We need to simulate load like production environment in test database without actually creating any data volume. Is there any tool which can be used to achieve this, if yes which one is best tool and why?
View 1 Repliesi want to load jpg into my oracle database 10g throw sqlloader
i did folloing steps
step 1)
Create the table as follows
CREATE TABLE image_table (file_id NUMBER(5),
file_name VARCHAR2(30),file_data BLOB);
step 2 )
Create control file as follows
LOAD DATA

step 3)
Then i have run this command

I have one .mdb (Microsoft Access Database) file and it has some tables in it. I had load it once using toad. But now i have to load it frequently into the database. Is it possible using external table, so i can access that tables using "select" statement.

View 1 Replies View RelatedAt the moment, we were loading the file in our system serially. This is a very old and established system.We would like to incorporate parallel loading for our loaders to load data into the database.
Most of the issues would be due to multiple inserts happening due to the files being loaded in parallel. For some reasons, we cannot give regular commits untill the entire batch of items is processed in case the process needs to rollback. A file can contain different set of batch of items clubbed together for loading.
The issue here is untill the first file finishes loading and commits, the second file would just hang. In fact, mulitiple files might hang for the first file to finish. what can I do to overcome this?I tried to used "lock table t1 in SHARE ROW EXCLUSIVE mode nowait". When the leading process is doing inserts, the failing process will fail with a resource busy and acquire with NOWAIT specified. We would catch this exception and redirect that batch to an error file to be reloaded at a later date.
I'm trying to simulate a delete operation through using an update on a trigger my tables are
CREATE TABLE EMPLOYEE (
LNAME VARCHAR(15) NOT NULL,
SSN CHAR(9) NOT NULL,
salary FLOAT,
dno INT NOT NULL,
vst DATE,
vet DATE,
PRIMARY KEY (Ssn));
[code]....
What I want to do is whenever there is an update on vet( valid end time) in employee, delete the values from the employee table and insert the old values from employee into the emp_history table along with the new value for vet. Here's my trigger
CREATE TRIGGER trig4
AFTER UPDATE OF VET ON EMPLOYEE
FOR EACH ROW
BEGIN
INSERT INTO EMP_HIST VALUES( : old.LNAME, : old.SSN, : old.salary, : old.dno, : old.vst, :new.vet);
DELETE FROM EMPLOYEE WHERE(SSN = :NEW.ssn AND vet IS NOT NULL);
END trig4;
//ignore the space between : and o as it makes a smily
The problem is I get an error for a mutating change, what I'd like to know is if the above trigger is possible, and if so how to implement it without giving me an error. I mean it makes sense syntactically and logically(at least to me).
I want to simulate latch : cache buffer chains wait event due to use of nested loop join for lookup tables
This is what a tried :
-- create parent / child tables
SQL>drop table emp1 purge;
drop table dept1 purge;
create table dept1 (dept_id number primary key,
dept_name char(30));
[Code]....
I traced many queries like the one given below (dept_id between 1 and n where n varied from 10 to 1000) but they always result in hash join
1* select d.dept_name, e.id from sys.dept1 d, sys.emp1 e where d.dept_id = e.dept_id and e.dept_id < 1000

what can I do to get a nested loop join to simulate latch : cache buffer chains?
I've always only loaded data into the database by using SQL-Loader and the data format was Excel or ASCII
Now I have to load a XML.
How can I do?
The company where I work has Oracle vers. 8i
I have a data file that looks like:
REC001;TO_NAME;TO_ADDR;TO_PHONE
REC002;ITEM_ID1;DATE_DELIVERED1
REC002;ITEM_ID2;DATE_DELIVERED2
REC002;ITEM_ID3;DATE_DELIVERED3
REC002;ITEM_ID4;DATE_DELIVERED4
i want to load this in the Database using SQL LOADER in this format:
NAME | ADDR | PHONE | ITEM | DATE DELIVERED
-------------------------------------------------
TO_NAME TO_ADDR TO_PHONE ITEM_ID1 DATE_DELIVERED1
TO_NAME TO_ADDR TO_PHONE ITEM_ID2 DATE_DELIVERED2
TO_NAME TO_ADDR TO_PHONE ITEM_ID3 DATE_DELIVERED3
TO_NAME TO_ADDR TO_PHONE ITEM_ID4 DATE_DELIVERED4
Basically i want the name, addr, phone from REC001 to be repeated every time i load REC002.
I wanted to know the best utility in oracle to load data in crores from excel sheets in the database temporary tables in a minimum time.

which tools are available for monitoring load of the database?

infile "E:htmlreportoutput&a_html_broken_jobs_rpt.csv"
here a is the variable name. it will change every 12 csv files once.
or
is there anyother way to achive this?

I'd like to talk about some interesting behaivor with Oracle RAC load balancer.We have Oracle RAC 11.1.0.6 - 2 nodes.
We noticed sometimes the number of sessions { select count(1) from v$session; } was not divided equally between nodes. Also load average was very different between node #1 and node #2.Now we define service explicitly.
srvctl add service -d MYORCL -s MYSERVICE -r MYORCL1,MYORCL2
srvctl config service -d MYORCL -a
MYSERVICE PREF: MYORCL1 MYORCL2 AVAIL: TAF: NONE
After we change connection string of corresponding application(s) the spread will be more equal:
select service_name,inst_id, count(*) the_qty
from gv$session
where service_name = 'MYSERVICE'
group by service_name, inst_id
SERVICE_NAME INST_ID THE_QTY
---------------------------------------------------------------- ---------- ----------
MYSERVICE 1 68
MYSERVICE 2 79
Although it's not round robin algorithm, the distribution looks more equal. It seems explicitly defined service of Oracle RAC has better load balancing approach comparing to the default service (created with db by default).
But there is some downside with more 'equally' distributed load balancing. Consider a client program that is running the following SQL once a 5 minutes:
select ...
from A
inner join B on ...
inner join C on ...
inner join D on ...
where the tables B, C and D data is changing all the time.Once load balancing is distributed more 'equally', the query above will arrive to node #1 and to node #2 more equally. It will cause more interconnect traffic, because Oracle RAC will need to synchronize requested blocks all the time, with much high rate.

i have a problem in my ODI 11g with the load into Oralce table of a fixed width file, i configured all the datasource in ODI and when i do view data i see all correct, the end of file is signed like "0D0A" but when i try my load interface i receive the message that my last field is more big than the one declared.
My file have an header of fields and the last field is a data-field of 2000 characters. I controlled and is really fixed the length cause is a COBOL file from a Mainframe. So it looks that ODI don't understand the end of that field and go ahead to the other, i just tryed to enlarge the limit but is always more big like if the file is shifting on the right.
Have i forgot some configuration in some place? The definition of the file present the end of file like Microsoft hexadecimal \u000D\u000A i try all the combination there but no way to avoid this problem.
