What Is SQL*Loader?
What Is a SQL*Loader Control File?

How To Export Several Tables Together?
What Happens If the Imported Table Already Exists?
How To Import One Table Back from a Dump File?
What Are the Original Export and Import Utilities?
How To Invoke the Original Export Import Utilities?
Sample scripts used in this FAQ assumes that you are connected to the server with the HR user account on the default database instance XE. See other FAQ collections on how to connect to the server.
Some sample scripts may require database tables created by other samples in the beginning of the collection.
What Is the Simplest Tool to Run Commands on Oracle Servers?
The simplest tool to connect to an Oracle server and run commands to manage data is SQL*Plus. It is an Oracle database client tool that works as a command-line user interface to the database server. SQL*Plus allows you:

Format, perform calculations on, store, and print from query results.
Examine table and object definitions.
Develop and run batch scripts.
Perform database administration.
What Is the Quickest Way to Export a Table to a Flat File?
The quickest way to export a table to a flat file is probably to use the SQL*Plus SPOOL command. It allows you to record SELECT query result to a text file on the operating system. The following tutorial exercise shows you how control the output format, start the spooler, and dump all record from a table to a flat text file:
>mkdir \oraclexe\test
>sqlplus /nolog

SQL> connect HR/fyicenter

SQL> SET HEADING OFF;
SQL> SET FEEDBACK OFF;
SQL> SET LINESIZE 1000;
SQL> SPOOL \oraclexe\test\employees.txt;
SQL> SELECT * FROM EMPLOYEES;
……
SQL> SPOOL OFF;
You should get all records in employees.txt with fixed length fields.
How To Export Data with a Field Delimiter?
The previous exercise allows you to export data with fixed field lengths. If you want export data with variable field lengths and field delimiters, you can concatenate your fields with an expression in the SELECT clause as shown in the tutorial exercise bellow:
SQL> SET HEADING OFF;
SQL> SET FEEDBACK OFF;
SQL> SET LINESIZE 1000;
SQL> SPOOL \oraclexe\test\fyi_links.txt;
SQL> SELECT id ||’,'|| url ||’,'|| notes ||’,'|| counts
||’,'|| created FROM fyi_links;
……
SQL> SPOOL OFF;
You should see all records in fyi_links.txt with ‘,’ delimited fields as shown here:
101,fyicenter.com,Session 1,,17-MAY-06
110,centerfyi.com,Session 1,,17-MAY-06
What Is SQL*Loader?
SQL*Loader is a database tool that allows to load data from external files into database tables. SQL*Loader is available as part of the free Oracle 10g Expression Edition. It has some interesting features as:

Can load data from multiple data files into multiple tables in one load session.
Can specify character set of the data.
Can generate sophisticated error reports.
Can load data directly to Oracle datafiles, bypassing normal record inserting process.
What Is a SQL*Loader Control File?
A SQL*Loader control file a text that defines how data files should be loaded into the database. It allows you to specify:

Where is the input data file.
The format of the input date file.
The target table where the data should be loaded.
How input data fields should be mapped to target table columns.
Select criteria to select input records for loading.
Where to output errors.

11g pro*c appliation crashes while 10g is ok, why?

November 19, 2009 at 7:40 am · Filed under Oracle ·Tagged

11g pro*c appliation crashes while 10g is ok, why?

My 10g pro*c application works perfectly, recently
I upgraded it to 11g, but it keep crashing, why?

How to resolve this issue?

Why I am posting this way is

I want to know if there any known bug for 11g to support pro*c?

Because my application works perfectly under 10g.
while compile using 11g it always crash on query, insert etc.
My app is linking the library clntsh

Further study my issue, found it crashed on opening cursor.

ORACLE is quite strange on if there’s not enough cursor.
9i will give a error message.
10g will be ok, no error.
11g will crash.

I am really just confused.
should I add the MAXOPENCURSORS to specify the cursors?

lrwxrwxrwx 1 oracle oinstall 17 Nov 4 12:36 libclntsh.so -> libclntsh.so.10.1
-rwxrwxr-x 1 oracle oinstall 21524515 Nov 4 12:36 libclntsh.so.10.1

11g is
$ ls -lt libclntsh.so*
-rwxrwxr-x 1 oracle oinstall 36972682 Dec 4 11:42 libclntsh.so
-rwxrwxr-x 1 oracle oinstall 0 Nov 7 2007 libclntsh.so.11.1
why libclntsh.so.11.1 is size 0? Anything wrong with the env?

Is that because of the stack size?
I am still struggling for the oracle bug.
maybe I should wait for 11.2.0

Ever find the source to your issue? I have a similar situation with an oracle 11 process I am building. Here is the stack trace:

=>[1] _kill(0×0, 0×6, 0×1, 0x3e388, 0x1d2a1e4, 0xfef6e308), at 0xfef4559c

[8] 0xb8024dd5(), at 0xb8024dd5

Any assistance is appreciated.

Partitioning a Table in Oracle

November 19, 2009 at 7:35 am · Filed under Oracle ·Tagged

Below is the procedure of partitioning a table in oracle.

1) Identify the table creation script that you want to do partitioning. There are many tools to do it or you can use DBMS_METADATA package’s GET_DDL procedure to do the task.

2) Identify the index creation script of the table that you want to do partitioning. There are many tools to do it or you can use DBMS_METADATA package’s GET_DDL procedure to do the task.

3) Identify the constraints on the table that you want to do partitioning. There are many tools to do it or you can use DBMS_METADATA package’s GET_DDL procedure to get the script of constraints.

4) Create the partitioning table. An example of partitioning table version of login table is given below.

5) Insert data into the partitioning table: You can wish any method to do it. Like export import , or normal insert operation, or for faster insert use /*+APPEND NOLOGGING */ hint.

6) After data loaded into partitioned table rename the original table and make the partitioned table to desire one.

7) Build index and constraints of the partitioned table and consider whether partition the index.

8) Gather statistics on the partitioned table.

1)Using DBMS_METADATA.GET_DDL take the original table script.

2)Verify that the source table is able to undergo an ONLINE redefinition using the dbms_redefinition.can_redef_table procedure.

3)Create an empty interim table reflecting the final structure. If you want keep index, constraints same as in source table then don’t add or modify constraints.

4)Start the redefinition of the source table using the dbms_redefinition.start_redef_table procedure.

5)Copies the dependent objects of the original table onto the interim table by the COPY_TABLE_DEPENDENTS Procedure.

6)Finish the redefinition of the source table using the dbms_redefinition.finish_redef_table procedure.

7)Drop the interim table.

It is recommended to periodically synchronize the interim table with the source one when a large amount of DML is executed on the table while the
re-organization is taking place by calling the dbms_redefinition.sync_interim_table() procedure.

Introduction to Oracle: SQL and PL/SQL 1Z0-001

Exam details

Exam number  1Z0-001 
Name of exam   Introduction to Oracle: SQL and PL/SQL 
Number of questions  57 
Timer  120 minutes 
Passing score  68 
Comments  For more details about this exam click here

The authors explain the concepts very well. Some of the explanations, like for why you would want to use a specific rollback segment or why permissions on procedures have to be granted directly are handled better than I’ve seen anywhere else. The examples that go along with these explanations are clear and not contrived like some other books.

oracle runInstaller needs minimum oslevel : 5300-05-06

November 19, 2009 at 7:31 am · Filed under Oracle ·Tagged

I am trying to install 11g R1 on AIX 5.3.8, but getting error: runInstaller needs minimum oslevel : 5300-05-06
I’ve have 10.2 already running on this server.
I’ve tried ./runInstaller -ignoreSysPrereqs
The Unix boys have verified that all the the required libraries are at the correct version

Any other suggestions?

You have to upgrade your AIX oslevel,that’s more than the libraries mentioned in the installation guide. See this IBM website for a principal discussion,although the OS staff should be aware of this:

http://www.ibm.com/developerworks/aix/library/au-dutta_work.html

And it’s correct,11g requires a higher level.

Werner

NEVER take the word of your Unix admins! What a bunch of bullshit. Running OSLEVEL -R will tell you if you are really up to date with your patches.
