We are using one software it is a test tool for verify the data base posting speed from server to client systems. In windows 2008 R2, database posting speed is very slow when compare to windows 2003 server .
Server configuration is same for both servers ( RAID 5 , RAM 4 GB) how we can improve writing performance in Oracle
I have two same DB schema (same structure, same data) and I need to provide update in one of them when data in the other one is updated. It is singe direction only (we change data in DB Schema A and synchronize data in the DB Schema B; there is not opposite direction). Only small portion of data (compared to the size of DB Schema) might be changed or added this way.
View 1 Replies View RelatedI have an Oracle Form 6i. There are two blocks. One is a database block called CUSTOMER and the other is a non-database block called CONTROL.
In the PRE-INSERT trigger of the database block, values from the non-database table block are passed to the database table block. When I pass values I use the :BLOCK_NAME.field_name eg. :CUSTOMER.scale_code := :CONTROL.scale.
In this form the values passed to the database block from the non-database block in the PRE-INSERT trigger do not use the block name e.g. :-
:warehouse := :global.default_warehouse;
:capturer :=captured
:scale_code := scale;
:date_captured := sysdate;
insert into dd_audit(cus_id,cap_date) values(:CONTROL.cus_id,SYSDATE);
This application used to work fine for months, last week when writing the values in the PRE-INSERT trigger, just the warehouse field had a value. The remaining fields after the warehouse did not pass any values, although it was verified that values would have been present in the non-database block. The date_captured field should have at least had the system date. The last insert into dd_audit was successful.
I have done numerous tests on our test database and could not replicate the problem. Would passing the values from the non-database block to the database block without the :BLOCK_name preceding the field name cause this problem.

Error: PLS-00306: wrong number or types of arguments in call to 'PUT_LINE'
I have the following tables & data ..
create table identity (IDENTITY_ID varchar2(100));
Insert into identity values ('100');
Insert into identity values ('101');
create table CM_ENCOUNTER (IDENTITY_ID varchar2(100), CSN varchar2(100));
Insert into CM_ENCOUNTER values ('100','3a1');
Insert into CM_ENCOUNTER values ('101','1a2');

Insert into CM_ENCOUNTER_RFV values ('100','23vx','2', 'phone');
commmit;
The output needed is :
<EvaluatePatient>
<PatientInformation>
<Patient>
<mrn>100</mrn>
<CSN>3a1</CSN>
[code]......
Based on the above, I created a table (which is of xml) ...
Create table temp_xml
as
Select XMLELEMENT("PatientInformation",(XMLELEMENT("Patient",
XMLELEMENT("mrn", s.identity_id),
XMLELEMENT("CSN", m.csn),
XMLELEMENT("Gender", p.gender),
[code]........
Now, I need to write each record into xml file. So, I used the below to write into file..but it gives me an error...wrong number of arguments to utl_file at line 14.
DECLARE
CURSOR c_data IS
SELECT * from temp_xml;

The query should be in this fromat

we are using oracle 9i on AIX Server. When Customer were accessing the database, accidentally power was shut down. we restarted the Server,and Oracle database. all resumed successfully.
However while doing "Payments by the customer" it takes a lot of time to insert even a single payment record on database.The database is Live and our customer are very much frustrated,
I have a RAC 48 cores on solaris. I check dbconsole when application performance is very slow and everyone complains, and I see that the main wait is cpu - also on the awr report. however when I check server cpu I see about 80% idle! so how can I make oracle use more cpu power instead of waiting for it? I don't think that parallel is an option here because I can't change the application code.

I am migrating a oracle 9i database to 11g r3. I can only use imp. As the database is huge, I have split the exp dump by schemas. In my recent test, i have split the schema into 4 seperate threads to be imported into the new oracle11g database. The 4 thread of imp consist of almost similar sizes of schema (Eg thread 1 - Schema 1, 2 ,3. Thread 2 - Schema 4,5,6 etc)
All the dump files are in the same mount point. When i execute the import (4 threads) together, the total import timing is each thread is between 2.5 days to 3.5 days.
Then i proceed to try only 1 thread, only 2 hrs. So could this be a IO issue or oracle memory problem?

We have a function that is called in various other PL/SQL packages, and performance has always been very good. On 29th Sept we upgraded our db to 10.2.0.5.0 and since then, a package that calls the function has gone from ~4mins, to ~2.5hrs to run.
In PL/SQL Developer, a simple select that calls the function has gone from ~0.5secs to retrieve the first 100 rows, to ~12secs. I ran a profile of the main package, which highlighted the where the bottleneck was (a fetch from an explicit cursor). Running an explain plan on the cursor SQL doesn't really show up anything untoward.
However, I found that if I subtly changed the cursor SQL, (so that it did the same thing, but was written differently), it fixed the performance problems.
where ade_start_date between cpDate-cpDays and cpDate-1
/*and ade_start_date < cpDate
and ade_start_date >= (cpDate-cpDays)*/
From this, we thought that there may have been a bad cached execution plan which the change of code forced a recalculation of. However, about 2 hours later, the changed code ran slowly again. So a further subtle change was made, which fixed the issue again. Until this morning, when it was running slowly again.
This feels like it is CBO/stats related potentially, but is out of my area of knowledge unfortunately. We have our DBA investigating this, but there may be things I can test to narrow down the possibilities in the meantime.
I have big trouble with some Update query on Oracle 11G.I have a set of tables (5) of identical structures and a view that consists in an UNION ALL of the 5 tables.None of this table contains more than 20 000 rows.Let's call the view V_INTE_NE. Each of the basic table has a PRIMARY KEY defined on 3 NUMBERS(10,0) -> INTE_REF / NE_REF / INSTANCE.
Now, I get 6 rows in another table and I want to update my view from the data of this small table (let's call it SMALL). This table has the 3 columns INTE_REF / NE_REF / INSTANCE.
When I try to join the two tables :
SELECT * FROM T_INTE_NE T2
WHERE EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
I get the 6 lines in 0.037 seconds
When I try to update the view (I have an INSTEAD OF trigger that does nothing (just return for testing even without modifying anything), I execute the following query :
UPDATE T_INTE_NE T2
SET INTE_STATE = -11 WHERE
EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
The 6 rows are updated (at least TRIGGER is called) in 20 seconds.
However, in the execution plan, I can't see where Oracle takes time to achieve the query :
Plan hash value: 907176690
[code]....
Predicate Information (identified by operation id):
2 - access("T2"."INTE_REF"="T1"."INTEREF" AND "T2"."NE_REF"="T1"."NEREF" AND
"T2"."INTE_INST"="T1"."INSTANCE")
Note- dynamic sampling used for this statement (level=2)
Statistics

0 commit cleanout failures: cannot pin
[code]....
I get exactly the same execution plan (when autotrace is ON).Furthermore, if I try to do the same update on each of the basic tables, I get the rows updated instantaneously.
I'm using PreparedStatement to execute a query with some parameters. in sql developer, it just spends 12 seconds but in jdbc, it's around 140 seconds.
I disabled "_optim_peek_user_binds" parameter already but it didn't work. alter session set "_optim_peek_user_binds"=false;
I am using 11gR2 on windows server. This is the query that runs many times a day and effect badly the performance of database. I don't have much idea about this query.

FROM sys.dba_audit_session
WHERE returncode != 0 AND TO_CHAR(timestamp, 'YYYY-MM-DD HH24:MI:SS') >= TO_CHAR(current_timestamp - TO_DSINTERVAL('0 0:30:00'), 'YYYY-MM-DD HH24:MI:SS')
I have an Oracle database (9.2.0.7) installed on a HP-UX server.When trying to access this database from another HP-UX or Linux server, connection is fine. But when trying to connect from a Windows based client, connection is very slow (almost 1 minute to return the result of a 'select count(*)' like query, which is immediate from the Linux client).
Here are some facts I can add :
- Clients and servers are on the same network segment (it is not a network matter)
- No matter which client version I use, there no difference
- I tried to know what happens on the Oracle server when performing my sample query using tusc command : the result is that the server is performing exactly the same actions when sending my query from a Linux client or a Windows client
- The only relevant difference seems to be the client OS

I am working in EBS 11i and database 9i. I know that we can not write subquery in IF condition like below.
IF deptno IN (select deptno from dept)
--
END IF;
Is there any alternative to achieve above scenario.
The Scenario is that we have to restrict clients to write file on C drive for which we have to grant admin privileges(OS) which we don't wanna give. Rather they can write on their own profile.
In CMD we can find their profile with %userprofile% command,but i am confused of using it in oracle form. so is there any possibilities to redirect O/P to userprofileyour_file.txt
Just for an instance ,code is like this which is currently writing in C: drive
