I am building a database to store call quality statistics for VOIP networks. It is a very insert heavy application, and data reliability is of relatively minimal importance (in the sense that a few corrupt call records here and there doesn't matter the way corruption does in for example a banks database). Long term storage is also unimportant, most customers only wish to keep 3 months of data readily available in the database. Most do not even archive the older data.
To that end I am searching for every possible way to improve my insert performance and the internet has turned me onto the idea of NOLOGGING. These are the steps I have taken to reduce my IO consumed by the Redo and Undo logs.
1. I am inserting with the APPEND_VALUES hint.
2. I have disabled force logging at the database level
3. I have disabled force logging at the tablespace level
4. I have disabled logging on the relevant table and each of its indices
As best I can tell this is all I can do to minimize Redo/Undo, but based on my observations of the Disk portion of the WinServer2008 Performance Monitor, this has made little to no change in the amount of IO to my REDO and UNDO files. IO to the .dbf containing my table makes up less than 20% of the total disk IO for oracle.exe, the rest is the REDO and UNDO logs.
The above article is a little over my head but I am able to extract from it that I will never entirely eliminate REDO/UNDO, which is fine, but I would think I could get it lower than it currently is.ted.
I am aware that from 11g, memory_target is sufficient for memeory management between SGA and PGA.
what happens if MEMORY_TARGET set to non-zero and SGA_TARGET set to zero values in a 11g database? Does it enable automatic memory management within the SGA?
We regularly hit by ORA-4031 errors. Also, memory_target advisory (v$memory_target_advice) does not show any advisory information.
for eg: memory_max_target = 500m memory_target = 500m
Now we are having 100+ sql queries and we making all those queries as procedures.after that we want to schedule those procedures and get data to export into excel file.
so we are planning to use utl_file to get data export excel. we may have rows of 30000 above.is it utl_file will be able upload all these rows into excel.any performance issue will come.
I need to take only backup of schema objects with out data using exp (export) into .sql file and need to run that .sql file in the target.because I dont have exp/imp privs on target database.
but it will return me below error, i have only access to user shan our client cant allow me to use system or sysdba schema or any other required grants or privileges so is there any way to take metadata backup of user shan from user shan.

I am exporting a table that is 3 GB in size and also Partitioned with option NOCOMPRESS specified.
Now when i export it with COMPRESS=N option of exp utility then it should take 3 Gb in target server but will exporting it with COMPRESS=Y will save some storage during import or once NOCOMPRESS option specified on partition has no impact on exp utility COMPRESS=Y option and it will take 3 GB space in both cases
Is this true that whether u specify COMPRESS=N|Y during export it does not matter the size will be 3 GB always after import?
I would like to export few tables from the physical standby which is in read only mode.
I have tried both the exp and expdp methods and could successfully export and import the tables from physical standby using exp unfortunately the expdp does not allow this process from a read only database.
Does this mean that we still have to use the exp feature instead of expdp ?
Note : I would expect a proper response from experts and no unwanted comments like "Contact Oracle support" or "Paste the entire command here" or "Read the Manuals" or "Why i am exporting from Standby and not from Primary" etc.
extract a huge amount of data from a couple of views... the problem is that they want it in TXT files with fixed record length. There will be like 6 files, for a total amount of about 10GB.
export those tables in the fastest possible way? If I'm not mistaken exp and expdp can't create txt files, so do I really need to use utl_file or spool?
i have to export data from emp table which has address column and address column contain comma, when i am running below script, the comma part in address field comes in next tab in csv file, is there any way we can avoid shifting to next tab and can have complete address in one tab.

I am trying to export a partition of a table and import it to another database. I get the below error when I try to import.
ORA-14400: inserted partition key does not map to any partition
If I export the table(for that particular partition) and import the table(after dropping the table) in destination, the partitions and sub partitions are created without any problem.
The table is Range Partitioned and Sub partitioned in List. So I had to perform the below operation if I want to retain other data in the Destination table.
1. Drop the existing partition 2. Create the partition and sub partition, same as source 3. Execute imp
In fact I had to perform step#2, as if I split the partition also, the sub partition gets replicated in the new partition, which again throws the same error. Is there better way of managing the partitions and subpartition in destination with exp/imp utility, so that I need not perform step#1 and step#2 manually.
I have added a bitmap image in my workbook but when i am exporting it into excel or HTML ,only text part of the title is exporting into excel file . The bitmap is only visible in discoverer workbook ,after exporting to excel or HTML, it disappears,
In one of my projects I am exporting a couple of views into a flat file. The export utility is generic and uses dynamic sql to generate a flat file. We have a test environment and a production environment. On both the code is the same. We noticed that the output is different between the environments although it is supposed to be the same. If I export a view in the production I will get a record like this:
The code I am running is not changing any settings explicitly. It looks like this and it will be run as EXECUTE IMMEDIATE:
DECLARE v_sql VARCHAR2 (32000); v_sql_count NUMBER := 0; v_error VARCHAR2 (4000); v_new_file UTL_FILE.file_type; BEGIN [code]........
I also tried to do the following on production in order to get it equal to the test environment:
BEGIN EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_LANGUAGE = AMERICAN ' || 'NLS_NUMERIC_CHARACTERS = ''.,''' || 'NLS_TIMESTAMP_FORMAT = ''DD-MON-RR HH.MI.SSXFF AM'''; END;
This would change the formatting for the timestamp columns for almost all files. Almost. Two of those files remain unchanged and still show the decimal separator from the old setting:
Looking to understand the difference between instance tuning and database tuning.
What is the difference between these two tuning exercises? I understand that an instance is memory based structures (logical) where as database consists of physical structures.
However, how does one tune a database the physical structure? Does it have to do with file placements/block sizes etc. Would you agree that a lot of that is taken care by ASM now in 11g? What tools are required/available (third party as well as oracle supplied) for these types of tuning scenarios?
I'm trying to export a relatively large database but it's a bit more complicated than that.For one schema I need a full export / import (data included).
For another 10 schemas I need them empty, with the exception of a table in some of them which needs to be exported / imported with all data inside.Is it possible to do this with datapump utility (impdp, expdp)?
Afterwards I will be running some scripts to populate the DB instance with critical data / metadata.
i'm working on sql developer my table contains 40 columns and contains around 4 to 5 lakhs records........
when i'm trying to export the results into excel or text file my sql developer is getting hanged... if the result is less than 2lakh record its copying....
I have taken database backup using exp command and when I try to import in other pc the foreign keys are not imported. It saying error message that no matching unique key or primary key for this column.
how will i take backup including with primary keys?
Sunddenly my exports hangs at 'exporting cluster definitions'. I had been using this database since last 4 years and it never cause a problem or hangs at this level. here i'm pasting my screen details. it is my production db.

I want to export the oracle data into an excel sheet. I have written the code by using UTL_FILE package. but i am getting the output as shown in the screen shot(without formatting the column size as the width of the data it has). But I want the output column width to be set according to the size of the data automatically.
