Disk System 2405 (Virtual Array 7110). Fiber
Channels are connected at 2 GB speed.
I installed a cluster 10g database. First I installed CRS and after
that I installed oracle database. ( I want to test clustered database
with one instance)
I installed every thing line by line as oracle document wrote.
All the things, kernel parameters, patches, are like oracle wrote in
its document.
I installed Golden quality package June 2004.
I increased shmmax to 2.3 G . My SGA is 1.7 G And change some other
parameters as Sandy Gruver wrote in Best Practices for Oracle on HPUX.
I used oracle new storage system called ASM for this case.
When I put the system under the load, I was monitoring the system
carefully.
I started gmp. When we sent some quarries to database (It is not heavy
load, I tested it with a Linux system on proliant ML570 without any
problem), suddenly DISK section in gpm changed to red (critical ) I
read the warning. It said "Disk bottleneck probability = 100%". I
changed the output of disk report to "Report IO by Disk"
"DISK%" was 100% and "RAW IO RT" was about 1000 for two disks ( This
two disks dedicated for ASM). In this situation CPU idle time was 1% or
2% for all the CPUs but load average was about 1. Performance is not
acceptable at all ( In comparison with Oracle that installed on Linux).
Glance reported Disk was in Critical situation.
I think the problem is IO or something about Disks
I used HP Disk System 2405. Fibber channels on both server side and
Disk Array side are configured at 2 Gb and topologies are
PTTOPT_FABRIC.
Is it ok that RAW IO RT about 1000 for each LUN?
Why Disk% in glance/report IO BY Disk/ was 100%?
I found an error in STM logs about I/O.It said:
Entry type: I/O error
Product: Fiber Channel Interface
Logger: td
It logged this error about 12 times during the test.Any comment?
Regards,
Hasan

Sorry, I have not a solution for your problem, but similar things happen on our installation on Solaris 5.8 with Oracle 10:
I have a banking business solution from Windows/SQL Server 2000 to Sun Solaris/ORACLE 10g migrated. In the test environment everything was working fine. On the production system we have very poor DB performance. About 100 times slower than SQL Server 2000!
Environment at Customer Server Side:
Hardware: SUN Fire 4 CPU's, OS: Solaris 5.8, DB Oracle 8 and 10
Data Storage: Em2
DB access thru OCCI [Environment:OBJECT, Connection Pool, Create Connection]
Depending from older applications it's necessary to run ORACLE 8 as well on the same Server. Since we have running the new solution, which is using ORACLE 10, the listener for ORACLE 8 is frequently gone (or by someone killed?). The performance of the whole ORACLE 10 Environment is very poor. As a result of my analyse I figured out that the process to create a connection to the connection pool takes up to 14 seconds. Now I am wondering if it a problem to run different ORACLE versions on the same Server? The Customer has installed/created the new ORACLE 10 DB with the same user account (oracle) as the older version. To run the new solution we have to change the ORACLE environment settings manually. All hints/suggestions to solve this problem are welcome. Thanks in advance.

How to configure Oracle 10g to use 4GB memory

I'm trying to configure Oracle 10g to use >4GB memory. Have configured server boot.ini with required flags (/3GB /PAE). Rebooted server then created standard database, then connected to db instance and changed oracle parameters DB_BLOCK_BUFFERS, USE_INDIRECT_DATA_BUFFERS as required. Restarted DB instance, DB fails to restarted with SGA memory error. According to oracle user docs the SGA is nolonger in effect due to previous settings. Can you provide example of SPFILE with parameters settings that do work and use >4GB memory. Current server has 8GB, 2 x Dual XEON core/processors (i.e. 8 processors)

The recommended /3GB switches in the boot.ini file can only be used with the following operating systems editions (KB article 291988):
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Data Center Server
Microsoft Windows Server 2003, Enterprise Edition
Microsoft Windows Server 2003, Data Center Edition
Microsoft Windows Small Business Server 2003
Important: Windows 2000 and 2003 Server Standard Editions DO NOT SUPPORT /3GB Switch.
So if your OS is listed above, then you cannot have a larger SGA.

Ora-00604 while installing Oracle 10g on Windows XP SP2

I was installing Oracle 10g on Windows XP but the dbca was failling. So I tried to create a database manually.
But every time I launch this:
"SQL> startup nomount pfile="C:\oracle\product\10.2.0\admin\XP10G\scripts\initXP10G.ora";"
I always had:
ORA-00604: error occurred at recursive SQL level 1
ORA-02248: invalid option for ALTER SESSION
I tried to change some memory value in the init*.ora without more success.
So if anyone has been had such issue; he would be an help for me.

Oracle 10g on SuSE 9 with kernel 2.6.4

Hi,
i have installed Oracle 10g on SuSE 9 Professional with kernel 2.4.21-192 and it works fine.
For testing purposes i have installed a 2.6.4 Kernel and get the following error on database startup:
SQL> Connected to an idle instance
SQL> ORA-27125: unable to create shared memory segment
Linux Error: 1: Operation not permitted
SQL> Disconnected
Do you have any hints or is the kernel 2.6 not supported.
Thanks Klaus

/* using strace I have narrowed this down to the shmget call for allocating SGA memory. Specifically 2.6 kernel generates a WAIT in this call and Oracle specify IPC_NOWAIT flag, hence the failure condition.*/

Oracle 10g for MacOSX's memory limitation

Why is there a 1GB of SGA limit for Oracle 10g on MacOSX?
Does anybody know?

Its an oracle code limitation. They have it as a bug and commited to us that they'll remove it with 10.1.0.4 release . But haven't given us a date yet.

What is the role of Lns process in oracle 10g data guard

Hi ,
plz help me out to find out the actual working of lns process in oracle 10g data guard
when i use SYNC redo transport
the output of v$managed_stanbdy is like that ..
PROCESS PID STATUS CLIENT_PROCESS GR# SEQ#
ARCH 9258 CLOSING ARCH 2 498
ARCH 9260 CLOSING ARCH 1 499
ARCH 9262 CLOSING ARCH 2 496
ARCH 9264 CLOSING ARCH 1 497
LGWR 9206 CLOSING LGWR 2 482
its not display any info about lns,thats means lns is not working in SYNC redo transport mode ?
but if i changed it to ASYNC then the out put of v$managed_stanbdy is like this ..
PS PID STS CPS GR# SEQ#
ARCH 9258 CLOSING ARCH 1 509
ARCH 9260 CLOSING ARCH 2 510
ARCH 9262 CLOSING ARCH 1 505
ARCH 9264 CLOSING ARCH 2 508
LGWR 9206 CLOSING LGWR 1 503
LNS 10528 CLOSING LNS 2 510
Now it display all the info about lns process...
i read in oracle documentation that lns process send redo data from primary,( through network service ) to RFS on standby side.
but first output means that lns is not working,if not then which process send redo from primary to RFS on standby ?
i also read in some blog that lgwr use some extra buffer size from primary db SGA ,to write redo in that buffer ,ans lns read redo from that buffer and send it to RFS on stanby side,
i m totally confused ..can u plz help me with correct logic behind this .
thanx in advance.

Hello,
On the primary database when you run the v$managed_standby, it shows up the LNS process as this process sends redo info to the standby database and on the standby database the RFS process receives the redo information.
So on the primary database when you query the v$managed_standby, it shows up LNS and on the standby database when you query the v$managed_standby it shows up RFS. Please let us know where you are running the query.

Oracle 10g - Database does not respond to the application users

Hi all,
I am using ORACLE 10g database with 75 users connections 50 local and 20 remote users using ADSL and dial up modem. Operating system on server is
Windows 2003.
All of a sudden users making the entry get disconnected getting the error as
ORA-12516: TNS:listener could not find available handler with matching protocol stack
Other case users when using the appliaction get their PC hanged and connection
to oracle fails again. they cannot login to the application that time, the error is
ORA-04031: unable to allocate %s bytes of shared memory ("%s","%s","%s","%s")
Twice a day the users trying to login cannot access the database server.
Front end application is in VB using exe file. When the users cannot logon
to the database. I manually stop the ORACLE services(including DB console) and
then stop the listener.
This practice is going on since last two months.
Server Scenario
After Installing Oracle Standard Edition 10g.
System tablespace utilization is 98.5% which is 465 MB out of total 470 MB.
There is only one Rollback Segment named as SYSTEM.
when we install 9i 4 rollback segments as RO1, RO2, RO3, RO4 are created
by default.
Do I need to add the datafile to SYSTEM table space as its current usage is 99.15% and its auto extend is ticked on using auto extent as 10 MB. I tried adding another datafile during weekend downtime. when I resumed on saturday morning I found it did not add any datafile which I had put on thursday eveninig as system02.dbf.
Do I need to add a new datafile to the SYSTEM tablespace ?
Do I need to create new rollback segments apart from SYSTEM rollback segment ?
My current schema size 15360Mb with its usage as 9.32% (1432.25 Mb).
Please reply !!!

Currently AUTOEXTEND is ticked as on for SYSTEM tablespace and its size is showing as 99.16% (466.06 mb) used which is very much nearing to its full capacity of 470 mb.
Currently 75 users - 50 Local users and 20 Remote Users are connected to the server. Is there any limit that Server should have limited connections.
Server has Windows 2003 Standard Edition. Has Windows 2003 anything to do

in addition you might want to trace the session to find out what it is waiting for. In 10g you can use the DBMS_MONITOR package to enable the tracing, and then use the "tkprof" utility as outlined in the article to get the trace file generated analyzed.
You can also use the V$SESSION view (BLOCKING_SESSION_STATUS, BLOCKING_SESSION, BLOCKING_INSTANCE) to find out if the session is blocked for any reason, although it shouldn't consume CPU in that case.
