How to refresh the Oracle Cache?

Hi,
I am dealing with millions of records. Every time, the cache is full. It causes my system to be slow. Could any one tell, how to refresh the cache.
Thanks and regards
Gowtham Sen.

Hi Eric,
I think that, it may cause the system to be slow. Actually my system (LINUX server Enterprise 3 ) has 1GB RAM.
There I am running DB 10g , Work flow server 2.6.3, OWB 10G, Oracle Middle ware (HTTP server, portals).
I don't know, why the systen is too slow?
Could you please give some suggestions to increase the performace.
Thanks and regards
Gowtham Sen.

10G NEW FEATURE-HOW TO FLUSH THE BUFFER CACHE

10G NEW FEATURE-HOW TO FLUSH THE BUFFER CACHE
===============================================
PURPOSE
이 자료는 Oracle 10g new feature 로 manual 하게
buffer cache 를 flush 할 수 있는 기능에 대하여 알아보도록 한다.
Explanation
Oracle 10g 에서 new feature 로 소개된 내용으로 SGA 내 buffer cache 의
모든 data 를 command 수행으로 clear 할 수 있다.
이 작업을 위해서는 "alter system" privileges 가 있어야 한다.
Buffer cache flush 를 위한 command 는 다음과 같다.
주의) 이 작업은 database performance 에 영향을 줄 수 있으므로 주의하여 사용하여야 한다.
SQL > alter system flush buffer_cache;
Example
x$bh 를 query 하여 buffer cache 내 존재하는 정보를 확인한다.
x$bh view 는 buffer cache headers 정보를 확인할 수 있는 view 이다.
우선 test 로 table 을 생성하고 insert 를 수행하고
x$bh 에서 barfil column(Relative file number of block) 과 file# 를 조회한다.
1) Test table 생성
SQL> Create table Test_buffer (a number)
2 tablespace USERS;
Table created.
2) Test table 에 insert
SQL> begin
2 for i in 1..1000
3 loop
4 insert into test_buffer values (i);
5 end loop;
6 commit;
7 end;
8 /
PL/SQL procedure successfully completed.
3) Object_id 확인
SQL> select OBJECT_id from dba_objects
2 where object_name='TEST_BUFFER';
OBJECT_ID
42817
4) x$bh 에서 buffer cache 내에 올라와 있는 DBARFIL(file number of block) 를 조회한다.
SQL> select ts#,file#,dbarfil,dbablk,class,state,mode_held,obj
2 from x$bh where obj= 42817;
TS# FILE# DBARFIL DBABLK CLASS STATE MODE_HELD J
9 23 23 1297 8 1 0 7
9 23 23 1298 9 1 0 7
9 23 23 1299 4 1 0 7
9 23 23 1300 1 1 0 7
9 23 23 1301 1 1 0 7
9 23 23 1302 1 1 0 7
9 23 23 1303 1 1 0 7
9 23 23 1304 1 1 0 7
8 rows selected.
5) 다음과 같이 buffer cache 를 flush 하고 위 query 를 재수행한다.
SQL > alter system flush buffer_cache ;
SQL> select ts#,file#,dbarfil,dbablk,class,state,mode_held,obj
2 from x$bh where obj= 42817;
6) x$bh 에서 state column 이 0 인지 확인한다.
0 은 free buffer 를 의미한다. flush 이후에 state 가 0 인지 확인함으로써
flushing 이 command 를 통해 manual 하게 수행되었음을 확인할 수 있다.

How to upgrade the Oracle Client silently ?

Hi all,
I have to upgrade the Oracle Client from 8.1.6.0.0 to 9.2.0.1.0.
I use the -record option for creating the destination file or edit the response file manually for being able to install the new client. But I have no idea, how to remove the old client.
The following command doesn't work:
C:\Program Files\Oracle\oui\install\setup.exe" -deinstall DEINSTALL_LIST={"oracle.client","8.1.6.0.0"}
What am I doing wrong? How to remove the Oracle Client silently?
Thanks for the help and best wishes from Frankfurt.
Dimitri

I created a instant client silent DE-INSTALL for version 10.1.0.2 on XP.
setup.exe -silent -deinstall -responseFile Z:\yyyyyy\xxxxxx.rsp
These are parameters are in my response file...
ORACLE_HOME="C:\oracle\InstantClient\10.1.0"
ORACLE_HOME_NAME="OraInstantClient10g_home1"
TOPLEVEL_COMPONENT={"oracle.client","10.1.0.2.0"}
DEINSTALL_LIST={"oracle.client","10.1.0.2.0"}
SHOW_SPLASH_SCREEN=false

SHOW_EXIT_CONFIRMATION=false
SHOW_DEINSTALL_CONFIRMATION=false
SHOW_DEINSTALL_PROGRESS=true
REMOVE_HOMES={"c:\oracle\ora81","c:\oracle\InstantClient\10.1.0"}
You still have to manually update/remove the PATH & TNS_ADMIN environment variables and the file system directories.

How to install the oracle lite mobile server?

hi,every one!
I follow the wizard of the oracle lite mobile server,then
pop the window let me input the "host name""port"and "net server name",I have install oracle 9i,and establish a database named "oradb",establish an server named"oradb",the service can be listened and the port is "1521",but in the installation when i input the up numbers, it
tells me that "invalid server name",how can i do?
somebody that do me a favor tell me how to install the oracle 9i lite mobile server,it must be preciated!

Andy,
It sounds like you are not properly connecting to the back end Oracle instance when Lite attempts to install the Mobile Server Repository.
Before attempting a re-install, why don't you try connecting to the same instance using SQL/Plus with the a connect string specifying hostname:1521:SID. If you are not able to connect you need to determine why.
TNX,
Phil

How to install the Oracle Enterprise Manager Database Tuning ?

Hi,
How to install the Oracle Enterprise Manager Database Tuning with the Oracle Tuning Pack
Release 9.0.1
And where to get download this.
Thank u..!

The only way you can get 9iR1 release software is by asking it to your Oracle representative. The oldest 9i release available for public download is 9iR2.
You could try the administrative 9iR2 client, it can work with 9iR1 releases.

How to deploy the Oracle Forms and Reports 10g in Web?

Currently I am working in Oracle forms & Reports conversion project (6i to 10g).
As of now 6i forms working as a standalone application. After migrated it to 10g, I need to deploy the forms and reports in web.
Any one know how to deploy the Oracle forms and Reports in web?
Please help me out. Thanks in advance.
Vimal

Hello Frank,
for development, you need to install Oracle Developer
Suite 10g. This includes Forms and Reports.this topic interests me too, because I've downloaded Developer Suite and Database (both for 10g) from Oracle website, installed them, but I couldn't connect to a database.
What should be done for me to create a database link and be able to connect locally, in my personal Desktop computer? (Not to a server)
Once it was told me here that I should download 10g Database - I did it, and installed it, but it didn't work. Later, some of my job partners said I should install them in a sequence - that is, 1st the Developer, and 2nd the Database. But it has failed too. And I don't know how to configure a database connection.
Best regards,

How to Enable the Oracle BPM Worklist?

Hi!
Newbie here.
So how do you enable the Oracle BPM Worklist?
Sure there a tutorial for this found in http://docs.oracle.com/cd/E21764_01/doc.1111/e17366/chapter16.htm#BABHCICI
and in section "16.2 How to Enable the Oracle BPM Worklist" it says
"By default, Oracle BPM Worklist functionality is disabled. You can enable this functionality in AIAConfigurationProperties.xml.
To enable the Oracle BPM Worklist:
-Access AIAConfigurationProperties.xml located in <AIA_HOME>/aia_instances/$INSTANCE_NAME/AIAMetaData/config.
-Set the EH.INVOKE.HWF property value to true.
-Reload updates to the AIAConfigurationProperties.xml file."
However upon searching for the file "AIAConfigurationProperties.xml" or even the directory "aia_instances" in our servers, I could not find them. Please help me!

If you are talking about 11g Worklist app, then you won't be able to do that, since the source code is not shipped with the product. The better way is to create the custom worklist application using the Worklist APIs. Refer to the SOA Developers Guide.
In case of 10g, you can access the source code of Worklist app, even in that case, you can do your requirement using the exposed APIs.

How to refresh the ALV Tree

Hi,
I have an ALV Tree report developed using the OOPS. In my ALV Tree output, I have some buttons which will update the database after clicking. The data is correctly updating in the database. But, it is not getting updated in the ALV Tree display. That means, it is not REFRESHing the ALV Tree display. We have to again execute the program in order to see the updated output.
Could anyone please suggest me how to Refresh the ALV Tree display..?
We can't use the method 'REFRESH_TABLE_DISPLAY' as it is a PRIVATE method is the class CL_GUI_ALV_TREE.
Please share your valuable thoughts.
Thanks & Regards,
Paddu.

How to refresh the panel's display in listener?

I have a Jcombobox and a panel(square,background color:white). I want user to choose the panel's size from the combobox and thus change the panel's display. However, when I choose a value from combobox, the panel's size DOES change, but the display cannot be rerfreshed realtimely. It still display the panel by previous size. If I minimize the whole window and restore, then the panel gets refreshed, displaying by new size.
Can anybody tell me how to refresh the panel's display dynamically? thank you a lot.
sraiper

if we bounce the listener the connections to other might be lost.NO!
The listener contacts the DB to establish the initial connection between client & DB.
After the connection between DB & client has started, the listener has NO involvement between DB & client.
Stopping the listener has NO impact on existing sessions.

You did not mention exactly which Forms version you are using so it will be difficult to offer specific help. However, you did mention Forms 9i. ALL "9i" releases were desupported long ago, so find software or documentation are becoming more difficult.
Here is the Deployment Guide for Forms 10.1.2

How to refresh the table control on some action

Hi All,
     In a web Dynpro application, I am filling data to the Table control through Supply function. When I do some action (like save new record ) i want to refresh the table control means add the newly added record.
   How to refresh the Table control.
Thanks
Hemalatha

hi hema........
    if you are using a select query inside the supply function...
    then...
    you can just use node->invalidate(). method..
    it just invalidates the node that is bound to the table.
   so the supply function will be called again, which again uses the select query to fetch the values.. so that your table gets refreshed.
