How To Solve Table Index Corruption In Exchange Server

The main repository of mailbox data in Exchange Server is the .edb file that is primarily composed of b-trees. Since a b-tree is allowed to have a considerable depth, b-trees deploy indexes to permit quick data access. In Exchange EDB, there are few ancillary trees that hold table indexes to work with the main tree. If these indexes go corrupted, the entire table and sometimes, the whole database become unusable. This is what we refer as logical database corruption. In critical situations, when this type of corruption is not limited to index page corruption, you need to implement Exchange Server Repair solutions.

To understand such potential problems with Exchange database further, consider the discussed scenario and error. When using Exchange Server 2007, you can encounter event 467 logging in the application log. Additionally, on viewing the description section of the same event, you receive an error that reads similar to below:

Information Store (number) Index [index name] of table [table name] is corrupted.

This error typically indicates a corrupted index in the Exchange store. As symptoms, you might observe access violations and repeated crashes. Also, this type of corruption might go undetected for long without any symptoms. Even the Exchange-aware backup may fail to detect this corruption. Event 467 suggests logical corruption at Database (JET database engine) level and is exhibited when JET engine touches this location in the database while reporting it as event 447. For specific root causes, one needs to view the application and system log cautiously as these errors can damage your data badly.

Solution

Following suggestions can help you isolate the depicted problem:

1. If corruption is limited to index leaf pages and not with the database pages, running Eseutil /d (offline defragmentation) alone can perform Exchange Server Repair.

2. In critical problems, you may need to use ExMerge utility to move the mailboxes to a new, blank Information Store.

3. The Exchange Server might be affected from page or database level corruption together with index page corruption. In such cases, you can execute Eseutil /p and then Isinteg -fix commands as Eseutil /d command may not work. You can further use ExMerge tool to put the database again in use.

4. To avoid data loss problems due to Eseutil /p utility, it is however, recommended to opt for a safe third-party Exchange Repair utility.

The Exchange Repair is a professional utility that repairs corrupted Exchange EDB file and restores the mailboxes in separate *.pst files. The Exchange Server Repair product is easy to use with its self-explanatory interface. Designed for Exchange Server 5.5, 2000, 2003, and 2007, the tool is also competent to recover deleted mailboxes.

Directv Hd Lnb Upgrades-getting Crystal Clear High Definition Programming

When I bought my first LCD widescreen TV, I thought that the standard resolution was alright. Then curiosity killed the cat. I decided to invest on a HD LNB.

An LNB is a low noise block converter. If your not a techie, it’s the feed horn, or the part of your satellite dish that receives the signals. If you’re planning to receive HD TV, you have to invest in a special LNB.

THE BEAUTY OF HDTV

After my receiver was updated, I tested out an HD channel. After doing so, it was so hard to turn back to the standard resolution channels. HD allows the programs to be more vibrant and have more clarity.

If you’re using a regular CRT (tube) television, you probably won’t notice that much difference. However, if you have one of the newer widescreen TV’s (37 inches and up), the difference will be obvious. I’m sure that you will find HD programming as stunning as I have.

INVESTING ON A DIRECTV HD LNB

If you’re looking to upgrade your current DirecTV satellite system, you’ll have to consider the type of dish you have. There are 2 main dishes that can have HD LNB upgrades or replacements. They are the Phase II and Phase III dish.

If you have the Phase II dish, you can get a Sat-C upgrade. It’s a simple kit that attaches and additional LNB to your current Phase II setup.

For Phase III owners, you’ll have the 3 LNB block with HD compatibility.

Basically, these 2 dish types allow you to get channels from satellite 110. The previous satellite configuration allowed the consumer to receive channels from 101, 110 and 119 degrees.

FOCUSING ON THE FUTURE OF HD

With technology constantly changing, you’ll have to keep up if you want the best in high definition. If you’ve decided that all you want is HD, you’ll want to replace your whole system. This replacement includes the dish with LNB and the receiver.

When DirecTV introduced MPEG-4, equipment upgrades were necessary. With MPEG-4, consumers would be able to receive more channels since there was more compression. You’ll need the DirecTV AT9 Ku/Ka Dish and a HD-compatible receiver such as the DirecTV H20.

With this MPEG-4 system, you’ll be able to receive channels from more satellites. DirecTV satellite 99 and 103 degrees will allow you to receive even more HD channels and extend your local HD channel reception.

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

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,

Advantages Of Ku Band Satellite Systems And Isp Technology

There are many renowned satellite service providers who offer, earth station leasing and transponder leasing services to meet the short-term broadcasting and transmission requirements of the global clientele. With these services, one can easily increase the coverage areas and subscribers through Multipoint solutions, Point-to-Point solutions, and Broadcast and Multicast applications, to link remote provinces to the main switching network. You can select the desired bandwidth for the transponder leasing services. You can opt for C band, eKU band, DBS band, Ku Band, extended C band and Ku band satellite system for various transponder capacities. The best part is that transponder leasing facilities can also be availed for occasional short term audio or video transmission applications like live TV broadcasting of special events, program transmission or backhaul services etc.

The most popular band is satellite communication is Ku band. Unlike C band, Ku band satellite system is not restricted in power so as to prevent interference with terrestrial microwave systems. Thus, the power of its uplinks and downlinks can be easily increased as per the requirements. Higher power also means that one can use smaller receiving dishes. This is because the function of the dish antenna is to collect the incident waves over an area and focus them all onto the antenna’s actual receiving element, thus, if the waves are high in intensity, then less dish antenna will be sufficient to collect and achieve the same intensity at the receiving element.

With the revolutionizing changes occurring in the satellite technology, more and more people are turning to global internet service providers. Most reliable internet service providers offer high-end Internet Protocol Paradigm like dial-up, DSL, cable modem, wireless or committed high-speed connection, with the help of data transmission technology.
