Setting Oracle Parameters

Hi Gurus,
I have a question in setting a oracle parameters in newly created database(Like DB_block_buffers and pools and etc.,).
How i can determine these characterstics, i mean on what basis we will determine ?
Anybody have white papers regd this ?
I appreciate anyform of help.
Thanks in advance.

James, the detail you asked for is contained in those two posts namely the reference to the Performance and Tuning manual section on buffer pool sizing.
The fact of the matter is that the size of the pool is dependend on the concurrent user load and the size of the average transaction that the application is going to perform.
You have provided no useful information on the type of database, concurrent user load, type and nature of application, average transaction size, size of the database, version of Oracle to be used, hardware capacity, etc... Even if you did because of the wide range in application behavior any answer you get will be guess work.
Pick a size based on your best guess and monitor. Normally you build a test system before you build a production system and you can use the test system as a basis for selecting the production parameters.

Hi
Please try this link.
http://oracle.basisconsultant.com/oracle_tuning_parameters.htm
http://www.orafaq.com/wiki/Oracle_database_Performance_Tuning_FAQ
But before doing this, check for all the probabilities as it requires lots of data and traces to do the parameter tuning.

Problem with setting oracle type parameter in viewobject query

Hi There,
I am facing a problem with JDev1013. I have a view that has JDBC positional parameters that are supposed to be in parameters for function like:
SELECT x.day, x.special_exact_period_only
FROM (
SELECT x.day, x.special_exact_period_only
FROM (
    SELECT
      x.day,
      rb.special_exact_period_only
FROM TABLE (
    RentabilityPkg.findMarkerSlots(
      'start',
      ? /* dchannel */,
      NULL,
      ? /* resorts */,
      'special',
      NULL,
      ? /* code */,
      NULL,
      TRUNC(SYSDATE),
      TRUNC(SYSDATE + 365 * 2),
      NULL
) x
    JOIN resourcebase rb USING (rentabilitymanager_id)
    UNION
    SELECT
      x.day,
      rb.special_exact_period_only
    FROM TABLE (
      RentabilityPkg.findMarkerSlots(
        'start',

Problem in setting the parameters for an OASingleSelectionBean

Hi,
I have created an advanced table, for which I have to allow single selection or mutliple selection according to my requirements ie dynamically. So, for single selection, I have created a OASingleSelectionBean dynamically and add this to my advanced table bean.
I also want to set Action for the single selection option. I have set the action using
setPrimaryClientAction() which takes an argument of oracle.cabo.ui.action.FirePartialAction class. Now I also want to pass certain parameters when the single selection event happens.
For that, I have taken an object of FirePartialAction class and but using the FirePartialAction class .setParameters(oracle.cabo.ui.collection.Parameter[]) function. I am setting the parameters using
Parameter class object.setKey
Parameter class object.setValue
But my problem is that I want the value for the parameters at runtime, for which I intend to use SPEL. But I am not able to use SPEL using the setValue method.
So it goes like this in short:
OAAdvancedTableBean.setTableSelection(OASingleSelectionBean)
OASingleSelectionBean.setPrimaryClientAction(FirePartialAction)
FirePartialAction.setParameters(Parameter[])
Parameters.setKey(String)
Parameters.setValue(String) --- In case of value I want to give SPEL as an argument as I get the value at rutime
Is that any other way in which I can set the value for the parameters using SPEL?

Hi,
I got ur point.
Although i have never tried.........Can you try using method
Parameters.setValueBinding(new OADataBoundValueViewObject(<single selectionbean>,<vo attr>))
In this way without the use of SPEL, you will be able to achieve the functionality!
Try this and get back to me!

Oracle parameters related kernel parameters

Hi,
Can anyone tell me hwo can i get the info about the oracle parameters which are related to os, for example- i am getting a request to change the process parameter for the db instance which are the kernel parameters need to be changed..
so we have to relate the kernel parameters with database parameters. like this, can i get anywhere for oracle parameters which are associated with kernel parameters. Please let me know if anyone has this information.
Thank u.

990991 wrote:
Hey.. i want to know which oracle parameter is associated with kernel parameters ..
something like this shmmax === related SGA (which exact oracle parameter of SGA need to be changed at database level) similarly for process parameter which parameter is related at os level (in kernel parameters)
I think my question is clear now.. to get the appropriate help.
Thank U..
Did you consider that it is not a one-for-one relationship?
The installation guide is very explicit about how to set the kernel parameters.
Most importantly, what error triggered this request? We often see people chasing the wrong solution for their unstated problems.

Hi -K-
actually I want to make SqlDeveloper to make case insensitive search.
when I google, I've found to make oracle as case insensitive I need to set NLS_SORT to Binary_CI and NLS_COMP to LINGUISTIC
Default SQLDEVELOPER NLSParmeters values are as NLS_SORT---->Binary and NLS_COMP--->Binary
Now I want to make these as NLS_SORT---->Binary_CI and NLS_COMP--->LINGUISTICS.
thanks,
harry

Set archiving parameters on physical standby

most respected forum members,
i have two databases both are oracle 9i release 2 on windows server 2003.
A (this is production database)
B (i want to make this standby )
on A (production machine ) i set parameters
alter system set log_archive_dest_1 = 'location =E:\oracle\archives'
alter system set log_archive_dest_2 = 'service (tnsnames entry from standby db)
standby_archive_dest = 'E:\oracle\archives'' (the location is same on standby as it on primary)
on B (standby db) how i set these parameters.
plz reply in detail
regards
Edited by: user10204771 on Apr 17, 2009 6:57 AM

hi werner,
the link u told me , i m following the same doccument.
here it is chapter 3 creating physical standby db.
while enable archiving on standby db , here the parameters are
alter system set log_archive_dest_2 = 'service = (here the tnsnames entry will be from tns of primary db or standby) bcz in primary tnsnames entry is "REPEIMS" and in standby the tnsnames entry "REPSTDY".
Moreover when i will change my standby db to archivelog mode where i will set that destination
alter system set log_archive_dest_1 = 'Location (here like this) or some other parameter'

Hi Dashan,
it depends or in other words what is management server for you? There's a change from 9i to 10g. In 10g we have dbconsole dedicated to one specific database or gridcontrol as centralized monitoring utility for many databases, application servers and so on. If it is standalone console command is 'emctl start dbconsole', this command starts the console itself and the integrated agent. For gridcontrol use 'opmnctl startall' to start all necessary services, these are many as 'opmnctl status' shows.

Y setting kernel parameters in linux and not in windows

Hi Can any one please help me out...
While installing oracle on linux we are setting some kernel parameters But when installing in windows are we setting any kernel parameters...We are not setting any parameters...can any one please explain why r we setting kernel parameters and what is the use of those parameters and why are we not setting any parameters in windows.

probably because linux != windows
anyway, there are still some recommendation you can follow, for example if you want to use more than 2Gb of memory in win32

Unable to set kernel parameters using solaris 10

HI,
I'm trying to install DB2 8.2 on solaris 10.the problem i'm encountering in installation is unable to set MSGMAX and MSGMNB kernel parameters. I tried setting the new replacement parameter process.max-msq-qbytes through projects->Resource Control from the management console.but still uinable to set the parameters.
Can anyone help me in setting the above kernel parameters.
Its not possible to set it thru /etc/system.
thanx

I finally had some time to find the actual syntax for tuning process.max-msq-qbytes and process.max-msg-messages. prctl will change those paramaters for an existing process.
As a proof of concept I changed process.max-msg-messages to a 64k. process 2221 is my shell.
prctl -n process.max-msg-messages -r -v 64k 2221
bash-3.00# prctl 2221
process: 2221: -csh
NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
process.max-port-events
        privileged      65.5K       -   deny                                 -
        system          2.15G     max   deny                                 -
process.max-msg-messages
        privileged      64.0K       -   deny                                 -
        system          4.29G     max   deny                                 -
process.max-msg-qbytes
        privileged      64.0KB      -   deny                                 -
        system          4.00GB    max   deny                                 -And now to make this persist across reboots...
So long as I'm experimenting, I'll use projadd and add a new project which just includes me and not the rest of the users in the group staff.
bash-3.00# projadd -p 115 -U testuser \
-K "process.max-msg-messages=(priv,64K,deny)" \
-K "process.max-msg-qbytes=(priv,64K,deny)" \
user.me This creates the following /etc/project:
(note the last line is all on one line in the real file minus the \.)
placer% cat /etc/project
system:0::::
user.root:1::::
noproject:2::::
default:3::::
group.staff:10::::
user.me:115::testme::\
process.max-msg-messages=(priv,64000,deny);process.max-msg-qbytes=(priv,65536,deny)After a reboot I checked the values by loging in under my user and running prctl.
placer% prctl $$

...Solaris 10 has different tunables and default values from 8 and 9. It's default tunables should be good for most applications per a given system's hardware. There are some great blog articles, and discussions on opensolaris.org and blogs.sun.com on tuning that explain the intent of tuning and why we shouldn't have to tune.

Using SET GET parameters in ITS

Hi All,
Is it possible to use set get parameters in ITS. We want to set some parameters in a BADI and read the value in ITS Template .
Or is there any other method to do this?
Thanks,
Anubhav

Sure. In your abap program use the following code
* ITS macros
INCLUDE avwrtcxm.
GET PARAMETER ID 'YOUR_PARAMETER' FIELD SAVE_PARAMETER.
field-set u2018~YOUR_PARAMETERu2019 1 SAVE_PARAMETER.
field-transport.
in the template you can now use ~YOUR_PARAMETER.
regards,
Klaus

Problem with SET GET parameters

Hi all,
I am facing a problem using SET and GET parameters.
There is a Z transaction(Dialog program) where some fields of screen are having parameter ID's. That transaction is designed to diaplay/change status of only one inspection lot at a time.
Now I need to call that transaction in a loop using BDC. I mean i need to update the status of multiple inspection lots(one after the other). Before calling the transaction I am using
SET PARAMETER ID 'QLS' FIELD lv_prueflos.
Unfortunately the transaction is only changing the first inspection lot. When I debugged I found that the screen field is changing in PAI. Even though in PBO it shows the next value, when it goes to PAI it is automatically changing to the first value(inspection lot).
Example: Inspection Lots : 4100000234
4100000235
4100000236
Now first time when the call transaction is being made the status of insp lot 4100000234 is changed. For the second time when insp lot 4100000235 is being passed in PBO ican see this. But the moment it enters PAI the screen field changes to 4100000234.
Could you pls help me in solving this issue.
Thanks,
Aravind

How to use SET & GET Parameters in Module Pool

Hi Friends,
Can anyone please tell how to use SET / GET parameters and PARAMETER ID for a text box (Input / Output field ) in module pool? What is the purpose and where do we need to do coding for it?
Note : I will definitely give the marks for good responses.
Thanks in advance,
Pradeep

Hi Pradeep,
You can save values in the SAP memory using a parameter ID. These
are user and terminal-session specific, but available to all internal and
external sessions.
SET Parameter copies the corresponding field contents into the SAP
System memory in the PAI processing block.
GET Parameter copies the corresponding field contents from the SAP
memory at the end of the PBO processing block, after data has been
transferred from the program, if the screen field still has its initial value
You can link an input/output field to an area of the SAP memory in the
ABAP Dictionary.
When you use an input/output field that is defined in the ABAP
Dictionary, its parameter ID is displayed in the Dictionary attribute
Parameter ID in the Screen Painter.
Usage
SET PARAMETER ID: CAR FIELD space,
CON FIELD space,
DAY FIELD space.
Here is the link that explains the usage of GET/SET in detail
