Sql loader suggestion

LOAD DATA
INFILE /home/dir1
BADFILE abc.bad
truncate
into table tab1
fields terminated by ','
optionally enclosed by '"'
col1,
col2,
col3,
col4
here my table tab1 structure
col1 number
col2 number
col3 Varchar
col4 varchar
when i load the record like
1,1,1,2 it is also getting loaded.
but i need to load records like 1,1,a,b
what i feel.
is the control file is wrong somewhere so that it is taking the numeric datatype to character columns of the tab1 table.
can i make something in the control file so that it will accept data like (1,1,a,b) and not the (1,1,1,2) one
thanks

What do you want it to do when it comes across a row of data in the file that is e.g.
1,1,1,2
At the moment it is assuming that the last two are character datatype and as such creating them quite correctly in your table.
Perhaps you want to be selective about your data. See this link...

Need suggestions for imporving data load performance via SQL Loader

Hi,
Our requirement is to load 512 (1 GB each) files in Oracle database.
We are using SQL loaders to load files into the DB (A partitioned table) and have tried almost all the possible options that come with sql loaders (Direct load path, parallel=true, multithreading=true, unrecoverable)
As the tables is growing bigger in size, each file load time is increasing (It started with 5 minutes per file and has reached 2 hours per 3 files now and is increasing with every batch- Note we are loading 3 files concurrently on the target table using the parallel = true oprion of sql loader)
Questions 1:
My problem is that somehow multithreading is not working for us (we have multi CPU server and have enabled multithreading=true). Could it be something to do with DB setting which might be hindering the data load to be done in multiple threads?
Question 2:
Would gathering stats on the target table and it's partitions help improve load performance ? I'm not sure if stats improve DML's, they would definitely improve sql queries. Any thoughts?
Question 3:
What would be the best strategy to gather stats on this table (which would end up having 512 GB data) ?
Question 4:
Do you think insertions in a partitioned table (with growing sizes) would have poor performance as compared to a non-partitioned table ?
Any other suggestions to improve performace are most welcome !!
Thanks,
Sachin

2 hours to load just 3 GB of data seems unreasonable regardless of the SQL Loader settings. It seems likely to me that the problem is not with SQL Loader but somewhere else.
Have you generated a Statspack/ AWR/ ASH report to see where all that time is being spent? Are there triggers on the table? Are there bitmap indexes?
Is your table partitioned in a way that is designed to improve the efficiency of loads so that all the data from one file goes into one partition? Or is data from each file getting inserted into many different partitions.

Need suggestions on loading 5000+ files using sql loader

Hi Guys,
I'm writing a shell script to load more than 5000 files using sql loader.
My intention is to load the files in parallel. When I checked the maximum number of sessions in v$parameter, it is around 700.
Before starting the data load, programmatically I am getting the number of current sessions and maximum number of sessions and keeping free 200 sessions without using them (max. no. of sessions minus 200 ) and utilizing the remaining ~300 sessions to load the files in parallel.
Also I am using a "wait" option to make the shell to wait until the 300 concurrent sql loader process to complete and moving further.
Is there any way to make it more efficient? Also is it possible to reduce the wait time without hard coding the seconds (For Example: If any of those 300 sessions becomes free, assign the next file to the job queue and so on..)
Please share your thoughts on this.
Thanks.

My intention is to load the files in parallel. When I checked the maximum number of sessions in v$parameter, it is around 700. Concurrent load you mean? Parallel processing implies take a workload, breaking that up into smaller workloads, and doing that in parallel. This is what the Parallel Query feature does in Oracle.
SQL*Loader does not do that for you. It uses a single session to load a single file. To make it run in parallel, requires manually starting multiple loader sessions and perform concurrent loads.
Have a look at Parallel Data Loading Models in the Oracle® Database Utilities guide. It goes into detail on how to perform concurrent loads. But you need to parallelise that workload yourself (as explained in the manual).

Also is it possible to reduce the wait time without hard coding the seconds (For Example: If any of those 300 sessions becomes free, assign the next file to the job queue and so on..)Consider doing it the way that Parallel Query does (as I've mentioned above). Take the workload (all files). Break the workload up into smaller sub-workloads (e.g. 50 files to be loaded by a process). Start a 100 processes in parallel and provide each one with a sub-workload to do (100 processes each loading 50 odd files).
This is a lot easier to manage than starting for example a 5000 load processes and then trying some kind of delay method to ensure that not all hit the database at the same time.
I'm loading about 100+ files (3+ million rows) every 60 seconds 24x7 using SQL*Loader. Oracle is quite scalable and SQL*Loader quite capable.

SQL*Loader and DECODE function

Hi All,
I am loading data from data files into oracle tables and while loading the data using SQL*Loader, the following requirement needs to be fulfilled.
1) If OQPR < 300, RB = $ 0-299, SC = "SC1"
2) If 300 < OQPR < 1200, RB = $ 300-1199, SC = "SC2"
3) If 1200 < OQPR < 3000, RB = $ 1200-2999, SC = "SC3"
4) If OQPR > 3000 USD, RB = > $3000, SC = "SC4"
Here OPQR is a field in the data file.
Can anyone suggest how do we handle this using DECODE function? Triggers and PL/SQL functions are not to be used.
TIA.
Regards,
Ravi.

The following expression gives you different values for your different intervals and boundaries :
SIGN(:OQPR - 300) + SIGN(:OQPR - 1200) + SIGN(:OQPR - 3000)

How to have more than one condition on same column --- using SQL Loader

Hi All,
I am stuck with SQL Loader..
How do I filter records before loading in the table using when clause..
i should load data only when
field1 = 'AC' or 'VC'
field2 is NULL
i used various combinations in when clause like
a) when field1='AC' or field1='VC' and field2 = BLANKS
b) when (field1='AC') and (field2 = BLANKS )
& similar...
In all the cases I tried I could not implement OR condition with field1 and null condition with field2
but my main concern is can we use OR or IS NULL things in when clause of SQL Loader..
is it possible to check this anywhere??
any alternate solution u could suggest??
Thanks
Dikshit

Ok I'll try that, although I did try it earlier when I had iTunes 5.xx loaded, I think.
As to size of playlists, I have a master (900 songs) that defines what will fit onto the ipod , I then generate all the others as subsets of the master (not of the library)- hence I know they will all fit
Can you also clarify something for me: the dialogue box we are discussing is intended, I think, so that one can set the automatic synching of certain playlists between the PC & the ipod. Is that the only way one can select other playlists to go to the ipod - i.e. as static once-offs, not synchronised ?
Apple' docs, I think, are poor in this regard - they assume most ipods are bigger then the users song library and they gloss over the details of this alternate mode of playlist synching.
Thanks - Nick

Sql@loader-704 and ORA-12154: error messages when trying to load data with SQL Loader

I have a data base with two tables that is used by Apex 4.2. One table has 800,000 records . The other has 7 million records
The client recently upgraded from Apex 3.2 to Apex 4.2 . We exported/imported the data to the new location with no problems
The source of the data is an old mainframe system; I needed to make changes to the source data and then load the tables.
The first time I loaded the data i did it from a command line with SQL loader
Now when I try to load the data I get this message:
sql@loader-704 Internal error: ulconnect OCISERVERATTACH
ORA-12154: tns:could not resolve the connect identifier specified
I've searched for postings on these error message and they all seem to say that SQL Ldr can't find my TNSNAMES file.
I am able to connect and load data with SQL Developer; so SQL developer is able to find the TNSNAMES file
However SQL Developer will not let me load a file this big
I have also tried to load the file within Apex (SQL Workshop/ Utilities) but again, the file is too big.
So it seems like SQL Loader is the only option
I did find one post online that said to set an environment variable with the path to the TNSNAMES file, but that didn't work..
Not sure what else to try or where to look
thanks

Hi,
You must have more than one tnsnames file or multiple installations of oracle. What i suggest you do (as I'm sure will be mentioned in ed's link that you were already pointed at) is the following (* i assume you are on windows?)
open a command prompt
set TNS_ADMIN=PATH_TO_DIRECTOT_THAT_CONTAINS_CORRECT_TNSNAMES_FILE (i.e. something like set TNS_ADMIN=c:\oracle\network\admin)
This will tell oracle use the config files you find here and no others
then try sqlldr user/pass@db (in the same dos window)
see if that connects and let us know.
Cheers,
Harry

Your table and view don't make sense so I created a "dummy" table to match your .ctl file.

SQL Loader need to insert the input filename into output table

Hi All,
I've a small problem with my SQL Loader query. My sql loader should read a file and write the data into a file. Also this sql loader should read the filename and write it into the same table. Here's my control file code:
LOAD DATA
APPEND
INTO TABLE XXMW_STG_SOH_HEADER_UK
WHEN (1:4) = '7010'
TRAILING NULLCOLS
(WH POSITION(5:6)
,ITEM POSITION(9:26)
,PRODUCT_STATUS POSITION(33:34)
,BALANCE_ON_HAND POSITION(35:43)
,TO_SHIP_QTY POSITION(71:79)
,RUSH_TO_SHIP_QTY POSITION(80:88)
,RESERVED_QTY POSITION(175:183)
,SNAPSHOT_DATE POSITION(134:143) CHAR "TO_DATE(:SNAPSHOT_DATE,'YYYY-MM-DD')"
,SNAPSHOT_TIME POSITION(144:151) CHAR "TO_DATE(:SNAPSHOT_TIME,'HH24:MI:SS')"
,PROCESSED_IND CONSTANT "N"
,PROCESSED_DATETIME SYSDATE
,_FILENAME POSITION(184) CHAR TERMINATED BY WHITESPACE_
My program should read the filename dynamically (means a shell script is calling this .ctl file which is reading multiple input files) and insert into the filename field in xxmw_stg_soh_header_uk table.
Please let me know for any questions/clarifications.
Regards,
Debabrata

While I think Blu's suggestion to use external tables is better, if you need to use SQL Loader, you could do something like this.
Create a "generic" control file with a placeholder for the filename, something like:
LOAD DATA
APPEND
INTO TABLE XXMW_STG_SOH_HEADER_UK
WHEN (1:4) = '7010'
TRAILING NULLCOLS (
   WH POSITION(5:6),
   ITEM POSITION(9:26),
   PRODUCT_STATUS POSITION(33:34),
   BALANCE_ON_HAND POSITION(35:43),
   TO_SHIP_QTY POSITION(71:79),
   RUSH_TO_SHIP_QTY POSITION(80:88),
   RESERVED_QTY POSITION(175:183),
   SNAPSHOT_DATE POSITION(134:143) CHAR "TO_DATE(:SNAPSHOT_DATE,'YYYY-MM-DD')",
   SNAPSHOT_TIME POSITION(144:151) CHAR "TO_DATE(:SNAPSHOT_TIME,'HH24:MI:SS')",
   PROCESSED_IND CONSTANT "N",
   PROCESSED_DATETIME SYSDATE,
   FILENAME CONSTANT ":FILE"I am assuming that your shell script is looping through a set of file names and loading each one. So make your shell script look something like:
FILES=`ls *.txt`
CTL=generic.CTL
for f in $FILES
do
   cat $CTL| sed "s/:FILE/$f/g" > $f.ctl
   sqlldr usr/passwd control=$f.ctl data=$f
doneThe line cat $CTL| sed "s/:FILE/$f/g" > $f.ctl will create a "custom" control file for each file and add the filename as a constant at the end.

ORA-00936 error from SQL expression in SQL*Loader script

I am getting the above error on the following line in my SQL*Loader script:
DIA_CLM_RES_OID DECIMAL EXTERNAL
"SELECT N_ORG_ENTY_ID FROM TESTG4.ORG_ENTITY
WHERE N_USER_ID =
(SELECT UNIQUE WSR_NT_ID FROM CONV_CLM_RESOURCE
WHERE CLM_RES_OID = :DIA_CLM_RES_OID)",
What I am basically trying to do is a 2-table lookup of a value:
1. Find a row in table CONV_CLM_RESOURCE where the value in column CLM_RES_OID matches the value in the input file in field DIA_CLM_RES_OID.
2. Take the value of field WSR_NT_ID from that row and use it to find a row in table TESTG4.ORG_ENTITY.
3. Take the value of field WSR_NT_ID from that row and set it in the target table in field DIA_CLM_RES_OID.
In other words, I am essentially trying to translate the input value by using two other tables to lookup the value to translate to. However, no matter how I arrange it, I keep getting the "ORA-00936: missing expression" error on this statement.
Can anyone see what I am doing wrong, or perhaps suggest a better way of accomplishing a two-table translation of a value?
Thanks!

Still not sure why this doesn't work, but I was able to create and use a function to do this instead, which is probably a better approach anyway.

SQL*Loader and NLS

I am running SQL*Loader 8.1 on an NT4-SP5 environment and getting a 282 - unable to locate character set.... The OTN reference on NLS is not clear on what to run to get the SQL*Loader program to run a simple ASCII text file into a LOAD/APPEND DDL statement. Any suggestions?

In control file replace:
MATUR_DT POSITION(78:85) DATE 'YYYYMMDD',
OR
On WinDoze, edit registry and set NLS_DATE_FORMAT to YYYYMMDD
On *nix set NLS_DATE_FORMAT environment variable to YYYYMMDD

SQL Loader and INSERT Trigger

I have problem and your help to solve it would be very much appreciated.
I am uploading a text file with SQL Loader into a table. Since I used APPEND option in the Loader, I don't want records to be duplicated. So, I wrote a "BEFORE INSERT .. FOR EACH ROW" trigger to check whether that row already exists or not.
For example, let us consider a table TEST as follows.
Fld1     NUMBER(2);
Fld2     VARCHAR2(10);
Fld3     VARCHAR2(10);
I have a trigger on this table.
CREATE OR REPLACE TRIGGER Trg_Bef_Insert_Test
BEFORE INSERT ON Test FOR EACH ROW
DECLARE
vCount NUMBER(2);
DuplicateRow EXCEPTION;
BEGIN
SELECT Count(*) INTO vCount FROM Test
     WHERE fld1 || fld2 || fld3 = :new.fld1 || :new.fld2 || :new.fld3;
IF vCount > 0 THEN
     RAISE DuplicateRow;
END IF;
EXCEPTION
WHEN DuplicateRow THEN
     Raise_Application_Error (-20001,'Record already exists');
WHEN OTHERS THEN
     DBMS_OUTPUT.PUT_LINE('ERROR : ' || SQLCODE || '; ' || SUBSTR(SQLERRM, 1, 150));
END;
Please refer to the following SQL statements which I executed in the SQL Plus.
SQL> insert into test values (1,'one','first');
1 row created.
SQL> insert into test values (1,'one','first');
insert into test values (1,'one','first')
ERROR at line 1:
ORA-20001: Record already exists
ORA-06512: at "CAMELLIA.TRG_TEST", line 13
ORA-04088: error during execution of trigger 'CAMELLIA.TRG_TEST'
Would anyone tell me why do errors -6512 and -4088 occur ?
Also, if you have any other suggestion to handle this situation, please let me know.
By the way, I am using Oracle 8.1.7.
Thank you.

SQL Loader and Error ORA-01847/ORA-01839

Hi,
While using the direct loading in SQL-LOADER when we get the ORA-01847/ORA-01839 all the other records are getting errorred out. It goes fine with the conventional loading.
Should I use some parameters or anything to make sure that all the other records are not rejected when we get the ORA-01847/ORA-01839 error while going with the DIRECT loading.
Thanks
Jibin

In internet I found this short message:
“AL32UTF8 is a multi-byte characterset,that means some characters are stored in more than 1 character, that's true for these special characters.
If you have same table definitions in both databases you likely face error ORA-12899.
This metalink note discusses this problem, it's also applicable to sqlloader:
Import reports "ORA-12899: Value too large for column" when using BYTE semantic
Doc ID: Note:563893.1”
By metalink, I can see the Note linked to a one Oracle Internal Bug for Oracle 11g.....
I'm waiting you suggestion... thanks very much in advance.

Sql loader and bulk data

hi,
I want to insert 100,000 records daily in a table for the first month and then in next month these records are going to be replaced by new updated records.
there might be few addition and deletion in the previous records also.
actually its consumer data so there might be few consumer who have withdrawn the utility and there will be some more consumer added in the database.
but almost 99% of the previous month data have to be updated/replaced with the fresh month data.
For instance, what i have in my mind is that i will use sql loader to load data for the first month and then i will delete the previous data using sqlPlus and load the fresh month data using sql loader again.
1. Is this ok ? or there is some better solution to this.
2. I have heard of external files, are they feasible in my scenario?
3. I have planned that i will make scripts for sqlPlus and Loader and use them in batch files. (OS windows 2003 server, Oracle 9i database). is there some better choice to make all the procedure automatic?
looking for your suggestions
nadeem ameer

I would suggest u use External tables since its more flexible then
sqlloader & is a better option.
For using external tables
1)u will have to create a directory first
2)Generally creation od directory is done by sys,hence after creating the directory
privileges read & write to be provided to user .
3)Creation of external tables.
4) Now use the table as a normal table to insert ,update delete in
ur table.
U can get more information from
http://www.oracle-base.com/articles/9i/SQLNewFeatures9i.php#ExternalTables
Create Directory <directory_name> as <Directory path where file be present>
Grant read,write on directory <directory_name> to <username>
CREATE TABLE <table_name>
(<column names>)
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER
DEFAULT DIRECTORY ,directory_name>
ACCESS PARAMETERS
RECORDS DELIMITED BY NEWLINE
FIELDS TERMINATED BY ','
LOCATION (<filename>)
PARALLEL 5
REJECT LIMIT 200;
Hope this helps.

Substitution for logical OR usage in control file of sql loader

Hi,
can anyone suggest me a substituion method to use the functionality of logical OR in control file developed for sql loader.
Ex:
load data
append
into table ABC
when (1:2) = 'AD'
--AND ((27:28)= '01' OR (27:28)= '02')
AND (1222:1222) = '1'
trailing nullcols
Note: condition commented in the above example need to be replaced.
one way of doing it can be splitting blocks for each condition.
Then it will look like:
load data
append
into table ABC
when (1:2) = 'AD'
AND (27:28)= '01'
AND (1222:1222) = '1'
trailing nullcols
into table ABC
when (1:2) = 'AD'
AND (27:28)= '02'
AND (1222:1222) = '1'
trailing nullcols
So, i'm looking for a better way than this, as i cannot work with the above
splitting logic because i'm dealing with lot many conditions.
Thanx inadvance

Hi,
can anyone suggest me a substituion method to use the functionality of logical OR in control file developed for sql loader.
Ex:
load data
append
into table ABC
when (1:2) = 'AD'
--AND ((27:28)= '01' OR (27:28)= '02')
AND (1222:1222) = '1'
trailing nullcols

SQL*LOADER/SQL usage in Migration

I have very limited migration requirements. I DO NOT need to
migrate a database. I DO need to change some SQL and BCP load
scripts from SQL-SERVER 6.5 to their equivalents in ORACLE 8.0.5.
For this limited purpose, should I proceed to handcode these, or
would the workbench be of use to me?
Thanks for your help.

The migration workbench does, as part of the migration,
generate the BCP and SQL*Loader files required to migrate a
database. However, since you already have the BCP files created
then the Workbench would not actually be able to just generate
the other side of the picture (the SQL*Loader files). I can
suggest the following to you :
1. Perhaps use the Workbench to run a tiny migration that would
show you how we generate the SQL*Loader scripts. It is fairly
straight forward however we need to do some manipulation on
dates.
2. There is a chapter on SQL*Loader as part of the Oracle8i
documentation set.
