Can I disable logging for session in Oracle 10g?

I use a procedure to delete a lot of row for an application repeatedly. Because the DELETE statement is time consuming and the data don't need to be archived, I decide to use the nologging option.
How to do it?
What is the best choice? Can I disable logging from session in Oracle 10g?
Thank you

Hi,
"Delete" without generating redo-log is not possible.
If you are on 10g, one way of making this thing efficiant is partition the table, with range-list partitioning. Partitioning existing table will be an excercise in itself, but that will be one time activity.
In partitioned (or sub-partitioned) tables, you can truncate a partition (or subpartition). That won't generate any redo log (or very very less redo log) and that runs in seconds.
In your case if you range partition INCOMING table by datetime (1 partition per day) and list sub-partition it by STATUS, that would help.
Another approach is, if you are deleteing, say 80% records every day and leaving 20% (or very less) records. What you can do is, partition the table only by range on datetime. Then, every time you want to delete data, copy the rows you want to keep in some other table (or temporary table), truncate partition for that day and insert rows back (which you want to keep).
I have done a similar thing and it works very quickly and generates very less redo log. Redo log generated in case of truncating partition or creating new partitions is just for Oracle internal commands (like data dictionary update etc).
Have fun.

What is process in oracle give some examples

what is process in oracle give some examples

The tem "process" has multiple meaning in Oracle but most likely you probably are referring to the Oracle background process used to perform the work for an Oracle session. These are in fact OS processes spawed by Oracle using fork on UNIX/Linux and would be task thread on Windows. You can find infomraion on these proceses via the v$process view. You join v$process to v$session to see the front and backend processes for a connection to Oracle.
The Concpts manual describes Oracle process Architecture:

Open Independent Mulitple sessions with oracle in a LabVIEW exe

Is it possible to maintain different sessions to same database from within a labVIEW exe. I need to have a server to which multiple clients connect. Server starts handler for each client and each handler needs to connect to the database and transact on its own and get some data for the client. This is basically to achieve concurrency. But the operations are happening only sequentially. Please help.

Your two other postings:
"Parsing an SQL statement coming in the way of reentrancy."
"NEW!! Parsing an SQL statement coming in the way of reentrancy."
I put a link to all your postings here to help others on the discussion forum to follow your questions.
The problem may be that your server has a single CPU and that it can only do one thing at a time. Another limitation may be the abstraction layer for your database. What version of the Oracle d
b are you using? Do you have this problem across computers or just on a single machine?

OpenWorld: Explore What's New in Oracle Fusion Middleware's Web Frontier

Hello All -
We have a dedicated Web Tier session at the upcoming OpenWorld in San Francisco, Moscone West.
Oracle Web Tier has comprised Oracle HTTP Server and Oracle Web Cache. Now, with the Sun acquisition, the Oracle Web Tier product line includes Oracle iPlanet Web Server (formerly Sun Java System Web Server) and Oracle iPlanet Web Proxy Server (formerly Sun Java System Web Proxy Server). The new app_grid_plugin consolidates some past plug-ins to connect to the Oracle application grid. Oracle HTTP Server (based on the upcoming Apache 2.4) and Oracle iPlanet Web Server Release 7.1, part of Oracle Database 11g Release 2, will introduce new capabilities. This session showcases these new developments in scalability, security, and manageability best practices for deploying Oracle Web Tier in Oracle Fusion Middleware production environments.

"What is BPEL y we require that."
Other people cited good "what is BPEL" technical information. In plain words, BPEL is an XML-based language to implement business processes, to integrate data from various applications so everyone can see it whether it is originally flat-file, XML, messages, legacy systems, whatever.
Why "we" require it:
Part 1 (Managers): Allows integrators to quickly build systems based on business process diagrams by non-technical business analysts. Makes data from many applications available to the business, particularly for "real time" monitoring of how the business is doing.
Part 2 (Engineers): Allows us to get process specifications from the business users and rapidly build applications. Once an XML and/or web-service interface is created for a legacy application, we can re-use it immediately to integrate with other systems.
I suspect others will clarify/add to this.

Andy

Limit open connections per each database session in Oracle 11

Hi for All,
Please, I would like to know what the limit of connections per session in Oracle 11. This issue is relevant to the use of UTL_TCP for connections with ATMs. Also, someone would have some other approach or suggestion of communication architecture with Automated Teller Machine?
Regards,
Edited by: user11118871 on 04/02/2010 07:30

I suspect Spotlight is showing you the PGA plus the entire mapped portion of shared memory or the total of all shared memory pages visited. On HP-UX these are the kind of numbers you would get from ps, which may be Spotlight's source for the data.
The glance utility of HP-UX is a more useful way to obtain detailed information on process memory usage.

How to block Sql Plus sessions in Oracle 10g

Hi,
I want to block all sql plus sessions in oracle 10g, as we have a application and we need each and every one to use this application not the sql plus session.
Kindly update us as soon as possible. and also thanks in advanced.

Understand the concept Karl, but a layered defense seldom works in the IP world. If I manage to get through the firewall, then how can you prevent me access, at IP level, at any other ISO stack layer? If you manage to get through, then your firewall policies could just be too weak :) at least you must have some kind of an IDS infrastructure in place..
what I mean is, you can have infinite number of threats.. and this will be part of your Risk Analysis. Determining all possible threats to the assets, what are being protected and their associated value, and predicting the rate of occurrence.... with all of these you could probably come up with contingency plans and incident response.. And most of all, you should not ignore the fact that people are creative, ingenious, and curious, and they'll prove this to you by testing your security implementations. So you'll have to periodically evaluate your security.. that's why there are audits.. Also, you must balance Security, Performance, Usability, and your Budget.
Yes, you can argue that if the entire firewall goes down (thus no IP defense), then something like DBV (or even denying IPs in sqlnet) can provide some defense. But is that not then a case of too little too late? It's better too little too late, than no protection at all... Imagine if there's no DBV, or if you have not implemented the concept of "Least Privilege"? or if the backups and exports are not encrypted? That would be more devastating.. that's the importance of database security options and features in providing "defense in depth"
I question just what purpose and how effective IP packet security is at higher layers. It can never substitute doing this instead at firewall level. Well, it's not all about network security. All facets must be considered and the inter-relationships should be understand. Like the core information security and access management, physical and personnel security, training them, etc... And all of these are equally important in providing a secure ecosystem
As for security that relies on the client to pass secure data (like executable name or o/s user name)... all this can easily be spoofed. Even if the app and Oracle driver are somehow digitally signed and these signatures can be verified on the server side, we only need to look at Vista to see how secure this really would be. Microsoft attempted to encrypt every single h/w and s/w layer from the physical DVD track to the pixel on the monitor.. and this was defeated. And this was done as o/s kernel level. It is less complex to hack at driver level and even trivial to do it at application level.Security is about risk management. Blocking SQL*Plus does not negate the risk of SQL from the wild being run on a production server. For example, the client is a VB client using ODBC. It is easy to create a proxy that accepts the ODBC connection from the VB client and proxy the OCI packets to the real Oracle server. Now you have a man-in-the-middle than can inspect every single SQL call made to Oracle, and inject any PL/SQL or SQL code it wants.
Security is far beyond writing a login trigger to deny SQL*Plus sessions and calling that a defense. >
Yes I agree with you. That's why there are independent organizations and regulating bodies that provides security best practices, to give us a headstart on comming up of strong security policies.
And one of my favorites is the one provided by IASE (sponsored by Defense Information Systems Agency) where there's lot of content regarding hardening and policies

Title:      Java SE for Embedded Meets Oracle Berkeley DB at the Edge
Abstract:      This session covers a special case of edge-to-enterprise computing, where the edge consists of embedded devices running Java SE for Embedded in combination with Oracle Berkeley DB Java Edition, a widely used embedded database. The approach fits a larger emerging trend in which edge embedded devices are "smart"--that is, they come equipped with an embedded (in-process) database for structured persistent storage of data as needed. In addition, these devices may optionally come with a thin middleware layer that can perform certain basic data processing operations locally. The session highlights the synergies between both technologies and how they can be utilized. Topics covered include implementation and performance optimization.

What happen during shutdown oracle database

Dear All,
i have a questions and i enclosed some suggestions for the answer because I'm confused about the answers :
What happens during shutdown oracle database :
and the suggested answer :
1- When shutdown the database with NORMAL or IMMEDIATE option : the database system writes check point before shutting down the database .
2- when you shutdown the database with the IMMEDIATE , option , open transaction are rolled back before the database is shutdown .
3- shutting down the database with abort always requires an instance recovery at the next startup .
please suggest the right answer .
Regards

Hi Anwar,
When you close a database, Oracle writes all database data and recovery data in the SGA to the datafiles and redo log files, respectively. Next, Oracle closes all online datafiles and redo log files.
When you terminate the instance of an open database/use abort command to close and completely shut down the database the writing of all data in the buffers of the SGA to the datafiles and redo log files is skipped. The subsequent reopening of the database requires recovery, which Oracle performs automatically.
I hope this will help you out to understand the process.
