Data retrieval buffers - buffer size and sort buffer size

Any difference to tune BSO and ASO on data retrieval buffers?
From Oracle documentation, the buffer size setting is per database per Essbase user i.e. more physical memory will be used if there are lots of concurrent data access from users.
However even for 100 concurrent users, default buffer size of 10KB (BSO) or 20KB (ASO) seems very small compare to other cache setting (total buffer cache is 100*20 = 2MB). Should we increase the value to 1000KB to improve the data retrieval performance by users? The improvement impact is the same for online application e.g. Hyperion Planning and reporting application e.g. Financial Reporting?
Assume 3 Essbase plan types with 100 concurrent access:
PLAN1 - 1000KB * 100 = 100MB 1000KB * 100 = 100MB (total sort buffer size)
PLAN2 - 1000KB * 100 = 100MB 1000KB * 100 = 100MB (total sort buffer size)
PLAN3 - 1000KB * 100 = 100MB 1000KB * 100 = 100MB (total sort buffer size)
Total physical memory required is 600MB.
Thanks in advance!

256 samples Buffer size will always give you a noticable amount of latency. If you use Software Monitoring you should try setting your Buffer to 64 samples. With the recording delay slider in the preferences->Audio you can compensate for the latency (of course not in realtime) so that the Audio will be placed exactly there, where it should hae been recorded at. In your case set it to a -value. A loopback test (check the link below) will clarify the exact amount of Latency occuring on your system.

Query about Keep Buffer Pool and Recycle Buffer Pool

What will Keep Buffer Pool and Recycle Buffer Pool contains actually in Database Buffer Cache, specially what type of objects? I know the definitions but need to know the practical aspects about them.

Just to echo the same, in any cache, either Buffer Cache(default), Keep or Recycle, its going to be data buffers which are actually the placeholders for the data blocks that are available on the disk. The default cache is going to throw away the lesser used buffers as fast as possible. And if you don't want this to happen, you can use either of the other two, indepandant caches-Recycle and Keep. The keep cache , as the name suggests would keep the buffers in it for a more loonger duration compared to the default cache. This probably would be a better idea when you know that some buffers are meant to be reused again and again. Recycle is going tobe for those, which are very seldom used and you don't want them to choke up the caches at all. For the buffers kept in the Recycle cache, they would be thrown out almost instantly.
Read the link that's given to you. It contains a lot of stuff that would further make things clear.

Pga and sort area size both are set in parameter file

Hello,
Both the pga and sort area size are set in the parameter file. Is this an issue? Are there conflicts? Can both be set and only pga will take effect? Db is 10.1.0.5.

Rounding Value,Minimum Lot Size and Maximum Lot Siz parameters

Hello Gurus,
Please explain me the what is the use of the parameter Rounding Value
,Minimum Lot Size and Maximum Lot Size parameters in the product master and how does it in impact during the Heuristic Run?
Thanks.

Rounding value is the incremental quantities in which the order can be produced/procured. Eg. if orders are possible with quantities 40,60, 80, 100 etc..then rounding value is 20.
Min lot size is the minimum quanity in which order can be produced eg. 40 in above example
Max lot size is the maximum quanitity in which the order can be produced/procured. eg. 100 in our example
Impact on Heuristic run: heuristics takes all the above parameter to plan supply order. eg. if requirement is 55, it will supply plan for 60. If requirement is 120, it will produce two orders - one for 100 and the other for 20. if the reuqirement is 10, the order size will be 40.
Hope this helps.

Retrieval and Sort Buffer settings w/ASO in 9.2.02

Are there differences in the limits on setting the retrieval and sort buffers between BSO and ASO or System 9 and prior versions? Traditionally, the limit was 100 to maintain a stable environment.

Urgent: Huge diff in total redo log size and archive log size

Dear DBAs
I have a concern regarding size of redo log and archive log generated.
Is the equation below is correct?
total size of redo generated by all sessions = total size of archive log files generated
I am experiencing a situation where when I look at the total size of redo generated by all the sessions and the size of archive logs generated, there is huge difference.
My total all session redo log size is 780MB where my archive log directory size has consumed 23GB.
Before i start measuring i cleared up archive directory and started to monitor from a specific time.
Environment: Oracle 9i Release 2
How I tracked the sizing information is below
logon as SYS user and run the following statements
DROP TABLE REDOSTAT CASCADE CONSTRAINTS;
CREATE TABLE REDOSTAT
AUDSID NUMBER,
SID NUMBER,
SERIAL# NUMBER,
SESSION_ID CHAR(27 BYTE),
STATUS VARCHAR2(8 BYTE),
DB_USERNAME VARCHAR2(30 BYTE),
SCHEMANAME VARCHAR2(30 BYTE),
OSUSER VARCHAR2(30 BYTE),
PROCESS VARCHAR2(12 BYTE),
MACHINE VARCHAR2(64 BYTE),
TERMINAL VARCHAR2(16 BYTE),
PROGRAM VARCHAR2(64 BYTE),
DBCONN_TYPE VARCHAR2(10 BYTE),
LOGON_TIME DATE,
LOGOUT_TIME DATE,
REDO_SIZE NUMBER
TABLESPACE SYSTEM
NOLOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
MONITORING;
GRANT SELECT ON REDOSTAT TO PUBLIC;
CREATE OR REPLACE TRIGGER TR_SESS_LOGOFF
BEFORE LOGOFF
ON DATABASE
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
INSERT INTO SYS.REDOSTAT
(AUDSID, SID, SERIAL#, SESSION_ID, STATUS, DB_USERNAME, SCHEMANAME, OSUSER, PROCESS, MACHINE, TERMINAL, PROGRAM, DBCONN_TYPE, LOGON_TIME, LOGOUT_TIME, REDO_SIZE)
SELECT A.AUDSID, A.SID, A.SERIAL#, SYS_CONTEXT ('USERENV', 'SESSIONID'), A.STATUS, USERNAME DB_USERNAME, SCHEMANAME, OSUSER, PROCESS, MACHINE, TERMINAL, PROGRAM, TYPE DBCONN_TYPE,
LOGON_TIME, SYSDATE LOGOUT_TIME, B.VALUE REDO_SIZE
FROM V$SESSION A, V$MYSTAT B, V$STATNAME C
WHERE
A.SID = B.SID
AND
B.STATISTIC# = C.STATISTIC#
AND
C.NAME = 'redo size'
AND
A.AUDSID = sys_context ('USERENV', 'SESSIONID');
COMMIT;
END TR_SESS_LOGOFF;
Now, total sum of REDO_SIZE (B.VALUE) this is far less than archive log size. This at time when no other user is logged in except myself.
Is there anything wrong with query for collecting redo information or there are some hidden process which doesnt provide redo information on session basis.
I have seen the similar implementation as above at many sites.
Kindly provide a mechanism where I can trace which user is generated how much redo (or archive log) on a session basis. I want to track which all user/process are causing high redo to generate.
If I didnt find a solution I would raise a SR with Oracle.
Thanks
[V]

You can query v$sess_io, column block_changes to find out which session generating how much redo.
The following query gives you the session redo statistics:
select a.sid,b.name,sum(a.value) from v$sesstat a,v$statname b
where a.statistic# = b.statistic#
and b.name like '%redo%'
and a.value > 0
group by a.sid,b.name
If you want, you can only look for redo size for all the current sessions.

Fixed lot size and Minimum lot size

Dear senior,
My client has the following scenario. His supplier provides the item in a fixed lot size of 100. The minimum lot size to be ordered is 300.
The supplier is a fixed vendor.
I tried to maintain this information in the Material Master MRP views. Lot size - FX, Fixed lot size - 100, Minimum lot size - 300.
However, everytime, the minimum lot size will get reset.
Is there any way , I can maintain this scenario via configuration or any other method?
Thank you.

Hi,
Fixed lot size - 100 means for every 100 quantity system will create one purchase document.
If you selected Lot size - FX - Fixed order quantity , then no need to maintain Minimum lot size & Maximum lot size fields.
Then you have to maintain Fixed lot size filed only.
Ex:
Lot size = FX
Fixed lot size = 100
There is a requirement of 300. Then system will create 3 PO's with quantity of 100 each.
If Lot size is Ex - Lot-for-lot order quantity, then only need to maintain Minimum lot size & Maximum lot size fields in the MRP 1 view.
Ex: Lot size = EX
Minimum lot size = 60
Maximum lot size = 100
There is a requirement of 250. Then system will create 3 purchase documents, two documents with the quantity of 100 and third one with the quantity of 60.
That's why, in your case system is reseting Minimum lot size every time.
If you want to maintain Minimum lot size, then maintain
Lot size as EX
Minimum lot size = 100
Max lot size = 300
It will solve your problem.

Based on my computer what I/O buffer size and process buffer should I have to stop getting the system too slow error message?

I need some sugestions on my settings. I have a 13 in macbook pro runnig 10.8.2 with a 2.7 Ghz i7 with 4 GB of ram.
I am using Logic pro X 10.0.3 and when I get to a really load heavy section of a project then I get a too slow error message.
I know this will happen from time to time because of my computer but is there anyway to make it better?

Im curious how you are running LPX on an OS X 10.8.2 system?
As to your question.. there is no specific answer... Try playing with the settings (making a note of your current ones) and see what improvements, if any, are made under different combinations of the settings.
Personally I'd add more RAM if you can... as that alone may help matters by some degree...
Finally,
This article may also help.. (Its written for LP9 but most of it is applicable for LPX too)

Setting icon size and sorting in 10.9

I asked this question in the os X forum. Maybe I can get an answer here.
The following worked in 10.8 but not in 10.9:
tell its icon view options
set icon size to 128
set shows icon preview to true
set arrangement to arranged by name
end tell
icon size is not set and the icons are not rarranged.
Apparently icon size is now read only. There must be a way to resize the icons.
Any ideas?

For example:
tell application "Finder"
    activate
    try
        set theName to name of Finder window 1
    on error
        return beep 1 -- no open Finder window
    end try
end tell
tell application "System Events" to tell process "Finder"
    tell menu 1 of menu bar item "View" of menu bar 1
        if exists menu item "Show View Options" then keystroke "j" using {command down}
    end tell
    repeat until exists (window 1 whose (title is theName) and (subrole is "AXSystemFloatingWindow"))
    end repeat
    tell window 1
        set value of slider 1 of group 1 to 56.0 -- 128 x 128
        tell checkbox "Show icon preview" of group 1
            if value is 0 then click
        end tell
        click pop up button 1
        keystroke "Name" & return -- arrange by name
        click button 1 -- close
    end tell
end tell
You should also have a look at Accessibility Preferences and GUI Scripting.

How can I switch off the automatic window size and set the size of the window manually

I need to open the web-page in a window of a certain size. The javascript function window.resizeTo (w, h) does not work. If I open the window using the window.open ("", "", "width: w, height: h, ..."), there is another problem.
The hyperlinks that have to be opened in a new tab in the same window or at least in the window of the same size, will open in another tab of the first window from which I called window.open().
I do not know what it is, bug or as intended, but the normal full-featured window with the right size I cannot get.
In Russian:
Мне нужно открыть страницу в окне определенных размеров.
Из консоли Firebug с помощью javascript пробовал window.resizeTo(w,h) - не работает. Если открывать окно с помощью window.open("", "", "width:w, height:h, ..."), то возникает другая проблема: ссылки, которые должны окрываться в новой вкладке в том же окне или хотя бы в окне того же размера, открываются в другой вкладке первого окна, из которого я выполнял команду window.open(), которое неправильного размера.
Не знаю, что это. Баг или так задумано. Но открыть нормальное полноценное окно с нужными размерами не получается никак.

You need an extension if you want to set the window dimensions to a specific value or you need to open a pop-up window with window.open and specify the width and height.<br />
Otherwise a new window opens with some default dimensions as saved in localstore.rdf and you can't easily adjust the dimensions via JavaScript in that case.

Document size and final print size

I am beginning a new aerial drawing in Illustrator CS4 on an 2009 imac, to be printed at 40x40". If the document is sized at 40x40, the computer slows down as detail accumulates. Since Illustrator is a vector-based application, can the document size be set smaller than the final print size, say at 20x20" or 10x10", to keep file size down and speed faster, without losing print quality?
Thanks for any help!

function(){return A.apply(null,[this].concat($A(arguments)))}
without losing print quality?
Depends on the specific content of the file and what exactly you mean by 'setting the document size smaller.'
Better would be to try to discern what is causing the performance issue. Again, that comes down to what the content is.
