Sort_area_size & hash_area_size on 10g

I am confused as to whether I need to have sort_area_size and hash_area size set in my 10.2.0.3 database. I know the Oracle documentation states the following:
"Oracle does not recommend using the SORT_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead." This is the same statement made for hash_area_size as well.
I have SHARED_SERVERS set to 1. So do I need to have sort_area_size and hash_area_size configured? Or will pga_aggregate_target take over anyway?
And does anyone have any suggestions on sizing pga_aggregate_target?
Oracle Doc says 20% of SGA. And I have seen recommendations where SGA should be sized 60-80% of total memory. Seems extreme.

It is extreme. The SGA can be anywhere from 5% - 50% of the total memory depending on the size of memory, size of the database, type of database application (OLTP, Warehouse, DSS, OLAP), and user load.
What else is on the machine besides the database is a big factor in how much memory can be allocated.
Metalink has documents on sizing the SGA. You can size the PGA based on the expected concurrent user session count X an average memory per user + some extra for the unusual. How much memory you need per user depends on the application code tool set and coding stype.
It is a bit of a guessing game. I like to start small but probably adequate allocation and add more resource as the load grows based on statistics.

Oracle Performance Tuning

Hi,
Our organization recently also encounter Oracle DB performance issue, whereby I am searching for information for us to going into diagnostic the problem and finding the root cause of this performance problem.
I had read through this old article where I found a number of points being highlighted was a good start for us, and just about this port, we would like to understand what in details of AIX 5.3 and asynch I/O turned-on had to do with Oracle DB performance, unfortunately the URL given in the article (possible due to the twas back in 2006), is no longer valid (http://www.oracle.com/technology/pub/articles/lewis_cbo.html), I tried that but the pages being redirected to (http://www.oracle.com/technetwork/articles/index.html).
May I know, would you able to provide me the new URL path for the mentiened AIX 5.3 asynch I/O turned-on related information?
Our environment:
1) OS AIX 5.3
2) Oracle DB 10g
(If I have the AWR Report, would it be better possition for you to help us?)
Thank you in advanced.
Best Regards,
KaiLoon Kok

Hi,
performance tuning is a very large argument and the causes of degradation may be many.
There are several consideration that You have to do like:
- which kind of application is running on the DB
- which kind of optimizer is used
- the striping of the data files across the disks
- the dimension of the DB block
- the waits that DB encounters
- many other things like SORT_AREA_SIZE, HASH_AREA_SIZE, etc.
To begin Yr analysis use the utlbstat.sql and utlestat.sql scripts provided in the $ORACLE_HOM/rdbms/admin directory and check the conditions of the DB.
Increasing the SGA, like You've done, may not be the solution, somtimes it may instead decrease the overall performances.
Also check in wich case the DB is slow, ex. executing some particular procedure, excuting a particular query, ....
Try to identify the better the DB and then try to resubmit Yr problem.

What to check in my query running slow

Hi,
Our 11g database was migrated from one platform to another. A query which ran very quickly before on the source platform now takes ages to run on the target platform. Please could you point me in the right direction as to what things I should check to fix this problem?
thank you

Hi,
Following are the areas which can be explored. I hope this will help you.
1) Check the Explain plan for both servers. I hope you know how to gahter the explain plan for quries. Its better to use dbms_XPLAIN
-Most probably your explain plan will be different..
2) Check the init parameters of source and target tables
3) check the optimizer parameters of source and target tables. Parameters like optimizer_ind_cost_adj,sort_area_size,hash_area_size,Optimizer_mode,cursor_sharing etc
4) check the data volumn of source and target tables.
5) Check the statistics of source and target tables. Its cumbersome to compare the statistics of source and target. So what you can do is
a) Take the export of statistics of target tables
b) Import those statistics to source tables(Before importing take the backup of source table statistics)
c) Once done the check the explain plan, it should be the same like target database.
-If step 2 confirms that statistics is the problem then you should take the export of source table statistics and import in target to get the same explain plan.

Setting pfile

hello,
I am a junior DBA and iam working at production site i have some doubts regarding
pfile settings
My database configuration is ORACLE 9i:(WINDOWS)
As far as i know
for setting PFILE for WINDOWS OS we should allocate 20% of RAM
And the Remaining 80% is for ORACLE.
In this 80% for PGA
PGA=noofsessions*(2mb + sort_area_size + hash_area_size)
Assume my RAM is 1024m
In thus 20% for OS i.e 205M
Remaining 820M for ORACLE
in this for PGA(Assume that 20 sessions are opening)
PGA=20*3.5
PGA=70M
Now for SGA 750M
Does my Estimation is correct or not can u please suggest the above urgent
Regards,
Vamsi

I don't know where you get this stuff.
The recommendation is usually stated as being: your SGA in total should amount to no more than 50% of the physical RAM on the server, assuming your instance is the only instance running on that server. The other 50% is left 'spare' for the Oracle PGA and the operating system itself (I will say in passing that Sybrand's assertion that Windows will use 50% of the RAM on a box by design is... well, it's not something I have ever seen happen. Right now, I'm running on a 4GB box and Windows is consuming 1.01GB, which is 25%).
If you know ahead of time that you are going to have few concurrent users on your database, then it's a bit daft to reserve most of the 'spare' 50% for their PGAs, and you could probably usefully reduce the PGA allocation and increase the SGA allocation.
The calculations you quote I've seen before and they're not completely off the planet, but they're seriously out of date. These days, you set PGA_AGGREGATE_TARGET, not "sort_area_size" or "hash_area_size", and you let Oracle sort it out from there (well, that's the official recommendation, though the ...area_size parameters can still be set if you have to -and since you're stuck on 9i, maybe you have to).
The essence of what you post is therefore sort-of correct: the RAM on your server has to be divided between the OS, the SGA and the PGA. The OS component can be regarded as more-or-less fixed, and 20% is at least in the right ball-park. If you have lots of concurrent users, the PGA component probably needs to be increased; if you have few, it can be decreased and the balance given back to the SGA.
It's a pretty rough-and-ready way to tune things, of course. But it's at least a starting point. Just don't get hung up on specific numbers or false degrees of precision. You can't plug numbers into a formula and get perfect results for this sort of thing. You have to be prepared to tune properly after an initial guesstimate based on the formula results.

SORT_AREA_SIZE and HASH_AREA_SIZE

Guys,
Could someone explain the purpose of altering the SORT_AREA_SIZE and HASH_AREA_SIZE database parameters?
I had come across the following lines of code in one of my new application's package.
ALTER SESSION SET WORKAREA_SIZE_POLICY = MANUAL;
ALTER SESSION SET SORT_AREA_SIZE =xxx;
ALTER SESSION SET HASH_AREA_SIZE =yyy;
Thanks,
Bhagat

Thank you Sankar!
I've to perform ETL operation whereby it extracts data from a remote datasource,does sorting and loads into our database which involves huge amount of hash and sort.
So,I'm wondering how to dynamically set the value of either SORT_AREA_SIZE or HASH_AREA_SIZE or PGA_AGGREGATE_TARGET.Since our database is in 9i,I understand that adjusting the PGA_AGGREGATE_TARGET parameter would do the job for me.
I've read in an article that
The DBA may wish to consider dynamically changing the pga_aggregate_target parameter when any one of the following conditions are true:
Whenever the value of the v$sysstat statistic “estimated PGA memory for one-pass” exceeds pga_aggregate_target, the pga_aggregate_target should be increased.

Help needed for hash_area_size setting for Datawarehouse environment

We have an Oracle 10g Datawarehousing environment , running on 3 - node RAC
with 16 GB RAM & 4 CPUs each and roughly we have 200 users and night jobs running on this D/W .
We find that query performance of all ETL Processes & joins are quite slow .
How much should we increase the value of hash_area_size parameter for this Datawarehouse environment ? This is a Production database, with Oracle Database 10g Enterprise Edition Release 10.1.0.5.0.
We use OWB 10g Tool for this D/W and we need to change the hash_area_size to increase the performance of the ETL Processes.
This is the Oracle init parameter settings used, as shown below : -
Kindly suggest ,
Thanks & best regards ,

DOUBT REGARDING SORT_AREA_SIZE

Hello,
me a Jr.Dba when i executed a large query which contains indexes so many
disks sorts are happening.so i wan't to increase the SORT_AREA_SIZE.
If i wan't to increase BUFFER_CACHE_SIZE i simply take the assistance of
V$DB_CACHE_ADVICE to know what is the next efficient value for BUFFER_CACHE_SIZE .
like the above is there any thing else for SORT_AREA_SIZE ,i am not gettitng
how much i should increase the parameter SORT_AREA_SIZE.Can u plz assist me on this
Regards,
Vamsi

Hi user581473,
if you are running on 9i and above SORT_AREA_SIZE will not be effective at all as long as you have not set WORKAREA_SIZE_POLICY to MANUAL.
It defaults to AUTO!
As of 9i we have PGA_AGGREGATE_TARGET which is used a pool for PGA memory needed for workareas.
Only if you set this to MANUAL the paramteres SORT_AREA_SIZE, CREATE_BITMAP_AREA_SIZE and HASH_AREA_SIZE will be effective.
Otherwise the optimizer thinks that every sorting can get 5% of PGA_AGGREGATE_TARGET for serial and 30% for parallel execution for the sorting in memory and create an execution plan based on this assumption.
This applies only to dedicated servers in 9i and to shared servers as well as of 10g.
If you are running a large operation you should set WORK_AREA_SIZE_POLICY to MANUAL on session level and also adjust your AREASIZE parameters for this session.
So the reports and batch jpobs use manual PGA management and all the others (OLTP) can use the default.
Hope it helps,

Sounds like an improperly installed reposity
Try these instructions. This is set to my pc so youwill have to adjust to yours.
After you install the IDS 10G in a new oracle home on the Client windows PC you will find the intall manual under:
start - programs- Oracle Developer Suite - Designer documentation - Repository instalation Guide
The following are the step I use to build a new repository
You will need to set paths and names as you desire for your local PCs and repostiory.
-- Step 1
Log on as SYS
This is so you can get the path name of your datafiles:
select file_name, tablespace_name from dba_data_files;

size 12000k
default storage (initial 100k next 100k minextents 1 maxextents UNLIMITED pctincrease 0);
-- Step 2
Make sure you ave plenty of space in your system tablespace
select tablespace_name, sum(bytes)/1024/1024 from dba_free_space
group by tablespace_name;
alter tablespace system add datafile
'D:\ORACLE2\PRODUCT\10.2.0\ORADATA\ORCL1022\system03.dbf' size 140m;
-- Step 3
As SYS
create user owner identified by owner default tablespace users
temporary tablespace temp;
Run this file as SYS
@ D:\Designer_Home\IDS10_1_2\repadm61\UTL\CKROROLE.SQL
GRANT EXECUTE ON DBMS_LOCK TO owner;
GRANT EXECUTE ON DBMS_PIPE TO owner;

GRANT ck_oracle_repos_owner to owner;
GRANT CONNECT, RESOURCE TO owner;
GRANT dba TO owner;
(If you want Row Level Security (RLS) on)
GRANT execute on dbms_rls to owner;
-- Step 4 Adding a user
create user user65 identified by user65 default tablespace users

GRANT CONNECT, RESOURCE TO user65;
GRANT CKR_OWNER TO USER65;
GRANT CREATE TABLE TO user65;
GRANT CREATE VIEW TO user65;

GRANT SELECT ON SDD_GLOBAL_NAMES TO USER65;
GRANT EXECUTE ON JR_UTIL TO USER65;
GRANT EXECUTE ON JR_SYSTEM_UTIL TO USER65;
GRANT EXECUTE ON CKMIGFUN TO USER65;
-- Step 5
The following are the recommended minimum settings.
optimizer_mode = Choose
compatible = 9.0.0 # for an Oracle9i database
compatible = 8.1.7 # for an Oracle8i database
max_enabled_roles = 30
sort_area_size = 262144
sort_area_retained_size = 65536
hash_area_size = 1048576
optimizer_index_caching = 50
optimizer_index_cost_adj = 25
shared_pool_size = 32000000

db_file_multiblock_read_count=32 # for a 2K Oracle block size
db_file_multiblock_read_count=8 # for a 8K Oracle block size
Step 5b - (Oracle 9i or 10.2 DB) Install Oracle 9i or 10.2 Import and Export Utilities
Before installing Designer Repository on an Oracle 9i or 10.2 database, you need to set up the installation workstation to use the Oracle 9i or 10.2 import and export utilities. To do so, perform the following steps at the workstation from which you will be running the repository installation:
From the Oracle 9i or 10.2 installation media, install the Oracle 9i or 10.2 import and export utilities in a dedicated Oracle home.
In the Windows Registry, locate the key named:
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_HomeName\REPOS61
where HOMEn is the home number of the home installed into for a multiple Oracle home environment, but is not present where the default Oracle home is being used.
Change the value of the EXECUTE_IMPORT and EXECUTE_EXPORT variables to point to the new Oracle home. Thus, if the new Oracle home is d:\des_9i, the settings would be:
d:\des_9i\bin\exp.exe
d:\des_9i\bin\imp.exe
-- Step 6
Log on to the Repository Admin Utility of Designer
start - programs- Oracle Developer Suite - Designer - Repository Admin Utility
Install Repository button
Make sure both check boxes are checked(one is grayed out) Next
Select the proper tablespace for the seletced box
Start the install.

How do i know if my query using SORT_AREA_SIZE   or temporary tablespace ?

Good Morning Everyone !
My DB version is 10.2.0.1
I have large table exactly 3 million records.
SQL> select count(*) from tab1;
COUNT(*)
   300000
SQL> select * from tab1 order by no DESC;
sorting ... in process
300000 rows selected.
in Terminal 2 : I tried to find sorting details -   ( No rows selected - why ? )
SQL> select USERNAME , USER , TABLESPACE , SQL_ID from v$tempseg_usage ;
no rows selected
SQL> /
no rows selected
When i google i have seen this ;
If Oracle cannot do the sort in memory (SORT_AREA_SIZE initialisation parameter), space will be allocated in a temporary tablespace for doing the sort operation.
REF_LINK : TEMPORARY Tablespaces and TEMPFILES | Oracle FAQ
MY DOUBT QUESTION :   How do i know if my query using SORT_AREA_SIZE or temporary tablespace ?
Thanks in advance.

@ JohnWatson
I have seen some articles from ORA - FAQ. Good.
SQL> select USERNAME , USER , TABLESPACE , SQL_ID from v$tempseg_usage;
USERNAME                       USER   TABLESPACE                      SQL_ID
   SCOTT                               SYS          TEMP                            fh9vqgyd6m0d1
PGA management means that sorting only 300000 rows may well occur in memory
            Is this (3 million rows) - standard value for 10g version ?
Thanks JohnWatson

Problem using template in database configuration assistant Oracle 10g

Hi,
I created a database using the database configuration assistant for Oracle 10g on a Windows Server 2003 box. The database I created worked perfectly, and I had saved it as a template so I could save some time when creating similar databases (which I have to do on occasion)
When I try to use the template though, I get an error (at about 4% through the database creation) saying:
ORA-01501: CREATE DATABASE failed
ORA-09314: sltln: error translating logical name
I'm creating this new database on the same server as the one I created my previous database on and NOTHING has changed on it, I did this just minutes apart and can duplicate it at will (just try and use a template)
Heres the template file contents (KM1.dbt)

How to set sort_area_size

hello
I’m dealing with a query in which almost 100 inner joins involved. I will post query if needed. Basically it is insert statement but I run only it selection part it take 40 minutes. When I run ASH REPORT during execution I found direct path read temp, direct path write temp in top user event , buffer busy waits, control file sequential read,. I’m using 11g with automatic memory management 9Gb assign to memeory_target, and memeory_max_target,. My workarea_size_policy is auto and sort_area_size
is default 64k. all sory take palce in temp almost 10 to 15 GB temp use when I executes this select statement. I know it is very difficult to sorry all in memory but it should not done all in temp. I wanted to change workarea_size_policyto manual and set sort_area_size. What would be the size of sort_area_size ? I was reading a BOOK of Jonathan Lewis COST based oracle fundamental in which he told us the way to sizing the sort_area_size. But he did not show how he calculated this size and he did only for one table in my case five table join with one table. How I calculate size
Here is John Example
After using the dbms_stats.gather_table_stats procedure, I can check view user_tables
to confirm that the table fills 2,753 blocks, and holds 1,048,576 rows with an avg_row_len of
14 bytes, and that the avg_col_len for column sortcode is 7 bytes (the v2, v3 columns are there
simply to avoid the possibility of some funny boundary conditions appearing). These 7 bytes
include the 1 byte that holds the column length itself, so we can work out that the total volume
of data sorted must be 6MB, and that my memory allocation of 1MB is not going to be sufficient
for an in-memory (optimal) sort.

What would be the size of sort_area_sizeIn 11g you can check for a long running query in V$SQL_PLAN_MONITOR how much memory each workarea execution consumed (just to check if your automatic workarea_size_policy seems to be an issue).
You can run your query with DBMS_XPLAN.DISPLAY_CURSOR get the estimated memory requirements for optimal and single pass executions in the columns "OMem", "1Mem" and "Used-Mem" of the DISPLAY_CURSOR output.
More information about using the DISPLAY_CURSOR function properly can be found here:

http://rwijk.blogspot.com/2008/03/dbmsxplandisplaycursor.html
Christian Antognini points out that the TEMPSEG_SIZE information of DISPLAY_CURSOR is using the wrong units: http://antognini.ch/2009/05/wrong-information-about-temporary-space-usage/

Note 830576 - Parameter recommendations for Oracle 10g

hi all DBA experts.
I am not good familiar with Oracle database while i read a Note 830576 - Parameter recommendations for Oracle 10g. in which SAP General Recommendation:
You should delete obsolete initialization parameters from the profile.
To determine which obsolete parameters are currently set, proceed as follows:
SQL> SELECT NAME FROM V$OBSOLETE_PARAMETER WHERE ISSPECIFIED = 'TRUE';
when i execute above command then result is no rows selected
while there are many parameters in above SAP Note which are already obsolete and not set in initSID.ora file.
for exp. the parameter OPTIMIZER_INDEX_COST_ADJ is showing
#### OPTIMIZER MODE
#optimizer_index_cost_adj = 10
as you know that this parameter is very important regarding System Performance.
now please guide me . I have to set these parameter or no need while there is not showing any parameters against obsolete command.
waiting you valuable reply.
Regards,

hi both,
thanks for knowledge sharing with me other SDN users,
Dear Orkun,
Ok. At this stage, I can recommend you that apply what they have suggested,
in the message. So, you already did a part of it by configuring
Oracle parameters, already.
SAP support sent me this file (PRD_Parameters)

Oracle 9i & 10g replicated to MSSQL 2005 Enterprise: Problem !

Hi,
I have been doing some oracle 9i and 10g Replication to MSSQL 2005 Enterprise Database using the SQL 2005 Server Enterprise replication tool. This is working great, however, we recentrly had some problems on the Oracle side getting errors on new connection for both 9i and 10g servers. Only restarting the server has solved the problem so far....
The complete procedure to to this setup is available on Microsoft Technet:
http://www.microsoft.com/technet/prodtechnol/sql/2005/technologies/repl_quickstart_for_oracle.mspx
If anyone could help me regarding the problem on new connections problem I would appreciate
Here are the errors we are getting:
10g Agent connection Error on the Database 10g:
Timestamp=Jul 4, 2008 2:29:03 PM EDT
Severity=Critical
Message=Failed to connect to database instance: ORA-12518: TNS:listener could not hand off client connection (DBD ERROR: OCIServerAttach).
10g Agent connection Error on the Database 9i:
Timestamp=Jul 10, 2008 10:51:16 AM EDT
Severity=Critical
Message=Failed to connect to database instance: ORA-04031: unable to allocate %s bytes of shared memory ("%s","%s","%s","%s") (DBD ERROR: OCISessionBegin).
Notification Rule Name=Send Email For Database Event
Notification Rule Owner=SYSMAN
Notification Count=1
The clients applications are having similar errors when trying to connect. This seems to be happening after replication has been running for a while (1 -2 weeks) on the SQL server 2005 side...
We are using Snapshot Replication for the 10g database (every 20 minutes)
and transactional replication on the 9i database...
We are replicating 28 tables from the 10g database (500Mb Via Snapshot Replication)
And 171 Tables for the 9i databases (Near 3Gb Via Transactional Replication)
Thanks for the help !

Here is an error from the 9i database Client: (this seems to be correct %s values)
ORA-04031: Unable to allocate 20236 bytes of shared memory("shared pool", "unknown object", "sga heap(1,0)", "session param values");

SORT_AREA_SIZE+Oracle dedicated servers

Hi Friends,
I am using Oracle 10g server release 2,Today i have gone through the Orcale docs,its written there that
"Oracle does not recommend using the SORT_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. SORT_AREA_SIZE is retained for backward compatibility"
My database is designed in dedicated mode..now how to handle large sorts in that case,as oracle recommends something different
thanx
somy

Oracle document covers nicely the [PGA Memory Management|http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/memory.htm#PFGRF01401]
Check out [V$PGA_TARGET_ADVICE|http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/memory.htm#i49570] for getting an idea about the ideal size of your PGA.
Thanks,
Karthick.

When I try to connect using user, Its not throwing any error but not connecting. Just the cursor is blinking...
How to fix this issue.
Thanks in advance
-Mani

Hi,
I didnt see any error message in alert log. Its not logging any message while connecting DB using SYSDBA.
My DB is in NOARCHIVELOG mode.
Sill non DBA users are not able to login.
