I was given a task by manager to keep track of changes on a given table including os_user who made it.Should I create a trigger on it (on any update, insert, delete etc.) or there is a better way of doing it ?I think there could be some info already in some data dictionary views or something like it.
If I CREATE MATERIALIZED VIEW LOG on that table.
I am trying to delete 3 million records of data from huge table which already consists of 3 billion records.
This is hitting performance of DB and halting other activities of my users. Is there any easy way to delete such data fast. I have tried with forall delete but it is even taking lot of time.
what command is used to create a table by copying the structure of another table including constraints ?

View 2 Replies View RelatedWhat could be the reasons that some queries execute fast when executed on sqlplus on server, whereas the same queries run slower with same input values fed from application screen?
One issue I guess would be bind variable peeking while using application whereas executing from sqlplus is causing hard parsing and thus getting rid of "peeking"
If displaying the data on application screen is taking time after data has been fetched, where I can see this delay?
I understand the elapsed time under 'Fetch' in tkprof will show time taken to fetch from database and not the time taken to be displayed in the application GUI
finally how to set arraysize in jdbc to improve performance by reducing roundtrips?
I have to create a audit/history table on a master table so that I can store the old/current state of data in my audit table. I am planning to write following program.
1. Created the audit table with similar number of records.
2. Everyday at a particular time I will compare the audit/main table and push the records in audit table which are either updated or not present in the audit table so that the audit table = main table + old state of data.
I am unable to figure out the proper way to implement the point 2 above in oracle database.
I'm on 11.2 DB and need to create an audit table that will be populated by DB triggers of other tables (after Insert,Update and Delete). The triggers will only ever be inserting data into the audit table. I have read that for insert only tables, you should define the 'pctfree' as 0. Is this correct? Do I need to set any other params (like pct_used) for tables only ever being inserted into?

I thought that when oracle will update 1st, 2nd & 3rd rows then the sub query will get a count equal to 2, but the time when it goes to update the 4th & 5th row the sub query should get back a count equal to 3 & 4 resp. BUT that is not what exactly is happening!!
I am trying to create a procedure that inserts parameters into a table and then returns the number of rows inserted back to calling block. the procedure is compiling fine but is not returning the number of rows inserted. My code is as follows;
HOST VARIABLE DECLARATION

STORED PROCEDURE
CREATE OR REPLACE PROCEDURE CarMasterInsert_sp (
registration IN VARCHAR2,
model_name IN VARCHAR2,
car_group_name IN VARCHAR2,
date_bought IN DATE,
cost IN NUMBER,
miles_to_date IN NUMBER,
miles_last_service IN NUMBER,
status IN CHAR,
rowsInserted OUT NUMBER)

I think im close just that my syntax is off.
Is there any way I could find the number of inserts happened every day to a particular table.
View 10 Replies View RelatedI have materialized view replication setup in an Oracle 10g environment. Inserts and Updates are being propogated as expected. When a record in the master table is deleted, there are no entries being written to the materialized view logs, and hence, the delete is not propogated to the materialized view on the remote server.
The Materialized View is defined with FAST Refresh and the refesh occurs avery 5 minutes. This allows me to see what entries are written to the mv logs before they are consumed. I thought that all DML statements get written to the mv logs and am lost to explain this behavior. The matser table definition is not very complex. It has a PK defined and two UK Constaints but does not even have any FK constraints defined. There are a couple of triggers defined on this table for Insert, Update and Delete which write audit table records but I can't see how this could affect things. There are no errors being generated on the master table side in the DB or that the application sees.
I am trying to write an update statement which updates the User IDs in one table with the User IDs in another table. However I need to update statement to ignore any duplicates that are in the tables.

View 1 Replies View RelatedIs it possible to create a completely self-contained installer that deploys all the Oracle files along with the application (i.e. the user doesn't need to install instant client, mess around with configuring path environment variables, etc.)?
[URL]
What if as part of the installer, I need to test a connection string entered by the user? That seems to be the sticking point for me. Even after installing the instant client (from the x64 xcopy zip file using install.bat), the installer is not able to connect to the database.
And, the application is 64 bit only (we need the 64 bit Crystal Reports runtime), meaning I've got the 64 bit Oracle instant client installed. I suspect that might be the problem since the msiexec installer process is 32 bit.
I have a form which contains some block (each block with some text item, two radio groups and a list item). I want to enable/disable and set visible property as true/false for first to last items of each block conditionally. I can do that for all items but radio buttons.
Because to set item or radio button property I need to pass that items ID or Name as parameter. I can get items name/type using get_block_property and next item of that item using get_item_property but unable to get radio button ID/Name using get_radio_button_property or any other built in. To execute get_radio_button_property or set_radio_button_property I need to pass radio button ID/Name. So, how I track radio button id or name in oracle forms? Is it limitations of Oracle forms?

You have a stock_amt value in one table and there is a procedure that updates and substracts from this stock_amt.
lets say in a store a have a stock amount of 50 items and this procedure, for each sale is subtracting from this value and it is not allowed to go below zero. The process, beside the update, on this column (set stock_amt = stock_amt - x) is doing a lot of other updates on other tables and it total it takes like 0.5 seconds. Everything is fine till I want to execute this procedure by 50 users in parallel.
The initial implementation, to avoid some dead locks and we put a lock on that column (stock_amt) but there where to much waits. we cannot hold that lock for 0.5 seconds.
What will be the best approach for this? For this stock amt problem, maybe the solution can be a trade like: do not update that column every time but once in a while, by another process or by a materialize view logic.
but what if my column is a critical value like a Prepay balance or bank balance and it needs to be updated in near real time. What will you do?
I'm working on a Oracle Database, and I'm gettin incorrect results when including a date field in the select list which is NULL in the table.
This works correctly and returns exactly one row:
SELECT firstField FROM table WHERE firstField = 'value'
while this doesn't and returns no rows:
SELECT firstField, secondField FROM table WHERE firstField = 'value'
Where secondField is of type date and its value is NULL (00-000-00). Note that the only thing that changes is the select list.
I have several databases that i've recently upgraded from 9i to 11g. With all of them, the automatic stats gathering process has worked just fine every night during the maintenance window.
However, i have this other database that i created and it seems that the only stats being gathered are on the sys and system schemas and not the actual schema that holds all of our tables.
I did some searching, but i'm not sure i was using the right search terms, because i came up empty.

I am looking for a script to find the tbs usage including datafiles. Tablespaces Datafile Size Used Free Used% Free% Max MB
Need all the data in MB and all the datafile space in every tablespace.I have searched internet,but couldn't find this type of format.
1) I have created One tablespace "ABCD" and assigned one user on it "ABCD_AR". I made table through the user and made some transaction.
2) Then I have taken RMAN backup, which include backup of tablespace (ABCD) also.

3) After taking Rman backup, I issued command - "Drop tablespace ABCD including contents and datafiles;"
4) When i issue "LIst backup" through RMAN, its shows blank for the particular tablespace datafile.

Tablespace dropped.

Database closed.
Database dismounted.

how to recover those tablespace's datafile?What happened to earlier tablesapce backup?
we have a database application which is done frequently.in these we load data throught Sql loader, we create an DB instances, we do several DML operation on the database.
now for such task in an application we need to keep an logging track of each task performed in PL/SQl procedure packages.
we received a design advise to add columns to track the update and delete done on each row in our tables:
- DELETED_DATE_TIME
- DELETED_BY
- UPDATE_DATE_TIME
- UPDATED_BY
In our architecture, the application can only access functions/procedures to access/modify data. Each function logs the action, the executed sql statement, oracle error, user terminal, and the user into a unified log table by using v$ tables to create a general log function that is called after execution or error.
The only advantage is that it will be easier to know the delete and last update information faster versus space and design modification.
