1)How a single control file is enough to have all the transaction's SCN no for older transactions.
Eg - A transaction has the SCN 01 and after a month the new transaction's SCN is 502. Is the control file holding all those (01 to 502) SCN in it or just will have the latest SCN no (ie - 502).
I am trying to create a new controlfile. I used "alter database backup controlfile to trace;" and then I copied and pasted the contents of the trace file into the .sql file. My sql script is
CREATE CONTROLFILE SET DATABASE "FIVESTAR" RESETLOGS NOARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 292
[code]....
Actually, the name of my database was 'STAR' and I changed it to "FIVESTAR" int this .sql script. Now when I run this script with SQL> @ <path of my sql script>, it gives me the following errors:
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed
ORA-01504: database name 'FIVESTAR' does not match parameter db_name 'STAR'
I can not run the control file treace file,why?
[oracle@hxl oradata_bak]$ more run_sql.sql
CREATE CONTROLFILE REUSE DATABASE "ORACL" RESETLOGS ARCHIVELOG

I was doing some R&D on my test machine trying to understand how controlfile works. I started up my db and then deleted (renamed)the controlfiles at OS level. I was expecting the db to shutdown. But it dint. Moreover when i queried select name from v$controlfile; it was still reflecting the old controlfile names. To check if it was still functioning, i created a new tablespace with one file and it also got created without any error.
What i dint understand is how could the db still be running when the control file was'nt there and new tablespace and datafile get created? As i understand, whenever a new file is created, an entry is made in the control file. But when control file dint exist where was the data about new tablespace and datafile written?
I am not able to create control file from scrip . it showing following error
ORA-01081: cannot start already-running ORACLE - shut it down first

What's the maximum size of the control file in one database ?
i calculated it according to the following steps:
SQL>SELECT (BLOCK_SIZE/1024/1024)*20000 MB FROM V$CONTROLFILE WHERE ROWNUM = 1;
MB
------
312.5
The maximum number of the data block in one control file is 20000.
SQL> select block_size from v$controlfile;
BLOCK_SIZE

16384
SQL> show parameter db_block_size;

db_block_size integer 8192
the 2 can have difference block size?
I am using oracle 10g R2. Some how control file is corrupted and database is not open. and there is no backup of control file. Now i need to open the database without recreating the database.

what executable statements in PL/SQL mean? My objectives are:
1)Writing Executable Statements
2)Create PL/SQL executable blocks using DML and transaction control
I have to explain what exactly each is and what should come under it. what kind of statements and what should be covered under executable statements?
I have read almost all docs about distributed transaction on tahihi.oracle.com website,But I can find a statment about this:
Can Oracle always guarrantee the data consistent in a distributed transaction?
For example,there is a distributed transaction on node a,node b and nod c.node b and node c informed node a they were prepared,so node a committed,and inform node b and node c commit.then node b committed and feedback,but network on node c broken at this point,So node a can't not get feedback from node c,but node a and node b has been committed, so what will Oracle do in this condition?
If node c rollback the data on local node, consistent in this distributed transaction was failed ,yes?

Is it possible to use where clause to discard one of the item which is not able to fit into column because of the length constraint.
Example:
1.Remove first digit from the item_ID where ITEM_ID IN (12345)
2.Do not load data WHERE ITEM_ID IN (12345)
I'm having a problem with SQL loader and the control file. I want to load a delimited file. The script will eventually be automated where the file name is passed in to the script, it's not a static name.
It's a simple SQL loader Unix script that I have created as follows
Unix file called test_load
# Auto Load
#
#
export data_file=/dev/test_$1$2.csv;
export ORACLE_HOME=/u01/oracle/product/10.2.0;
export ORACLE_SID=XXX;
export PATH=$PATH:$ORACLE_HOME/bin;
sqlldr userid=XXX/XXX data=$data_file
control=/dev/cntrl/test.ctl
errors=99999
bad=/dev/bad/test_$1$2_$$.bad
log=/dev/logs/test_$1$2_$$.log
the top of my control file is as follows
load data
truncate
into table test
fields terminated by "|"
when record_type = 'AA'
(
running at the prompt ./test_load myload 20100319
The following error occurs
SQL*Loader-350: Syntax error at line 5.
Expecting "(", found keyword when.
when record_type = 'AA'
^
I believe the format of my control file is correct but for some reason it won't load.
I have a csv file extracted from mainframe which has to be loaded into oracle using sqlldr utility.The numbers are in the format +0000003333, -0000003232.44 etc
I have to convert it to 3333 and -3232.44 and insert into the table.
I have used syntax like
Load file....append into table (t_num expression "to_number(':tnum,'99999.999')")
This gives me an invalid number error.
The reason "why sql loader's CONTROL FILE is not working, if that location has space in between"
E.g. - C:practice for sqlloadercontrol1.ctl
But it works if we remove the space in between the path as below:
E.g. - C:practice_for_sqlloadercontrol1.ctl
I tried a lot to load data to table from excel(.csv) using sql*loader the oracle version of sql*loader doesn't support the control file created using notepad(.ctl).Though i given a filename with extension as .ctl it seems as a .txt file. Is there any alternate way to create it?
View 3 Replies View RelatedI am loading data using sqlldr command in UNIX to an oracle table and want to concatenate timestamp to a file name in the "create_file_name" column in the code below.
I have the below code within the control file..
LOAD DATA

file_type POSITION(1:5) CHAR,
business_date POSITION(16:23) DATE "YYYYMMDD",

I am using perl script to dynamically generate the control file.If I have data in the control file as well as in the datafile, how would i write the control file in that case. Is the below one correct?

INSERT INTO TABLE EMP fields

trailing nullcols

Is there any way that if my control file contains half of the data and my data file contains the other half of the data can i club this data into a logical record in the control file to populate the DB?
My exact 2nd requirement is, my DB contains 5 cols and for 1 col the data is common(countryName) which i have to pass to the control file dynamically and the .csv file contains the data for the other four cols. How could i combine these in the ctrl file and populate the DB?
so if the DB contains CountryName, empid, ename, sal and dept..I will get the CountryName to the ctrl file and csv contains the data for empid, ename, sal and dept. How would i combine these data into a logical record and populate the DB?

View 1 Replies View RelatedI am trying to generate dynamic control file, as the files I want to upload are coming from different source and their name is constantly changing but following a fix pattern and naming convention.
I am able to generate dynamic control file through SQL. But while calling from BATCH file, i am unable to sent the file name as parameter.
All the examples i have searched are for UNIX, how to do it with BATCH File in WINDOWS.
I have a control file like following:
LOAD DATA
INFILE *
INTO TABLE member
REPLACE
FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
(
control_id,
name,
address
)
problem is that control_id value is not in data file and I have to assign to each row the same value generated from sequence or from unix variable.
For example, after I run sqlldr, I have to have records in the table like following:
control_id name address
---------- ---- -------
1847 Charlie 250 yonge st
1847 Peter 5 Brookbanks dr
1847 Ben 123 King st

How do I do that?
