Database Recovery Concepts

The process of solve any type of database failures, quickly and without data loss and keep database high available is called database recovery.The main elements of database recovery is the most recent database backup.If you maintains database backup efficiently, then database recovery is very straight forward process.

The components and technologies of database is to configure to minimize or no data loss and keep database for open, includes

* Checkpoints

* Control file

* Online redolog files

* Archived redo log file

* Flash Recovery Area

Recovery Technologies

* Database Flash back technology

* Open database in Archive log mode

* Implement database high availability features like RAC, DATAGUARD,steams etc.

Components of database recovery

Checkpoints:- Checkpoint (CKPT) in oracle database is a mandatory background process. This process works in concert with the database writer process (DBWn) to manage the amount of time required for instance recovery. Checkpoint in oracle occurs when manual or automatic log switch occurs. FIRST_START_MTTR_TARGET parameter can be adjusted to control checkpoints as a result to improve instance recovery.

Control file – Control file is a metadata repository for database. It keeps all information about structure of the database. Control file is a very critical for database operation, so as being a DBA,you should maintain at minimum two copies of control file ( Oracle recommend three ) and save these in a different disk to same the control file disk failures.

Multiplexing control file

* Through Init.ora

* Through SPFILE

Multiplexing control file on init.ora file though CONTROL_FILE initialization parameter

CONTROL_FILES =(‘/u01/app/oracle/oradata/prod/ctlorcl01.ctl’,’/u02/app/oracle/oradata/prod/ctlorcl02.ctl’,’/u03/app/oracle/oradata/prod/ctlorcl03.ctl’)

Storing control file into multiple location,it protect control files from single point of failure. In multiplexing control file configuration, Oracle updates all the control files at a time, but uses only one,first one listed in the CONTROL_FILES parameter.When a single controlfile is corrupt, then DBA can simply copy a good one to that location or other location and make changing in the CONTROl_FILE parameter in init.ora file, resolve the issues.

Through SPFILE

We can dynamically set or change the location of the control file using SPFILE concept using the following command.

SQL> ALTER SYSTEM SET CONTROL_FILES =

‘/u01/app/oracle/oradata/prod/ctlorcl01.ctl’,

‘/u02/app/oracle/oradata/prod/ctlorcl02.ctl’,

‘/u03/app/oracle/oradata/prod/ctlorcl03.ctl’) SCOPE=SPFILE;

The parameter will get effects when restart the oracle instance.

Multiplexing redo log files

The information in the online redolog files are very important for database recovery. For safe guard these files against any kind of damage you can configure multiple copies of online redolog files in different disk location. All multiplex copies of redolog files are same in size and keep in a group. Each redolog file in a group is called members. LGWR background process, writes redo information to all identical members of a group,It is a best practice to protect redolog file from single point of failure. When multiplexing redolog files, members of a group should keep in different disks so that one disk failure will not affect the normal database operation.For normal database operation at least two redo log groups is required.

Creating new logfile group

We can create new redolog groups using the following command.

SQL > ALTER DATABASE ADD LOGFILE

GROUP 4 (‘/u01/app/oracle/oradata/prod/redo0401.log’,

‘/u01/app/oracle/oradata/prod/redo0402.log’

‘/u01/app/oracle/oradata/prod/redo0403.log’ ) SIZE 10M;

We can add new member to an existing group using the following command.

SQL> ALTER DATABASE ADD LOGFILE MEMBER

‘/u01/app/oracle/oradata/prod/redo0401.log’ TO GROUP 3;

Renaming Log members

Following steps to be follow to rename log members

1. Shutdown database.

2. Copy/rename redolog file to new location with operating system command

3. startup database with STARTUP MOUNT command

4. Execute SQL> ALTER DATABSE RENAME FILE ‘oldfilename’ TO ‘newfilename’

5. ALTER DATABASE OPEN

Dropping redolog groups

SQL> ALTER DATABSE DROP LOGFILE GROUP 3

Fix Your Corrupt PowerPoint Presentation by Using MS PowerPoint Recovery

Microsoft Office is one of the most common and popular software programs among all computer users. It is a software suite that contains several desktop applications for multiple purposes. As a computer user we use these applications on a daily basis. MS PowerPoint is one of them, which is used for creating and designing high-class presentation files. We all know the importance of presentation. It is widely used in almost every sector, for example:

  • For marketing promotion or corporate training session on businesses or large enterprises.
  • For teaching or training purposes in education sectors.

MS PowerPoint is one of the finest tools for creating presentation files. A presentation file may contain several pages, which are known as slides as they appear in sliding form. A slide of a presentation file may contain several file objects, such as: text, graphics, sound, movies and other objects. All these file objects make a presentation file more attractive and appealing. Microsoft PowerPoint saves presentation files in PPT or .ppt file extension. There are three types of file extension used by Microsoft PowerPoint:

  1. PPT: PPT file stores all presentation data in a single binary file. It is used by MS PowerPoint 2003 and its earlier versions.
  2. PPTX (Open XML): PPTX file is created by using the Open XML format. It stores the documents as a collection of separate files in compressed form. It can be opened in MS PowerPoint 2007 & 2010.
  3. PPTM (Open XML Macro Enabled): PPTM file, which is also known as macro-enabled presentation, contains embedded macros. It can be opened in MS PowerPoint 2007 & 2010.

It takes a lot of time and hard work to make a presentation file. A PPT file may be large as it contains several slides and various file-objects. Due to having a large size and complex structure it may get easily corrupted or damaged.

There is no computer file or application, which is immune to corruption. In the same way, presentation files are also prone to corruption. MS PowerPoint program becomes unable to open or read a corrupt file. There could be several unforeseen factors behind this corruption. Virus infection, unfinished or abruptly system shutdown, improper cancellation of presentation files or application, unexpected crash in system hard drive, software malfunction, human errors or mishandling a presentation, etc. are some of the common reasons of corruption. While opening a corrupt presentation file we may face some errors. Errors are the perfect indication of file corruption. Some of the most common errors are: “This is not a PowerPoint Presentation” or“File is corrupted or damaged”.

Whenever a file gets corrupted or damaged we need to repair it. We can use “Open and repair” to repair corrupt file, It is a built-in repair feature provided by MS Office to repair corrupt documents. It is one of the easiest and effective solutions to repair corrupt files. The steps, which are mainly required for this solution, are shown below:

  1. Open MS PowerPoint program. Click on Office button (on top of the left side).
  2. A list will be appearing. Click on Open.
  3. A small window will pop-up. Select corrupt file from the system directory.
  4. Click on the arrow of Open button. A list will be scrolled down.
  5. From the list, click on Open and repair. After some seconds, the file will be repaired and opened.

Note: Though this solution efficiently works with corrupt files, but if it does not work we must try the following solutions.

  • We should try to open a corrupt file in OpenOffice Impress.
  • We should try to open a corrupt file in MS Word. If it gets opened, we can recover at least the text part of the file.
  • We should try to import the slides from the damaged file into a new file.
  • If these solutions do not work, then we may use a third-party recovery tool for corrupt files. MS PowerPoint Recovery consists of PPT, PPTX and PPTM recovery tool, which can easily recover our data from corrupt PPT, PPTX and PPTM files. It does not overwrite or replace the old document. It creates a new file and saves all the recovered data into it. The tool works in self-describing mode as it is equipped with an automated wizard interface.

The Acer D2D Erecovery 101

Disclaimer: First of all backup your system before launching you in any hazardous operation, some of the operations to come can cause data loss. Any modification and/or damage done on your laptop will be under your responsibility.

As you know now the Acer laptops and those of other manufacturers are now delivered with a restoration system installed in a hidden partition (PQservice for Acer)on your hard disk. Normally this system launches out while pressing simultaneously keys ALT+F10, but sometimes that does not function.

What’s the problem?

There are many possible causes, but most common are:

A The function D2D was disabled in the bios.

Solution: Enable the function by pressing F2 during the boot to access the bios menu and change the setting, then reboot and press keys ALT+F10 during the starting of the laptop.

Note: For all the following solutions take into account the Max advice, I quote Max now, a contributor in my site «But I want to mention the way I sorted out the thing, because it’s very rarely mentioned on the web. All the methods to repair the D2D Alt+f10 issue are knowledgeable and smart but all of them forget to say a fundamental thing:

first of all you have to rebuild with a partition soft the D:Acerdata FAT32 empty partition that almost everybody deletes cause is usually empty. Simply doing it, everything turned fine and the recovery worked perfectly.»

Yes much of attempts to restore fail because of this condition.

B An other common problem the Acer Master Boot Record (MBR)is damaged, or replaced by the MBR of another system. You can reinstall the Acer MBR if the partition PQservice is present or if you can have access to the necessary files.

Solutions:

FIRST

On a functional FAT32 Windows system the partition table values are OC or OB for installable FAT32 system files and 12 or 1B for Hidden FAT32 partition, for a NTFS system the known partition table values are O7 for installable NTFS files system and 27 for Acer custom hidden NTFS partition:

1. Go in the bios and disable the D2D recovery option.

2. Download partedit32.

3. Identify the PQservice partition by its size (there is an information box at the bottom of the partedit window) it is the small sized partition approximately 4 to 9 Go.Once made change the type of your partition into 0C(FAT32) or 07(NTFS) and save. Reboot and now you should be able to navigate inside the PQservice partition.

Search for these two files:

mbrwrdos.exe

rtmbr.bin

(The name of these two files can be different sometimes)

When localized open a command prompt windows as an administrator and enter this command “mbrwrdos.exe install rtmbr.bin”, to install the Acer MBR. Close the command prompt, reboot again your laptop, reactivate the D2D recovery in the bios. Now ALT+F10 should work and run the Acer Erecovery when the laptop start.

SECOND

Somebody who tried to follow the first method but did not succeed to find the 2 files found another solution to restore the partition.

Use partedit32 to locate the partition pqservice(on aspire 5920g,its the larger 9 gb partition)

Change the partition type to 07(Installable NTFS),reboot.

After reboot,go to the windows computer management and mark the PQservice partition as active then reboot again.

Voila!! You can now proceed to the road to recovery

THIRD

On a nonfunctional Windows system.

Download the Ultimate Boot CD(UBCD) run it choose in the menu:

-Filesystem Tools

-Boot Managers

-For me GAG functioned well, but you can choose any of the other boot loader, you will recognize the PQservice by it type(hidden).

Just install any boot loader and use it to boot into the PQservice to start the Erecovery restoring process.

C The last problem: You replaced your hard disc( in this case PQservice is not present any more) or your partition was erased or damaged.

Solution: I hope that you burned the Acer restoration CD/DVD when it had been asked to you at the time of the first use, cause if you did not previously make a backup of your laptop by making a disc image, it will not be possible to use the Acer Erecovery.

Let us give the last words to Max:

«Problem Sorted Alan. And you’re right that an external drive for data backup it’s all important. Yes I have it and backed-up my data before starting messing up… »

Delete Browsing History – How to Clear & Permanently Delete Cookies and Cache From Your Web Browser

It has always been pretty simple to delete your Internet browsing search history. Your favorite browser, whether it is Internet Explorer, Firefox or some other, has long come with the option to delete your Internet, web and browser search history and to clear cookies and memory cache. The trick is your simply knowing what to do.

Now, remember that as in deleting other files, these files are not permanently erased until they are written over, so there are numerous special programs out there to permanently erase your search and Internet history. However, while most users do not know how to erase the history, even fewer know how to retrieve it, so using these built in functions is going to be successful for most computer users.

Most people surfing the web still use Internet Explorer. On the top menu, simply click Tools/Options/Internet Options/General. Then click “delete files”, then click OK. Finally click “clear history”, then click Yes when prompted.

Safari users have it easy. Simply click History on the top menu, and then click Clear History on the bottom of the list that appears. Just in case you did not know, Safari is now freely available for Windows users. It is one of the best browsers when it comes to protecting your search history and enabling private browsing.

If you are a Mozilla FireFox user, you will choose Tools/Options/Privacy/Clear. It is a piece of cake, right?

AOL is just as simple…Settings/Preferences/Toolbars and Sounds/Clear History Trail Now.

Granted, having to choose “toolbars and sounds” does not sound intuitive, but it does bring up an important point. If you have toolbars on your browser, like the Google, Yahoo, or Alexa toolbars, those also keep your search history for future reference…which is actually quite handy when you are trying to find something again and cannot remember what search term was successful.

However, if you are trying to cover your tracks, you do not want that information left there for prying eyes. As an example, click the Down arrow to the right of where you enter your search on the Google toolbar, and you will see your search history right in front of you. Fortunately, you will also see a link that says Clear History. Just click there, and your history is gone from sight.

All toolbars provide this sort of option, as well as an option to not even remember your Internet search history, although you might have to go into your browser and turn off the AutoComplete function.

But, again, if you want to truly make sure your search history is gone forever, you are going to need third-party privacy control software to do it. These programs cannot only clear history, cache and cookies, but they will usually permanently delete them from your computer where they cannot be recovered using undelete or data recovery software. Most programs on the market use government and military level deletion protocols, which wipe the data from your computer for good.

The Simplest Way to Unhide a Hidden Partition

After my first article on the hidden partition I realized that the solution that I brought was rather difficult for the newbies, I thus sought and tried out various solutions and programs until I find this terrible little software, I named PARTEDIT32.

This small freeware software will allow you to make visible your partition in some clicks of mouse and on the fly under Windows XP.

Just unzip and launch Partedit32 the user interface opens, simple but effective if you have more than one hard disk, choose the hard disk where your hidden partition is in the Hard Disk menu, then look in your partitions table at the column TYPE, Partedit32 has a list of the various types of partition, you can reach it by clicking the button SET TYPE.

In this example with a Acer laptop the name of the partition is pqservice and its type is 12, changes it by type 07, and save.

Now you just have to restart your computer, enter into “my computer” you have done it, now you can see the hidden partition pqservice. If you do not see the hidden partition repeat the operation but disable before the D2D recovery software into the bios menu. To open the bios hit the F2 key during the boot (note this is for Phoenix Bios check your user manual for other bios). Go to the main menu set the D2D recovery to disable, save the change restart and you have done it.

The PARTEDIT32 software is available for download at laptop support after a free registration.

After that you just have to reverse the operation to hide the pqservice partition. Note that if you want to secure documents or software you can create a partition, save your goods into and hide this partition by using partedit32.

Troubleshooting Boot Failures in Windows Server 2003

Most of us have had the problem before. You start up your Windows machine and are greeted with a cryptic error message or “blue screen of death” before your system boots. It’s a sinking feeling. You cannot access the operating system and troubleshooting the problem can be difficult. In most cases, people end up resorting to drastic measures, such as reformatting the hard drive and reinstalling the operating system. It’s not always a lost cause. Windows Server 2003 includes a number of alternative boot options to help you troubleshoot and resolve these issues.

When attempting to recover from a Windows boot failure, the first step is to get to the boot options menu. You can do this by hitting the F8 key on your keyboard immediately after the Windows boot loader screen is displayed. Once you have accessed the boot options menu, you will have a number of options which are outlined below:

Safe Mode

This option starts the operating system with a bare minimum of system drivers. Safe Mode will help you when troubleshooting boot failures caused by device drivers and registry problems. This mode does not provide networking support and most system services are disabled.

Safe Mode with Networking

The same exact thing as Safe Mode, only with Networking support.

Safe Mode with Command Prompt

This is a command line interface. It can be useful for renaming files and doing other basic command line routines. The windows explorer shell is not loaded and it’s basically just a dos prompt.

Enable Boot Logging

Boot logging starts the system normally, but it creates a detailed log of all the services and drivers that are trying to load at boot time. This can help you determine what is causing the system to crash. The default location for the log file is C:Windowsntbtlog.txt.

Enable VGA Mode

This actually loads the currently installed video driver, but uses the lowest resolution and color depth available. This is a useful option if you are troubleshooting an issue with your video card or monitor driver.

Last Known Good Configuration

You can use this option to revert to a copy of the registry that was saved during the last successful login to Windows. Although it sounds great, I can’t remember a single instance that this has ever worked for me in the past, and believe me, I’ve tried it several times.

Directory Services Restore Mode

This is only applicable for Active Directory Domain Controllers. It allows you to perform maintenance and backup recovery tasks on Active Directory.

Debugging Mode

This will allow you to hook up a working server via a serial cable to send debugging messages for analysis. This requires a great deal of configuration on the receiving end and may not be a realistic option for most people.

Finally, you can use the Recovery Console to perform more advanced troubleshooting. The Recovery Console is not installed by default. If it is not installed, you can still use it by booting to the Operating System CD and choosing the “Repair with Recovery Console” option. The Recovery Console allows you to change service startup options, create or extend volumes and or select alternative boot options.

In this article we’ve covered the multiple boot options provided by Windows Server 2003. If you are not dealing with a hardware failure you can often narrow down and correct most boot problems in Windows Server 2003 using these tools.

Operating System Options and Installation Methods

An OS is installed on the computers’ hard disk, inside an area called hard disk partition. There are several ways for installing a new operating system. The installation method is based on the system hardware and end-user requirements. Generally, you have four basic options for the installation of a new operating system:

Clean Installation

We can perform a clean installation on a new computer or in those cases where there is no upgrade path between the current operating system and the new one. This type of installation deletes all data on the hard disks partition where the current operating system is installed. A new PC requires, of course a clean installation. You can also do a clean install when the current operating system installation has corrupted files or does not work properly.

Upgrade Installation

Sometimes, it is also possible to perform an upgrade. When you perform an upgrade, OS configuration settings, installed programs and data are preserved. With this installation you have nothing to worry about, because you will not lose any personal data. You will just replace the old operating system files with the new, upgraded files. However, keep in mind that after the upgrade the applications and drivers that are incompatible with the new OS will not work as expected.

Multi-boot Installation

Another option is to install multiple operating systems on a single computer. You can install each OS inside a different disk partition and this way every OS will have its own files and configuration settings. On multi-boot installations, the users see a menu when they open their computers and they have to select the desired OS. Of course, only one operating system can run at a time.

Virtualization

This is relative new technique that is often used on servers. With virtualization we can run numerous copies of an operating system on a single set of hardware and create this way several virtual machines. Every single virtual machine works like a separate computer. This technology makes a single physical hardware resource to appear like multiple logical resources.

Before starting any operating system installation you have to make sure that all the hardware is certified to work with the new operating system. Also confirm that the hardware resources meet the minimum installation requirements. Moreover, when you perform an upgrade it is a very good practice to perform a virus scan before starting the installation and a complete full backup of all your personal data.

One method that helps you protect your data is this: Create multiple partitions on the hard disk and install a different OS on each partition. Then copy all your data inside an empty partition that does not contain an OS. This way you can upgrade the operating system without the risk of losing any data. Backup and recovery of data files is also easier with this design.

It is also important to decide the type of file system to use. The file system controls how the OS stores and tracks the files. There are several different file systems available. The most well-known are: FAT 32, NTFS, HPFS, ext2 and ext3. Every operating system is designed to use one or more of these file systems. There are advantages and disadvantages on every file system. Careful consideration should be made to the type of file systems supported by the selected OS and the benefits of each.

You can find several programs to modify the partitioning structure and file system of a hard drive after installation, but it is better to avoid them if possible. When modifying either the file system or partition structure on a hard drive, data loss may result. Careful planning can help preserve the integrity of the data.

The History Of Data Deduplication

Data deduplication has been around, at least in its most primitive form, since the 1970’s. It initially started because companies wanted to store large amount of customer contact information without using a large amount of storage space. One of the first ideas was to go through and remove duplicate data. For example, a company might have an address for shipping, and an address for billing to a given customer. In these cases, those identical addresses would be combined into one file. This was done by data entry clerks who would review the data line by line and get rid of duplicates.

Of course, the amount of personnel needed to do this was extensive and it took a very long time. Sometimes, the data deduplication process would take months to complete. However, considering that most of this occurred on hard copy, it wasn’t a major problem. The big problems cam along when computer use became widespread in office environments.

With computers in wide use and the explosion of the internet, the amount of data available exploded as well. Backup systems were created to ensure that companies would not lose all their data. As time went by, floppy discs and other external hardware was used to store this data. Unfortunately, this data would soon fill up these discs and the amount of space to store this data was extensive.

With cloud storage and other alternative storage options, companies began moving their storage to a virtual environment. They also moved to disk-based storage over tape based, simply because it was low-cost and required less space. However, these storage options were expensive and difficult to manage as data grew. The same data would get saved over and over again. This redundant data was not needed and took up valuable storage space.

Companies might have customized their backup plans to eliminate duplication, but there was no fast way to do this. That is when IT professionals began working on algorithms to automate the data deduplication process. They generally did this on a cases by case basis, with their goal to optimize their own backup files. Their algorithms would be customized to meet their own individual needs.

There was no one company that came up with the idea of data deduplication. Instead, the need to find a way to reduce duplicate files was a common need in the industry. There were many computer scientists who advanced data deduplication technology significantly, but there is no one scientist who was solely responsible for it. While many have claimed credit for the term ‘data deduplication’ itself, no one person can claim credit for the idea itself.

Instead, the creation of data deduplication algorithms was more of a compilation. People in the IT industry saw a need to reduce data duplicates and they filled that need to reduce those duplicated file by creating algorithms. As data increases, people will continue to find ways to compress data in a way that makes it easy to store.

How To Quickly Make A Bootable USB Stick With FreeBSD

Install FreeBSD, or use an existing FreeBSD installation, and follow these steps:

1) First, you need to prepare and format your USB stick:

fdisk -BI /dev/da0
bsdlabel -B -w da0s1
newfs -U -O1 /dev/da0s1a
boot0cfg -v -B da0
(“-U -O1” [“O” like in Olympus, not zero] is for UFS1 which provides much faster copying than UFS2; if you decide for UFS2, type “-U -O2” – but expect that the copying will be slower)

2) Then mount it: mount /dev/da0s1a /usb
3) Copy all directories (FreeBSD) to the stick
4) After copying, modify the /usb/boot/loader.conf (explained below)
5) In the /boot directory on your USB stick you must have MFS (Memory File System – mfsroot.gz), which you will make (instructions are below)
6) Modify your /etc/fstab in MFS and put the following line (only) there:
/dev/md0 / ufs rw 0 0
7) After you boot your computer with the stick, you will be in the MFS environment from which you will mount your USB stick with mount_nullfs (described below)

Modification of /boot/loader.conf on your USB stick

You must have the following lines in your /boot/loader.conf (some lines are optional):

mfsroot_load=”YES”
mfsroot_type=”mfs_root”
mfsroot_name=”/boot/mfsroot”
nullfs_load=”YES”
splash_bmp_load=”YES”
vesa_load=”YES”
geom_uzip_load=”YES”
geom_label_load=”YES”
bitmap_load=”YES”
bitmap_name=”/boot/splash.bmp”
snd_driver_load=”YES”
kern.maxfiles=”25000″
kern.maxusers=”64″
vfs.root.mountfrom=”/dev/md0″

# Additional filesystem drivers

udf_load=”YES”
linux_load=”YES”
fuse_load=”YES”
ntfs_load=”YES”
ext2fs_load=”YES”
reiserfs_load=”YES”

Making your own MFS

FreeBSD, after the kernel boots, can use the root file system in memory (mfsroot_load=”YES” command in /boot/loader.conf will do the trick). To build such a memory file system, type the command:
dd if = /dev/zero of = mfsroot bs = 1024k count = 42

The mfsroot file of about 40 MB in size will be created. You need to format it, mount it and copy the most important files into it from your FreeBSD system (/bin, /sbin, /etc, /root….):

mdconfig -a -f mfsroot md0
newfs /dev/md0
mount /dev/md0 /mnt

Once copied, you must unmount it and gzip it: gzip mfsroot

Optionally, you can chroot it to see if everything works, then copy the mfsroot.gz to /usb/boot onto your USB flash drive (or disk). If you think it may be a problem to pick the most important files for your MFS (from your FreeBSD installation), search for mfsbsd in Google and either use its toolset or the MFS image alone (contained in the downloadable ISO of mfsbsd).

After booting from the USB stick (you will jump into MFS), you must mount the physical USB stick:

/sbin/mount -o ro /dev/da0s1a /usb
/sbin/mount_nullfs /usb/boot /boot
/sbin/mount_nullfs /usb/usr /usr

The above commands will help you use the big /usr directory on your USB stick instead of the /usr dir in MFS. mount_nullfs /usb/boot /boot is optional, as in your MFS/boot directory only the following files are needed for the little MFS to boot (/boot/kernel directory in MFS): geom_label.ko, geom_uzip.ko, zlib.ko a their debug symbols (zlib.ko.symbols, etc.). By mounting the /usb/boot dir via mount_nullfs into the /boot directory in your MFS you will be able to load kernel modules.

Entourage Repair to Fix "Not Enough Memory" in Microsoft Entourage

Are you unable to access your Entourage Inbox, Drafts folder, Deleted Items folder, and any of your subfolders of Inbox? You get memory errors while accessing items from your database. This behavior makes all your precious data inaccessible and leads to severe data loss. At this point of time, you need to opt for Entourage repair solutions to get your precious data back.

In a practical instance of this problem with your E-mail client, you may encounter the below error message while accessing data-

“Entourage cannot open the item due to an error. Not enough memory.”

This behavior renders all your precious data inaccessible. In order to recover Entourage database in such cases, you need to find out the cause of this issue and fix it using appropriate solutions.

Root of the problem-

Unfortunately, the above error is not caused by memory problems. This is actually a wrong description on generic error, which can be caused by number of other things, such as-

  • If you get this error while receiving emails, it can be due to a corrupt message.
  • The fonts are faulty or damaged.
  • Your Mac RAM (Read Only Memory) is either low or damaged.
  • Entourage database is either corrupt or unrecognizable.

Resolution-

  • Log into your account using web browser and remove the damaged items.
  • Install new fonts or remove the faulty fonts.
  • Replace or Upgrade your Macintosh RAM.
  • Restore your database from the most recent backup. You are recommended to repair Entourage database from backup only if it is updated.

If you cannot perform Entourage database recovery using any of the above methods, you need to opt for Entourage recovery software to get your data back. Entourage repair software are capable of retrieving inaccessible data in all data loss situations.
