Causes Of Error 823 In Sql Server And How To Fix It

Do you encounter Input/Output (I/O) errors while accessing a MS SQL Server database? Are you unable to run queries on or access data from MDF (Master Database File)? This behavior indicates system or hardware problems with SQL Server that corrupt the database and renders it inaccessible. It leads to critical data loss situations. In order to extract data from Microsoft SQL Server in such situations, you need to opt for solutions.

Hardware and system problems in SQL Server are generally indicated by an error message, similar to the following one:

Error 823
I/O error detected during at offset in file ”

You come across this error message when SQL Server attempts to read data from and write data to the database files. Format of this error message can be different, depending upon the version of SQL Server.

Cause

You come across this error message, if any of the below conditions are true:
Operating system error.
I/O logical check failure.
MS SQL Server database corruption.

If any of the above situations occur, it becomes essential to perform SQL Server Recovery by resolving it, to retrieve inaccessible data.

Solution

Try out the below things to fix up this issue, as per the cause of the the problem:

Operating system error: The read Windows API (Application Programing Interface) call or the write API call is unsuccessful and MS SQL Server experiences operating system errors, which is related to Windows API call. Run operating system integrity checking tools. Following is the example of operating system error:

2003-07-28 09:01:27.38 spid75 Error: 823, Severity: 24,
State: 2
2003-07-28 09:01:27.38 spid75 I/O error 1117 (The request could not be performed because of an I/O device error.) detected during read at offset 0x0000002d460000 in file ‘e:\program files\Microsoft SQL Server\mssql\data\mydb.MDF’
I/O check failure: If specified logical data checks are unsuccessful, you may encounter this problem. Run DBCC CHECKDB to solve this issue.
Database corruption: Restore the database from recent backup. If the backed is unusable, Recover SQL database through third-party applications.

The software are powerful enough to handle most of the database corruption issues. The applications use high-end scanning methods to ensure absolute recovery. They are incorporated with rich graphical user interface to provide quick and easy recovery.

SQL Recovery is the most advanced and powerful utility that is able to effectively handle all database corruption scenarios. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It restores all MDF file objects such as tables, reports, forms, constraints, stored procedures, triggers, data types, and more.

A Brief History of Parallel Programming in Java

Concurrent programming was part of the initial Java specification, although most of the 1.x JDKs available at that time only supported concurrency at the JVM level (using so called green threads) without being able to fully benefit from the multi-core hardware. The Java language already contained the basic primitives (Thread class, wait() and notify() function calls, and the ‘synchronized’ keyword) that are still used nowdays to program modern many-core and multi-core hardware architectures.

Then progressively the JVMs evolved in order to improve mapping of to native threads (beter I/Os, faster context switching). .

As part of JSR 166, Java 5 introduced the java.util.concurrent package, which provides concurrency utilities (concurrent collections, atomic variables, locks) to ease development of concurrent programs and increase maintainability. On the performance front, the newly provided execution framework introduce a pool of reusable worker threads in order to reduce the cost of creating new (native) threads.

The next release, Java 6.0 received a small update as part of JSR 166x: mostly bug fixing and polishing, but also a few new APIs like ConcurrentSkipListMap and ConcurrentSkipSetMap.

Java 7.0, scheduled for mid 2011, will bring some new tools for parallel programming (JSR 166y), a fine-grained concurrent computation framework, some new concurrent data-structures and a new concurrent random number generator (ThreadLocalRandom). The new concurrency framework is based on the fork/join metaphor and can be used for algorithms that can be expressed using divide-and-conquer techniques. Then the work-stealing policy implemented in the framework will ensure that all the concurrent tasks are dispatched efficiently to all available threads (and thus to all available processor cores). It is also worth noticing that some other areas of the JVM are also following this trend (see for example the new thread-safe concurrent class loaders).

Some other features previously scheduled for Java 7.0 were postponed to Java 8.0 after the acquisition of Sun by Oracle (this late split is known as ‘Plan B’) and JSR 166z is supposed to cover these new enhancements. One of the main feature would be the introduction of lambda-like expressions (previously known as Project Lambda and described in JSR 335) and their use in combination with the new ParallelArray framework which provides an integration of data parallelism into the Java language.

Amazing Facts On Children And Internet Porn

Pornography on the internet must be on the top of the list for parents concerns for their kids.

I had made some really scary discovery whilst researching on how to address this issue for my home, and here are the shocking results:

Did you know?
The multi-billion-dollar pornography industry is using the Internet to tap into a new market unashamedly, the sanctity of American homes. There are 4.2 million pornographic websites. That equals roughly 12% of all websites in the world.

80% of 15-17 year olds have had multiple hard-core exposures.

90% of 8-16 year olds have viewed porn online (most while doing homework.)

29% of 7-17 year olds would freely give out home address.

14% of 7-17 year olds would freely give out email address. 26 Childrens character names (Including Pokeman and Action Man) are linked to thousands of porn links.

The average age of first Internet exposure to pornography is 11 years old.

One in five children ages 10-17 have received a sexual solicitation over the Internet.

70% of sexual advances over the Internet happened while youngsters were on a home computer.

A survey of 600 households conducted by the National Center for Missing & Exploited Children found that 20% of parents do not know any of their childrens Internet passwords, instant messaging nicknames or email addresses.

Incidents of child sexual exploitation have risen from 4,573 in 1998 to 112,083 in 2004, according to the National Center for Missing & Exploited Children.

96% of kids have gone online; 74% having access at home and 61% use the Internet on a typical day.

Twenty percent of youths received sexual solicitations. Eighty-nine percent of sexual solicitations of youths were made in chat rooms.

The report compiled for the Pew Internet & American Life Project found that nearly nine out of 10 young people, ages 12 through 17, have online access up from about three-quarters of young people in 2000.

Older teen girls who were surveyed, ages 15 to 17, are among the most intense users of the Internet and cell phones, including text messaging.

One in four children who use the Internet are exposed to unwanted sexual material.

21% of teens say they have looked at something on the Internet that they wouldnt want their parents to know.

Yikes! What on earth is happening? Pokemon character names used as links to porn sites?

Ways to Avoid Teen Pregnancies with Symbian Monitoring Software

Adolescence brings hormonal changes. Teenagers start interacting, flirting, and dating others in their age bracket. With the glamorous depiction of sex from movies, magazines, and their circle of friends, teenagers quickly try to move towards a more physical relationship. This results in unwanted teenage pregnancies. Teenagers are hardly able to cope with problems of their age, let alone a problem as delicate as handling pregnancy. Parents, teachers, health professionals, and teenagers themselves have to shoulder this responsibility.

Teenage pregnancy can be avoided by abstinence or contraception. Parents should try to delay sexual activism in teenagers until a mature age. If their teenager is sexually active, they should at least talk to them about the use of contraceptives.

The following and many other techniques are used along with Symbian monitoring software to avoid teen pregnancies.

First of all, you must monitor your teenagers with Symbian monitoring software. You should always know who they are with, where they are going, and what are they planning. The software program allows you to monitor your child’s physical location, calls, address book, photos, and messages. You should know their friends and anyone they’re dating well enough.

You should also be aware of extent of media exposure towards your teenager. Media in this context includes magazines, TV, internet, and movies. Try to control his/her media exposure to constructive and educational purposes. The program lets you know if your child is looking at sexual material on the phone.

Discourage early dating. Maturity comes with age. If you allow teenagers to date at the onset of adolescence, they can’t imagine the consequences it can have. The program lets you know if your child is breaking the dating rules you set.

Teach them how to say -No’. It is important for your teenager to enter into any relationship willfully. Generally boys may urge teenage girls to have sexual relationships with them. If the girl is strong enough and confident, she will say no to early or unprotected sex. By checking your child’s calls, you’ll know if the boyfriend is being too insistent for your taste.

Teach them how to resist peer pressure. When adolescent boys and girls start dating, an elimination process in the form of peer pressure starts. The ones who are able to find a date, join the elite of popular members. Those left out without dates are under strong pressure to get laid as early as possible. Because this pressure often comes in the form of calls or text messages, you’ll know about it immediately.

This type of cell phone monitoring software is a great helper that tells you the risks and situations that your child is going through. Using it is easy and definitively better than the alternative.

Do You Know How to Select the hardware

The hardware fittings is mainly included copper, aluminium alloy, stainless steel and irons these four types of material, and there is also a great difference between the prices. At present, the most used in the family fitment is stainless steel hardware, but the stainless steel has some shortcomings such as material impurity and easy to print out the waterlogging, and now many families start to use the aluminium alloy accessories. As we know, in fact the aluminum material some merchant asserted that is just the alloy material which contains some aluminum, also blend with some silicon, magnesium, the surface film thickness and surface treatment also will affect the price and the quality of the material. Oxidation, dull polish, electroplate, wood grain , baking varnish are the main surface treatments, and their prices are also differs greatly.

Some citizens reflect that they found some -stainless steel accessories- are made by stainless iron that is blend some iron into the stainless iron, the prices varies nearly two times. Take the towel rack for instance, the price of stainless steel one is 200 yuan while the stainless iron one is just 70 yuan, they are basicly same, but the stainless steel is brighter and the stainless iron will easily become darkened or rusted when use for a long peroid.

Besides, there are also some counterfeits that use theinferior aluminium alloy as the raw material, and the surface is plated with a metal light in order to pretend toobe the top grade stainless steel. When you tell these two materials you can beat the surface, if made a clear sound then it is mostly stainless steel, if made a tedious sound then it is likely to be the aluminium alloy.

The present home decoration are generally divided into general mirror and silver mirror, their prices are differ about 30%, the market price of silver mirror is about 80-90 per square metre while the general mirror is about 50 yuan, and their qualities are also differ greatly.

The main factor that leads to different prices is using different materials, the silver mirror colored with a bed of mercury then to mopping, and the general mirror is plated with a bed of aluminium then to mopping, the waterproof and fog efficacy decline a lot. Moreover, baking finish, stamp, tempering are also affect the mirror’s price. Get more information about the hardware here.

Iron Balance Microsoft Exchange Server 2010

Since Exchange 2010 includes the following server roles:

Server mailboxes on this server hosts the mailboxes and public folders. Client Access server in the server hosted client protocol, such as POP3, IMAP4, HTTPS, mobile Outlook, service availability and service auto-discovery. Server Unified Messaging This server connects the internal PBX and Exchange 2010. Hub Transport server is routing mail routes the internally Exchange. Edge Transport server is routing mail, which is usually placed at the boundary of the topology and routes the incoming and outgoing mail in your organization Exchange.

Standard design requires a Client Access server farm with load balancing for high availability and performance solutions. For Exchange 2010, you can use softovoy Balancing Windows Network Load Balancing (WNLB) but with the following restrictions: WNLB can not be used in conjunction with database availability groups (DAGs) – functionality allows you to sync mailboxes across multiple sites. Due to performance issues do not recommend running more than 8 Client Access servers balancing WNLB. WNLB can not detect a denial of service on servers and only works at the level of L3, ie, determines the availability of servers based on IP. That is, if the server responds to IP, but server applications do not work, you want to remove the failed server client access from the pool balance manually. WNLB configuration errors can lead to degradation of network bandwidth. As WNLB balancing exercises only at the client, with a limited pool of client addresses, for example when using NAT, load balancing between servers, Client Access does not work effectively.

All these problems are eliminates by the use of hardware balancers Brocade ServerIron ADX, which balances the load on the levels of L4-L7, with a maximum capacity per chassis up to 70Gbps, allow you to choose from a variety of mechanisms to balance and carry out constant monitoring of servers from the IP-availability and load SNMP and ending with an extended Health check up to check the response given on the application.
The joint solution of Brocade and Microsoft have passed laboratory testing in the Microsoft Enterprise Engineering Center (EEC) in the Microsoft headquarters in Redmond.

In this scheme, ServerIron ADX provides:

* Save sessions. Client to connect to one of the servers continues to work with him only within the session.
* Rules of switching content (Content Switching Rules). Through support for switching at the level of L7, ADX can make decisions on balancing traffic based on data about the URL, cookes, or ID SSL-session
* SSL-proxy – the maintenance of a secure tunnel between client and server with the possibility of balancing at the application level
Monitoring the north to control their availability and willingness to process requests.
